I just got my floppy disc version of "Quickload" updated. Alliant RL17 is showing up W/some impressive # for the 8X57 W/a 200gr Speer Hotcore bullet. About 50fps better than Vv N550 which itself showed impressive MV. At 60K it's predicting 2782 fps W/the 200gr Hotcore @ my COAL & 23 1/2 barrel length. I was getting 2730 fps Mv from Vv N550 @ similar chamber pressure. RL17 is about 1/2 the cost of Vv N550 & readily available locally.

I am getting 3,000 fps from a 25.6" Blaser R93 barrel in 6.5x284 with 140gr bullets and no pressure signs. the load is 50gr of RL17, Fed 215M primers and Lapua or Norma brass. | |||

Not sure what your COAL is, but I plugged in 3.0". W/50gr RL17 in a 25.6" barrel, Quickload predicted 2985 fps @ 60592 PSI. I wouldn't call that high pressure. GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

I have a 338-06 AI and it loves this powder. It's giving me between 60 and 80 fps over other powders. Also seems to be quite temperature resistant. And these gains come with outstanding accuracy. | |||

Yes, I read that it is temperature stable. I get oustanding accuracy W/Vv N550, but I can't get it locally & even W/O Hazmat, it's double the price of the RL17 which I can get in Rochester when I visit my Daughter. If RL17 will give me the 1/2 MOA acccuracy of Vv N550 I would buy/try it even W/O the extra 50 fps that Quickload predicts. A 200gr 323 bullet @ 2785 fps is nothing to sneeze at. Over 3400# Me & 3" PBR to over 270yds. I did predictions for my (now dismantled) 8mm-06 AI & it predicts 2900 fps W/a 200gr Accubond @ 6200K from a 24" barrel. Now, that's a pretty big hammer! I may have to get one of my M29 8X57 barrels rechambered & dust off my 8mm-06 AI dies. GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

In my 338 Win Mag with 160gn Barnes TTSX bullets, a maximum load of 81gn Reloader 17 gives me 3390 fps and about 0.8MOA accuracy for 3 shots. It is a very good powder. For safety take care to work up from around 75gn with 160gn bullets in your 338 Win Mag if you want to try and duplicate that load, as it is a maximum in my rifle, and as you should be aware different rifles can give very different pressures with similar loads. | |||

I was doing some ladder tests this week and tried it with some 140grNBT in a .280IMP. I got nothing worth pursuing out of it with that combo; RL19 and 22 were the winners. I'm going to try it again though with some 160gr Accubonds. | |||

This is sounding better & better. More MV @ safe pressures & outstanding accuracy. I found Vv N550 to be similar in gains of MV/accuracy compared to more traditional powders. Now, it seems that Alliant has raised the bar again. 3450ft #s from an 8X57 really puts it in the all around capability realm for any North American game when something like a Swift A Frame is utilized. W/a 220gr Hornady the 8X57 can still top 2600fps using RL17. I really have to get that 8mm-06 AI back together now.

Wildcat I have tried RL17 in my 9.3x64 with 286 gr partitions. RWS brass WLR primers and 70 grs of RL17 with the bullet seated to a COL length of 3.345". Very good groups. Could I get you to run that in your quickload to see what it says for velocity and pressure. How does that compare to 76 grs of IMR 4350 with the same bullet and same COL? Thanks | |||
|
| one of us |
24" barrel 101.1% load Density, 70gr RL17, 286gr Partition 3.345 COAL: 59,712 psi @ 2646 fps Same criteria W/4350 is @ 115.8% load density W/76gr & it's off the charts @ over 80K. Drop to 105% LD, 68gr IMR 4350 & pressure is 59489 @ 2535 fps RL17 = 111 fps more Mv @ similar chamber pressure. A word of caution here: I use Quickload Mv predictions W/chronograped results to estimate the actual pressure when physical signs dictate safe pressure. When I approach the Mv that is predicted for a given safe chamber pressure W/O pressure signs, I stop there. W/Vv N550 that was about 2gr under the predicted powder charge in my VZ500 based commercial 98 action 8x57.. AS always, start low & work your way up W/chronographed results. Just like book published load data, every rifle is different. If you get me the FIRED case capacity in H2O grs & barrel length I can get you a better MV prediction to use W/a chronograph. Using actual case capacity QL has been uncanily close in MV predictions W/1 exception. That was in an 8mm-06 AI W/Norma 203. Even my reduced starting loads were HOT. Other than that 1 exception, QL has always been within a grain or 2 of Mv prediction & pressure sign indicaters.

Hello, QuickLoad doesn't work with RL-17. I am trying it now in .375H&H and will also reload friend's 8x57JS. With .375H&H, it predict much higher velocities and pressures. Please visit this forum: http://forums.accuratereloadin...2511043/m/2461051081 Jiri | |||

Wildcat Thanks for that. I am not using 76 grs of 4350 behind a 286 gr bullet. I can't get that much powder in my cases. However that is listed as the max load in the Nosler manuals # 5 and # 6. Always wondered about that load. | |||
|
| one of us |
Something isn't right here. Wildcat, I understand that Quickload is just an indicator. There are many other variables that can change the pressure and velocity. However something isn't adding up. The CIP pressure for the 9.3x64 is almost 64,000 psi.The 76 gr max load of IMR 4350 in two manuals is not a misprint. I can't see Nosler printing a load that developes more than 80,000psi. The COL listed in the Nosler manual is given as 3.370". They are using RWS cases and so am I. 76 grs of 4350 is listed as 113% load density same as you said. When you ran the Quickload program did you accidently put in 76 grs of RL17 instead of 76grs of IMR 4350?? to get the 80,000 + pressure | |||

2.950" is my current OAL. I am not sure what the max pressure is for the 6.5x284. Do you have a listing? | |||
|

This is what Quickload predicts (I measured water capacity of fired cases etc., so every value is fine tuned):  What you see is insane. Crazy pressure and velocity. But in reality it is about 2600 fps at the 2.5m from the muzzle with incredible low SD. Load is faster than Norma factory ammo but with lower recoil, bolt is very easy to open, nice primers etc => there is nothing like 73000PSI. Jiri | |||

Well, I went back & checked. There was an error, but not what you suggested. The 93 x 63 RWS is directly above the 9.3 x 64 Brenneke in the drop down menu. The case volume is 3gr less for the 9.3 x 63 so it did skew the pressure up some. I had inadvertantly used 9.3 x 63 data. Still, the estimated pressure for the 9.3 x 64 Brenneke is is not that much lower for the loads listed. The data for the 76gr IMR 4350 is 75370 @ 2735 fps @ the standard COAL of 3.370". As far s Nozler manual #4 & #5 cotaining misprints or false data? Both of my #4 & #5 manules list the 8X57 IS W/54gr IMR 4350 qas achieving 2700 fps W/a 200gr Patition. I have never been able to get much above 2600 FPS W that bullet & powder combo & Quickload agress W/my real worls findings. They seemed to have dropped that laod listing form their online load data. Nosler's data is not infalable. Another thing to consider is that perhaps their 9.3 X 64 data was achieved in a barrel W/a larger chamber bore than spec. ALL loading data should be approaved W/caution, be it boof published data or Quickload data. Besides, 113% load density is a bit high IMO. I regularly use LD up to 107%. I find it a bit far fetched to be able to get 113% load density & still be able to seat the bullet W/O case bulging or bullet migration after seating. Corrected predictions @ your 3.345" COAL: 70grs RL17 = 55870 PSI @ 2613 fps 76gr IMR 4350 = 77041 PSI @ 2746 fps GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

I don't have the latest release of QL but in my version I've found issues with Barnes TSX bullets. Their book loads generally show dangerous levels of pressure in QL. At least that was my experience with 338 Federal and 350 Rem mag. They may have corrected it in the latest version. | |||

I need to know what 140gr bullet you are using. It can drastically alter data. Quickload lists 59,465 PSI as MAP for the 6.6X 284 Norma. GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

Quickload is only a tool to guesstimate pressure/Mv. It is not a substitute for published data that has been tested W/pressure measuring gauges. But, published "book" data can not be taken as gospel in a given rifle as individual barrel specs can alter the results. I have found 1 instance where Quickload was far BELOW real world pressure results from the appearances of cases & bolt lift that I observed. For the most part, The data has been very close to real world results. GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

Does anyone have suggestion for using RL17 with a 270gr bullet in 375H&H? I work up loads for accuracy first and velocity is only a concern for knowing what to expect ballistics wise. I've currently worked up two loads using RL15. The first is using a 270gr A-Frame. I've gone past the manual max of 71.5gr of RL15, but the most accurate was at 71.5gr which gave a MV average of 2620fps. The second load is using a 270gr North Fork. I've taken that load up to 74gr of RL15, at this level I was getting just a slightly more resistive bolt lift. No signs on the brass, but again the bolt was just ever so slightly more sticky. No matter, the load gives one inch 3 shot groups from 72.8gr to 73.0gr of RL15. Average MV was right around 2685fps. I would happily hunt with this latter round. But if RL17 will give higher MV with equal accuracy why not give it a try? I gave RL17 a go with 300gr projectiles, but it was a short lived effort. I found a very accurate load using IMR 4350 that gives a MV of 2560fps with a 300gr A-Frame and so I quit there. So on the shelf sits nearly a full pound of RL17 looking for a purpose. It would seem reasonable to me that if 74gr of RL15 is still safe, that starting loads of RL17 at 73.5gr and working up from there would be a good starting point. There isn't any RL17 loads for the 375H&H listed on Alliant's website. But in comparing 300WM RL15 loads to RL17 you can put a significantly higher amount of RL17 in the case. Your thoughts? | |||

7MMNut: I am "researching it" now only with 300gr bullets (Speer African Grand Slam Solid and Swift A-Frame). What I found is that it begun to stabilize muzzle velicities at loads at over 100% filled case. That's for 300gr. I do not know that but I predict that it will NOT be good for lighter bullets (will not burn consistently), but it will be definitively good for heavier bullets. Jiri | |||

In my Pierce 6.5x47 Lapua running both 140 Partitions and Berger VLD's I'm getting 2860 and 2950 fps, respectively from a 26" 1:8 Broughton barrel. Both running .5 moa 5-shot groups. My little Pierce LOVES Varget and 125-130 gr bullets. Just killed a 3x4 mulie buck @ 500 yds yesterday, here in Montana, using the Barnes 127 gr LRX @ 2800 fps. Alan  | |||

I decided to try RL17 in an 8x57 a few days ago, but the case got full before i had any sort of reasonable velocity. I may have a slow lot of powder, as this has been my experiance with every caliber I have tried loading with this particular container. | |||

Varget predictions are about 40 fps below predicted & real world results for Vv N550. Varget has been very close to real world results in my 8mm-06 AI. If I can duplicate Vv N550 W/a powder that is 1/2 the price & readily available like RL17, I will be happy. I typically strive for compressed loads in the 102-107% LD range. I seem to get very consistant Standard Deviation results & good accuracy from lightly compressed loads. I use a drop tube & careful pouring techniques to acieve tight, consistant case filling. I think RL17 is worth a try in the 8X57. GOOGLE HOTLINK FIX FOR BLOCKED PHOTOBUCKET IMAGES https://chrome.google.com/webs...inkfix=1516144253810 | |||

RL-17 gives me 100 fps more MV than RL-15 using the 286gr NP in my 9.3 X 62. In my T3 (22.4" barrel)it takes 7 to 8 grains more to achieve that. At the same time the pressure appears less. I'll not give the details here, but you'll find them in my blogs of a few months ago.

I use Reloder 17 in my Sako 75 with the 270gn Woodleigh PP. Have tried up to 79.5gns which gave 2891 FPS. 77.3gns gave 2852 FPS and about MOA. I've settled on 75.5gns for 2739 FPS and a group of 0.575". Even 79.5 gns didn't seem to exhibit high pressure signs.

I'm useing R17 in my 284 Winchester long throated bolt gun 24" bbl. Shooting the 140 Nosler Accrabound @ just under an inch with 54.0 grains of R17. Chronographed the velocity at a five shot average of 3053 @ 47 degrees. I am going to try the same load with Nosler 140 TTSX next. Easy extraction & no flattened primers in my gun.

I think that R-17 is a little too slow for the 375H&H. It needs a little more capacity to bore to bring out the best. It works great in a 416 Rigby and 338WM. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

We have used the R-17 with 350gr bullets in the 375 H&H and 375 Ruger with excellent accuracy and velocity. | |||

But was it an optimum powder for normal weight bullets? I seem to remember the 375H&H preferring powders a little faster. With the 416 Rigby we learned that the "4350/R-17" group was about as slow as one could go with 350 grain bullets in 416Rigby. That was not true of course, for heavier bullets. The 350 grain bullets in .375 calibre are extra-heavy for calibre, and then a slower powder is necessary, which for the 375H&H would be the 4350/R-17" group. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

Nobody told this banteng that Reloder 17 won't work in the .375 with a 270gn Woodleigh. I'd have thought 2739 FPS with mild pressure and sub 3/4 MOA accuracy was reasonably close to optimum.

Nice animal and good load. Yes, 2739 with a 270 grain bullet in 375H&H sounds like a winner. I stand corrected and will think more in terms of R-17 than 4064 for the 375. +-+-+-+-+-+-+ "A well-rounded hunting battery might include: 500 AccRel Nyati, 416 Rigby or 416 Ruger, 375Ruger or 338WM, 308 or 270, 243, 223" -- Conserving creation, hunting the harvest. | |||

Be careful with that. It's certainly proven faster burning than H4350 in 3 cartridges I've tried it in.
