Hi Guys Im just starting to work a load for my new Sako75 in 7.08.I have Nosler Partition 140gr Federal L.R.primers and a fresh tub of R.L.19. There is not a lot of information on this powder where im looking. What Ive come up with so far is starting at 47grs.Some input would be welcome from you folks.Thanks.jc

John I looked over my data on this round and didnt have very good results with RL19. It Did work for the heavier bullets though.
for 139/140gr bullets.. 46gr min and 52+ grains compressed as a max.
My best results were from imr 4895 and imr 4350.
139gr bullets.
imr 4350 gave the best accuracy. around 2700f/s.
Dave

I think you would be better off using RL-15 or Varget. The new RL-17 might also work.

My experience with 7-08 is mainly using RL15 - 40.5 Gns over a Federal GM210M primer with 140 Gn anything Nosler gives 2835 fps and less than MOA on paper. Kills fallow and roe DRT. BTW, I use Norma brass, and note that this load is good for my rifle/chamber, usual disclaimers apply for anyone else's rifle. Work up the load to suit your own setup.

This load came out of Nosler Book 6, and it worked from the outset, just fine tuned the COAL to increase accuracy.

Good luck with yours.

I'm currently shooting 140 grain Nosler Partitions in front of RL-15.

Here is a bit more information for you using 140 grain bullets and multiple powders.

Thank you Gents for the quick replies. Looks like I have the wrong powder.
graybird; gave me a link with similar information that I have. I'll make some bullets for the range tomorrow and see how it shoots through the chrono. If no good I,ll pass it on as I only load for the one rifle.
I ran out of my usual powder H4895 that gave great results for my old CZ.243 but was'nt cutting the mustard with the 7.08.jc

John, RL19 might be a little slow for the 7mnm-08, but it is certainly usable. You could achieve respectable velocities, (but not top velocities) with compressed loads. The good news is it would be pretty hard load enough RL19 with the 140 partition to create any pressure issues.

The other powders mentioned above would all be good choices. I might also add W760, Ramshot BigGame, and BL(c)2 to that list.

Antelope Sniper. Thanks for that,Its an ill wind that blows nobody good. I,ll post what I find tomorrow.jc

RL-19 is a tad to slow, the slowest i have used is 4350 or H414, but my choice of powders are IMR 4064 or RL-15

After many years I only run Varget in my 708

43 grns under a 140 grn Accubond

I have been shooting 708 since 1982 and have tried a lot of different powders and Varget has proven to be the perfect powder for me in the 708. Others at the range really like Varget in their 308s as well.

Thanks Gents, as usual good information from you all on A.R.jc

Antelope Sniper. See what you mean, loaded 47,48,49, and the 50grns filled to the neck.jc

I've worked up loads for several 7mm-08's....one XP-100, two Savage Strikers, two Encore barrels, one Rem. Mdl. 700 and my most recent Savage Mdl. 14 Classic.

With bullets form 120 gr. to 140 gr. they all have liked Varget extremely well......for the best grouping they all wanted the loads to be at or towards to upper end of listed max.

Ike

John QL shows 50 grains as a max load, 11% compressed, and a velocity of about 2900 out of a 24" barrel.

If you worked up carefully, I wouldn't be suprised if you found a decent load with the RL-19.

Considering powder prices in Scotland, unless I had one of the others mentioned above on the shelf, I'd try the RL-19.

Antelope Sniper.
Thank you for that.Yes £44.00 per Lb.Not quite as expensive as gold (yet)

This is what l got at the range.
R.L.19; 48grn 2742-40 49grn 2847-56 clover leaf at 50yds Short Range but ok for testing.
Unfortunatly I messed up with the 50grn but it looks like it wont be far off your calculations.

Out of interest I checked the wee drop of H4895 I had left.
4 bullets x 38grn H4895.
2778.oo 2781.47 2783.39 2787.88 clover leaf at 50yds.
Yes the R.L.19 will do for the time being untill I get the faster powder.Very much appreciate the help and the chart is excellent .My barrel is 22" btw.jc

Thank you for the info Ike and everyone. Varget seems to get a lot of recommendations from the guys on A.R.jc

John
My favourite load with the 140gr Sierra SBT in my 7mm-08 is 47.0grs AR2209 (aka H4350) for 2900fps MV.

The same 47.0gr charge of Nobels No.0 powder produces same velocity and accuracy. I see you are in Scotland so you may be able to locate some Nobel powder which I have always found gave consistent results with good velocity.

Thanks eagle27,The (H4350)is on the list. hivelosity flagged it up earlier on the thread,Dave gave me good info a while back for my .243. Anyway greetings to New Zealand from the old country. Almost made it to Hamilton getting on for forty years ago. My how time passes. jc

Hi John,

A quick suggestion if I may mate, any cartridge that works well with H4350 also tends to do well with Reloder 17 if you've got some lying about.

I've switched from the former to the latter, netting about 100fps in the process.

Just another idea mate.

There are 2 threads running together on the same subject!

I use Varget mostly and a bit of N150 or H4350. I prefer 150 gr bulklets to 140gr & drive them at aound 2750 fps or a bit more. Accuracy is excelent - less than 1".

Hi Ghubert, Im kind of between a rock and a hard place with this due to all the good infomation here on A.R.
The QL info supplied by Antelope Sniper and the chrono readings I got yesterday (see above) has me thinking that by working up the H4895 ive been using,may just give me the desired result.
The H4895 gave me poor groupings at first but seems to have improved now that Ive put a 100 shots through the barrel with a cleaning regime. Unless,that is, the range chrono is giving me wrong readings, I figure Ive a couple of grns still to go to max. It works out about 10grns less than the R.L. per round.
Are there other considerations to take account of? jc

Naki, Thanks, yes he can get good info right here.jc

usually the higher loading density will give better accuracy.
don't give up on that rl-19 powder just yet.
work up a bit higher and try a hotter primer.
