I've been taking a few results from posts and trying to find a "mirror" powder on my QL.
What I've found in real life reloading is that QL "thinks" I4350 is hotter than it is...at least any of my lots.
What I've found by tracking some quoted velocities in several cartridges and using Alliants data is that RL17 seems to mirror I4350 guestimates for vel and pressure on Quickload.
I'm not saying that RE17 is a duplicate to I4350 in real life...just that it seems to be a mirror in performance to QL's guesses of I4350.
Anybody else using QL to try and forecast re17??

I'd like to know myself. I'm thinking about trying it in a 9.3x62 with 270 Speers.

I don't use QL and I think Alliant
may have overstated R-17 as to comparing it against IMR-4350. I'm sure in some rifles/caliber there may be gains. I've got a custom 270WSM with 58gr/IMR-4350 and 150gr bullet 3047fps with 58gr/R-17 same bullet @ 3024fps max load for IMR-4350 is 58.5gr, R-17 max load is 60grs.

In the 30-06 used less R-17 as compared to IMR-4350 and I got less velocity with R-17.

I'm going to try R-17 in some other calibers never know unless you try it.

Thanks Tom.

Kraky ----- I just started on RL-17 with .243 and .257 WSSM's. Only one session so far, I was impressed with speed and accuracy compared to W-760. Speed was less than IMR-7828SSC with same bullets. I have not tried it with my .270 WSM's, may do that today, weather permitting. First day impressions were good to excellent, more time will tell. I am most interested in accuracy with good speed, speed taking the back seat, if necessary. Good shooting.

I guess I should have mention that I chronograph after I get a good load don't want anyone thinking I'm just chasing velocity. I was impressed with the groups in my 30-06 but I have other loads that groups just as good or better but with higher velocity.


phurley5, could you post what your getting with the R-17 in the 243?

tom holland ----- Sure, don't have them in my head enough to quote, will get my charts and get back soon. Good shooting.

tom ----- I got my loading information from the Allient site. These are my top loads from a Browning A-Bolt .243 WSSM with Ziess 4.5 X 14 Conquest. Nosler partition blem, 210M primer, 42 gr. RL-17, Temp 80 degrees, two three shot groups, each approx. 1 inch, speeds 3164 and 3178 fps respectfully. ----- Second rifle a Browning A-Bolt 25 WSSM with Zeiss 4.5 X 14 Conquest. Bullet a 100 gr. Nosler Ballistic Tip blem, 210M primer, 47.5 gr. RL-17, Temp 80 degrees, two three shot groups, both 1 inch but both put two nearly in one hole and the other 1 inch from them (probably the shooter not the rifle) speeds 3197 and 3240 fps respectfully. I will be trying the RL-17 on my two .270 WSM rifles in the near future. I use an Oehler 35-P chronograph. Hope this helps. Good shooting.

My quickload results differ considerably from what folks are "claiming" they are getting within "safe parameters" in real life.

Pop,
My experience with Quickload is that two settings matter a lot in regards to calculated chamber pressure and actual results. One is the seating depth or OAL and the other is the H20 capacity of the brass as compared to the default setting.

For example, AA2230 powder max of 44.8gr for a 200gr bullet is in Accurate's reloading manual at 60,000 psi measured. In Quickload with defaults it shows over 68,000psi. I measured 5 empty cases with the primer in and my H20 capacity is 58.6gr versus the default Quickload for 338 Federal of 57.5gr. When I change to the correct H20 amount it lowers the Quickload chamber pressure by over 3000psi. Now also Accurate's reloading manual uses 2.800 for OAL and I load to 2.919. That lowers the chamber pressure in Quickload to ~56,500psi. So you can see that by having the correct OAL/Seating depth and H20 there is a 12,000psi difference in the Quickload calculations. When I shot them in my rifle using a couple of grains over the max of the Accurate reloading manual (but safe from Quickload for my OAL and brass capacity) I saw no pressure signs at all in my rifle. I did work up, and used the higher max amounts based on other reloading manuals like Barnes.

I also had to change the weighting factor from 0.50 to 0.33 for 338 federal to more accurately match real world results in various reloading manuals. So my experience with Quickload is that settings matter, and requires a few tweaks to be right on.

I totally agree with you! Again it is just a guide not a panacea.

I noticed the same with most shooters shooting 200 grain slugs from their 300 RUMs at 3250 fps and saying these are safe loads.
Q/L says that there is no way you can do that safely. Who knows?

My rums maxed out (using visual signs and experience) at about 3100 fps or so.
