For those interested, shot my 75.5 gr load today with R22 and Sierra 180 GK. Temp 38 and 2925 fps.... usually does 3000-3050 in warmer temps.
Shot 77 grs of R26 and did 3035 fps and 78 grs did 3125 fps. Could cover the 3 shot group of 78 grs R26 with a dime. Others grouped 3/4" +/- ... that's...
Same with H1000. Are many guys trying the new Endron IMR powders? Seems those go from 4350 range through Retumbo .... that covers a lot of ground/cartridges.
Scotty, thx for the feedback. I ve had at least one 300 WM in my safe for 47 years; yeah, I m old. Shot one of the 4831 s the first 20 years and R22 the last 25-27 years... all have performed great.
Mostly thought R26 might be worth a look since it's done so well in my Swede ( like wise for...
Desert Fox, you re right... no real need to change just like to experiment and gives me an excuse to shoot!
Currently using IMR4831, R22 and Retumbo ( along with R26) in a bunch of my rifles and see R26 as a potential candidate to replace with one powder. So far have seen good results to date.
That s really good velocity with that amt of powder. Did you work up any higher in R26 powder charge by chance? I m seeing data that goes to 78 grs or so with some 180 gr bullets. (Speer)
Haven't tried it in 243 or 270 yet... I d expect similar results.
Need to wait til it's more available before testing my cartridges... I don't have that much of it!
I ve had really good luck with velocity and accuracy of 75.5 grs of R22 with 180 gr bullets in numerous 300 WM s. Usually runs 3000-3050 fps and under an inch at 100 yds with 24" sporter barrel hunting rifles.
Looking for anyone's experience with R26 in 300 WM with same weight bullet. ( I...
Should anyone have a long action Vanguard McMillan Sako Classic Edge fill cut for sporter barrel that they re not using let me know. Color not extremely important.... I can repaint/modify.
Thx
Not a ton of 17 caliber shooters but wanted to get some input from those of you who do have a 17. I m interested in your seating depths vs the lands of your rifle.
History, my 17 Hornet has to jump a 20 grain bullet .100 since they re so short and in order to keep enough in the case for...
Not a temp stable powder but I worked up to 53 grs of IMR4831 ( look in Nosler manual; it's their accuracy charge with IMR4831 and max velocity also) with an 87 VMax and in my 24" Vanguard shot .750-.800" 3 shot groups. Guessing it's do well with 87 BTSP too.
I ll be watching this QL request also.
Pharm, I shoot a 162 AMax in my 24" Rem 700 and getting 2650 with 41 grs Varget and 2700 with 47 grs of H4350. These are both at or slightly above max so work up to a them if you attempt. I have an extended Wyatt Mag and load to 2.910 OAL. I m .025 off...
