Have used 200 grregular AB in my 300 WM and shot 3/4" without much fuss ... unless you re shooting beyond 600 yds or so the std 200 AB at 3000 +/- fps from that 300 WB will be awesome.
Seems like many folks have had tough luck trying to get LRAB s to shoot. Because of that I ve not fooled with...
At 59 degrees and 4000' elevation should be supersonic to 1400-1500 yd range; lots of performance from 42 grs of powder.
When my 22-250 AI is shot out, I m thinking a 22 Creed for easy brass, dies, etc as far as a replacement. I just wonder if an 8 twist will work up to 88-90 grain bullets...
Shot 100 s of 75 VMaxes with IMR4831 in my VLS. It was easy 1/2 MOA and 3400-3425 fps. I loaded 48 grs which is just slightly more than QL prediction. It was a stout load but bolt opened well and Primer pockets stayed tight.
Real nasty on rockchucks and coyotes !
Picked up some 22 caliber 40 gr plastic tips from Midway a month or two ago to get ready for Sage rats and they re a flat base ( thus I believe Nosler and not Hornady) and they ve got 'gray plastic tips' on them too!!
Threw me a curve when I first in-boxed them ... lol
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
