I bought a box of the Barnes factory rounds. The couple groups I shot were about 1.25” in my Tikka. The same rifle will shoot well under an inch with 147 gr Hornadys and 139 Scenars. The one doe I shot behind the shoulder with a 127 LRX ran a little ways, but I have had them run a little ways with the same shot from a 300 RUM and a 338 Lapua.
I will share it, but you need to do your own load work up as this load is HOT HOT HOT !!! I started load development for this rifle and went over published max load with no pressure signs. I was getting better and better accuracy the faster I pushed them. End result was 1/2 moa for about 400 rounds then they opened up to about 1 moa over next 200 rounds. I had
Yup that's a pretty hot load! I was thinking that I would start with IMR 4350. I'm pretty familiar with that powder plus I have a few pounds of it. Something I liked about the lrx is that they seem to really like the velocity up around 3000.
Anecdotally, the interwebs seems to think it is 1600fps. Would be interested to see what Barnes says. I’d also think that would be subject to slight change if you shoot something hard— a scapula or big rib— as opposed to soft lung tissue.
Sounds like a good friend to have!
Yep, always had good luck at the recommended .050 off
Exactly the same process. I have one at .120 and one at .050.
Yes, you're definitely going to want to tinker with seating depth on these. I usually do a ladder test to find a generally suitable powder charge, then perform Barnes' recommend seating depth test:
