To make a very long story short, I'm shooting a 300 win mag. Browning a bolt ll action,Christensen24" barrel, 1-10 twist,custom carbon fiber stock bedded.Leopold vx5 3-15x56.weighs in at 8lbs.
I've tried many different bullets geared towards long range capabilities,including 190 gr ablr, 180 ab.200 ab.175 lrx,200lrx, 180 sst, and 200 gr eld-x. I could always get it to shoot decent in the 1 to1 1/2 moa range no matter what ,but that wasn't gonna cut it for a rifle I have quite a lot money invested into. I did get the 200 gr eld-x to shoot very good at times but had major inconsistencies. (See my other posts warning about hornady eld-x)At this point I'm around 600-700 rounds through this barrel.
Steve, from hammer bullets suggested I give their bullets a try.I ordered a box of hammer hunter 181 gr.and as Steve's recommendations, Imr 7828ssc, seated the bullets as long as the mag box would allow,which ended up being .120 jump. I loaded one round at a time watching velocity and looking for pressure signs.77 gr. Put me at 3100 fps. I called that good with no pressure signs. I loaded up 3 at 77gr, went out to 410 yd.and it shot .60 moa first group. Velocities were, 3097,3100,3100. I believe it shoots even better than that but that's the best I can do with only 15x scope. Its consistant now, and I've shot multiple 1/2 moa groups since. I believe its true about these bullets not being sensitive to seating depth,and everything that the website and Steve has said has been true in my case. I recommend you guys give these a try ,especially if you have a finicky rifle. I can't wait to try them out on game!
Thank you Steve for an awesome USA made product.
