Got my first long range hunting rifle from Snowy Mountain Rifles a few months ago and simply can't get her to group like I know she should. Have about 100 rounds down the barrel now. Rifle info 1:10 Twist 28" Remington Varmint Contour Barrel SMR 416 muzzle break NXS 5.5-22 Manners MCS-TA TS-100 SS Series in 338 Lapua. Hand Load Info. 300gr Sierra Matchkings 89Gr(2700fps) & 93GR (2800fps) loads of Retumbo Tried 4 different lengths from 3.950 up to 3.979 Laupa brass Rem 9 1/2 Mag primers 300gr Berger Hybrid OTMs 93gr Retumbo (2800fps) Tried 3 different lengths, kissing the lands, slightly off the lands, and magazine length. Laupa brass Rem 9 1/2 Mag primers Have done a ladder test at 200 yards that didn't work very well, but my max load with a heavy bolt lift is 94gr with the the SMKs. Even with all the variations I have tried the rifle shoots extremely consistently, just not very good groups. Best group I think I have had at 200 yards is about 1 1/2". I'm kinda at a loss now to get these groups tighter. I have been following this guide pretty closely for the loading technique. Hand Loading for Long Range 1: Brass Prep Perhaps another powder, bullet? With the fired brass length I am still about .20 off of what my max headspace measurement is. My last 2 reloads I have just selected my shortest round and trimmed to its length for consistency. Perhaps I should just not trim until I get up to that max length? Forgot to add that on my second reloads on this new Lapua brass the case is slightly stiff when chambered even though I knocked the neck back. Id be extremely grateful for any suggestions you guys may have!
