I have been shooting my Savage 12 LPV 300wsm for the past several weeks trying to see if I could consistently shoot 800-1000 yards without spending several thousand on a custom rifle. my shooting had improved and so have my loads but I am having a problem putting each group in the same spot. I am using winchester brass weighed trimmed and turned neck sized with 67.7 gr N560 210 vld's and cci mag primer. It shoots 6-8 in at 813yds sometimes a bit better but after a four shot group and check Target I sit down and shoot another group and it may be ten inches left and a bit high ..... or low or right... u get the point. Thought it was just me so I had a friend bring his rifle yesterday and shoot and almost the same results! He is shooting same gun but a vortex scope instead any thoughts? Wind was very light ... temp mat have changed some but not much I'm guessing I'm missing something major but I'm lost at this point, I've home thru so many different loads, seating depths, bullets, charges.... etc I did notice my chrono was 2991...2992...2989..2978...then dropped 30 to 40 fps on the next four or so and I don't know why they were all loaded exactly the same.
