I have been reloading Lapua 250gr Scenar in virgin Lapua brass for my .338LM. I use a Hornady OAL Case Gauge with modified case to messure my head space. I use the Hornady Comparator to messure the bullet and modieied case, and get a messurement of 3.969". I would reduce this messurement and reload at 3.959" COAL.
I have since ran out of the Lapua Scenars and am starting to load test for 250gr SMK. I use the same method to get my COAL, but now the cartridge is too long for my magazine. I know I should have a COAL that is as close to magazine length, but how will this effect accuracy?
Rifle: Sako TRG 42 .338LM
Head Space: 3.992
Max Mag Length: 3.960"
Difference: 0.032"
Thanks,
Hugo
