I had TClaunch rechamber an old Krieger .236 4 groove 8 twist 6 BRDX bbl to 243 Win with a throat long enough to seat the 105 class bullets with none of the fat part of the bullet below the neck shoulder junction,,over all length with the 105 Scenar seated .020 off the lands is 2.885,,
when rechambering he cut the tennon off and started over so the bbl is now around 27.2 inches long,,
I started loading one round at a time at 46 grs RL26 and WW WLRM primers,at 48 grs I got slightly flattened primers and at 49 grs they were pretty flat but still no heavy bolt lift,,50 grs is too much and I erased the eading of that shot off the magnetospeed screen just so yall wont think I am completely crazy,,
the readings on the screen are for
46
47
48
49 grs of RL26 and 105 Lapua Scenars ,,one shot at each charge,,
I went back and loaded 5 rds at 47 and 47.5 and shot for group at 100 yards without chrono attached to bbl to get a good zero and idea of accuracy at these speeds,,the 47.5 gr load was .385 inch 5 shots at 100 yards,,
gonna try that at 600 now and see how it goes,,seems a 105 at 3300++ would be a lazer beam,,but gonna shoot it some and see how everything holds together,,
wish me luck as I am sure it wont last long,,LOL
