Anyone have any pet loads for 20 BR with 40 and 50 gr bullets
Go to 6mmbr.com. They have a 20 caliber page that has some good 20 BR load info.
Bit late I know but N150 with either a 205 or a BR4 is very accurate.
For the 50s I am running 29.5gr for about 3500fps in a 27" Bartlien. N160 and N550 are no better, have to use more of both fr same velocity.
Above 30.0gr the 205s are starting to crater. 32.0 or so gets it to 3800 but with bad cratereing and some web expansion.
39ge SBKs the optimum load seems to be 28.5gr N150, about 3600 but not yet chronoed. Shoots .3s and devasating on arrival, far more so that the Berger 50 MEFs
