I have searched the net and can't find anyone that is shooting the 150 gn AB and the new imr 4451 powder . I found someone that is shootin the NP 150 start load was like 55 to max of 60 gn . I didn't know if that data would swap over so I figured I better ask to be safe .
Thanks
Butch
Rl22 and 165s gameking hpbt
Is giving me 3400 fps at .3gn over max and .701 three shot group @100. . I am longer that book length and .020 off L&G ... rl25 and the 180s about the same as you avg of 3075 with a .085 in group at 100
Cant find any data on imr4831 for a 95gn Hornady sst for a 243 .
From reading on the net looks like folks are 43 n 44 gn but I can't find any real data .. this is for my daughter so I need to be sure..
Thanks
I'm keepin it as a go to load but working on a 165gn rl22 load now .. hoping to pick the speed up close to the 3300 fps .. I got 3290 with the 165 AB and rl22 hope the gamekings give close to that speed and a under 1moa group
Bad news is the chrono speed on the 165gn sierra gameking is only 3070fps with the 4831 ..
good news is the rl25 and the 180 ballistic tip shot a .7 group at 3050fps ... the 165 accubond with the rl22 shot 3290 fps ... I have a ladder loaded with the 165 sierra gameking hpbt and rl22 and see...
Cut a .516 group today with 74gn imr4831
one thing also helped was without the polymer tip I can load touching the L&G. . I'm not I'm .015 off L&G
where the mag limited me to .051 with the BT
thanks so much for the help yall
