Just had a new tube put on mine . Been looking at data & QL . In the past with 165 or 180gr J bullets 4350 / W760/H414 / RL 19 got first nod , 180's 4831 or RL22 if no like 4350 . 24" barrel 2700fps with a 180 , 2800 with a 165 was possible . Numbers some of the new stuff show has me intrigued . Of course we've all seen published numbers that were removed from the actual . Has anyone used any of the following :
Norma URP or MRP
RS Big Game or Hunter
IMR 4955
Superformance
StaBall 6.5
RL 16 or 17
Any pressure kinks , need for magnum primers , any other characteristics you noted etc . ?
