What about burn rate of powders?
I shoot a .300 win mag. 150, 165, 168 and 180gr. bullet. I've played around with 4895, IMR4350, XMR3100, and H1000. I've had good luck with 4350, but thinking of revisiting some of my old powders or looking into something new. What effect will burn rate have on bullet performance. Right now my loading 168gr. HPBT with 74.2 ga IMR4350. I shoot a 700 BDL and am looking to improve 300yd plus shooting.
