Re: Sierra 6mm 85 gr HPBT
Just a side note with the Sierra 85 gr HPBTs, I shoot 44.5 gr H414 with those bullets and get 3204 fps out of my Sako 243 Win. The same charge with NPs gives me 3422 fps. I tried other powders and seating depths, but I could never get the velocity up to where I wanted it to be.
I am now playing with some 90 gr Scenars, Bergers and shortly some NBTs. I am not saying the bullets will not work, but I have not had as good a luck with those particular bullets as I have other makes and models. If you have them, shoot them; however, you will need to avoid the shoulder bustin shots. jm2c
