so my swede is now surpassing all my expectations... 26" 1-8 twist mcgowan shooting 140 amax @ 3000 with 47 gr H4350 COAL 3.132 (.01 off lands) with no pressure signs. Shot 6 different 3 shot groups this week, the smallest being .38" and the largest being .58".

I chose this caliber to be my long range high volume steel/comp gun

QUESTION:
since its pushing a 140 in the 6.5 x 284 territory is it going to burn the throat up after 1000 rounds ? even with only 47 grains of powder?
Thanks
