Re: Anybody use Speer .243 cal 85 gr. BTSP?
I shoot them out of my 6mm.....5/8 moa out of a throat that has seen better days
46.5 gns IMR 4831, Fed 210 primers, oal 2.820
they are very accurate...but they do leave an exit hole, but it's not near as bad as I get out of my 25-06 and 115 berger vld
not sure if any of this helps...mine being a 6mm an all
