anybody shooting WC872 in a 7mm Allen?
just looking for a starting point. Kirby says that the 4 groove 1-9 won't take the pressures like the 3 groove so start with upper mid level loads for a 7 rum, ok, this according to AA's 8700 data is 95 gr. on testing my 7STW with wc872 and 160 nosler accubonds, I maxed out at 95 grains. so is this where I should start or what? that just seems like a low charge for the allen case.
