Hi Lads.
243 hornady 75g v-max heads, done the powder weight testing arrived at 43.5 gn of Ramshot big game.
With a bullet seating depth of 2.640 im getting two shots within 1/2" with the third at 1 1/4" that is random -------suppose this needs more work ?
From 2.640 - 2.745 which is around the maximum length i can go while still keeping 6mm in the case neck there would be 22 setting at 5 thou, i dont fancy doing all them shots, can anyone suggest any ways to reduce this, ie with the 2.640 seating depth doing 1 1/4" group, does this suggest it just need 5-10 thou either side of this ----or doesn’t it work that way ? -------am i better starting at 2.745 and reducing by 5 thou until i hopefully get there.

Thanks for your help Dave (warbucks)
