I'm asking this for a friend.
He has a Remington 700 bull barrel 22-250rem that shoots 50gr Hornady v max very well. He trimmed Hornady brass with a lee pilot, lyman ez trim shell/case holder and it would trim them at 1.911. His start load was 36gr of H380 to 39.3, OAL of 2.342 which is factory spec. This load shot 3 shots one hole, 1 flier and one to dirty the barrel. He trimmed the cases with an RCBS lathe to 1.902 and did not adjust the seat depth on the die and when we measured a bullet OAL it was 2.352.
Last night we measured all the cases out to 1.902, adjusted the die to the OAL of a factory round and he shot them today and they are shotgunning all over the paper. We also tried using the Hornady OAL tool with the modified case and it was giving us results way over the book max OAL.
Any thoughts from you guys what's going on here? I figured if the factory round shot well then that seat depth would give him at least something decent but we are talking softball and larger groups.
