sorry. at that velocity erosion's gonna eat your barrel alive, slow them down, there's no reason to be going that fast.

Lot of powder volume + small hole in barrel = big time throat erosion.

Excess case trimming or trimming too short helps hurry this along.

The chronograph is essential to LR success for someone hand-loading. Without one you might as well be shooting blindfolded.
