Hey guys,
I neck size for my only bolt action rifle (7mm-08) with the Lee collet die, so that's all I really know.
But I recently loaded cases purchased new, which I neck sized and uniformed the primer pocket, and then loaded same as my fire formed brass.
I loaded the 140 gr. SGK BTSP in the fire formed brass
and the 139 gr. Hornady BTSP in the new brass.
Both were loaded with the same charge of IMR4350.
I was surprised to see that the SGK loads gave much better results.
I would have figured these two bullets were pretty much the same, so I'm wondering if the improvement was do to the brass being fire formed (I can definitely tell the difference when closing the bolt).
Inquiring minds want to know
