Do I have a problem? Here's what I did.
I'm new to reloading and this is my first load.
Reloading for the 270 rifle. Using a Hornady 140gr boatail soft point (BTSP) Interlock. Small powder charge at 42gr of IMR 4064. Book says C.O.A.L at 3.280". My cartridge is a Winchester.
I set mine at 3.107. A difference of .173" shorter O.A.L. The bullet is seated just past the ribbing and, to me, looks a little too deep.
I came up with this length by marking the cleaning rod with the bolt closed and again with the bullet in the barrel, measured the distance and then compare it to a factory Remington 130gr soft point and they are the same. Later, I measured a Winchester 150gr Power-Point S.P. (with the white tip), and it measures at 3.25".
I'm concerned about the jump space and/or excess pressure caused by less air in the cartridge. Am I over concerned?
