I got 9mm loading fairly well down and having fun with it. I want to start loading .243 Winchester rounds and have gotten most of the components for it.
I measured the OAL for my Remington 700 to the rifling and I came up with a length TO the rifling of 2.747 using the Speer #1220 projectiles I am planning on loading with.
My question is that the MAXIMUM OAL as published is 2.710 which leaves a difference of .037 if I want to load to maximum length for best accuracy. To me, being a hobby machinist, that is quite a large difference and I am not sure about loading to the length. It looks like I will have no problem using that length in the magazine and it should fit fine but I am not sure about any other issues. It also seems as if the projectile will have a full seat on the neck of the cartridge at that length. It is a boat-tail bullet and the boat-tail starts right at the case neck transition.
Any help, advice or "your doing it wrong stupid" would be very much appreciated!!!
Thanks!!!
