I'm about as new to reloading as it gets and I have an issue that I think needs to be addressed before I decide to shoot the rounds that I just made.
I'm reloading a .350 Remington Mag that I'm going to be shooting out of a Ruger M77 MKII with 225 Grain Barnes TSX and IMR 4320. I wanted to start out light so I only loaded it with 55 grains of powder (very conservative according to my manual).
The problem I'm having is that my end result is exactly 0.1 inch longer than what my manual and dies state should be the maximum overall length of 2.8 inches. After making a few rounds and having them all come out to 2.9 inches, I started doing some research online and came across a few articles that talked about how the Barnes .35 caliber bullets were designed to shoot in the longer action of the 35 Whelen and not the short action of my rifle (the bullet itself is pretty long).
The mag well on my rilfe is actually a little longer than on the Remington rifles and my rifle cycled all ten of the rounds I made with no issues at all. Is this something I should be concerned about?
Also, the case length stated in my reloading manual is actually shorter than the cases I'm using on unfired factory ammunition. With these longer bullets should I be worried about overpressuring the load if I actually trim the cases down to what the manual says I should? Like I said I'm pretty green to reloading so any help would be greatly appreciated.
