[QUOTE="bscman, post: 2843854, member: 126797"] Bullet seating depth will absolutely have an effect on accuracy, however at 65yds you're talking accuracy differences in the tenths of an inch, not inches. No surprise you still hit the pest. The more important issue might be the pressure spike created when you have a bullet pushed that far back into the case...you lost a lot of volume and increased the pressure substantially, no doubt. I know I'm 9mm 0.030" too deep can double the pressure with some powders. As for HMR neck splitting, it's well documented all over the Internet usually stemming from brittle brass after the forming process. Don't worry much about it, just keep the chamber clean. I've had hundreds of split necks in my marlin 917 and never had an issue. More often than not, I don't even see a flier on the paper. [/QUOTE]
