I'm fairly new to reloading so please bear with me. My first hunting load I've loaded up for my 280 is 162g SST's. I'm .03 off the lands with my load. The problem is that my magazine in my Ruger M77 wont' take it because it's too long. Obviously I will seat it more so it will fit in the magazine, I'm not going to make a single shooter out of it. It is my hunting rifle. I'm wondering what impact moving my bullet farther away from the lands will have. Of course I won't know till I go shoot them, but we're talking thousands...I don't forsee this as being too much of an issue as there is no way all the factory loads can be exactly a perfect distance from every model rifle they are shot int...but we're reloading right, we need accurancy! The Mark II has more room in their magazine, they must have had an epiphany. I'm sure it's the higher BC, ballistic tip, and slimmer bullet that is creating this issue, as the fatter speers I used to use had no problem. Thanks for any insight or experience you can give me. I was looking for an actual number for this magazine length somewhere for this rifle, but am unable to find it. I'll just keep seating them deeper till they fit and see what I come up with.
