Hello guys, I was hopping someone could advise me. I have encounters a problem while trying to develop a load for my Winchester mod 70 300 win mag. I'm pretty new to reloading but I have done a fair amount of research. I have asked a few friend for help regarding the distance my bullet needs to jump before it hits the lands but none are able to help me. I hope someone here can help me, I'm questioning my rifle at this stage. All measurement are in inches. The brass I am using are hornady, trimmed and measured to 2,620. I'm loading nosler balisstic tip 180gr. If I seat the bullet to just touch the lands my over all length from base of the case to the tip of the bullet is 3,530. At this length the loaded round will not fit in the magazine. To fit in the magazine the over all length will need to be 3,390. My concern is the the jump the bullet will need to make before it hits the lands is quite a big one. So is this acceptable? If not is it possible that there is something wrong with my rifle? Please forgive me if this is a silly question. I can't see how a long jump like that is going to give me good accuracy. Any advise will be greatly appreciated.
