Been poking around here for a while and have decided to start a rifle build and learn to develop loads in the process. Just getting started and was wondering what tips yall had. My plan is to start as a very adequate rifle and load for deer and then move to longer distances in the spring. The rifle is a factory 111 barrelled action with a B&C Medalist sporter on the way. I have a LOT of once fired brass and a RCBS press. What dies? Neck sizing vs. FL? I have been very happy with 130 Hornady SST for my .270, any comments on 150-180 SST for .300? Any help is greatly appreciated and I'll be happy to provide any other info needed.
