Dummy Cartridge
Ok. I just got my 30" Heavy Palma PacNor .284 1:9 twist barrel in and plan to take it to my smith next week. I'm getting it chambered to a 7mm WSM but have to make my dummy round for him to chamber it to. I'm not doing a tight neck or anything so that doesn't have to be discussed. My question is what needs to be considered when creating the dummy round? How far out do I need to seat the 175 gr. Sierra MKs? Thanks in advance.
