Hey guys, I'm looking to get a custom barrel made from Match Grade Machine for my little T/C Contender in a caliber that a very young, small shooter could use for their first deer season but also something that's not too loud and recoiling that they can do a lot of "fun"shooting throughout the year to help them become more proficient with shot placement. I'm thinking I'll probably have the barrel cut down to 16"-18" so that the overall length and balance will fit a small size shooter. MGM has a huge list of calibers available and I do reload, so it doesn't need to be an "off the shelf" caliber. I just need to be able to get or make brass reasonably easy for whatever caliber. Any advice?
