Question is I have no experience with the 243 round or where to start with bullets and powders. This barrel from what I understand is a 1:9.5 twist. Midway and MidSouth both have some 60+ gr, 87/90gr and some 105 and 108gr weights in stock. Not sure how well the 60 gr verities or the heavies will work in this barrel. Powders I have on hand to work with are BL-C2, TAC, Benchmark and 2460. any of these any good in 243 or should I look for something else? Plan is to eventually replace this barrel with a 6br Norma So lets hear your thoughts on a starting point. Just components, not loads.
