I would like to build a short action caliber just for target and maybe a canyon rifle for coues deer. I'm pretty open to caliber. I was thinking 6 creed, 6.5 creed, or even a 243 or .243 ai. Looking to go heavy barrel sendero or MTU but I'm pretty open. Looking for some input on a good combo barrel twist contour. I used to have a .243 and I enjoyed it. I reload a 6.5 creed for my son all my other rifles are long action. I dont need to get too exotic I just want a good shooter. Thoughts.
