I got involved in a trade and ended up with a Mod 11 trophy hunter in 204R. I got the gun with the the expectation of converting to 17 fireball. However, before I got the funds to do the conversion I decided to try out the 204R. Boy what a pleasant surprise The gun shoots so well that I am not going to convert it. The Message - Never shoot your donor rifle. So far I have found the Hornady 32 gr Vmax in their super performance line is the most acccurate. I will be getting supplies for reloading together. What amazes me is that if you do a search on what powders seem best. there is no outstanding best everybody has a different favorite. from 4198 up through Rl 15 seems to work.
