Used to have a 218 mashburn contender. The only bullet it liked was the 45 gr speer. I'd have to check my notes for loads. Once I did find the load it liked, I could fire a box full at the head of the 150 yd turkey silhouette and never miss.

One of these days I'll get an xp-100 221 fireball. I find the slightly larger case much easier to manipulate on the press and more friendly with loads.
