I ordered some Vollmer Precision Bullets, 180 gr. with heavy jackets for .358 Win velocities, semi spire points.

These are hand made, custom bullets, could be interesting.

Another thing about Vollmer, they'll make bullets for odd calibers, have a kit for slugging a bore.

I went with .358". I looked at which bullets shot best in this gun. Pistol bullets, like the 170 Gold Dot and 180 XTP measured .357", 225 NPT was .3575", the Speer 180 FN was .358+. 175 and 200 FTX's were .358, as was the 180 TTSX. So, there was no pattern there, other than it likes light bullets and fast powder. The .357 pistol bullets were about as accuate as any, the slightly larger Speer 180 FN was also pretty accurate.
