Reloading data for this caliber is scarce...but 21 grains of H110 and a 158 xtp flatpoint will shoot MOA at 100 yards. 20 grains of Lil Gun will get you 2.0 inches. From an 18 inch barrel velocity is 2215 with H110 and 2170 with Lil Gun.

I have been working up 360 DW loads for my MGM 357 Maximum Contender Barrel. I have been hot roding the brass pretty hard. I have been seating 180 XTP's only .20 in the case and winding them up, just seeing what is possible using 360 DW brass. Some of the Starline cases are getting to around 10 pretty warm reloads. No loose primer pockets, no split cases. I am very impressed with the 360 DW brass. Now I am ready for some QUALITY Starline 357 Maximum Brass. :)
