I have a new Winchester 92 (Miroku) in .357 magnum that is very difficult to load. My reloads (158gr SWC) are almost impossible to load thru the loading gate. I made up some dummy rds with 148 gr LRN and they were a little easier. Is this a common problem with the new 92s? I can always make up some new ammo with different bullets. What works best: round nose, round nose flat point or truncated cone? Is this something a local smith could resolve? I have an older '94 in 44mag and have never had a problem with that rifle.
