A 228-1R resembles 230 FMJ not at all, and rounds with both bullets loaded to the same approximate 1.262- 1.265” which duplicates factory 230 FMJ will result in the 228-1R not chambering fully even in barrels that have some throat.
Said by a guy who has loaded both type bullets and casts the 228-1R. That OAL is a problem when confusing the two bullets is a well settled issue and not open to doubt.
