The chamber walls on a 32 J frame are thicker than on a 38/357 J frame. S&W has offered J frames chambered for 327 Federal Magnum, which has a maximum pressure of something like 45,000 CUP, which I believe is the same as for 357 Magnum. So, same pressure limit, with thicker walls in the 32 caliber cylinder. There shouldn't be ANY problem for a 32 H&R Magnum round, which has a maximum pressure spec of 21,000 CUP.
