I have been using 45acp 200gr SWC's for a long time in my 1911 but they don't feed so well in my Sig 320 so I bought some 230gr RN's. I loaded some 230gr RN's with 4.8 grains of 231. My 200gr SWC's are also loaded with 4.8 grains of 231. When I went to shoot my Sig 320 today, the 200gr SWC's loaded with 4.8gr of 231 were a milder load than 4.8gr of 230gr RN (same OAL). I was a little surprised. I would have expected 200gr SWC's to be a hotter load than 230gr using the same amount of powder and the same OAL since the SWC's are lighter.
How many grains of 231 would you expect to use in 230gr RN's to have similar recoil to 4.8gr 231 in 200gr SWC's, OAL being about the same
