the 231 uses volumes like the Unique, 6-8 grs. however the 296 is like 17-19 grs. thats a big difference in volume not to mention that the 297 could cost almost 3 times as much per shell for the powder.
Was just wondering if anybody had used the 296 does that require mag primers, if so don't want to go there.
Opinions please.
