dorg Posted March 2, 2017 Report Share Posted March 2, 2017 As above I'm getting about 3100 fps in a wsm, just wondered how much faster they could be pushed before they blow up. I fancy scratching a 7mm rum itch. Link to comment Share on other sites More sharing options...
Elwood Posted March 3, 2017 Report Share Posted March 3, 2017 I have read that people are pushing them at 3300 + fps in the 28 Nosler. Link to comment Share on other sites More sharing options...
The Gun Pimp Posted March 3, 2017 Report Share Posted March 3, 2017 Mine used to blow the odd one around 3100 but that's ten years ago - maybe jackets are thicker now. Link to comment Share on other sites More sharing options...
OSOK Posted March 3, 2017 Report Share Posted March 3, 2017 I've had them around 3,250 ft/sec using a 7x68 Imp without any problems but then testing in a tunnel your probably not going to get issues . I backed it off to 3,150 ft/sec as group and spreads worked well there . I've never had a 180g Berger blow on me even when i ran 34 inch barrel's with the WSM as it's not just about the velocity it's also about the time it's in the barrel .
