I just got back from the range shooting my 6" GP100. If I am reading the cases right, the bottom row all show signs of excessive pressure, yet I am under the start charge for 296 with a 125gr JHP.
296 with a 125gr JHP and CCI Small Pistol Magnum Primers: Start 21.0gr, Max 22.0gr per Hodgdon's website.
I loaded these up at 20.3gr using a Remington 125gr JHP, but am concerned with the overpressure signs. My measured velocity out of the 6" barrel was 1494 fps, which seems right in line with where it should be.
Yes, I know you are not suppose to drop more than 3% below start charge when using 296, but the danger is a squib, NOT overpressure.
I also included some cases with 16.0gr of 2400 for 1453 fps. with the same 125gr Remington JHP. These do not show any issues at all.
BTW: at these pressure levels, 2400 generates much more flash out of my SP101 (which I was using as well) than the 296.
I am very leary of loading 21.0gr, much less 22.0gr of 296! Any thoughts on how I should progress if using 296? :banghead: My easy answer is stick with 2400
