I agree. The case is full, in fact slightly over full and therefore slightly compressed. I've compared the firing pin impression with standard loads and it is similar, so I believe it is just normal. The case, too looks normal and is loose in the chamber after firing with no signs of sticking. Many owners of this rifle will ream them to .357 maximum with pressures around 48,000 cup without problems. I've not considered doing this, but I'm not aganst fine tuning for maximum performance. I believe I've found the max. load for this powder, now to fine tune for accuracy. Backing off the powder charge a bit and seating a little deeper and I just might have something.bgreenea3 wrote:Primers are good indicators of pressure but case expansion near the base should be watched too as a good indicator, at least that's what I've read over the years from ken waters and others smarter than I am. The primer troy pictured looks like its starting to show some pressure signs of flowing around the firing pin to me maybe just a little. I wouldn't go any hotter.
One thing that is bugging me now is that some folks have told me that the FTX bullet cannot be pushed over 1600 fps. Gander Mountain advertises the FTX at 3000 fps. I've written Hornady to get there input.
