I Really want him to cut me a barrel in 10mm. He may have some suggestions for you with regards to the tight chamber.
Geeman, the 10mm was not chambered in the Encore by T/C, it was however, a Factory chambering in the Contender. I will just do it that way in the future. I need to just get the damn scanner out and get it scanned. The T/C Book only provides the loads I showed on the table, since this is data from '91, a 200gr bullet may not have been available at that time.

I have a PDF copy of Alliant's load data on my ipad, however, I must not have looked that deep into the chart because I hadn't noticed the data for 2400, and for that I do appreciate it. Keeps me honest, and helps keep others honest.
I appreciate you clarifying my misinformation about 2400. My intent was simply to offer other published load data. I /Know/ some of our more aggressive loaders here do go over book max in their loadings in their guns. I simply wanted to CYA since the data I was providing was marked as "for the T/C Contender Only" by the publisher. Not at all Shadow, I appreciate the discussion, AND, you showing more load data. This can be accomplished because the round doesn't have to fit in a magazine.

If you decide to lengthen the free bore, you can load for a much longer OAL and fit more powder and slower burning powder into the case. One more advantage for the single shot too. Add a longer barrel to the mix, velocities are in a different class. There is also near zero pressure bleed off through the breech. I'm sure FPS will be greater for a duplicate in a T/C, even with the same length barrel, just because the pressure rises faster and hits a higher peak pressure. A blown primer in a locked breech is better than a blown case destroying a pistol, but its not good to go there in either! If I'm going over the limits, The Encore will certainly handle that better. Now I think a hot load in one is a hot load in the other. Going into this I thought I could load hotter loads and I had to make sure not to allow them into my Glock or the Witness pistols. My experience with the Encore barrel is that the primers show more flattening than the same load shows in the auto pistols. When there is less room for case expansion, the chamber pressure is higher. 002 expansion on a fired case! A loaded round doesn't drop in. Because there is no need to autoload, these chambers are tight. For that reason, most (all?) 10mm are custom chambers. I don't think T/C ever chambered for the 10mm simply because the extractor system works better with a rimmed cartridge. Well, I had a barrel custom made for the Encore and what I found went against the conventional wisdom. But this shows the reason that you can never have too much data to reference. So I guess I muddied up your post somewhat, with the comparisons for all to see. It too may be close to the same pressure like that which Mike McNett was showing for the 200XTP as tested. But I would bet it too was highly compressed loading. Yes the 2400 load in your post was even higher than what Mike McNett was testing.Īnother relationship, is that 190 grain bullet being a JFP would be a shorter bullet than that of the 200XTP, thus allowing room for more powder. He was compressing the powder so much that it deformed the nose of the XTP, I have seen this with heavy charges of the AA#9 as well. 2400 is a slower burning powder and it takes quite a lot more powder to make the pressure changes, as show in a T/C test done by Mike McNett of Double Tap. Therefore I wanted to show you that even Alliant did publish tested data for 2400 in 2006.Īlthough the 2400 data was shown in the T/C Only data to be above Alliant's published info, I was trying to show a relationship of the amount of the charge weight to the pressure.
