Re: 160gr Matrix

I just look for color change. When they start to get a burished look, I stop. The time depends on how hot your torch is. With good heat, you can do it in 8-10 seconds but the propane torch I have right now isn't very good. I don't know much about the CEB's hardnss so can't speak to that? I know on a bullet jacket, it makes quite a difference. You can feel the "stickyness" in your dies when you are swaging and they collapse much easier if you aren't careful. I stopped bonding most of my bullets for this reason as it is a catch 22. The lead sticks to the jacket but the jacket is softer........Rich

Re: 160gr Matrix

I am hoping to do some testing with the 160 gr matrix bullets this week in my 6.5 Sin. I believe I will be in the 3400-3500fps range. I did some testing with 140gr bullets yesterday, not maxed out yet this is what I have reached so far. I am pretty happy.

Re: 160gr Matrix

No idea on barrel life yet, I want to get it nitrided to extend the barrel life. I would be willing to bet I could hit 3600 with the 160gr after I do that (maybe before). I would hope for 2k rounds after that. It is a 6.5 Sin, still in development right now.

Re: 160gr Matrix

I was able to squeeze off a few more 160's in the WSM after a long day on the ranch with my out of state crew. I'm at 62.5gr of N-570 & still no stick bolt lift, primer flattening or ejector marks, velocity is 3100+.

I honestly thought I'd pressure out there, happily i'm wrong! I will probably load up some more from 62.5 to 64.5-ish.

Time will tell, just thought you gents would like the update.
