Yeah, okay, never mind. Have at it and good luck.Ok I will try to get my COAL this afternoon and go from there. I wonder why I wasn't getting powder compression though... weird.

I just meant why they list at the max Sammi COAL and 56gr of h1000 they are saying it's a compressed load? When I had more powder at a slightly less COAL and didn't have any powder compression signs? I'm just trying to understand how that works. I do agree with you I'm getting awful close to excessive pressures with my powder charge based on their load data. I also found a guy on another forum saying he loads 58.6gr of H1000 at basically Sammi COAL and has zero pressure signs??? Just odd as I'm getting good ejector marks at 57.4. I would think unless he has a super crazy long throat and very hard brass he'd be at least blowing primers let alone hard bolt lift.Yeah, okay, never mind. Have at it and good luck.
No no I got what you and @GeoDudeFlorida are saying, I just overthink stuff all the time so I get random stuff stuck in my head and drive myself crazy wondering about one specific thing... I will pull the 156gr bullets out of that ammo and dump the powder back in their respective canisters. Ill restart with just H1000 and calculate a 100 percent case fill according to Bergers data and see what that lands at grain wise and compare it to their min-max. I do appreciate y'all being so concerned for my safety guys, I really do.Seeing that data, I’m suspecting that the combination of being quite a bit over max, and your oal being quite a bit shorter, you got a very substantial pressure spike. Seems like you might be trying to come up with the 6.5 PRC sig fury if I might quote some wise words from my gramps that got me started reloading: “I think you’d better back it off a bit, bud”. (I’m just rereading that and it sounds condescending! And that ain’t at all how I meant it! Was trying to be funny!) Spoken around a toothpick while sucking bits of bacon and coffee from between his teeth.
You are dealing with pressures in excess of 62,000 PSI. Don't screw around.
No offense but it really should not take a computer to tell you that.Found out some kind soul has uploaded the Berger 156gr 6.5 bullet profile to the GRT discord so I downloaded it and imported it and look what shows up!

57.4gr of H1000 shows a pressure of 62600psi!!!!!!!
Yeah I kinda figured as much but I was just glad to see two different things saying the same thing.No offense but it really should not take a computer to tell you that.
Berger says MAX is 56.1gr. Why go over max? If you need more rifle, buy more rifle.57-57.5 of h1000 seems to be the sweet spot, I've hit it with 140s and 147s.
I didn't say go over charge I simply said there's a sweet spot with 140/147 bullets.Berger says MAX is 56.1gr. Why go over max? If you need more rifle, buy more rifle.
Well you have or will have spent more than 50 on ocw so we've come full circle. Pick a powder and run with it to know your gun until you meet your need or determine you need a different bullet and need to start over. I've never used h1000 but I hear it's a fine powder... I'd stick with it until your out and can't get more or you determine it will not meet your need.Ok I loaded up a more sane load ladder tonight.

There’s some important lessons here mostly having to do with orders of operation but also with basic information gathering. Orders of operation matter. Things like determining the use cases before buying the firearm, requesting load data from the bullet manufacturer before purchasing components, and measuring seating depth versus chamber length. Starting a load work up without any significant information leads to wasted time and expense. I would consider this a good learning experience and keep moving.Well you have or will have spent more than 50 on ocw so we've come full circle.

Oh how I’d love to have my own shop and test lab… I’d have wildcats out the ears!
