What? Can you share that load data? Hornady says 21.1 for h4895 and velocity of 2550...Book max is over 23 I believe at a short coal

I should have put it in my previous post about the 77sWhat? Can you share that load data? Hornady says 21.1 for h4895 and velocity of 2550...
Hornady data is for 60k. They state that the 5.56 nato is rated to 60 even though it isn't lol.Not sure what data T28w is referring to. I assume the Hornady data is based upon 54k PSI and a SAAMI chamber? Significantly different from a longer freebore and not limiting oneself to 54k PSI obviously but I bet those loads got significantly above 62k PSI too!
I'm not sure. Will check when I go to load the next ones.At what point were you compressing loads?
just because you can, doesn’t mean you should!I saw on ultimate reloaded they took a 308 win in a bat machine action up to like 80 or 90k no pressure signs. I think they were getting 300 prc velocities.
Yeah, it does. The worst advice or comment that can be given in a reloading discussion, regardless of a wink and a smile emoji.Doesn't necessarily mean you shouldn't either.

That's a good post. Loading manuals for as long as they've been around have said when reaching max charge, that's where you stop. Regardless of signs not being present. Of course getting signs before max charge and playing the game of my gun is different than anyone else's, is not the best idea. However, folks push charges until they see signs, and back off, even if backing off is still over the book max. It just doesn't make sense. Go up to a bigger case, shooting the same bullet you want to use, and safely meet or easily exceed what the over max loads get in the current gun.Maybe he was just showing with some guns you can be way off from where you think you are if you are waiting to physically see signs of pressure? Almost a warning of sorts.
I have not loaded 88s but if he is running with 24ish with the 77s, that’s not even really that high depending on where he is seating it, which seems very shallow if he is .050 off in a tikka .223.
Yea I would never do that lol. It was a good video because it really shows you how insanely far your could go with a good action and good brass. They even say in the video do not do this. They had all kinds of monitoring stuff. However it does beg the question if you can run a good action with good brass at such a high pressure then whats going on here? How many loadings could he get? What is the actual max pressure and what is a good factor of safety? Is it dangerous? Is saami overly cautious and what is their factor of safety?I shoot 223 to get 223 velocity, and to get good barrel life so I can shoot a lot. So as other have said get a bigger catridge. I only load to book max. I do not load over that. My guess is saami pressures have a good factor of safety of atleast 1.5 but thats a guess... also if you want more speed you can use varget or staball match or cfe 223, Hornady lists 2700 to 2750 for all those powders out of a 20" barrel, for a 24' 2850 isn't out of the question for staball match.just because you can, doesn’t mean you should!
Good post, best of success as you keep up the diligent work on making good ammo.the 88 eld is 2.465 COAL, so certainly not your usual Tikka throat/mag confines over all length. Even so, these loads are obviously way over pressure. I knew I was goin over book max, and to be honest, I expected to see more visible pressure signs on the brass. I probably should have stopped earlier, but curiosity got the better of me. I have done lots of load work ups over the years, but never with a small bolt face Tikka, and I'm very impressed by how it handled the pressure. Rest assured, I'll back off and load to sane levels.
I have been using these in my tikka 6.5creed and tikka 223 and they have worked perfect. over 100rnds in both no issuesIf you don’t already have one You will probably need a mag that offers a longer coal than factory to get the 88s seated far enough out to get enough powder in the case. Along with a lot of freebore.
