59 has worked great for me. Is that a compressed load? Barnes lists a max of 55.5 with 97% density for the 168 TTSX. No pressure signes? As many guys that are quoting that charge weight, I'm not going there. Guys that want to exceed the boundaries by that much are on their own... They may not know what pressure signs look like either, so beware when out on the range..
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

59 grains of H4350 SC with a Barnes 168 TTSX gave 2826 fps and 61,700 psi (m43). I had better luck (as far as velocity) with Superfomance.

This was what I thought initially, but if you look at threads about this combo there are a lot of guys saying their most accurate loads come from 57-59 grains. My rifle is showing zero pressure signs of any kind at 56.

Well, best accuracy might be 57 - 59 grs but what does that have to do with exceeding SAAMI pressure?
Unless those loads are below max? Wish I knew. I can only go by velocity. I will not exceed book velocity for any cartridge. Not smart enough ( or foolish?) for that.
I am waiting for my bullets and brass to get shipped. Very anxious to work up a load for Elk next season

62ish in one of my rifles. That's Hodgdon's max for a 150. I never got the claimed velocity from it. H 4350 has been slowed down in burning rate since it was introduced as AR2209 whereby I have seen velocities as light as 2880fps using that 62gn load. This makes it safer from the manufacturers side, but unless you use a chronograph continually, it is harder the monitor the variance in powders either by batch or over time. I do get very fine accuracy using that 62gn charge but when velocity is the goal, that is where 760 proves ideal with 3080fps usually obtainable from a grain less.
When truth is ignored, it does not change an untruth from remaining a lie.

Wanted to update this- was having chrono issues with my previous loads. I'm now getting 2825 FPS with 56.6 grains from my 24" Model 70 Supergrade, so going to try moving up some. No pressure signs as of yet. Copied the factory stuff's COAL as it shot well in my rifle, just varying charge weight now. Have a ladder up to 57.5 grains loaded for my next range.

Am I the only one who finds the Tsx shoots better closer to the lands, like 5 thousandths off? Every rifle I shoot them in shoots well with them just off or even a kiss of the lands. Absolute total BS that they "need" to be way off the lands. MM I did some tests with my 7mm08 and found them to shoot best at .020" off the lands. I found it odd that it didn't perform better when they were .100" off.. When I start loading for my 30-06, I'll keep this in mind...

[quote=Eremicus] Make sure you seat them .050 off the lands, not just shy of the lands. Don't ask me how I know.
Why is that?
