You are on the right track. I happen to use IMR 4350 in my 30-06, but the Hodgdon version is pretty close. I shoot 59 grains of IMR 4350 in my rifle behind the 150 grain Tipped TSX for 3000 fps. I have not managed a 1/2 inch goup with this load as of yet, but have gotten darned close. Starting around 56 or 57 grains is probably a good idea.

I have, and use Imr4350, with 150 SGKs, very accurate. 56 grains is a great practice and target load in my '06.
But I picked up a jug of H and now it's time for hunting loads.

62ish in one of my rifles. That's Hodgdon's max for a 150. I never got the claimed velocity from it.

Make sure you seat them .050 off the lands, not just shy of the lands. Don't ask me how I know. If you do that, most data for other bullets should be pretty close. Work up, and see. In my '06, 61 grs. shoot really well with the 155 Scenars. The other thing is that brass can vary and so can the best, or top loads. So, work up. I'd start at 57 grs. and see how they shoot. E

Yep...and you may find that you need to get closer to 59 before those groups start to shrink.

Am I the only one who finds the Tsx shoots better closer to the lands, like 5 thousandths off?

My most accurate loads have all been .030" to .011" off. I've never had much luck with them close and I've tried in .224, .244, .264, .277, .284, .308 and .358.
I'm not implying that your rifles don't like them close. Just stating my experience. Each rifle is different. I've also found best accuracy when they're pushed close to max/at max too.
I enjoy handguns and I really like shotguns,...but I love rifles!

Kenneth: I've also experienced best accuracy seating the TSXs out close to max. recommended OAL with at least a couple of cartridges, namely the .308 Win. and .257 Roberts.

I've noticed some of the new ttsx bullets have just a tiny bit of contact at caliber width before going into a groove...almost as if to just get the bullet centered. On those I wouldn't be afraid to snug up to the lands at all. Nosler is doing the same thing on some of the latest etips......the have a wide band machined in just a smidge below the ogive.

What I've found is that the top end is very close to the standard cup and core bullet if they are seated at .050 off. But that doesn't mean that closer than that won't result in better accuracy. E

My experience with TSX/TTSX in all calibers is that they do indeed like a little jump and in most cases, a good crimp. The only exception is my 280AI, which doesn't shoot crimped bullets quite as well. Although the difference averages about 1.25" crimped vs .75" uncrimped. The recoil isn't bad, so crimping to reduce further bullet seating in the magazine is not necessary. If the mag/action length isn't limiting, I usually start at .050" and find the sweet spot there or very close. The ejection port on My Montana Ls requires deeper bullet seating to be able to extract unfired cartridges without a lot of gymnastics. My loaded rounds for the Ls are very close to OAL of factory loaded rounds. That certainly doesn't affect their accuracy and the bullets are well beyond .050" from the lands!

Where is 62 grs. listed as max?
Would that same number apply to the 150 TSX?

Over at hogdon.com they list 62 grains with a 150 ballistic tip at a 48,400cup which isn't smoking hot. I've pushed the 150ttsx to 3100 w/no pressure signs using win brass and re17 in a 23"tikka. I wouldn't be afraid towards work up to 62 h4350 in my gun and think it would work out fine.u

Yes what he said. They list starting loads at 56gr and max loads at 62gr.

Ok, My Speer manual lists 59 as max for 150 BTSP and also as being compressed. 62g must be sizzling right along...
1 thing about the Barnes manual, it lacks info like no other.

Absolute total BS that they "need" to be way off the lands. MM Necromancing this thread after finding a few boxes of 168 grain TSX and, miraculously, some H4350 in stock. Have yet to load for my .30-06, but here's where I'm intending to start: -One group at each: 54.5, 55.0, 55.5 grains H4350 -Federal 210M primers -Seating depth set to match the COAL of factory 168 grain TSX ammo that my rifle shoots right under MOA What changes would you make to my process?
