Anyone know the minimum velocity for expansion of the 358 180gr TTSX?


I tried TAC today. Guys here report 2700+ with 52gr or so.


I had 50gr and a COAL of 2.274" and it felt awful compressed. I got 2550 from it.


Not sure if my COAL is too short or what. I don't see getting 2 more grains in there.

Only shooting deer and bear in the timber of the NE. 150yds is a poke. 40-75yds is the norm.


Not sure if I'm fast enough....?

Have varget and h4895 to try if I had to...not sure ifntheyd get me more speed.


Couldn't find 200s so went with the 180s I could find.

I shoot the same bullet at right about the same speed in my .358. I shoot 49.5 gr TAC because that’s what’s accurate and it’s about the limit before compression. I’ve shot deer, wild pigs and elk with mine. Zero complaints. Plenty of expansion.

Thanx for the reassurance!

Any idea what your COAL is? I have no idea how guys get 52+gr of TAC in there....usually with 200 grainers.... I may be seating too short though.


I know the TTSX typically performs better the faster you can send it...so I was worried when I was a bit slow.

Most 200 grain bullets are shorter than a 180 gr TTSX. Your bullet is 1.193" long which is longer than a 225 gr Partition at 1.175". Now if they're shooting 200 grain Accubond bullets that's a different story as they are longer than your bullet.

Want more speed? Got any 3031?

You seem to be including the plastic tip

No 3031.


I just wonder if my COAL is substantially short.. many guys get 52+ grains somehow.

Barnes says 1650fps.

Hornady 200 gr RN or SP or a 225 gr Woodleigh. Those TTSX in a short action or Accubonds are too long and the velocity is more suited for a cup/core bullet. Those Woodleighs are the bomb.

I do have a box of Woodleigh round nosed.



1650...I'm good way beyond I will ever shoot.


Maybe I'll see how they perform and reevaluate if needed.


Will have to compare my 225 accubonds and ballistic tips. The 180 is a flat base so I assume it may take up less case.


I've been running 200gr round nosed hornadys to fire form the brass. I read that they are designed for the 35 rem and won't fair well at higher velocities/bigger game. Not out of the realm of possibilities to shoot a 500+ pound black bear. And I like good bullets and horsepower because I don't like waiting for a perfect chest shot if I have a reasonable way to the chest. IE a frontal or quartering towards. Flimsy bullets make me nervous.

I load them for a 99, killed pigs at 50 to 200 yards one day last year. The pigs didn’t say anything about the bullets not expanding properly. Most fun hunting I ever had. I took 12 rounds that day, shot all of them, needed more.

.358 Woodleigh. 49grs TAC No pressure signs and would feel comfortable with more.

My son with the .358 Mannlicher Schoenauer. That is the exit hole! Complete pass through. 320 pounds

I load 52gr of TAC and get 2660fps with that bullet in my rifle. Last year I shot a black bear at 265yds. She didn't take another step! 😜

Thanks, Dinny

I use that bullet in my 350 Rem Mag. I’d expect that sucker to expand great down to the mins.

It’s real accurate in my rifle as well. Or at least as I am with the 4x on top.

I’d think it’ll be a hammer in a 358 as well.

If you're loading to mag length the plastic tip still matters in how deep you seat a bullet. Most 200 grain bullets are flat base and still shorter than a BT 180 grain .358 bullet. So they're not seated as deeply, so it should allow more powder in theory.

I seated some a little longer. Still off the lands. Working back up. We'll see if it produces anything better. I was gaining gaining about 50fps per half grain. So, the 52gr 2700 ballpark guys have posted about is likely true. Forget what they measured but it was just shy of mag length. 2.7xxx. 2.8 was doable but I don't like cutting it tight in a hunting rifle.


Stay tuned. Hoping to run them tomorrow before work. Wanna get the loads done before rutcation...I go back to work for a week and it's gun season. Not trying to get crazy right now with fine tuning. Decent velocity and groups will be sufficient. Also working on the little bushmaster....holding onto the little rifles and soaking up the recoil is a chore.

I wonder if RL7 or 10x might get you some speed with the 180’s.

Magnum primer will most likely up your velocity with TAC. When I run out of what I have loaded, I am going to use mag primers

Forgot to mention, I do run cci magnums in it.

I think the issue was seating too deep. I got the magic 52gr in there after I bumped the bullet out.

Ramshot recommended exterminator I believe when I emailed them. They actually projected a bit more speed than the beloved TAC.

51gr exterminator @2700
53gr of TAC @ 2675. 110% capacity.

24" barrel

Didn't list COAL. Those weren't tested but based on calculations. Probably quick load?

The .358 TTSX have massive hollow points on the 180 and 200 grains. Same with the 9.3 caliber. I can't imagine their would be a problem.
