I picked up a 223 wssm the other day and want to try the 70 TSX in it. I would like any powder recommendations or experience with this combo.

I had a 22-250 that liked the 70 grain speers. I know the TSX is a lot longer but the 22-250 had a 1-14 twist I believe. 1971 Rem BDL.

This rifle is a super shadow mod 70 with a 1-10 twist.

My son has owned a Browning 223wssm for about 5 years now. The heaviest bullet he's shot is a 60gr Vmax and 60gr Btip. We used RL19 for the Vamx and 4831sc for the Btip, gettting about 3,700 from each.

I use the 45gr Barnes XLC in my 22Hornet and 222remmag, as well as TSX's in 243, 270 and various 30cals.

I have a 26 inch .223 9 twist that stabilizes them well, and a 20 inch 9 twist that won't stabilize them at all.

With a 10 twist barrel you'll be lucky to stabilize them if you push them really hard.

I have a 24" 1:10" twist 22.250 that won't stabilize the 75 grain AMax. How long is the TSX in comparison?

I haven't personally owned the 223wssm, or shot the 70gr TSX's, but from what I have seen over the years on a few boards the WSM/WSSM's tend to like the lighter side of bullet weights for caliber, pushed really hard.

You are in a "shoot it and see" situation. Both of my balistic programs show it takes 54,000 Cups(too high) to do 3700fps. At that speed it would take 1/9". If the bullet did not have a boattail it would would work in a 1/11". Another Barnes bullet that will only work in a non-factory barrel. But if it was not bt than you would lose that 3/4" of drop at 300yrds and that is important to everyone. NOT!

Kinda been thinking that if they dont stabilize Ill just cut the boattail off and try again.

Shot some of these this last weekend.

They looked to stabilize just fine.

I shot two different powders or was it three? Dont remember, my notes are in my car.

Anyways minimum velocity was 3500 fps.

Thanks for the test. I shoot the 62 grain in an 8 twist bushmaster, but never thought to try them in the super short with the slow twist. I'll have to give them a try.

I have a Browning WSSM and it doesn't like the 70TSX. As said above, my 25 and 223WSSM's like to be pushed hard.

Give it a try in your and let us know. Different applications, but I have a H-Bar 223AI bolt gun and a LMT 1/8 AR that shoot the 70 TSX very well.
