I was going threw all my old stuff getting ready to load after many of happy years of shooting. I found a box of 100 Speer TNT 50gr hollow points, now as memory serves me I cant remember if they were not supposed to go in the 22-250 or if I only put them in 223?

I found recipe for the "NEW GREEN TNT" but I dont know as it they are different?


Thanks

I dug out my old Speer Reloading Manual Rifle & Pistol No. 12, copyright 1994.

It shows 50 grain TNT loads for the 222 Rem (which it was designed for), the 223 Rem and the 222 Rem Mag.

Loads are NOT shown for the 225 Winchester nor the 22-250. In the 22-250 section it states: "The 50 grain Speer TNT hollow point is not recommended for 22-250 velocities."

It's not the velocity that breaks up the bullet. It's the RPM. There is a warning in the 223 section of using light varmint bullets with 1:7" twist barrels. It notes the RPM of a bullet doing 3200 fps in a 1:7" twist turns in excess of 300,000 RPM.

The rifling cuts those thin jackets and they don't stand the spin.

Hornady SPSX are the same way. but, boy do they splat the PD's nicely.

Made the 223 grow up to perform like a 22-250. Still not as much range but flying guts were the order of the day.

Now I shoot 40 grain VMAX at 3800 FPS with great results.

I use Hornaday 55 gr SXSP in my 22-250. Excellent load, and they're not blowing up. My twist is 1:14", but I also have a 28" barrel, giving me another 200 fps with 760 powder.

The TNT was Speer's answer to Hornady's SX line in those days. I used the 50-grain SX extensively on whistlepigs and crows in both my .222 and .222 Magnum and they were superb. I once tried them experimentally in my Swift, slowing it down to 3600 FPS and the advice was spot on, not a one of the 10 rounds made it to the 100 yard target. But boy, when you hit a crow with them from the 3-Deuce or the .222 Magnum, there was nothing but a sootball of feathers.
