Dreamsinger, what kind of velocities are you getting w/ N110?
Re: Recipe for Speer 125gr TNT
This is my favorite bullet also. On sale this weekend thru weideners, 65 per 500. I use CCI 450 (magnum) primers. Load to 2.1, powder is 110 or 296. Im running 18.8 out of my Daniel Defense 1:8 10" uppers. Very accurate.
Re: Recipe for Speer 125gr TNT
Whats the feedback on a longer COAL for a single shot Handi? Or do you folks feel stay around the 2.1 length.

I would definitely experiment with loading longer for your single shot rifle. For supersonic loading you stand to dramatically improve performance on game.

For a single shot I would seat about .080-.100" of bullet in the neck, or .010" off the lands, whichever is longer, then fill it with 296 and rock&roll.
But since I've made it this long without getting banned from this site, You should do the same but start at about 21 grains and work up.

You have been been answered by one of the forum wizards.Should you choose to follow the path, there are many steps to learn before attempting. As dellet and I were just speaking on the phone and it's fresh, I'll say there is a huge difference between a guy that dumps powder and seats bullets and a guy that understands why his seating depth, powder charge and bullet choice work. It isn't magic, It's knowledge and understanding. Keep the questions coming sir.dellet wrote: ↑Thu May 21, 2020 3:51 pmstewmagoo wrote: ↑Thu May 21, 2020 2:09 pmI appreciate that!

Re: Recipe for Speer 125gr TNT
Results from 2 different rifles with the TNT 125 at 100 yards:
Center and lower left groups were from my 16" bolt action Model 7, which apparently doesn't like the TNT, but at least it shoots subs very nicely. The 3 smaller groups were my 10" SBR. I worked up to 19.0 grains of W296 in testing, but I had a few flattened primers from one of the rifles at that charge weight, so I backed off to 18.5 grains for the rest of the run. Judging by the length and profile of the TNTs, they don't appear to be specifically designed for BLK and I had to seat them deeper than I would have preferred in order to have a decent amount of bullet held by the case neck. I ended up at 2.060" OAL and the primers used were CCI450. Cases are re-formed lake city. At 18.5 grains they chronoed at 2051 out of the SBR, and 2212 from the bolt gun (which didn't like them).
While I was disappointed that they shot poorly from the M7, on the whole I was pretty happy with them, considering that the ammunition was hastily assembled on a progressive press using some of the cheapest components I could find, and it still managed to group decently out of a 10 inch SBR lead hose. I intend to buy a lot more of the TNTs if they ever become available for purchase again.
