My N110 load listed earlier gives me a 2104 average, FWIW

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.

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. :shock:

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. :mrgreen:

:lol: 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.

Results from 2 different rifles with the TNT 125 at 100 yards:

Image

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. :roll:
