100 yard Sub MOA with the TD257
Went out this weekend for a lil shooting/hunting. The wind picked up to a speed faster than what the weatherman said it would be:evil: WHAT’S NEW right? My plans were to coyote hunt in the morning the do a mid day jack rabbit hunt. But after the winds picked up and shooting groups, i called it a day. I did manage to pop one Jack Rabbit though with the 257 before i called it quits.
I had been wanting to finally get my TalonDor 257 to shoot a 100 yard Sub MOA group and i finally got it. I usually set my power wheel on 5-8 ALL THE TIME but for this group, i turned it down one full revolution to 4-8 and filled to 3200 psi. I wasn’t thinking though that the lower setting would print my groups LOW! But that’s ok, it’s all about the groups GIRTH (LOL) not were it impacts 😆 The group was shot untethered as i don’t own a regulator yet:
I then set up my AR500 steel spinner at 150 yards to see if i could repeat the group size by keeping it under 1.5″. I also switched the power wheel back to 5-8 for this shooting as it was a bit of a further stretch. At 150 yards, the bullet impacts at my scopes 4th lowest mildot. The first shot at the top left of the spinner was a sighter/test shot and i was overthinking about doping the wind and the shot went high left. But after confirmation, i placed the 4th mildot on the bottom center of the steel spinner. Group was 1.6″. Just over MOA:
More story coming soon as Doug and I got a new part in the works to UP performance on this gun 😉

Man, that is some fine shooting Cedric, as always. You may have mentioned this before, but either way, how fast were they moving? I never really noticed much of a difference in speed with only one full rotation on the power wheel. What kind of spring and hammer are you running?
This post contributes to the evolution of my AAA .25. First step is to get the 53ci tank with custom valve from Doug (when he finishes it for me). I will simply add this tank and valve to my current .25 24″ LW barrel in the hope that I will be able to move the 7 ring surefires a bit faster and see what they can do at 100 to 150. Next evolution (and this phase depends on how the surefires perform with that extra breath behind them) will be to convert over to a .257 barrel. If the surefires perform well enough, then I will leave things be and be thankful to save coin on a future barrel.

Tof,
Now that is consistancy, two groups under MOA and at different distances.
