308 130TTSX 3300 FPS

[JRay]

I recently developed a load for 130ttsx in my 22” Kimber 308. I used resized Hornady brass and CCI200 primers. Following the Barnes load data I loaded 47,48,49 and 50gr of TAC to 2.75COL. The ambient temp during testing was 60deg. According to the Garmin, 49gr produced 3290fps and 50gr was 3300fps. That’s 50fps faster than the Barnes max load at 51gr. Neither load showed signs of pressure.

Has anyone else with a similar setup seen velocities like these?

Wow. I pushed 130s out of a 20” X bolt at 3030 and was getting swipes. I’ll look up the load data later.

I've loaded this bullet with Varget and BLC2 and I couldn't get anywhere close to the book's max velocity, even subtracting 50fps for my 22" barrel. Could be one of those situations where you might not be seeing signs of pressure, but you're over pressure.

I run mine with 53.4 gr of Win 748, they’re going around 3220. Haven’t noticed any pressure signs with that load either.

My load is 50.4 grains TAC.
COAL was 2.810, Starline brass, and CCI 200 primers.
I may play with this some and increase it to maybe 50.7 grains this spring and see how this shoots.
My MV for 50.4 is 3178.8 fps ave from a 20” barrel Tikka T3X compact.
49 grains was average 3130.4 fps
When I got up to 51 grains I was getting consistent MVs around 3208 fps, but I was also getting a stiff bolt lift.
Temps were around the same as yours when I was testing, and given that your rifle is 2” longer I would think that were in the same vicinity.
I tried to find a group with Varget, but could’nt get anything that was consistent AND the MVs were a bit slower (2900 fps) than with TAC.
