I have an M1A and I wanted to try some Barnes 130 gr. TTSX to hunt deer.   Has any one had any experience  loading these in a semi auto firearm?  I usually use LC brass.  I anneal it, cut the primer pockets flat, clean and polish it along with all the other case prep.  I will probably use CCI 34 primers.  I have a keg of Data 223C that is on par with AA2460 for powder.  Just want to know if there are any ejection problems with such a light bullet?  Any help appreciated!

I run them in a 20" AR10 with a high pressure bolt.   They are awesome, very accurate across a wide range of powder tests.  The deer I have used them on were all down within seconds, all pass throughs.

I should mention that I am only pushing them to 2800fps but have run them up to 3050fps.  Ram Tac and BL(c)2 have provided the best accuracy.

They should work fine as long as you work up a load in the normal manner. I have loaded 125 gr. bullets and shot Fed. 130 ammo with no problems. A friend only uses 110 gr. JHP in his M1a Scout and it runs great too.

I've used them in a semi auto before, they worked fine.

However, being confined by magazine length, the TSX (no tip) can give you extra length to play with vs. the TTSX.

Just something to consider when dealing with solid copper bullets. Quick AI numbers I see are the 130 TTSX (1.173") being longer than at least some 147gr FMJ's at 1.16

Bullet length isn't the only consideration, but when dealing with magazine limitations, it can be an important one.

Thanks.  I've  used tsx in an ar15.

OP, if you don't end up likening the TTSX's, try swift scirocco's, they are an excellent hunting bullet that flat works.. In 308 they offer 150/165/180  and range from .430 to .520 BC and are extremely consistent..I've loaded them for years and killed everything from moose, grizzly's, brownies, wolves, wolverine, and fox and I don't remember what else I am forgetting, but they work excellent from point blank to over 600 yards for us...
