Ramshot TAC for M1A?

TAC sits right next to H4895 on the burn rate charts I've seen. Anybody know for sure if it's OK for use in M1A's or Garands? Anybody using it?

I have used it and "Highbrow" has IIRC. I have developed a load capable of MOA accuracy if I do my part with my Sage EBR. (another member here can verify that claim)

It works good enough in my Socom and Polytech too. It might be a little bit temperature sensitive on the extreme cold side... jury is still out on that one, might have been me shivering

Really... I liked it enough to buy 4 kegs, it meters very good and the price was right. I paid as low as $93.00 bucks and the last keg I gave $105.00 all in the last 2 years. This was before the "Gun salesman of the year" was elected though.

Excerpt from Ramshot burn rate chart http://www.ramshot.com/powders/

95. Hodgdon BLC-2
96. Accurate 2460
97. Hodgdon H335
98. Ramshot TAC
99. Hodgdon H4895
100. Accurate XMR 2495
101. Alliant RL12
102. IMR 4895

I have used Ramshot TAC with my M1A for a couple of years without any problem. I emailed the folks there looking for a load using various combinations and they always responded with good data. If you can't get IMR4895 reasonably, I'd use the Ramshot.

Have shot a fair amount of TAC with 147gr pulled fmj. Used 40 and 41gr TAC in my standard M1A. All went bang, and accuracy was as good with the fmj as any other powder I have used (IMR 4064). Don't know about temp sensitivity, as it seldom gets more than 90F where I live, and I don't leave my ammo in the sun.

I've used 42gr Tac with a 147gr FMJBT and get military ball velocties from a SOCOM 16, 2550 avg. It's cheap and clean and is good from training/plinking loads.

Highbrow I said that mostly in jest... it was very cold and windy that day and I couldn't hit for poop. I had to blame it on something I've shot with TAC in extremely hot weather and never had an issue with it in the heat.

Nothing work as good as tac in my LRB. It likes 150 MK, or Noslers.

Thanks for the input folks! I've got 16 pounds of TAC and H4895 is hard to come by right now, so I guess I'm gonna work up a TAC load.

Just a suggestion, see if you think it worthwhile. I emailed Ramshot at their contact us page and gave them powder, case, primer, average temp and humidity, altitude and they came back with a couple of recommendations that are tack drivers for me. M1A Standard, bedded, NM sights. I also told them length of barrel, twist, carbon not chrome and gave them a description of the M1A.
Made a big difference for me.

Good thread guys. I'm also starting to use Ramshot TAC for .308 reloading too. I contacted them through their website to get advice on M80 type loads using this ball powder. In the course of the conversations one of their ballisticians indicated that TAC, as a modern military grade spherical ball powder, has a coating which keeps the flame temperature down and somewhat helps throat/barrel life. He indicated that this was a result of having to meet rigorous military spec's for barrel life. As info. Todd

Pat's reloading had some pulled milsurp powder iirc WC844 and WC846 one was designed to reduce throat erosion Pat's warned that powder (wc844) would not reliably ignite tracers but (wc846) would.

I wonder how that will effect "Tracer" performance (ignition) when using TAC? Has anybody loaded tracers with TAC?

I'm using 46.5 grains of TAC with 125 grain speer TNT in my Socom II. very accurate load.


I also use it in my .458 Lott with 350 grain bullets, very accurate and clean burning with zero problems.

I like 41.2 gr of TAC with 168 SMK's. Gives me great accuracy and 2575 average FPS.

The only problem I have with TAC is when I use the CCI nato spec primers. Not sure if they are hotter or what, but I get erratic grouping - 4" at 100 yds with Hornady 155 AMAX. Going to try it with a WLR and see sometime this spring.

Anyone else have the same experience?
