Ram Shot Tac users Let me here you loads!

I recently found a local place that has a lot of this powder at normal prices, I have also read where this powder is good for the 6.5GRR? I plan to run the 123gn ELDM from a 18'' and a 24'' barrels, I would like to hear what you guys have to say about your load data for a 1&8 twist on these barrel lengths, and the 120gn pills,

27.2 and 27.4 under a 120gr NBT both hit in the same spot and both were sub-MOA. Looked like a critical charge weight area so I settled on 27.3 and it is lights out.

I like TAC. In fact I need to go looking for some more. I'm glad to read that it's showing up again. I'll check first to see if there's any available locally before thinking about buying online.

Fired through my 20" BA stainless DMR barrel, here's my results of a workup set using 123 gr ELDs. They're all pretty good groups. I want to load up a bunch more at the max I used: 28.2 gr. Velocity wasn't amazing. Just 2467 FPS. But it's fast enough for target work.

Thank you guys, This store claims to have at least 2 more cases of this powder, after I purchased a case of it already, so IMO it can't hurt to buy more!

Midsouth shooters has Tac, and several others in stock as of now.

Thank you. Picked up some Tac and 2520.

Thank you. Picked up some Tac and 2520.

I was going to mention, my rifle (the BA 20") shoots TAC and AA2520 about equally well, all other things---aside from load weights---being equal. Meaning, during my testing, with 5-shot groups, my max of TAC, 28.2gr, and my max of 2520, 29.6gr, both shot sub-MOA and were only a couple of FPS apart in velocity and both with low SDs. I plan to try loading up batches both those loads in the future to see with comes out on top. Max loads are the lower right bulls in both targets.

Note that the groupings below show a pronounced vertical component. I attribute it to sloppy shooting technique; was shooting prone and the rifle has an A1 fixed stock on it. So my collar bone was starting to feel it after a while and the hold became inconsistent.

Thank you for your input!

another vote for 28.2 gr behind 123 amax/ eldm. Has worked well in 3 different barrels for me. not the fastest load, but seems consistent.

I have 4lbs of AA2520 to try as well as the RAM Shot Tac, The Tac seems to be usable for the 5.56, 6.5GRR and the 308win, but I mainly purchased the Tac for my 6.5GRR and my 5.56 tubes,

My problem is all of my reloading manuals are out of date, so I just ordered the 11th edit Hornady and the new Hodgdon manual, so updated information with some of the newer powders as well as some the older powders will give me more info, my older Hornady manual shows the Test barrel @ 14.5'' with a 1&7 twist, not very useful to me!
