Does anyone know the minimum and maximum about of this powder for 55 grain 223 bullets? Specifically Hornaday FMJ/BT. I can’t seem to find any info on it. Thanks
xxxxx
I use 24 Gns. with a WW SRP.
24.5 grains has been an amazing load for me.
But if you google it you can find the various loads for all of the ramshot powders.
Thanks for the info on the link. That makes it easy. I’ve just started reloading for the 223, and have been using IMR4895. I’ve read a lot of good things about the ramshot tac here, so I think I’ll try it. Also, its cheaper. Thanks.
i’ve been using 26 grains with 55 grain hornady FJMBT bullets. i get just a hair under 3000 FPS with my 16" 1 in 7 middy.
accuracy is decent.
Why so hot?
Good question. I’d been trying out different loads and am currently on 25.6 grains… I may well just back it off a full grain since I mostly use 55gr for cheap fun, now.
Let us know how it works. TAC behind the Hornady FMJBT w/c bulk bullets is as accurate a load as I’ve ever shoot in bulk ammo.
I agree. Plus you’ll save needless wear and tear on your rifle.
I’ve been playing around with Hornady 75gr OTM’s lately - 22 grains of TAC, seated to mag length with CCI #41 primers. They’re chronoing 2450 to 2495 out of my 16" barrel.
I can’t tell if it’s just me or if it’s just not a very good load, but I couldn’t seem to do better than 6" at 200 yards with my 3x ACOG yesterday. With the can on it opened up to about 8". Groups at 100 yards weren’t so hot either, but I don’t have the targets here.
The surprise, however, was when I pulled out some of my leftover 55gr loads - the ones using 25.6 grains of TAC, mixed headstamp brass and cheapo 55gr bulk Winchester FMJ’s. I shot one 6 round string (suppressed) at the head of one of my 200 yard targets just to chrono them, and got 3 3/8" center to center, strung mostly in a vertical direction.
I’m still going to try downloading them a bit given the good results people have reported, but if I keep getting that sort of performance in general I may just stick to the 55gr projectiles.
I’ll be trying 24.5 grains with the 55gr FMJ as well as some other 75gr loads tomorrow.
makes the steel plates ding louder :o
i’ve actually backed it down to 25.5 lately. my logic is that i’ll get closer to 5.56 nato ballistics with a relatively hot load.
i’ve heard of people using 27 grains, but i’d have to work up to that real slow.
Haven’t you looked at Ramshot’s website? http://www.ramshot.com/powders/
Look at the “load guide” on the left side of the site. It’s a .pdf file, so you’ll need to have acrobat reader installed to view it.
That’s where I got my starting point for loading TAC w/ 69 Sierra Matchkings. Good luck!
Out of my 16" barrel. the heavier bullets prefer WW748 Ball over TAC. The 55 GN bullets like both.
Go figure.
I also use the 24.5 grains TAC w/55 grain projectile and it’s the best general purpose/training load I’ve found.
For heavier bullets, I use VV N140. Results are outstanding.
A little pricey, but if I’m shooting 77 grainers, I’m not shooting cheap anyhow.
Same here. I had a guy telling me I should try one of the other Ramshot powders since I’m shooting 55 grainers.
Why? Are you nuts? There’s NO downside to the 24.5 grain load. It’s accurate, cheap, and runs great in all my guns from Rifle to SBR.
I have used 24.5 grns of Ram Tac and had execellent results. I agree with everyone else here. It is a great powder not dirty and inexpensive. I have loaded many rounds with it and it works great.
It’s the official hand load of M4carbine.net! 
i’m gonna listen to you guys, just ordered 8 #s of tac from natchez shooting supply for 104$ plus 20$haz-mat, comparable to local prices of varget. gonna try it with 55 gr rem hp, and fmj. hope to give yall a good report, not exactly looking for extreme accuracy, just good m4 plinkering rounds.
I built up some nice 62gr loads and wanted more plinking loads with components I had lying around. Since I actually had range duty yesterday and it is usually totally dead in the mornings - I had made several batches of Ramshot handloads with pulled 55gr surplus, range pickup brass that I sized and trimmed to be uniform, etc, etc.
50-55 degrees, overcast skies and that day of infamy.
My loads were from 24.0 - 26.0gr Ramshot in .5gr increments - used a Remington LTR bolt gun to minimize external variables.
2 Best loads were determined by both low average deviation and more importantly, groups at 100yds:
24.5 RS - Avg vel 2863
25.5 RS - Avg vel 3073
I used some S&B as a base: Avg vel 3183 and the avg deviation was great than the aforementioned loads and still did not group as tightly - but that could have been me
