Ramshot TAC load data?

Everyone I know has been saying how great Ramshot's TAC powder has been performing for them. So, I finally was able to pick up a container today, along with some bullets recommended to me by the shop owner.

Problem is, Ramshot's v. 4.2.2 data manual doesn't list the bullets I bought, and it just skips over this weight class - even though it's a pretty popular one! Here's what I bought:

Hornady #2275, .224 22 CAL 60 GR HP.

The data goes from 55's to 68's, I believe. Haven't they ever heard of the SS109 62 grain bullet, hmm?

Does anyone have any load data for this bullet, or perhaps something in a very similar weight class? A link to something published, or a page from a current manual listing this powder & bullet combo would be greatly preferred, if such exists.

I'm using Lake City cases, and CCI #41 milspec/magnum primers.

Thanks to the forum for any assistance.

Re: Ramshot TAC load data?

yes I load a lot of 62 grain with this, in fact it is what I use for my trigger time loads and my M855 clones. I use Golden West 62 grain fmj with cannelure and pull down M855 bullets.
Lake City brass 24 grains of TAC, OAL of 2.245.

Re: Ramshot TAC load data?

I spent the entire Sunday today going through every load book I have:

Hornady
Speer #13
Lyman #48
... and Ramshot's latest, v.4.2.2

Really, anything I could think of that I had that would have some data in it. I Googled the heck out of my computer - all to no avail. The 4.2.2 booklet is the only published source I've yet seen with any data for TAC, and there's just not much.

However, something other than this has to be published out there. Does anyone know of another source for .223/5.56 TAC data?

Re: Ramshot TAC load data?

To answer your question:

As we all should, I much prefer PUBLISHED load data. In published I mean, from a bullet, powder, or reloading gear manufacturer. Actually, I much prefer multiple sources of data, so I can compare and contrast the data.

However, in this case I have no other choice but to accept my friend threefeathers' data. I did, however, check it against the published data in Ramshot's own booklet. Now, Ramshot's data isn't what I would like to have, as their data starts with all bullets 55 grains and under in a 1-12" twist barrel, and then jumps to 68 grainers and up in a 1-7 or 1-9 twist barrel. The two sets of data do not exactly correlate, as I understand that the faster twist barrel will generate slightly higher pressures, everything else being equal.

Threefeathers' data falls RIGHT in the middle of the two sets of data for the bullet weights immediately above and below it in Ramshot's booklet. In the absence of any other data, and after carefully reviewing Ramshot's published findings, I agree with threefeathers that this should be a reasonable starting point with bullets in the 60-62 grain class. To be safe, I'll reduce it 5% to start loading with (yes, 10% is the usual standard reduction, but in this specific case 24 grains appears to be quite a mild load for this bullet weight. Loads too light can be dangerous, just as loads that are too heavy - and doubly so in a gas operated firearm).

I'll try to report back once load development is complete for this weight class in the .223/5.56, so that others have some info in future. Don't hold your breath, though - it's gonna take a while.

Thanks

Re: Ramshot TAC load data?

That's how I started out and decided that with 62 grain i didn't care about burning the range up and I keep the load about 50 fps under what I chronoed M855. That's still an effective bulet and if it comes time to shoot zombies it will still work. I'd actually like to do more with TAC but it won't always cycle my gas trap Arms Tech USR while N540 and Varget will. The TAC will always cycle DI AR's. (I have 7 or 8 of them)
I was surprised when TAC didn't shoot 175grain bthp well but it did 169 grain.

Hornady's 7th edition manual lists TAC with the 60 hp. They tested it in a Rem 700 bolt action 26" barrel using Win cases and Win SR primers. Overall length as tested was 2.200". They had a start load at 21.6 up to 24.7 grains maximum of TAC.
