Yup, my plan was to have 23.7ish in the middle of my ladder to start off from when you mentioned it before! Weird part about that load range is that is where 75&77's started to get good as well

I don't, sorry. They were in a bulk bag of 1000 his dad bought at a gunshow 10 years ago (during the last Dark Age of Reloading.) They look remarkably like the Hornady #2266, however. I have about 250 of them left, if you are really interested PM me. I don't really have any use for SP bullets.

Now that is hilarious as I too found the same thing with the RMR 69gr!

I tried TAC for the first time last year. And it's become my second favorite powder for .223. I would recommend starting your loads where the Hornady and Ramshot data intersect. Go up from there in you desired increments. My best accuracy came in at 24 grains of Tac with 55 grain bullets.

Hornady data is always lower than the powder manufacturer for all powders that I use. I load a lot of TAC and Hornady bullets and I always go to the powder manufacturers website for data and only use Hornady as reference check.
I’m definitely comparing 223 to 223 data. The Ramshot 5.56 data is hotter still and I don’t t have a need to do that.
only my test load was about 1.5”. The rest have opened up to around 2 give or take. They also get worse the further out.
I don’t think I’m going to get the test charges loaded in time for tomorrow. It may be just a zero confirmation session.

I was shooting the Hornady 2265 and 2266 55gr bullets from a Savage Axis 1:9 twist and can say that the BT version shot smaller than the Flat Base. Like you I was getting 1.5"-2" groups but when I went to the 62gr bullet groups immediately shrunk to1" and under. So now for me it is time to try a higher quality bullet and compare.

Ramshot also lists 5.56 CIP nato/Mil data for that bullet 62350 PSI
So that should give you an idea of what might be safe,
Here is the normal .223 data
So they show 25.8 as MAX for .223 pressures, 27.3 as MAX for 5.56 pressure
Note: vels are from a 24" barrel
I think TAC is good stuff in .223, meters nice for making plinking ammo.

I use Hornady data, despite what some people say about it being to low. The middle of the road is just fine with me.
When Hodgdon uses the same bullet the data is the same as Hornady.
So if you are using the 223 data either one is fine, a test is a test, they are never the same.

In my testing, I found that the data Sierra uses, matched my rifle velocities pretty close for TAC.
I got to test the TAC loads today and found a good range around 24 grains under a 55 grain FMJ BT. Groups opened up above 24.4 and my top charge was 25. I’m using a 20” barrel. Anyone chrono tested a load like that for a better guess at velocity? I’m guessing about 2900 to 3000 fps based on Ramshot load data.
I could conceivably load up to the max of 25.8 grains but the groups would have to start shrinking fast to beat the mid range loads. That would put me up about 3150 fps if my guessing is right. Not really any reason to do it but it’s there.

Had a little trouble with the TAC loads. Tried a 9 shot group to confirm the good load from last testing. Some were hard to extract live rounds when the range went cold. Nothing to do with the powder but still. Had a couple of fliers but they were almost certainly me. I tend to pull one left sometimes and that’s where they were.

TAC is sensitive to temperature, so that does not surprise me. Normally if your in a node it does good. Varget is extremely temp stable, the reason it's in such demand.
