Thank you much. Nice velocity for the 11.5.

Have you pulled any? Stick or ball powder? I wonder if it can be replicated with a double based ball powder like BLC-2, CFE 223, AR COMP, etc.

Supposedly there are very few people who are not under NDA's, who know where the stuff comes from. I was explicitly told it would be a bad thing if I detailed any of that, and taking pictures of proprietary propellants qualifies, in my mind.

Excellent, I assumed this would be the case. Should be very easy to replicate this load safely with the type of powders I mentioned.

Today I finished working out a handload for this round, accuracy and did a video shooting some 2 liters with water. I will post up the video when I have time to process it. Probably some time this week. Early in the development nearing the upper end I had some issues with the winchester primers being blown out. I usually use CCI and did not notice when filling the dillon that I put in the winchesters. Was chasing the load a bit until I noticed that the primer was a winchester when I was under 25 gr of TAC. Anyways here is my final results.

Velocity average 10 shot string out of a 14.5 barrel. Best velocoty out of TAC over Varget

Barnes 70tsx / LC Brass / CCI 400 small rifle / TAC Powder
OAL 2.250
25.8 GR TAC
Velocity: 2740fps 14.5" barrel

I think these will work out great for my 11.5" barreled AR. So far so good. I really want to try out some of the 62gr offerings as well.

Sounds good!

Now, I am NOT a handloader, nor would I hold anyone on a forum legally responsible. That said...

Is it reasonable to expect that if I use all of your ingredients, and have a properly chambered 5.56 rifle, that I should see 2750+-50fps safely from it, if 14.5", as above? Or are various powder lots finicky/not "corrected to an average" or however you'd word it and do I need to work up to it, or what?

Two seperate things.

1. Original load is provoded from barnes starting at 24gr-26gr of powder.
2. With any load as not only can it vary by powder lot, but by yoir location, to be safe you would always want to start 10% lower than stated and work up to the suggested load. This way you can check for pressure signs while loading. As well taking into account that the oal is within specs it will work and feed in any mil type spec rifle.
3. I do not have the equipment to test the pressure of this load though I would recommend always a .556 type chanber I did not see any warnings barnes when going over there data. It can be found here.

Find the 70gr bullet on the site. And see data for yourself.

As far as fps you could be close on your average but there are enviornmental concerns here. I dont think you would have an issue though as I am at an average enviornmental for the us.
