Does anyone reload the .223 Barnes 70 Grain TSX for the AR?

The reason I ask is I'm wondering if it wouldn't be too long OAL for an AR. I know they have a 60 or 62 grainer but wouldn't mind the heavier bullet if possible but am unsure about the length. Any input would be appreciated. I have a 1:8 twist so that weight is not an issue as far as stabilization should go.

Not a problem, just be sure to use a powder that is not compressed with the long shank of the 70 grain TSX, I use 25.0 grains of Hodgdon BLC-2 in an LC '09 case with Wolf Small Rifle Primers. Seat the bullet flush with the top ring.

I don't reload, but I know it can be done because these people are selling just that.

Do you use a lee factory crimp die?

Thanks for the info.

No, you do not need any crimp.

Thanks! Do you think a small crimp would be better as it is in a semi auto? Or would that create a little more pressure that is not needed in this as it is seated so far into the case?

Never used a crimp and never had a problem in thousands of reloads, including the Barnes TSX 62 and 70 grain bullets.

It is normal to think you need a crimp, but you do not.
