80Gr Bart's Dominator BT

Sorry, it's a 80 gr. Need the measurement of the base.

Thanks

Dave, just curious, what twist will you use with the 90's. I shoot the 80 grn Dominator in full size 6BR out of a 12 twist, 33.7 guns of 4895 gives 3400 fps out of a 25 inch barrel. It shoots pretty good. I won a 200 yard VFS match last weekend with it.

I'm just wondering if a 12 twist would stabilize the 90. The 80's are on a .925 jacket.

I think the 90's are out of the same die. As you can see, the 80 is exactly .243 just ahead of the BT junction, with about a .0003 gas ring at the BT junction.

8 twist is what I have Jackie.
My mistake, it's the 80gr I changed it above.
Thanks for the reply.

I posted the wrong weight on the original subject line Jackie. Bart's website doesn't list 90 gr. I imagine Tony's are 80's. I'm going to shoot them in an antique Br built in 91 with an 8 tw.

Thanks
Dave
