data for 63 gr Sierra spitzer .224 w Ramshot TAC?

[ghbucky]

I ran across some of these bullets at my local store, and thought they would probably work well in my 1:8 16" 5.56 barrel.

I have load data for IMR 8028 powder, but I can't locate any data for that bullet with Ramshot TAC. I tried to send a query to Ramshot, but their online inquiry form is broken, and I don't see a phone # to contact them.

I've ordered Sierra's manual, but I have no idea if they have TAC data.

Ramshot's online data doesn't list a 63gr bullet in this caliber. Speer, Lyman and Lee also don't provide data for the combo.

Is anyone aware of where I can find data?

Oh, well apparently the online form did work, because they already answered!

I'm to use 65gr bullet data.

The 63 grain flat-base and 65 grain BTSP have the same bearing surface, making the data interchangable, per Sierra.
You probably know you can download their reloading guide, which they update every few years.

Thanks, I wasn't aware of this.
