Any load data for Hornady 129g Interlock bullets?

[ragedracer1977]

I have H335, TAC, and XBR.

There's a shoot this weekend, and I can't get my hands on any 123gr SST's like I usually shoot.

Hoping someone might have some data for this bullet as it's all I could find.

Thanks!

There is data for TAC and 8208XBR for the 129gr Interlock in Hornady's 9th Edition:

8208XBR-2.245" COL (work COL out in your chamber) 22.4gr was their start load, and max was 26.2gr work up in .2gr-.3gr increments, no more. XBR is known to spike viciously with 123gr, so don't go near the max load and just load from there, especially with a longer bearing surface flat-based bullet.

TAC-23.6gr start load, max load 27.3gr

Those both maxed out at 2300fps from an 18" barrel for Hornady's testing.

Cool, thanks!

I'm just going to 'blast' these, so I'll go low. I have a bunch of 123g SST on the way, but they won't be here in time to load for Saturday morning. Just wanted something to make noise with and maybe hit a plate or 2.

Using the 129SST I'm getting sub-moa with 25.9g of 8208. AA brass, COL 2.260, CCI-450 primer w/18" Liberty/Saturn barrel.
