Have you had a chance to do any load development?

I've got mine all put together thanks to @ormandj for the dies and brass.

I used this as a reference: https://shermanwildcatcartridges.com/sherman-reloading-data

I did a little myself, I'm shooting a 195 berger with RL 26. I used two different cronos ( knowing one was not calibrated correct.) I took two shoots of each load, marking each velocity.

For some reason I can't upload my photos of the data, probably user error, but when I can, I'll send you my data.

I finally got out and managed to start load development on mine. I loaded 10rds of RL23 and RL26 going up in 0.5gr increments starting at 55gr. I was kind of amazing I got to 2800 with RL23 at only 57.5gr when I didn't get to 2800 till I hit 60gr of RL26. I'm not looking for crazy fast speeds and 2800 was the goal, so I think I'll test a little further around 57.5gr of RL-23.

I did have to seat the 175gr ABLR a little deeper than expected as I hit the lands at 2.890" COAL. Seems almost like a waste to not have them out closer to 2.950", but I will see how it goes.
