22-250 AI 1st Shots Fired

[6.5x61Super]

I think I found the right combination with Ramshot Grand powder and the 80gr Hammer HHT bullets.

28" 1:7 McGowen Precision Barrel

Next load development will be with the Berger 85.5gr Hybrids.

Neat video.

Just a suggestion for trying to measure the results of your neck sizing.

The calipers you used will not give you a reliable value due to the shape of the contacts. May I suggest you learn to use a set of your other mandrel pins. I would use a good set of micrometers to first measure the pins to the 4th decimal because they are often not as marked. Then, you can use them like gage pins to check the neck ID.

Your rig seems to like what you are feeding it, so no worries unless you want to get a better resolution on your workmanship.
