Nice shooting. Time to make a bunch of those!

Yup I'm on it .lol I'm trying to get a supply in stock .lol I'm tinkering with my Brooks 450 gr chicken load and haven't gave up on the 510 Baco and 540PJ .
Hanz , PM me your address I can send Sample of what bullets I've been tinkering with. It's nice to see them fly before ordering a expensive mold .

Well the snow started to melt. Here's a few I found behind the 20 to 1 and 16 to 1 targets. All 70 gr swiss 1 1/2 . Not a big difference .001 less width in the nose just in front of the first band with the 16 to 1.

What are they now?
Surprised to see the rifling marks on the 16/1 alloy.

I got mixed up the dark 560 Brooks bottom left we're not 16/1 they were 50/50 WW and lead. Maybe I'm mesuring the wrong place on the bullet. Or I'm reading it wrong. The rifling just barely touch the nose.
I read .449 50/50 ww and lead

The PJ 530 20/1 .451
Am I reading it wrong? .lol

I would call the top picture .4495, and the other .451.
You are ck'n in the correct area.
Does the rifling make contact, all around the nose?

The 50/50 ww 560 brooks doesn't touch. All the 16/1 and 20/1 bullets engrave evenly especially with the neck tension and Redding comp seating die.
