McGuire Ballistics .277 High BC/Heavy hunting bullet

[McGuireBallistics]

Can't wait to see it in action. Thinking about doing one in a lefty for my son.

It should be allot of fun...

This is what I'm using now.

Maker bullets: 160 Grain .277 High Velocity Tipped Expanding Bullets (Box Qty - 50)!!! YOU MUST CALL BEFORE ORDERING. THESE WILL NOT WORK IN ALL GUNS!!!!!, Projectiles, 277160THV

How do you like the maker 160s? What caliber? I was looking at those for my fast twist .270 Winchester.

We will start on a heavier high BC .277 bullets through the winter. Waiting on components to begin. We are open to input. This will be roughly the bullet we start with.
.277 Dia
1.600 Length
150ish Grain weight

It looks like I'll have to build a 270wsm!
