McGuire Ballistics .277 High BC/Heavy hunting bullet

McGuireBallistics · Thursday at 7:40 PM

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

Excellent! Hope works in 1-8 twist. Would think something in the 155-160 range. Not sure could go heavier than that without sacrificing bc like the heavier Barnes or needing more twist

It most likely will be roughly around 140-150 grains but we will see. I think any heavier than that will actually work against it. We will be basing and using a 1:8 twist for testing.

That makes sense. I did not know where the range was but figured at some point you can't add weight without sacrificing BC.

Excellent, will be ordering some to try. What do you think the BC will be?

That's pretty cool, makes a 6.8western a lot more appealing

Sure wish it was a 160gr!!!

I have a 1-7.5 Brux I might try it in.

a fast twist 277-308 or 277 fury would be interesting depending on minimum velocity for expansion. too bad I retired my 270-338rum imp.

Count me in. My new 270WSM LongAction would like a steady diet of those!!! That along with the new ADG brass should be a killer combo!

I am hoping for mid .600s G1 range.
