The 6UM

I know, right?

BAT Machine actions are by far the better R700 clone versus Defiance

Why?

 

[IrkedCitizen]

Better attention to detail, quality control, small owned business not a conglomerate. BAT actions just exude high craftsmanship.

Pretty sure there are just as many defiance as bat actions at the top level benchrest and f class events around the country.

I like bat better myself, but when raw micro-accuracy is the game, they compete at the same level.

I'm not crazy about how they have bats all over it. Also, they aren't made in Montana

Ace had unknown do a barreled action for me with a 1:7.5 twist.

66 of n570. Granted I didn’t spend a lot of time with the load before hunting season. And there are a few things I want to double check when I have some free time. It’s hard to find the time with a newborn right now…

Here are the 3 charge weights I did all 60 thou and 115 dtac’s

Did you get pressure signs? What's your goal?

Faint ejector marks and a good speed and group. I wanted to see if I was on the right track with my gun and see what others were getting.

BAT dominates short and long range BR by a huge margin. You’ll almost never see a Defiance. Borden are pretty of common but still get outweighed by BAT’s. F Class sees probably mostly Kelbly followed by probably Borden and BAT, hardly any Defiance. Defiance still makes a fine action. I prefer BAT but I own Defiance and there’s nothing wrong with it at all.
