Good information.Affirmative black butterfly. It was with an origin action and black collar arms chassis on a xcaliber barrel.
Like @Old Man with Gun said if you plan on running heavy subs, run the numbers on the revolutions needed to stabilize them big pills, when I ran the numbers I was close on 1:14 but would’ve prolly needed even faster.
Now running those 425gr buzzsaws out of a 1:16tw 16” barrel they stabilize fine and wallop deer.
I plan on buying a 16” 1:16 option at this point, but it’s good to know that even so, I need to be cautious and test stability before putting a can on.
