I asked their tech line about it, and they told me it measures close to the same length as the 110 interlock. I was worried about stabilizing it(with the what I thought at the time) with a 1:12.5 twist rate. As it turns out it’s 1:10; so I’m going to try em. I talked to a guy that ran em this last deer season. I think they have tapped an alloy that will be a force to be reckoned with! I saw a picture of one of his bullets. It was a beautiful mushroom! Like they should look!Hmm I bet it would be similar to the 100gr Barnes TTSX... I actually have a factory box of that stuff from Barnes that I really don't want to shoot until I get some bullets from them. Cause a 100gr copper .257 bullet should be a decent bullet. I haven't seen the 90gr Hornady ones yet either...
