BATs are super nice, just a little spendy. I've looked at them also. I'll take another gander however.
I'm really liking the looks and sounds of the Prometheus. Can get them for around $1175-1200 which is a good $300 less than the Impact, and $600 less than the BAT. And the bolts are cheaper also, provided you wanted to switch calibers. Not a deal breaker there. But with all 3 actions having the same features, but the Kelbly is $300-600 less, seems like a really good deal. Unless you guys can convince me the BAT or Impact is worth the extra $3-600 over the Kelbly, I'm about 90% set on the Prometheus right now.
I'll be going with a Bartlein 28" Rem Varmint 7.5 twist to start with. My smith is only a 30 minute drive away, a retired machinist who now puts custom rifles together for guys all over the country, and specializes in target/match rifles, R/Os a lot of the matches when hes not putting rifles together. He makes some very good shooting rifles. I have confidence he can get the job done. He did my R700 223 Wylde last year, and he's done a slew of guys builds locally that I've shot with and they've got a lot of wins. The last MOA/KYL match I went to, the top 3 place shooters, including myself were all spun up by him. Plus the turn around time is like 2 days if you bring him everything he needs. And he is very fair on pricing. $150 to cut/chamber. Not a bad deal all the way around honestly.
