I know there are many reviews on here about both. I am looking at the 200 grain hard cast choices in each and would like to know which brand you guys are finding to be the most consistant and making factroy stated velocity. In short, I want a factory load that will push a 200 grain hard cast bullet a solid 1200 fps out of my Sig P220. Thanks.
I would recommend Underwood based on what I have seen inside and out! 8)
However Double Tap is right up there too!
Underwood will be a little warmer consistently but double tap loads a better 200gr bullet in my opinion
I haven't fired the Underwood, but the Doubletap cast loads are very nice. I even fired the 230 grain load through a Glock barrel, and it worked fine.
I carry the DT 200gr Hard Cast in my Glock 20SF in the back country. Very reliable feeding.
I also like Underwood and carry their Gold Dot 165gr JHP as a back up mag in 10mm.
