Many of you know I just started reloading and for now I'm focused solely on .40 (and I'm fine with that).. However I am a reader and I've been snooping around on the net and one thing that confuses me.. I've got my g20 loaded with underwood 155gr bonded hollow point, and I've been doing some underwood stocking when funds are loose.. I find these underwood loads to be awesome at he range, and as hot as blazes.. There has been much underwood testing by folks on line and although I don't have a chrony I'm reasonably comfortable that the advertised fps is on the money... So here is my question... In my Internet snooping I've yet to see loads that recreate the kinds of performance I've seen from underwood.... So it begs the question... What do companies like underwood do to goose so much out of their ammo Wanna kill these ads? We can help!
