Hi,
New to these forums. Wanted to mention that many people on the mdshooters forum have had good luck with the Swamfox Gunworks 10mm loads. Some of them are max-nuclear, though (as high as 1525fps 800 ft/lbs energy with Hornady 155gr., and heavier weights too) and fully-supported barrels are recommended for those. He seems to still have Gold Dot's in, which can't be said for many these days.

He does have 175 gr. Silvertips, rated at 1350fps 700 ft/lbs energy@ Muzzle from a Stock Glock 20. His 155 Silvertips do 1450fps 720 ft/lbs.
I haven't tried DT, but I have seen some recent negative YouTube publicity of chronographs that were as far as 250fps off of what the box stated (10mm).
