I agree, pretty impressive. I have a couple 10mm Revolvers, a 610 and a 310 Night Guard. I have had the 610 for around 20 years. I have been carrying Winchester Silver Tips for carry ammo. Looks like these folks need a serious look. Full House 10mm is not a common offering with most ammunition makers. I have tested Remington 10mm ammunition what was moving slower than their offering in 40 S&W. Pitiful.
I am sure the reduced loading is to keep the damage down on the old SS Smith & Wesson 10 Series, and Colt Deltas. The Glock 20 is the only carryable semi auto that would handle a steady diet of Real Full House 10mm and stay together.
