What are you guys getting in 20" barrels with factory ammo?

Please list ammo, and if it's in a custom or factory tube. Thanks.

    Thanks - good info, not bad at all for 21" and 147s. Sounds like a great combo and surely deadly as well as accurate.

    Great info! Thanks much. What affects are typical with cans? Decrease in speed, or little change?
