Auto comp or titegroup for PCC??

[Hi-Power Jack]

Sounds like if you're using an effective comp, you want to go with lighter bullets and slower powders

to work the comp, like WAC.

 

If you're not using an effective comp, you want heavier bullets and faster powders  ???

Is there a source of energy content for each powder - it might make load data easier to deduce but I expect energy release is also related to the pressure curve - more pressure more efficient energy release.

 

I still intuit that fast powder is better in a blowback action.

A powder that I think would be worth trying is Sport Pistol. It's supposed to be identical to N320 in burn rate, cleanliness, etc., but at the price of Titegroup.

How about Shooters World Clean Shot. Runs like a champ in my PCC. Burns clean and is very accurate.
