My philosphy for any gas gun is to meter primarily with valve dwell, soApril 16 2017 at 11:30 AM

for me, the match/sporter distinction is small at the valve construction level.
I wouldn't strangle the port or minimize valve volume, but I would use the lightest striker (and longest throw) I could make work.
I've found that a little more throw(less than 1/8" over stock) means a faster valve opening and less jounce to the gun (compared to a slightly heavier striker to get the same velocity)You get to keep the spring very close to stock levels that way, which has it's own benefits.
I'd expect the lower limit on striker weight using cartridges would be getting a good pierce in the first shot or two.
