Tuning Stupid me. .22 Gauntlet 1 velocity question

[Guest]

I did some porting work on my gauntlet .22 1st Gen and completely forgot to get baseline numbers. It is now shooting Crosman Premiere 14.3 gr domes at 915 fps. Do any of you have a stock gauntlet.22 you can chrony? I’d like to know if what I did increased velocity much. Nothing else has been done to the gun besides an upgraded air stripper and baffles.

My son has a first gen that's still original, it may be Sat. or Sun. before I can get you some speeds off it.

Here is what my Gauntlet did right out of the box. I did not shoot any Crosman pellets across the chrono but here is the data from the pellets I did shoot. There was 5 shots in each string. Looking at the data below I would guess that my gun would have shot the Crosman 14.3 pellets somewhere in the low to mid 800's in factory tune. Hope this helps.

Initial chronograph data with gun exactly as it arrived from the factory;

That is great. 915 isn’t too bad then with the little amount of work I did
