I cleaned my Impact Pellet Liner A (.25) this morning and it was absolutely filthy. It had been a while and accuracy was falling off.
I had tuned for 850 FPS with MKII.
I shot 16 pellets over the chrony and was surprised the first shot was 818. I had heard that a clean unleaded barrel would slow the velocity but didn’t expect this. A check of the regulator showed no change from the other day
As I shot I saw the speeds creep up and level off in the 830’s where it stayed.
Deleting the low shots gave me an average of 833 FPS with an ES of 7 and an SD of 1
I think I’ll just leave it alone and see if the speed comes up.
Of course this is the 8th weekend in a row of high winds. Wednesday’s are our calm days haha, so I might have to check for accuracy then.
I’m sure this has been discussed before but the pellet liner just seems more extreme?
FYI I wash and lube my pellets.
Happy Memorial Day. We interned my father to Arlington Natl. Cemetery in late 2017
