When placing the rubber ball on the stock spring, by normal speed. Do you mean for example a .22 cal shooting 18.1 GR pellets at 900 FPS with 600 barrel?
Hi Ernest.....great video as usual...but a bit confused about the rubber ball!! What part nr is it??? is it the 11599 or the 5110?? Would appreciate if you could enlighten me on this! Thank you in advance!
Where do you get that rubber ball and light spring? I have a power plenum mk2 and want to achieve under 500 FPS for backyard plinking. Is that possible?
--> wow you notice! Its a set screw one on each side of the front barrel support to lock barrel or minor left or right barrel alignment then lock barrel to minimize POI shift or to raise barrel slightly. Set screw are 1mm below center line of barrel. They have nylon tip. On my other impact both front and rear have set screw. FYI --> while cocking the cocking block force the barrel to the right when close light force to the left. With barrel lock down the barrel doesn’t move with cocking block sliding force affect.
Great video, i also want my MK2 pp to shoot sub 12 with a .177 barrel. Can you share the needed part numbers, i can not find the 3 spring kit on eBay. But probably the shipping costs to my country are higher than the part itself.
