I left my HW30 cocked and loaded for about three months. Speed was down to 530 when I ran it over the chronograph. I had a Vortek Steel kit PG4 for the rifle and installed it this weekend with the VAC seal. No issues with the install, everything went smoothly.
I ran it across the chronograph with H&N FTT 8.64's and was only able to get 580 fps for about 6.5 fpe. Vortek's website says the kit is good for 7 to 9.5 fpe with the VAC seal installed.
I cleaned the inside out and used a small amount of the grease included with the kit. I applied a small amount on the outside of the VAC seal and spring as instructed. Was a simple install with no drama. However it is slower than I expected.
Any recommendations on how to get it a bit hotter? What did I do wrong for it to be so slow? I have shot about a hundred pellets through it and no changes to velocity.
I am wondering what tuning secret I am missing.
Thanks in advance!
