I want to droop a custom Maccari spring into a new 350 Mag, my question is for you in the know is:do you think the seal and piston/tube are suffiently lubed from factory so I don't have to pull the piston? Thanks
Unless the factory has changed their practices,RWS/Diana guns are assembled and shipped with little or nor lubrication.Although they will operate that way,it is less than ideal and the outside of the piston seal and rear of the piston should receive a light band of Maccari's moly.

I mean, if you're going to break the rifle down just to drop in a Maccarri spring, why not pull the piston and at the very least, give the whole action a good cleaning and lubing before re-assembly. If the OEM spring isn't broke or weakenned, you may reconsider dropping the JM spring in it. Properly tarred (not too heavy or light) OEM springs will last a long time and usually produce higher velocities than JM's. His springs are smoother shooting though. OEM springs normally just need a good polishing on the ends to make them less "torquey",.... if there's such a word. If you want to increase the velocity some more,...alot of folks toss the piston liner all together and add thrush washers &/or a top-hat. My 350 clone was a beast as far as speed (high 900's low 1000's with Kodiak/Baracudas), and I replaced the liner in the piston to slow it down some. It also acts as a buzz dampener to a certain extent as well. Shoots in the low to mid 900's now!!
You wont be sorry. I did the Vortek full power kit in my clone and the 7.9 gr. pellets were way over 1300 fps. So I opted to exchange it for a vortek reduced power kit. The 7.9s were still just shy of 1000 so I switched to the JSB 8.4 and get 965 fps. I just switched to a Beeman FTS 8.8 last weekend and have not done a chrony on them yet but they slam home like a hammer driving nails.
I think I will get a Leapers/Centerpoint for the 350 Mag with a 1 peice mount. Do you think the 3x9x32 pa 35yds correct will hold up? I like smaller scopes that I can mount lower. The most powerful Vortech kit for the 350 sounds like a scope killer?
./...since the cocking arm is hinged, sliding the cocking shoe out of the cocking slot is an easy task because you will not have to remove the barrel. i can take mine apart w/ my eyes closed now. call me if you need help. - paul d self. 817-986-7767.
