G.Day all.I remember in the late 1940s early 50s i had a BSA .22 based on the Lincoln-Jeffreys air rifle. It started to loose some power so the local iron monger sold me a pair of springs. My Farther made a screw driver from the poker as we had to go down a hole the length of the Butt in order to remove the breach from the butt. After a lot of swearing and that the new springs were fitted. Oiled up and leaning the Rifle against the shed wall in order to get enough purchase on the loading leaver it was loaded and ready. I placed a tin can on the top of a small box in front of the dust bin. Took aim and wow it not only put a hole through the can but also into the Dust Bin. It Dieseled quit a lot of the time. I went back to the Iron Monger and told him what had happened. He said that the springs were Morris 8, Exhaust Valve Springs that he had got from a Birmingham Salesman. GerryB |

Go for the hw80... I had a hw80e that had been fettled by a friend. When I bought it ex the local gunsmith's who had tuned it, it had LOTS of recoil, made a big thunk noise, and was down on power. He took it away and I paid him some money and it came back with a ticket saying 24ft/lbs on the chrono, had almost no recoil and a LOT quieter. I asked him what he did and he after some coaxing said that he'd fitted what amounted to the venom lazerglide conversion but without the fancy stock. I had to stop using promethius nylon pellets because it used to blow the insert out the middle and leave the nylon flight inside, until they came out with the high power barb'd version. Fantastic gun for rabbiting, very repeatable and my only complaint if you do is that they are LONG if you do a spot of shooting from moving vehicles. For that you would want the 80k version. The poachers choice :D ... Ive got a recursive bow nowadays... |

Want it to shoot good and legal, well as a springer any way. Sleeve the bore down and use the older not the newer HW77 seal or locally made Power Pulse seal Venom used together with a better light weight piston with bushes, alum ok. Titan XS spring, bearings, tight spring guide swaged in to end block. If youve made it right with correct tolerances there will be no twang so no underbody car sealant to damp the resonance and power all these tuners use. No grease or lube, it wont need any if made out of steel- metal on metal slides well with close fits, it dont slide too well when sloppy. Gave my 80 away in 98. |
