crwilliams Posted April 9, 2013 Report Share Posted April 9, 2013 I have recently bought a revo semi auto and put around 25, 29 gram no6 game bore velocity cartridges through it, and sometimes it just doesn't fire. When I pull back the bolt it dispenses the used cartridge and then it's ok, the sportsman gun centre advised to put 32 gram cartridges through it (around a 100) and it should be fine. Any ideas, is it because it's new, or do you think I have a problem. Any ideas would really help, thanks in advance.. Quote Link to comment Share on other sites More sharing options...
HDAV Posted April 9, 2013 Report Share Posted April 9, 2013 (edited) hmm might be a bit tight, are the carts 65mm67mm or 70mm cases? 70mm cases tend to cycle more reliably some can bed in using a bigger load, not sure on the Revo is it gas semi? just noticed it is a 70mm case Velocity HV Pigeon 29 6 Fibre 8/70 1400 .............perhaps give it a clean and try a box of 32g 70mm shells and see how it goes.

OvEr_KiLL Posted April 9, 2013 Report Share Posted April 9, 2013 theres no harm in trying 32g, see if it cycles them ok it sounded like the cartridges were under 65mm but i just checked gamebore website and they are 70mm, so no idea Quote Link to comment Share on other sites More sharing options...
crwilliams Posted April 9, 2013 Author Report Share Posted April 9, 2013 thank you guys, yes the cartridges are 70mm.. If you fire in quick succession it seems fine but when you shoot one cartridge and then another a few seconds later, it doesn't eject the spent cartridge..I'll try the 32 gram and see ) Quote Link to comment Share on other sites More sharing options...

Take it apart and clean any grease oil from the magazine tube/slider, DO NOT over grease/oil. (actually check/clean all areas of the action) May just be a little tight but the symptoms sound like sticking grease/oil! No harm trying whatever!

figgy Posted April 10, 2013 Report Share Posted April 10, 2013 Give it a good clean. I run my semi auto wet with a thin film of oil on the action and moving parts. Figgy Quote Link to comment Share on other sites More sharing options...
