secretagentmole 1,701 Posted July 17, 2012 Report Share Posted July 17, 2012 (edited) Whats wrong with a little 78? They are ok as long as they have enough CO2 in, they can be tinkered to over 10 and a half foot pound energy and are capable of bunny killing!

diggermad 154 Posted July 17, 2012 Author Report Share Posted July 17, 2012 cheers mole have been told that if its up to 10 if you hit them right they will do a bunny at 30yds Quote Link to post

diggermad 154 Posted July 17, 2012 Author Report Share Posted July 17, 2012 like i said rake were not all in to shooting on a full time basis its just a bit of fun with the gun long as you respect your quarry whats wrong with a little time away from your main sport to do a little something else cheers DM Quote Link to post
secretagentmole 1,701 Posted July 17, 2012 Report Share Posted July 17, 2012 These little guns have been tinkered and altered and are capable of knocking out about 11 fpe, of course not in the middle of winter! So as long as you are summer shooting it will be fine! Woodfield GCP are one of the main suppliers of XS78 tuning bits and pieces! Quote Link to post

secretagentmole 1,701 Posted July 17, 2012 Report Share Posted July 17, 2012 (edited) Link to his SMK XS78 page... http://www.woodfield...lubed-seals.htm Apparently fitting one of his seal kits will improve the performance, if you follow the video on the link and join the UK Chinese Airgun Forum you also get a discount! Hows that for some useful free info? There is a strip down guide on there explaining how to dismantle it, polish de-bur and polish the parts and reassemble, so for £18 or so (inc postage) you can do it yourself!

diggermad 154 Posted July 17, 2012 Author Report Share Posted July 17, 2012 i havent a clue mate better off someone doing it that knows what they are doing really dont mind paying though cheers Quote Link to post
secretagentmole 1,701 Posted July 17, 2012 Report Share Posted July 17, 2012 Well these are the bits to use, it is not that difficult, heck I am now rebuilding springers! They are more difficult to take apart than a CO2 rifle! Quote Link to post
diggermad 154 Posted July 17, 2012 Author Report Share Posted July 17, 2012 cheers mole but to be honest i dont have the time to do that and thats the truth Quote Link to post
Tron 173 Posted July 18, 2012 Report Share Posted July 18, 2012 (edited) Not that its applicable here in the UK but in the USA they can get 18FPE out of them Not a lot of shots though! 11FPE plus is easily obtained with a small amount of machining plus you dont need to fit stronger hammer springs, Its basicly a copy of the Crossman, like any Air or CO2 charged rifle more power equates to less shots per fill. Footnote, most of these rifles I have repaired have found to be strangled with the transfer port seal which is far too soft and obstructs gas flow I allways fit a harder UK made seal which just by doing that improves the power.

I put a different seal on the Ratty xfer port (without modifying the port) and the increase immediately took it up a couple of ft/lbs. I've used the SMK co2's and they have been fine in my hands. As for power I have used my HW40 pistol (less than 3ft/lbs) on rats out to 15 yards and a sub 5ft/lbs springer to kill rats at twice that range. Anywhere in the head or even the front third of the body and its not going to live more than a second or two. Tony 1 Quote Link to post
Tron 173 Posted July 18, 2012 Report Share Posted July 18, 2012 (edited) A bit more info for DIY members who like working on their CO2 rifles/pistols Remember dont replace existing O rings with normal over the counter ones, to do so causes all kinds of problems because liquid CO2 causes ordinary rubber to swell many times its origial size, causing seizure of any moving part with O ring sealing, The 78 range of rifles seem to use Urethane Transfer port seals which are clear when new but turn yellow when aging, Other CO2 safe O rings are Buna-N and Nitrile composition.

secretagentmole 1,701 Posted July 18, 2012 Report Share Posted July 18, 2012 When I eventually get my hands on one of these little things again I am just going to get a Woodfield kit, I like the easy life! Quote Link to post
