Love my CFX well worn in and since i upgraded seals and spring to a gas piston its been a very nice gun runs a 3-12-40 AO Artic fox scope Recently brought the BSA seems to have good power and not bad accuracy but already had to fix the loading mechanism as it wasnt seating the pellets correctly easy fix tho put about 300 pellets through it unfortunately things went down hill and lost all power so decided it was a good reason to upgrade to gas piston and better seals from Custom Air seals opened the gun up and sure enough seal was toast and gun was full of oil makes sense why it was dieseling so much found something in the compression chamber tho which id like some advise on looks like metal perhaps the cylinder was not machined properly i have some pictures i can post used a bore scope.

This is at the Transfer port end and there are dents in the piston seal from all this material 

I have the .22 CFX and it is a firm favourite.

I will post a review of my .30 Hatsan, hard work but it does reward and is surprisingly accurate.

 when BSA/GAMO were independant stand alone companys their guns were much better than they are today,there was nothing wrong with early GAMO guns,ans BSA had allways produced top quality guns,but its not like that today thats for sure,the damage to your rifle is very likely due to poor machining and quality control,but may have been allso caused by oil in the tube from manufacturing etc,its allways a good idea to degrease new guns then lube them properly before firing particually with spring guns,i like to strip them these days as have found bitz metal left over from machining inside several brand name spring and pcp guns in recent years so i never assume any more things are as they should be with new guns,as for remachining and polishing your tube,proberly dosnt need remachining,just removing the junk will proberly sort it,then lube it again with the right lube and new seals is proberly all it needs,as there is lot heat produced inside the tube the gunk inside maybe hard and difficult to remove,sugest blocking the hole with wooden plug and trying petrol or brake cleaner to soften the gunk,this should get it out so you can check for any roughness or damage to tube,

 hope that helps,if any machining needs be done that can be fun as it will be right at front of the tube where you cant see what is being machined and would likely require a long boring bar that will need to be well supported to prevent the tool chattering etc but hopefully wont need that.

Just a update on they cylinder the material down the end was weld from when they attached the end to the air chamber i have ground most of it down took a verylong time as it was very hard hopeing for some good results .

 cheers mike

Indeed the BSA Spitfire 10 is just a Gamo Maxxim with BSA branding, stock, but also the BSA cold hammer forged barrel which is very well regarded. 

It should use the standard Gamo seal. 

I have one on the way at a good price from trademe. I emailed Daisy (who control Gamo / BSA) and they dont have the manual or parts diagram. Its also not on the BSA website, but I think that just shows whats available to the UK market.

Also new seals

I have made the move from firearms to airguns due to licencing issues... (Processes not losing my licence) and am looking for like minded people to get together from time to time to shoot and chat? are there any clubs who regularly meet up?

Stephen

Hey Stephen id be also interested in meeting up with some of you guys not sure about clubs but there must be some.

Hi,

and welcome. If your 13yr old lad is a 'good size' he should be OK, but I have the .25 cal Hatsan (same gas ram as a .30) and they are heavy to cock (40+lbs), and after a 'few' rounds you'll feel it. I did look at the .30, but decided on the .25 for two reasons.

 1) there are several youtube reviews of both, and the .25/.30 are pretty close for FPE and hitting power.

2) the .25 cal has a much greater selection of pellets available. I've used mine with 24gr slugs, and the heavy 42gr. (this produces similar muzzle velocity to the .30cal) I can attest at 40mtrs on a bunny, the .25 hits hard.

This review I found interesting, .30 vs .25

Hey Graywulf yeah he can cock the .30 but only a few times its more the weight of the gun that gets him but i have the Gamo cfx and Magnum which is better suited to him i just recently pulled the .30 apart cleaned all the sh*t out it was really dirty inside almost looked like rust bore is all good tho put new seals in and charged the gas ram up to 170 bar it really feels like its shooting alot harder now the factory seal was terrible the piston just fell out compared to the new one which was not easy to get in there haha but feels good now still waiting on my chrono to turn up and see what it is shooting at .
