HPA .25 HATES Cold Weather?
I have a HPA powered .25 caliber Talon SS w/ a bushy legend 5-15 (Thanks Don for the .25 barrel) and today I found my gun would not group. I was totally perplexed, so I tightened everything, lubed o-rings and filled the bottle…WTF.. same fliers etc.. So, I tried numerous things and put about 100 pellets through it and it still wouldn’t group. I decided to take a break. At this time the temp was maybe 34 degrees….
A couple of hours later, I walk out to my shooting area and begin to shoot both kodiaks and euinjins, they are shooting great! Now the temp is 45+ degrees and the gun is performing at its finest, I refill and shoot a few more rounds and the gun continues to shoot well until my pellet supply is eliminated…..
Any ideas what’s going on? My suspicion is that the valve is the problem. When I received the gun, the bluing on the valve was poor and it had a burr on the valve body preventing it from properly screwing into the gun, which I carefully filed off, so I suspect it may have internal imperfections too.
Any help Is appreciated!

Same issue with my B-51. I put some nice teflon grease on the hammer. Bad idea. Some shots slow, some fast, very erratic.
I now use dry Teflon spray lube. Same thing on pellets. Goes on wet, dries, well, dry. Slicker’n snot, and not temperature picky.
Ok, I believe you 😀
It’s all speculation until you wipe away the oily lubricants and try a dry lube … then you’ll know 😀
With one of my new guns this winter I was doing some chrono work in an unheated shop … velocities varied from 500+ fps to 1000+ fps in the same 10 shot string.
I took the gun back in the house and tore it down … cleaned off all the factory lube and waxed the barrel and hammer. Back on the chrono in that same cold shed a few hours later I was seeing 10 shot strings that only showed a maximum deviation of 17 fps.
My new .25 will keyhole CrowMags … but with Kodiaks and a waxed barrel/hammer she shoots nice little groups in weather that requires me to wear a winter hunting suit.
I really think this may be part of the problem, but do you think this could cause 2 inch fliers and keyholes?
GOOD IDEA. 💡
I’ve recently picked up a spray applied PTFE dry film lube that seems to be working well too.
There ya go ! A lubricant that dries is best me thinks. I put the wax on kind of heavy and let it air dry for 30 minutes then polish it off … if it’s the first time for that gun I use 2 coats.
Makes sense that a “wet” lubricant will gum up in cold temps and cause problems with consistency. I get my paste wax at True Value hardware and Wal-Mart will have it or the MinWax version in the paint and stains dept. For about 7 bucks a can you can “lube” your talon for a couple of years with it 😀

Johnson’s Furniture (paste) wax on the hammer and barrel … my guns work slick as wet ice in freezing temps … forget the oil use wax 😀
😳 I lubed the hammer with silicone 😳
did you lubricate the hammer or the inside of the frame? Try giving the inside of the frame, hammer, and spring a good cleaning and reassemble either with a very thin oil or dry lubricant. Silicone/grease type lubes will thicken at low temperatures and cause the hammer to “chatter” inside the frame resulting in inconsistency. just a thought.
Maybe the barrel had alittle machine oil in it, how new was it some times you must shoot them awhile, for them to start shooting good, I don’t know why this is I just heard from others here after a hundred rounds or so they had better groups. See if the same thing happens tomarrow.

I’m going to try putting on some moly and then wiping it off; moly leaves a thin coat of itself on things making them slick, so I think it should work…
