Spring in cold (winter) ?

[drpietrzak]

So I have read that springers are affected by the cold. It is not clear to me how much they are affected. So if I shoot my TX200 on a day (or indoors) and it is 70°F and then the next day shoot it outdoors at 32°F what should I expect to be the change at 25 yards?

Are you going to be plinking or hunting? Mine likes a few shots to warm up if I am plinking. But it doesn't do much to mine when hunting

Much less sensitive than Co2, but more sensitive than pre charge air.
Except if running a Leather piston seal….I have never noticed any fluctuation when running one …
A good tip is keep your heavy grease down on springs and pistons as it can thicken, or thin out with temp change adding to the issues….

I shoot more for targets at 25 yards and 50 yards.

I shoot in the winter all the time. No real POI change due to temperature. Biggest problem is the wind and having to wear gloves to shoot. Foot Joy sells some really nice winter golf gloves. Can still manipulate a .177 pellet when wearing them.

All my springers are lubbed with Ultimox, space age lub designed for use in outer space. High $$, like $30 an oz. No POI changes with temps from below zero to 100F

I have less poi change with the spring then the gas ram guns in temp changes.. lol.. i gell for gas ram cause the hype it resolved all that but / better , but i uet to see it honestly its worse..

Few years back i tested a ram by zeroing it at 78' when it was hot in the afternoon but cool in the morning and at a 55' ot eas like a 3" difference , bit when I he temp got back to around the 78' mark ot was back near zero again.. kept wondering why i was missing squirrel shot early morning hunts but hit laye in the afternoon... Now i know...lol

Thanks. I appreciate the feedback.

Whatever way you go honestly ly there fine. The spring is more tunable as well or if a good onown brand like hw or diana , hatsan replacement seals and springs are easy to get. Mote fun lks tune them . Some hatsan rams can be pressure adjusted with there pcp probe and pump. Did nt onow if the latest ones can or not. Only had one ram fail but lucky i was able to send it in for warranty no charge to me.

Thing is in weather hot air expands and cold contracts. So how your gun takes to that may overall affect that poi changing ..

I find no difference shooting springers in the winter. I was out yesterday 3 times for a total of 3 1/2 hours, the high was 35 F. Had to thaw myself out a few times. Grabbing the cold barrel or lever is the problem and the wind. You have to wear gloves. I’ve shot several times in 0 F. If there’s a wind in cold I don’t shoot. I’m heavily protected from wind except from the North which is the coldest.
I thought that the cold would affect the scope and gun as well, especially with sweating. I think I suffer more than the gun. Crow

Which direction,up or down in the morning? I'm thinking it would be lower as the heating of the air in the cylinder wouldn't be as much as in the afternoon. It's called Adiabatic heating and it's why diesels run with out needing spark plugs. It's also why you have to use silicone oil in the compression chamber instead of mineral oil.

No it rises as it heats up .. low cold high hot.. like today i set a dark blanket in the full sun and let them warm up first and that gets me darn close to last i left it. When the temp gets close to where i zeroed it its pretty much back on target ..
Like ke i daid could be all in the nature of any particular gun on how it does overall.

That's what I figured would happen. To cold for your rifle to over come to get the added power that comes from Adiabatic heating. That's why diesels need glow plugs to be able to start when the temperature is to low.
