Shoot heavy pellets in a .177 spring gun

<< < (2/4) > >>

Mark 611:
yes I agree with you on this one I think these would be to light for use in a rifle but may work well in a pistol!

I've wondered the same thing. I own both guns and have used the 10.5gr in the Quest 1000. I did break the spring, but then I have broken the spring in all of my guns, at least once, until I tuned them and lubed them properly. The Crosman Quest 800 calls for spring  part # B19-00-4A for the .177 and #B18-00-4D for the .22 version. The B18-00-4D is the same spring used in the Quest 1000. I've replaced the spring in my Quest 800, .22, with the B19-00-4A (800 fps). It gives me a smoother shooting cycle and still plenty of power for rabbits out to 30 yards. Like another poster said, shoot what you want and order an extra spring and seal from Crosman, in case you need them. Spring is $5.70 and the seal is $3.60, plus $4 shipping. Happy Easter to everyone. Safe shooting.


Okay, gonna throw MHO in here on this one. I'm by no means an expert but I take the word of those that are. I enjoy working on my AGs but enjoy shooting them MORE. I'd rather not cause maintenance or put stress on my equipment. I want them to perform and to do so for a LONG time. The right pellet chose is a MUST. Too light of a round, as mentioned, will not produce enough resistance when fired and will cause the piston to slam in the chamber. That can cause the spring to break or damage the seals. Even though they may be maintenance items, HOW long of an interval between relacement? 50 shots or 5,000? I prefer 5,000 or more. Check out this articleby The Pelletier Tom Gaylord. HERE[/b][/i]

On the other end of the spectrum, a too heavy pellet will also put stress on the internals and cause unnecessary low life expectancy.

There's other considerations too. Going super sonic will cause a pellet to tumbledown range. This will cause a loss of accuracy. The recommendation of the experts and service professionls is to shoot a variety of pellets in the middle weight rangeto find the round with the most accuracy. Stay away fom the HYPED alloy rounds and the extra heavy rounds (in a springer) to keep your springer shooting the best for the longest. I'll also throw in that most of this is irrelivant with a PCP gun. The only hype is the fps a manufacturer boasts their gun will make with these rounds. Yeah, they may make that velosity but for how long? And how accurate? Personally, I'drather have a very accurate gun that lasts a long troublefree time.

Again, just MHO. Let the discussion begin.

Happy Shooting!!!!


CDT recommends not going above 9gr in a .177 and 15 in .22 Steel springer.
It doesn't matter for Gas-Rams.


In all my .177s which ain't a whole lot except for the ruger I keep my pellets under 10 grains and I don't fool with the light pellets the 5 grainers the ruger I will shoot 177 ultras which are 10.9 grains and the gamo rockets which are 9 or10 grainers I think the 22 cals which I have plenty of shoot no higher than 16 grains which some of the heavy jsbs are in some last post I sold a couple of heavy pellets and some pellets that weren't cutting it most I sold were too heavy for what I need I agree I'm not a tuner so I need my springs to last a while now with pcps since there compressed air I assume heavier is better or even with the gas ram but springers that's a no no good luck on what ever you do
