RABBIT MAGNUMS FOUND HERE


RAMCAM

Recommended Posts


Thanks Pete! I agree with Deker too. But couldn't it be that this is a problem that's aggravated in FAC springers?

 

Cause most people agree that light or extra heavy pellets increase the possibility of dieseling. Maybe its a series of situations that contribute to the spring fatigue. Including bad maintenance as Deker said..

 

The sad part is that I don't have any friends who use sub 12ft/lb rifles. So all I can speak of is FAC ones.

 

To contradict myself, I never use light pellets in my rifles. The most common .22 I use are two local brands in 18.98 and 21.45 grains. Both perform beautifully and I have had no problems so far. But I service my guns regularly.. maybe thats why!..

 

Either ways, it seems that RAMCAM shouldn't have any problems using the magnums! :-)

Maintainence is indeed the key. Correct lubricant, good seals etc- old leather main seals used to cause problems. With regards the fac springers the principle is the same as a standard sub 12ft/lb airgun. In my opinion and from my experience if a pellet is completely jammed in the breach or barrel then you have the effect of having the accelerating piston creating a buffer of air that will cause piston bounce when no air escapes at the crucial moment BUT if one particlar brand of pellet is heavier or tighter than another but enough pressure is created to get it moving up the "spout" and provided the barrel is clean and undamaged then the effect will not usually be suffient to damage the internals. The same goes for light pellets, the effect will be a pellet that moves slightly faster but again the net effect would not in my opinion cause damage. Firing empty is a whole new ball game and WILL damage your springer as the piston will continue to accelerate and with nothing to slow the escaping air and slow down the piston it will find its own natural stop at full speed as it meets the end of the cylinder.

I know one thing though.... if you think about all this cak instead of what you are aiming at then you are going to miss !

 

Have a good one,

 

Pete.

Lol! Well said! he he!

Thats the thing. Enough pressure will eventually develop to push the pellet forward. But the heavier/tighter the pellet, the more the stress on the spring. Thats the whole thing. Also, if the pellet doesn't start moving at the right pressure, undue stress will be exerted on all the internals. right??

 

The same goes for light pellets, the effect will be a pellet that moves slightly faster but again the net effect would not in my opinion cause damage.

 

Sometimes the pellets are so light that its almost equivalent to dry-firing. And in certain super light pellets made of non-lead material, pellet skirt expansion does not happen at times. This leads to near dry fire situation where the piston does not have enough resistance while firing.. bad news again!

I had a Gamo spectra when I was younger, always used H&N silverpoints in it (the pointed version of the eunjin pellet: HEAVY!!)

I opend it for a chek out last year: everything brandnew inside! :)

Think I shot 3500 silverpoints with it :icon_redface:

Nice groupings at 15 yards :D

Thats cool! What colour did you have? I gifted my brother a bright blue one years ago. I liked the red one, but the store didn't have it in stock then.

 

My bro uses gamo round balls in it.. It was a fun fun plinker!! and super light!

 

The H&N Silver Points are 11.80gr in .177 and 16.90gr in .22 They ain't that heavy. The Rabbit Magnum discussed here is 16.85 in .177 and 30gr in .22. Now thats heavy!
