heavy pellets

[hw97k 36]

ive read that too aheavy pellet will damage a spring in a spring gun,whats the best limit to go to in a .177 .just fancied a bit more whack with it,cheers.

I've heard that too, mate and I've no idea where it came from but it's crap.

 

My 90 shot very well with Baracudas when it had it's .177 barrel but in general springers don't shoot so good with heavy pellet as the power tends to drop off as the weight goes up, not such a problem with .177 though.

 

Cheers.

10.5 grain pellets are ok to use in a 177 the problem arises when you fire 21grains + from a 12fpe gun.I found that 8.5 JSB's were as hard hitting as most other pellets from a springer.Crosman Premiers and Bisley magnum (H&N Baracuda)are the most accurate heavweights.The crossman pellets are the ones in the cardboard boxes mind not the tins.There is a difference and it shows in the balistic efficiency of the real premiers.Some 177 springers need to be retuned to stay at 11+fpe with heavy pellets,just make sure you keep on the legal side if you do this.As when you go back to light pellets you will be way over.

thinking of using something like a 10 grain jsb in my tx would it be up to the job ,im using 8,4 aas at the moment so do you think its worth it or not thanks

That last bits not really good advice....

 

The reason is spring powered airguns loose efficiency as the weight of the pellet goes up so for example.... A .22 shooting at 11ft-lbs with a 14 grain pellet will drop to around 9 with a 21 grain Baracuda so if the gun's 'tuned' back up with the heavy pellet, it'll be over with a lighter one.

I am no expert but, I used crosman premier ultra magnum (10.5g) in my Lightning xl. They hit nearly 2 inches below target at 20mts. Avoid if possible

 

I will post some images to see how they perform tomorrow if possible..

The point of impact will change more often than not when you change ammo, mate, even with pellets of around the same weight. You'll nearly always have to re-zero your scope after a pellet swap.

 

It's how they group that's important. Give them another go and see what the accuracy's like If they don't group well from your gun then try something else.

 

Good luck!!

 

Cheers.
