Predator Big Boy .177 Cal, 13.0 Grains

[KenH]

Has anyone tried the Predator Big Boy .177 Cal, 13.0 Grains pellets?  13 gr seems pretty big for a 177 - do they work very well? 

Here's a link to them at Amazon.com: http://tinyurl.com/4xmjp7u

Thanks for sharing any info.

I just got a can of these but have yet to shoot them.

They'll be awesome from a PCP rifle, but way to heavy for a springer.

too heavy for a nitro piston?

I would be interesting to know if the BC has improved.  A pred. without a parachute would would be great for longer range hunting

mabe the piston could handle it, but the seal wouldn't

if they are to heavy at 13gr
does it have something to do with .177 vs .22?
just asking because there are .22 and .25 springers and nitros out there

to be honest, I'm reading his thread again because I was 2nd guessing my self.  While the springs in a crosman Storm .177 and a Quest .22 are different, all the seals are the same part. 

Originally, I was thinking that a seal trying to hold the additional pressure created by the heavy pellet.  It'll kill your spring though, we know that for sure..lol
