Cold weather effect paint shell?

Hey guys, quick question...

My buddies and I go out and throw paint every Monday in a wooded field behind my neighborhood. This past Monday was the coldest one we've had yet. The temperature hangin' somewhere around the low/mid 40's.
I recently bought a Tippmann A-5 w/responce trigger and LAPCO BigShot 12" barrel. The previous 2 Mondays before this last, I had no problem with chopping balls with that set-up. The temperature then somewhere around the 60's. This last Monday, I chopped 3 in one day of play ( I actually chopped more, but the rest were due to the residue of the initial chop in the barrel). None of these chops were in the Cyclone Feed, but rather specific to inside the barrel. I use medium bore PMI .689 paintballs. They're decent paintballs, Ive used them before with approval.
My question is, will colder weather make the shell of the paintball more brittle, in turn, making the ball shatter when being fired? I know colder weather will make them shrink, but does it make them more brittle?

In a word, yes.
You aren't really chopping balls, as that's what happens when a ball isn't fully in the breech so the bolt "chops" it 'cause it only pushes part of the ball along the barrel. You are simply breaking the ball in the gun.
The temperature definitely has an effect on the fragility of a paintball; most decent manufacturers make a "summer" ball and a "winter" ball to allow for this. Old paint hanging around at the moment could well be summer grade, but any new batches coming into the northern hemisphere from now should be winter grade.

Yeah, good point on the breaking vs. chopping thing. Makes sense.

Im really hoping its weather related, and I feel that it is...

I had no idea that there were different grade balls per season. Thanks.

Maybe I should spend the extra $5.99 for the better ball. Probably wouldn't hurt to turn the velocity down a bit as well.
