Invert Mini cold weather barrel breaks

Hi

So I have an invert mini, I bought it set it to around 300 psi out of the box and it worked great all spring and summer.

Seems in the winter I get allot of barrel breaks, more with bad paint ie. heat formula 13, zephyr zxs ect. not as bad with polar ice or even RP premium but it still happens.

I'm going into my second winter with this gun and the problem went away for the summer. Anyone have similar problems? Seems to be 35 40 deg. below that I have the problem, doesn't look like chops, seems to be mostly barrel breaks no paint in the feed neck ect.

I'm playing on the 28th and I'd like to at least try to solve if not reduce the problem.

I have ideas:
1. open faced bolt may be imparting to much direct pressure on the center of the ball and due to cold there is some change in friction on the outside.

Is the shocktech mini bolt a venturi?

2. Long barrels, I have a 18" and 16" tip for my freak, I know the longer the barrel the more breaks in the cold has been true with all paintball guns for a long time.

I ordered a short WWA freak tip the crown point type

3. There is some other mini specific circumstance I don't understand?

well, paint is more brittle in colder temperatures. what bore insert are you using? i would suggest going overbore (.689+) during the winter to prevent breaks, or use winter paint.

I think I was using .679 aluminum insert on the 17th (19deg F).

I had Polar Ice it worked better, unfortunately I tried to motor through a case of summer paint first, and got the barrel all fouled up.

I'm going to go with all Polar Ice on the 28th.

Thanks,
Moses
