the bullet is overheating

[Pappabear]

When you say it’s overheating, what does that mean?

Have you fixed this problem yet? I also have the problem that the bullet is overheating but I really don't know how to fix it.

I stopped using the AAC powder. I've gone to subbing in Vihta Vhouri N135 instead. I bought some plain jane FMJ 62 gr bullets to load with the AAC powder... loaded very mildly to allow for the random pressure spikes.

How are the bullets performing without AAC powder on board?

I've had the bullets shoot well with AAC powder, but the velocity was too great for gas gun function. I've also had them shoot fine with VV N135 powder.
