Barrel Cooling Fans?

"Slow-motion of a 147gr blowing up, every first-round from a cool rifle this happened, but the rest were sub 1/2 MOA at distance and at 100... the shooter was a cool customer, we just called them a foul ball, but this is getting crazy the number of 147s not making it to the target."

Only/always the 147's?

My Tikka loves them, even more than the lighter weight ELD's.

Always thought lighter bullets were more prone to self destruction.

Maybe a production problem??

I think it is a design issue.

147s aren’t light weight for 6.5CM. I shoot 130s and many people shoot 123s.

Here ya go. Like I said, I use it doing precision work especially when sighting in. I’ll shoot a string, toss it in the bore, do my dope book and paperwork, continue shooting. You can definitely tell a temp difference of the air exiting the bore after a few minutes of running it.

Is a water jacket option available?

Probably come with a complimentary stuffed Jackalope.😁

Exactly.

If he had said this was happening with 120 grain or such bullets I would not have been so surprised.

Or a Lewis gun shroud.

I've never given a rifle barrel an even break, let alone let one cool down.

Ok, passing on second hand information which I don’t like doing. It’s my understanding that while they do aide in cooling, not much more than normal radiation. None of my .mil peeps use them. When I asked about them, I was told they just open the bolt and set the rifle on the butt so the heat easily escapes the raised bore.

I believe the issue with 147's blowing up was limited to one batch.
