I will be putting laminations on some bridger 3s. What is best? Inside, outside or both?

I just put lams on outside. Both probably wouldn't hurt.

neither

I trap public ground with quite a few bird hunters in the area. Most of my traps are 550s and I feel ok about them but not so much the 3s unless I do something to the jaws.

oh....if you add lams I think you need to 4 coil also but I'm not 100% on that

Inside laminations are better then outside.
Look at It this way picture a V and that represents the trap jaws. When closed the deepest part of the V is the tightest same goes for the trap jaws when closed. It may not be much but It will be tighter.

Round.

BMP's showed that inside out did the least damage . But honestly unless your live marketing ,doing extended checks or just wanna have some blinged out traps no real need for both.

Well he's just trying to do the right thing when dealing with domestics. It can't hurt In the long run.

I live trapped for 12 years In the south and It did help with cutting down on injuries. And we always checked early and some times even twice. You didn't what any $100.00 fox to be rejected for any reasons.

I heard a well known trapper of the live market variety say that the inside helps better the the outside.

The inside hits the paw first.. Is the reason..

I put mine on the outside also. Really helps with the holding power without any damage.
