I am considering buying some FMJ's for an upcoming bear hunt this September cause I want to shoot a heavier shaft.

It appears that the nock cannot be removed or rotated in the shaft. In other words, it comes from the factory glued-in?

Is this true?

If so, what is the correct method of removed an insert from an FMJ?

They are X nocks. They are removeable and replaceable and easily rotated with the nock tool.

This is correct

OK, thanks!!They seemed overly snug when I looked at them in the store.

They are very snug. You need tool to turn most of them. They don't rotate on the string very well they are so tight.

Thanks again.

Exactly Correct! Same adjustability as G-nocks or Super nocks just a different size.

I shoot this arrow (340) at 29.5 inches and 65 lbs and I think it is the best arrow I have ever shot. But, it is not fast. I only shoot this arrow with a 100 grain point at about 260 fps because it is 11.1 grains per inch. This gives me very good kinetics, a quiet delivery and very accurate. In the Archery Shop in Victoria is a hog I made a head shot on with a FMJ. It went through the skull and penetrated the chest cavity about 5 inches. It is very consistent arrow to arrow in spine, weight, and straightnes and can be bought one at a time. They are expensive however at about $11 a piece, but when you can shoot multiple animals with the same arrow it all works out.

+1, and the TIGHTNESS is a GOOD thing not a bad one....

Most Definitely! Loose nocks or those easily moved would Not be a good thing.
