every shot from extreme or elite that have to discard or re-usable full plastic ? answer would be appreciated .

I reused the red plastic jackets on the knight LRH several times at the range, but i always used new ones hunting.....

I've reused the red plastics many times but you can tell they don't fit as tight as a new one, as a result you get more blowback. For hunting I make sure i use new ones.

same for me as revpilot. I reuse them on the range, but use new ones for hunting. It does not seem to effect my groups or point of impact.

new disc for every shot

Get the conversion - do away with them.

When hunting - i always use new jackets at the range I re-use them several times before pitching them.

I know a lot of peole do not like the jackets, myself I really do prefer them. In the weather I hunt in there are important as they seal the breech so that moisture can not reach the powder, + they extract quickly and easily roll out of the bolt.

I did try the NFPJ for awhile but there are times that the primer would get stuck in the in the BP and it was difficult to get out.
