Thanks for the input. I found that also. But haven't been able to find anything else. I'm hoping their as hot and waterproof as the 1075s.
I have a tin of them and don't remember where I even got them.
Temp wise I think there is a good possibility that they are the same as the 1075+. But I am a bit worried about the increased length of the squirt possibly interring with the correct crush of the cap. Most #11 nipple posts are or have tapered structure to them. If the taper causes the cap not to push down all the way onto the nipple it could be a problem. I really would suggest placing the nipple on the post with a capper that allows you to really push with pressure to ensure the cap is tightly seated.
Then again... giving RWS credit they might know exactly what they built. Wish I had some to try - but until this post I didn't know they even existed. If you got them I sure would shoot some.
One thing once installed - the only way you might get them off is to shoot them off or peel them off with the edge of a Knife blade.
