I'm getting close to the end of my stash of older CVA#11 hot flash caps so I recently bought some Nobel 1075's to try out. I tried them out during my last 2 outings and found that they don't fit over the nipple very well, in fact they are way too tight compared to all the other #11's I've tried. One of them took 4 hammer strikes to finally seat and fire. The nipple is brand new and works fine with the CVA caps but out of a dozen 1075's tried, only one of them went off on the first try. I know I can file the nipple a bit and make it work but it seems these caps are closer to a #10 size than #11.Has anyone else noticed this?

I have used a ton of these 1075's and have never noticed a problem fitting on the nipple - and I use all kinds of nipples. They are tight I will grant you that as I have to pry them off. So I guess I am of no help.

Yes they are a tighter fit. I was told they are just a hair more narrow then a standard #11 cap. Perhaps the 1075 is an indication of that. Could they have been indicating .1075 VS .11?? I am not sure. Although I do find they fit the Green Mountain and T/C stainless steel nipples fine and seem to fire every time.

They fire every time for me. The CCA magnums I can pry off with finger nails where I have to use a pocket knife to remove the 1075's. No misfires with either brand.

Used them from back before inlines never had a problem. You mmight consider puting a leather strip over the threads and puting the nipple in the drill and taking a file and very careful not to go to far turn the nipple down, just a bit, it may be a bit oversized. Lee

Thanks for the replies.

Lee,
That is the technique I use after a few range sessions to remove any swelling/peening in the nipple from firing. I just wanted to find out if anyone else had experienced this difference. I will use the file to adjust the diameter just enough to get it to fit on all the way but not too loose. Thanks foir all the help.

I have a couple White U-M'S that I cannot use the noble caps, they fit too tight.
Cannot get them on correctly,on several other Whites they fit fine

1075 does mean 10 3/4, not quite a #11.

They are very snug on my T/C Renegade nipple, but I like them that way. When I load it, I VERY carefully lower the hammer onto the cap and press the hammer to seat the cap on the nipple. I have to pry it off with akey or a knife. I don't reuse them.

Anyway, best caps out there IMO.
