Not if the ring set is just made up from individual inaccurately measured rings or mixed up packets. I would at least get the bore size confirmed and then query the rings with the supplier.
I've had personal experience with the Indian made bullet pistons as supplied by Hitchcock's. Two of my WD Enfield's have them (dome top pistons fitted to give a bit more compression). But it was obvious from a friend's experience that the rings were absolute crap/cheese/ licorice. Hitchcock's became aware of this pretty quickly and the pistons are now supplied with European made rings (Italian I believe) and the three Enfield's involved are now running many miles with no problem.

PS Typing at the same time as Ian. Yes those are some strange sizes and tolerances?
