I've been doing some research on the RWS Field Line of pellets, which are the ones I'm most familiar with.... Here is a complete listing....

The only one I can see that has a nearly direct version in the H&N lineup is the .25 cal SuperDome which is VERY close to an H&N Baracuda in weight and shape.... The only significant difference is that the largest diameter on the head of the pellet on the H&N has a short parallel section whereas the RWS has quite a sharp edge there.... All the other RWS Field Line pellets are either significantly different in shape or weight to the nearest H&N....
In addition, none of the RWS Sport Line or Basic Line have direct equivalents in the H&N line either.... H&N don't have anything that light in their wadcutter lineups....
RWS pellets may well be made by H&N, but if so, the ones in those three "lines" at least are made to specific RWS designs....
