I would like to see some serious research done on the 35W.
I have a couple of my own ideas, as I am planning on getting a couple of 'em, and I like to research as much as I can about them so I know what to expect.
first thing, I think is the H&R QC on chambering. I am getting an impression that H&R chambers on the big side of SAAMI specs. this allows them to save dollar on reamers by being able to sharpen them a couple times if need be. If you get a rifle that has been chambered by a new reamer, it will be on the big side.
second: ammo manufacturers are finding ways to save a buck here and there.
think about this: if you can save 1% per cartridge on brass, and you make 1 million cartridges a month, you will save approx. 14,000,000 grains of brass. that is one ton of brass.... at over $3/lb that is a savings of over $6000/mo.
now if YOU were running a business, you would look at that $6000 as your bonus money! $72000/yr is nothing to sneeze at when you deal with tiny margins.
and there seems to be agreement that cartridges are being made on the small side of SAAMI specs.
and in the head area, even LESS than SAAMI on some!
so, Max chamber, Min (or less) cartridge on a sloping, small shouldered round, and you end up with stacked tolerance error.
proper fireforming should correct this, as well as proper handloading techniques, but SUCKS for factory cartridges if you have a sloppy chamber.
there is a reason Rimmed came before Rimless
