35 Rem ammo has been spotty for years. With most of the ammo companies working as hard as they can to produce more popular ammo I don't see it getting much better any time soon. I'd say it may become a reloaders only round before long, but I don't even see 35 caliber bullets often. Especially RN needed for the 35 rem.
I picked up a never shot 336 last month. Thought I had done good on it till i went to look for some ammo.... I finally found some leverevolution ammo for it at a local shop. Bought 2 boxes. Nowhere online had any in stock a few weeks ago.
vc1911 --- You've might have been the shooter I talked to at our range last Saturday --- who asked the same question --- Natchez or Palmetto Armory ring a bell?
I solved my .35 Rem ammo issue with a chambering reamer.
My 35 Rem CVA Hunter is now a .358 Winchester. Actually .358 ammo is rarer than finding .35, but it is based on the .308 case which become .358 with one pass of a sizing die.
.35 Remington brass is an odd diameter and selling for a buck a case some places.
