RE: Remington 7600, 35 Whelen
There are only three factory loads available at this time two are from remington, 200 and 250 gr corlokt and the other is from federal, 225 gr tbbc. I am just starting to work a load up for 200 gr bullets. As far as reloading considerations go, the only thing I'm aware of is that you treat a slide action like a lever and you should full length size the cases to ensure reliable feeding of the cartridge. I have not seen a gun yet that only liked factory ammo.
