I'm having a little trouble reloading for my contender in 35 Rem, most of my reloading manuals recommend 4064 and H335 but these are for rifle length barrels and burn too slowly in the 14". I've found that 12 grains unique behind a 200 grain LRN is a very accurate load but am only getting 1500fps. I would like to develop a hunting cartridge with the Hornady 200 grain SP in the 2000fps range and i've read that some are having success with reduced loads of 2400 and SR 4759 but these are still "plinking loads" and reporting velocities in the 1600fps range, as far as i can tell no one has really tried to hotrod this cartridge out like the application i am trying for. SR 4759 isnt available anymore but i can find 2400 occasionally.
In a situation like this how do i proceed? should I use the 2400 and the reduced load as a starting point, then work my way up until accuracy drops, or is there another powder I should be considering?
