Magazine or magazine mod for 35 remington

Got my barrel on for my 35 rem build. Headpsaced fine and mounted into the stock after fitting the barrel. Cycled some cartridges through to test extraction after I installe the enhanced extractor kit (works like a charm). Only thing i noticed is with the 35 rem cartridges they seem to point nose up quite a bit and it seems like some need a little help clambering. Rifle was originally a 243 so using the detachable mag for that. Is there a better mag or a modification I can do to level out the primer side of the cartridges?
