Was looking into helping a friend load some medium pressure 35 remington loads for an older, but not ancient marlin 336 20 inch carbine. I was looking at pressures at http://www.hodgdonreloading.com/data/rifle and was surprised to see that the 35 Rem loads were listed to lower pressure than the 30-30 loads. My guess is that some of the other rifles made in 35 rem are weaker than the 336. I assume that a 336 is at least as strong as an older 94 winchester. The pressure differences are not much but they are there. I want to stay considerably below max since these are not hunting loads, but was curious about the reason for the differences.

If the marlin has microgroove rifling I wonder if jacketed bullets will fair better in that rifling versus cast lead.
