Guns, Dogs and Blades QnA

So question for the esteemed members here: I have my dad’s 1949 Remington 722 in .257 Roberts. It is equipped with a Redfield peep sight and I think I will stick with that. Since I have a Remington 700 Mountain Rifle also in .257 Roberts, I have the dies and everything to work up some loads for it. The question comes to what projectile should I use. Since most factory ammo was predominately soft point round nose bullets (Hornady), should I stick with more period correct bullet choices or use the modern offerings (I have Partitions, Sierra Pro-Hunters, Speer Grand Slams, Hornady SST, etc). Curious what your thoughts are as I plan on taking it to the woods a bit this coming fall.
Experiment. :D I made some 30=30 Winchester with spire point boat tails for my Marlin lever gun :D . One in the chamber and one in the mag for safety reasons. Factory loads weren't even close accuracy-wise.
