Reloading for an open sight rifle.

[Redneck 7]

Hello everyone, question that I have and can't find anywhere on Google specifically is when you're reloading for an open sight rifle, do you just use a generic load? Fine tune a load to the .5 grain and see how it shoots at 50 yards? Or 75 or 100? Shooter error can be more of the problem farther out since I don't like shooting sleds.

It's just for my deer gun, I only shoot under 100 yards with it anyways, I'm just running out of factory ammo I stocked up on so time to start pressing some. Looking for some opinions, experiences, load data for a Remington 7600 .243 1:9 1/4 twist with a 22" barrel. Thanks in advance.
