I'd go with the 190 load data to start with.
You can also loosen up on how slow you work up your load. Once you find an accuracy node work around it but you'll shoot out the barrel before you even get a load if you don't watch it. I nearly laughed when 1/2 grain changes on the bottom end were mentioned- I'd go at least 1 until you are familiar with the rifle. Possibly even coarser on the bottom end then. Once you pass the mid charge I'd slow up but 1/10th grain for a cartridge of this size is a fart in the breeze. Benchrest guys with 30 grain powder capacities need to do this. Your rifle can eat over 100 grains of powder.
As to bullets, There is a reason I'm using the hdy 225hpbt in my rifle and not a heavy berger. I load to mag length on a remmy and I'm not single loading a magazine rifle unless I have to. Berger makes good pills and they have their place, but not in a rifle of mine that needs a jump because of freebore. I also use the 190 and 180 hdy interlock in this rifle and they all shoot well at 3.650" oal. with over .200" jump. I didn't measure exactly as I simply do not care. 1.2 - 2/3 moa accuracy no matter the conditions says enough for me.
Great info, thanks.
