You should have seen the groups these rifles shot before we both switched stocks! With FACTORY ammo!!

I bedded my Ruger with the Boyd's stock

Barrel harmonics may have been just right for the factory ammo. Sometimes it takes considerable load tuning or rifle tweaking to get what came from the factory, but on hunting rifles, many people would give up slightly tighter groups for the POI consistency of free-floated barrels. You just need to find the best combination of consistency and grouping ability to meet your needs.
factory loads tend to be geared toward the OCW so they will shoot in almost any gun well.

another thing you should consider is action screw torque, my CZ's are notorious for demanding the action screws be torqued to their liking, and each is different. Did not think my Savages were that picky but came across this

I think Taylorce is a little off on his pick, I say the 52.8 grns of H4350 is exactly where I'd start.
52.8 grains was a good group as well but the 53.3 was the smallest that he posted. In the 52.8 grain his group was probably thrown open by his trigger squeeze on that particular group. Plus I'll take a little vertical stringing over horizontal if I have my choice. 53.3 should give a little more speed over 52.8 and I'll let my groups open up a little on a hunting rifle for the increase in velocity. If it was a bench rifle vs. what it actually is then I would take accuracy over the speed anyday. However in hunting situations the 53.3 grain group is as good as you'll ever need out of a .270 rifle.
Plus if it was my rifle I'd find powders in the burn rate range of I4831 or H4831 as those are really the best powders I've ever used for the .270 in the 130 grain bullet range. So for powders in the .270 I'd try RL-19, N160, along with the 4831 powders. So far I4831 is my go to powder in my current .270 as it has been giving the best accuracy and speed. The .270 and 4831 go together like PB&J and I've never found a person who reloads the .270 that couldn't get one of those powders to work. Just don't think the powders interchange as I4831 is a little bulkier than H4831.

if it is just meant to be a meat hunter then I would go from 53.9 to 54.2 in .1 increments to see if they all group in the same area. If they do then load up 54.1s and you have plenty of room for error in loads, temps, and range calling and plenty of accuracy out to 250 or 300 for a 3 inch kill zone animal in my opinion

My favorite (most accurate) load in my 270 (Sako Lightweight Hunter) is 59 grains of H4831sc, the 130 grain Nosler Ballistic Tips, and CCI Benchrest primers. My present cases are Remington with a switch to Norma soon. The cases are fully prepped. Don't get me to lying about group sizes, since I haven't measured them in years, but it shoots nice round groups of less than 1 inch, but not less than 3/4 inch.
