Hornady 68 or 77 grain HPBT Match bullets with Reloader 15 would be a good start. Varget will work well with those bullets as well. Though I give a slight edge to the RL15. I have had outstanding results with both in a 1 in 9 Savage Bolt action.
For a pretty darn accurate load to 400 or so yards/meters a 55 grain Hornady V-Max with H-335 has been a sub MOA load in 8 rifles that I have tested them in. 6 were various AR platforms that were around 1 inch for 3 shots. One single shot TC Encore gave a 3/4 inch 5 shot group. My Savage bull barrel will put them in the same hole.
No matter how many times you do it and nothing happens it only takes something going wrong one time to kill you.
