If you wish to go long range Varget powder may be a bit fast and reach pressure limits prior to achieving a good velocity. The case capacity is about 60 grains of something like RL-22 or 4831. Try 55 or so grains of either and the CCI-200 and work up from there. The RL-22 may will end up producing the most accurate loads.
I've never had bad shooting with any of the sierras but the bc of the game king hollow point is pretty poor.... Nosler 130 Ballistic tips and Accubonds are great. For some reason we have stuck with the 140 Hornady BTSP interlock.
For reaching out and touching something you'll want as much velocity as is reasonable out of that cartridge. At least 3000 fps. 3200 is even better and some combinations of bullet, powder, chamber and bore will do it and with good case life.
As said above in most posts, don't mess with the gun but improve the load and the scope.
I hate to recommend a less expensive (read cheap) scope. I've done that too many times and have been sorry each time. One of the most reasonable scopes with good clicks and for shooting in day light is the Super Sniper. They can be had for about 250 bucks in the used market or 300 bucks new. The 10X is sufficient. The 16X is noticeably worse in dim light at least with my eyes. The fixed power may be a spot of bother for close shots but in my experience they are rock solid.
Keep at it and soon that 500yd buck will be in the freezer and the rack on the wall.;)
I may be the slowest guy on the mountain . . . . but . . . . I'm on the mountain!
if you are looking for an inexpensive scope look to the super sniper. remember these are 30 mil tube, i have 1 and it holds its zero very well. i just order the new bushnell 5x15x40 tactical new they are 329.oo. i have heard very good things about these, if this is to much money then look to the bushnell 10x40 new in the box they are 179.99. make sure that you have them in good rings and bases. then you can save for a mark 4, nightforce,s&b or Ior.
My brother had a 710 in 300 win mag from walmart. It would shoot very good with hand loads. It wouldn't shoot the vld bullets very good but it would shoot the reg. berger 168gr hpbt very good out to 800 yards very accurate. After he got the hang of shooting out there he built his own savage. I would say leave it alone and work on your loads, practice alot, learn the wind, after a while you'll know what you want to try next.
sounds like a fun gun to shoot. My experience with range finders is dont get the cheaper models, I have 2 bushnells that didnt cut it and now have one that wil range out as far as my 300rum will shoot. Have fun with the gun and save for a good range finder. Remember that what ever they are rated for cut that in half and you can figure that as a consistant range yardage, expect for the higher end models that will range out to their rated yardage, just what I have found. I have a bushnell 1000 (JUNK), Yardage pro 800 (NOT BAD), and now a newcon2000 pro (Amazing).
