Tanner,
In my heavy -47, my two favorite loads are
140 Hybrid, 40.8 H4350, CCI 450
130 VLD, 40.25 H4350, CCI 450
This gun doesn't get played with much when it comes to testing a large variety of components. Once I found a load, I locked it down and simply shot it. I've made numerous hits on my 2k yd plate with the Hybrid load, though it runs out of umph around 1800+ yds and I have to add an extra 4 moa to make the hits.
My light -47 get hunted mostly though I did use it for the 2012 24 Hr Sniper Adventure Challenge, where I carried 65 lbs of gear over a 36 mile mountainous course for 28 hours. That load was the 130 VLD, 38.6 Varget and CCI 450.
I've tested, successfully, 100 PT, 123 mk, 127 LRX, 130 VLD/AB, 140 MB/CC/VLD and 142 Matrix VLD.
IMR 8208 has great accuracy but lower velocity with the 100 PT.
The 127 LRX and Varget killed a Montana mulie @ 500 and a large Utah cow elk @ 450 with Varget.
I used the Canadian 142 Matrix VLD and Rel 17, 2917 fps, to kill a spike elk at 950 this past October. I dare not give the load 'cause it was a lot of powder in there. In several of my Rel 17 trials, I discovered the Fed 205m primer out performed my beloved CCI 450 primer.
A sleeper powder was the IMR 4007ssc with the 140 VLD. Hunted it but didn't kill anything. The burn rate is right between Varget and H4350.
You won't find load data with some of these powders so I used 6.5CM or 260 data to extrapolate where I want to start/stop. I then let the rifle tell me where to stop as well as where the accuracy node it. I run pressure ladders, adding .2 gr increments.
Hope this helps.
Alan
