Rem. 700 ADL 30-06, factory 22 1/2" sporter barrel, Win brass, 10 twist, CCI 200 primers, 3k elevation, 70*f, 15% RH,
with 208 AMAXs jumping .010", 3.766" with comparator, 3.52+/- COAL from tip:
55g R17 - 2720 fps. Horrible accuracy. 4" vertical at 200 meters. Tested several times. Probably would've shot better at lower velocities. Strong ejector marks, but primer's look good still, etc. Up around 56g, primer pockets would loosen. I may try 52-54 again, but lots of unused space in cartridge.
H4350 - best accuracy so far from this gun. 210g Bergers kissing, 3.776" from comp. I lost my paper and can't remember the charge weight but I think it was around 55g, iirc.
.3 MOA @100m with me on the gun with bipod/rear bag from bench. Loaded for a cow elk tag a couple years ago. Got on several bulls, but never did get on a cow.
4831sc -3K' elevation, 93*f, 208g AMAX
60g -2600fps - testing now, but back under MOA ~0.8 or so at 200m. no pressure at all, but very close to max fill.
I have 20 or so loaded up for further testing. Have a couple compressed 60.5 rounds loaded also waiting for wind to die (springtime in AZ
I strongly dislike wind)... Accuracy nodes appeared to be at 58 and 60.
58 showed single digit ES and almost zero vertical. Hopefully 60 will repeat, but with higher velocity. If not, maybe 60.5, but can't any more in the cartridge.
Wish I could get VV N560 reliably locally.
Overall, I may give R-17 a retry, but I feel it's too fast for cartridge- perfect in .308, but a tad fast for '06 (IMHO). I also may try h4350 again just for kicks once I get 4831sc sorted. I may have her re-barreled by then though. We'll see...
Hope it helps.
