You might have seen my other thread re my Omark / Sportco 308 rifle. I've been fiddling around with the rifle and the new Bushnell AR 4.5-18x40 scope and today took the combo out to 750y for the first time. Indeed this is the furthest I've ever shot save for a couple of attempts at fullbore target shooting when I was a teenager.
Wind was pretty mild, only about 7kph at about 45 degree angle so I wound on just one moa of windage and let two five-shot groups go from the prone with the bipod...
]
As you can see I had wound on about two moa too much elevation. Save for that the groups were pretty good I thought. About 4 and 6 inches vertical spread, with the left group coming in about 8 inches and the right one with the flier that I pulled over a foot horizontally.
Load details are W-W brass, CCI primer, 168g Amax (these are branded Zmax but the same thing I believe) with 44.0g H4895. Muzzle velocity is 2750fps.
For those interested, I am very happy with this scope for what is a relatively cheap made-in-China item. The optics were such that on this dull overcast day I could very clearly discern the middle white diamond in the aiming point. Adjustments for come-ups seem very consistent out to 600y, however I'm a little unsure what caused my overadjustment today. I'll do more work to confirm these things. The scope certainly has held zero no probs over 150 rounds fired so far.
Anyway for what this outfit owes me which is only a few hundred dollars counting the scope I could not be more satisfied. The rifle was most likely built around the same time I was born and there's some satisfaction in that too.
