OK, here's the deal. Went out to the range last weekend with my LR308 and my coworker who is a pro reloader. I'm still working to dial in my LR and he is helping. We shot several different types and brands of ammo looking for the best group. Most were pretty similar in their POI at 100 yards. Until we got to his hand loads. They consistently shot 6 inches higher at 100 yards. I thought they must be moving quite a bit faster, but we ran both the hand loads and factory stuff over the chrony and the hand loads were 180 fps slower than the factory loads. The hand loads were using a 178 gr tipped triple shock vs. the 175 gr fmj or 168 gr jhpbt bullets of the factory ammo.
So, we are completely perplexed at this point and looking for any insight that you guys might have on this situation.
Thanks Jim. We were dumbfounded as to why a fairly wide variety of factory ammo was pretty close in POI but these handloads were all consistently 6" higher. They were repeatable and accurate, but 6" high.
The benefit of hand loading; the result, if repeatable, is just the thing you are looking for. Adjust you cross hairs for bullet impact, reset you turret on the scope to read " 0 " and you now have new DOPE for that round at that set distance. and you can start to calculate how much wind-age and elevation you will need at your other distances. run it up, shoot it and see how your actual #'s compare to your calculated #'s. let the fun begin!
