I just tried a few months ago with barnes 62ttsx and it worked great, till about 250 yards where it began keyholing targets. I have a target I set out at 500yards and the 62 was perfectly vertical when it hit. very nice bullet hole in my target but that thing turns into a shuriken once past 200 or so.
i guess all barrels are different because ive had good luck with an Oly arms K8 target match heavy stainless 5.56 with 1:9". Just this weekend my cousin and I shot several moa groups at 400 lasered yards. Im shooting 69 SMK's and hes shooting 70 berger VLD's. We finished up on a 732 yard lasered target just for kicks. He missed every shot due to double dialing his windage. I had three shots left and made good on one. Wind was gusty @ 20 knots, but the swirling wind was the challenge. My final shot I dialed back to 0 wind and waited for it to lay then squeezed off. probably some luck, but Ill take it. Were gonna try some more in a couple of weeks maybe ill have a good report! Be glad when my grendel is done, I expect much better from it. BTW my cousins gun is a DPMS special bull 24" (heavy sucka!) 1:9" in .223 rem . Edit: Im not disputing what you guys are saying, just telling my experience.
