[QUOTE="Fiftydriver, post: 171362, member: 10"] Tested this load at longer ranges today, was a bit windy and was shooting up through a deep canyon so the wind did get to the bullets a bit. At 665 yards, the first two landed 2" apart, third shot dropped 6"??? Think it was me. At 1005 yards first three shots went into 9" with two only 3" apart. Four shot opened things up to 11" and fifth shot dropped well out of the group, about 8" low of rest of shots. I am sure barrel heat was the problem here. Still first three were very impressive. I did not let the barrel cool, just shot five as quickly as possible. Under 1 moa for the first three at 1000 yards is plenty with a 9 lb rifle in my opinion. Wind is a kicker, not used to holding that far into the wind. Also shot the 338 AM with 265 gr AT RBBT. At 750 yards, put three in a 3" group. At 1005, four shots measured 12" horizontal by 5" vertical. Wind was 15 to 25 mph from my 8 o'clock position, very variable so I am pretty happy with that. In calm conditions I am sure that 1/2 moa would not be much challange for those first three. Got to get some calm time to get them fine tuned for hunting!!! They are pretty darn close right now but just need one good calm morning to varify horizontal zero and their ready for field work. Horizontally, they are right on the money. Kirby Allen(50) [/QUOTE]
