[QUOTE="ajhardle, post: 833351, member: 49861"] First off, thanks for the article. I frequently need a push to get the gears in my head moving. Now BountyHunter, I'm sure I don't have to tell, but smaller angular groups at longer range is most likely an issue of gyroscopic stability that may exaggerate the pitch and yawing motions, or maybe orbital gyrations? I'm not a scientist (professionally) but it seems to fit. It would be interesting to perform this test with my 75gr Amax load in a 9 twist at 2650 fps. I would think the motions would have a greater affect on drag with the much longer bullet. As for the tighter groups at longer ranges, I will setup multiple targets out to 300yards, and shoot them all simultaneously. But, that will have to wait, because right now, they shoot great at 100 yards. I guess 90 degrees at 4300 ft is enough to properly stabilize them. When I started developing the load in 30 degree temperature, it was not. To me, that was enough evidence to confirm, but I might be fooling myself? [/QUOTE]
