A good day shooting leaves me with some serious ladder test questions.

[QUOTE="royinidaho, post: 98992, member: 2011"] [b]Re: A good day shooting leaves me with some serious ladder test questi[/b] Nah, you're not smoking crack [img]/ubbthreads/images/graemlins/crazy.gif[/img] [img]/ubbthreads/images/graemlins/crazy.gif[/img] I took your thoughts and went spinning off on my own. Here's what I came up with. Just to let you you're not the only one who thinks hard about these things. [img]/ubbthreads/images/graemlins/grin.gif[/img] I picked the consecutive shots that show a definite trend in your above Pics. Shots 1 through 4 do what is expected, a nice vertical rise w/velocity (except for #1 which I'll check off as a cold/maybe clean barrel). But nevertheless a vertical string. Then shots 4, 5 & 6 produce a nice horizonal string. Hmmmmn Shots 8, 9 & 10 produced a triangle, I'd call that a group. Look at the velocity steps between 4/5/6 and 8/9/10. About 12 FPS compared to closer to 30 FPS per step change. But still nevertheless a 'group' maybe about 2 1/4". Then look at shots 13 thru 16. Back to horizonal string again. Considering the shot placement along with the velocity trends gets a little more interesting. Seeing as it is your brother that's taking the punishment, I'd consider doin' it again. But as suggested above, start at Load #10 and go up. You can always stop when the loads get too hot. Before you shot them though, I'd consider spinning the loads to look for out of roundness. A spinner would be useful but not absolutely necessary. Just roll them on a flat surface and if any are out of round you'll see it. (Just a tho't). Here's my prediction. I'm going way out on a limb here. Credibility gonna go down the tubes. [img]/ubbthreads/images/graemlins/blush.gif[/img] [img]/ubbthreads/images/graemlins/frown.gif[/img] As testing is continued you will continue to see alternating patterns of vertical then horizonal stringing. There will be another vertical and horizonal pattern above the shots 13 through 15 sequence. Then, finally 1/2 way between the next vertical and horizonal pattern's is where it will shoot the best symetrical groups. This may be all out of wack but it's a pattern that I've seen too many times to dissregard. Good luck and have fun. PS: I'd consider cutting the powder change steps at least by 50%.
