Re: Please analyze my ladder test

Thanks everyone, and abinok for the chrony offer. I DEFINITELY wouldn't go over book max without one! I'll either borrow a buddy's or I'm going to bid on a used one today and see if I get it.

I thought 14-17 as well, this one was pretty clear-cut...what an ammo saving tool! I'll probably load 4 at the charges for 15-17 and also bump up to 74gr and try that...and stop there no matter what.

Yes, I thought those last shots were grouped pretty well for a totally factory gun and someone who probably shoots less well with a scope than most of you do [img]/ubbthreads/images/graemlins/laugh.gif[/img]

Re: Please analyze my ladder test

Newby here, please go easy. This (ladder) test is new to me. You shoot all incremental loaads into one target and look for the sweet spot, or "group"? I've tested incremental loads of , say, 3 rounds each and looked for the broad increments that group well. This looks like a fine shortcut to the same goal. Do I have it?
Thanks

Re: Please analyze my ladder test

I'm not the most experienced myself, but....

The test shows the nodes in the harmonics where the gun shoots well. Theoretically, a .3 grain change should not move the shot very much at 300 yds. Yet on the target you see many of them shifted impact by several inches. This must be due to some other influence than just the charge (barrel harmonics etc).

In a couple spots, namely shots 13-17 on my target, the shots do group very close together, indicating a node where the shots behave as they should. My understanding is that on these nodes, the gun will also be more accurate than at any charge outside of a node as the harmonics are good.

I'm actually going to shoot the groups to verify the results of the ladder test within the next couple days and I will post results when I have them.

Re: Please analyze my ladder test

I do believe I understand. This is based on barrel vibration and the resulting shot dispersion, same being least when the muzzle is at the null point. (Much of what I know I learned from Harold Vaughn (RIP) in "Rifle Accuracy Facts".) What a great tool!
