Well I shot my second ladder today.
Same rifle as before Gamemaster 760 in 30-06
Range was 300 yards
Bullet was Combined Technologies 168 grain SBT

I had 2 distinct two shot clusters. The first two loads and the 5th and 6th load were the two tightest. The other 4 shots were also distinct in where they hit also. It was neat how I could follow them around the grid.

Once my PACT powder dispenser gets here I will be ready to work on finding the loads for two bullets this gun should like.

I must say with the 168 grain and 180 grain bullets the loads 1 and 1.5 grains from max were the tightest.

What does the 760 do with the first two shots from a cold dirty barrel? Don't like to use the term fouled . roger

At this point I don't know because I have not worked up any load for it. I just used a round out of the stash of ammo I have for my M1 Garand. I cleaned the barrel after the last ladder I shot as I like to keep things the same when I compare different bullets.

For what it is worth the first shot a fouling shot was dead center and about 3 inches low of point of aim. However my test loads were no where near this shot. The first two test shots were within 1 1/2 of each other.

What is "shooting a ladder"?

Hey Leo,

Do a search for "Creighton Audette method of load development"

I used this method for years before I ever heard it called Audettes ladder. I would load different powder charges till I got one that would shoot a nice group with 1 grain variation in charge, figuring that this load would shoot well when it was 10 below zero or 80 degrees. Pretty much the same thing the ladder does, only with more of a plan in mind. I have a .220 AI Swift that will put five in a half inch with 45-47 gr H414. Of course it will do .3 with all of them the same charge though.
