My Sherman 6.5 max-600 yard ladder/group test

[odoylerules]

Yeah, I am thinking 6.5 what? I notice that part is left out.

It's in the title. "6.5 max" it's a Sherman wildcat, basically a 6.5 saum improved

oh ok I need more coffee I guess I missed that, thanks

I tried a little seating depth test. Purple is .005" off the lands and green is .015" inches off. Both are pretty phenomenal groups for 600 yards and I am extremely happy. It is a lot colder this morning and my velocities got significantly slower, like 20 ft./s slower than yesterday

Thanks for the follow up to your original post. Not everyone does. It helps with the learning process.

I'd try a little more jump, as it seems your rifle likes at least .015" jump. Since you're using Berger bullets I run their seating depth test.

His heading says 6.5Max. , I'm not familiar with the cartridge but I like the numbers.

I'll take it! Who am I kidding? I can't shoot any better than this. Frankly with a 15 power scope at 600 yards, the center cross hair dot takes up the whole 3 inch orange spot. I think I've got a load that I'm sticking with
6.5 Sherman max (saum improved)
21" barrel
Berger 156
64.5 gr N570
3050fps
.219 MOA (yesterday was .3 MOA)

Mr. O'Doyle for the WIN!

The green might be the best if it weren't for shot 9. When I get a flyer like that I check myself first, because the others are all vertically strung

I ran a ladder with N560 and Hammer hunter 131gr pills today.
9,10,11 clustered nicely.
9 was 62.0 gr at 3185fps
10 was 62.5gr at 3192fps
11 was 63.0gr at 3225fps
I'll narrow this down in a few days but I know there's a solid node here

Great results on your testing !
I've got a similar build. Doing some load work
myself. So far I've got good results with 123 Absolute Hammers & 156 Berger's.
Next up is the 131 HH. I'll be interested in
Your results on the 131.
