Difference in compression.

These bullets are 30-1 recovered at the 300yard berm fired on two different days with the same charge of powder .OE 1.5 90gns. The only difference was 60 tho more compression on the left one .the cases were dirty and some were really full of fouling with the right load and the left they were cleaner and more consistantly, fouled .
It is interesting to me how much difference 60tho compression made with this load .

How is the accuracy difference between the two?

the vertical was about the same, The wind was tougher today but my hold was a lot more consistant today ,and I had my sight setting.
at 300 you have to take your head off the stock to ty to find the bullet strike , . the load shot 12 min lower than my standard load so I was shooting over the berm for awhile , spotting for ones self up close is the pits, but so far it is running about 2 min or less at 300 . the load appears good but there are some things I aint happy about yet,However,the extra 60 tho compression stopped the paper stuck on the bases.. it seems to be lot hotter powder in large cases , been using it in the weenie gun and the 44 with not near the differences that are showing with the big case,

When I first shot some of it, when you really stepped on the 1.5 it seemed to smooth out in the 45-70.
I'm curious to see how it works in the 44 2.4 when we get those guns put together.
