Wow, as a boy from Saskatchewan, I can tell you our bucks would have NO PROBLEM scaling that wall of snow....
But I'd hate to have to drag one UP that wall!
I have a 280gr 0.360" mould that has been HP'd and should drop a 235-240gr bullet.
in my 357, I hope to push that to about 1600fps, and if cast soft, should be an awesome bullet for bush hunting.
First, from the picture, the "Ring" is far to high up the case.
Look farther down, where the colour changes about 1/4" above the base, THAT is where the brass stretches and separates
Then you post THIS:
Now, WHY would you full size NEW brass? New brass is already at the minimum most times...
When using a ballistics calculator, remember to include your two shot group size into the calculation.
in other words, when you see the number for 100 yd trajectory, ADD 1/2 your group size.
So, if you have a 2MOA rifle, you would add 1" at the 100 yd range, 2 inches at the 200 yds and so on...
