First, the 6,5mm Creedmore is just a 250-3000.
I have shot a 220 Swift for along time.
I have loaded may different pills 40-45 grain.
When you read a ballistic chart on the Swift.
I am in the plus or minus 3in zone out to 350 yards.
With zero at 200 yards. I have no need for a rangefinder.
When the wind comes in to play. I just shoot something bigger.
Who told you can have just one rifle, think of potato chips.
My rule is one new rifle ever year.
I like the 300 Blackout with 125 grain, which is a wind buster.
This CZ 527 is my carry rifle on the farm.
With the 208-220 gr no noise. Firing pin goes click.
My little Leupold 1X4 does a fine job.
