Barrel break in - CCI mini mags, the bullets are much harder lead than really anything else I've seen so I think it did a good job of cleaning out the burs. 2 boxes of CCI's worked well for break in, plus it gave me two plastic boxes for other shells.
Most accurate (50 yards) - Win silver box, under .5" at 50 yards. Soft JHP, but not explosive. On squirell it yielded between a dime and a nickle exit wound. But good penetration.
Used for coyotes - Win Supreme 34gr, black box. If you visually inspect the bullet it looks like the Win 45gr 223 varmint pack bullet, which is highly explosive. The visual difference is the 22 mag version have the front 1/3 cut off. Accuracy is on par with the silver box ammo.
Out of a 5" pistol, to simulate reduced velocity impacts without shooting long range I tested the win supreme black box and the Remington Vmax's. At reduced velocities the Vmax didn't open up, but shot right through the apple I was testing with. The win supremes continued to apple sauce the apples.
Since the win supremes were more accurate than the vmaxes (.5" at 50 for the supremes compared to 1" at 50 for the vmax) and the supremes consistantly opened up at a wider range of velocities, I choose to use the win supreme for coyotes. Or I had anyway until the rumor of a mt lion running around my part started. Now I'm 223 or larger when I'm calling...
Now I have my sportster mag set up for the range. It's wearing a 6-18x50mm target/varmint scope and it's ready for some long range testing. This summer I hope to set some targets up at 100, 150, 200, and possibly beyond and for accuracy, bullet drop, and most importantly, damage analysis. After turkey seasons over, warm calm June and July days, large mowed hay fields, many boxes of ammo, basket of apples (doubles as good deer attractant). Sounds like a relaxing day to me!
It'll be a few months, but I'll post my results.
But back to the subject, the Win supremes get my vote to use on yotes. They're not your fathers 22 mag round, that's for sure. After you do some tests I'm sure you'll be amazed. I still can't believe how much that little bullet does for no more velocity and energy it has compared to a centerfire 22. Winchester made a real winner.
