Hunt Shack Ammo?

[tjen]

First what Nosler load in the 22hornet ammo, is it just the 45gr solid base?

Second I was looking at HSM Ammo with the calhoun bullets in 30, 37, & 42gr bullets. Its mainly for bob cats and coyotes for 30 to 125 yards or so. 37gr or 42gr is there any differance in bullet profile or performance?

So has any used these?
