Looking at buying a 28 gauge for bird and turkey hunting. Mostly shoot pumps for their reliability. Was looking at the cz and the Browning. Would like some opinions if possible. The only drawbacks I see is the cz is a aluminum frame and the Browning is made on a 20 gauge frame. Have always wanted a side by side and have been looking at the cz bobwhite and the sharptail but have heard their patterns can be off quite a bit between barrels. Thanks in advance.
