You'll be money ahead by going with a 20 and TSS.
Money ahead compared to what? Compared to factory 12ga loads?
My statement was based on the fact that:
1. Either of my 20 gauges with TSS will outshoot my 12 gauges with ANY factory load any day of the week;
2. I now have the following 12 gauge turkey guns that I will never use again:
BENELLI SBEII 3.5"
Beretta A400 Extreme 3.5"
Browning A5
Remington 870 Supermag 3.5"
Browning BPS 3.5"
I would have saved myself thousands of dollars in my quest for the perfect turkey gun.
