TSS loads will kick the crap out of you- recoil is the issue- guess u can tone down to 1/2 oz in 410? hear they pattern very well at 60 yards - who makes these. Would be cool to have a few boxes of 3 or 3.5 inch. Or can you only buy the tungsten spheres for re loading?
Get yourself a semi auto 28 gauge and a couple cases of winchester steel #6's off rogers sporting goods. I shot that the last weekend of teal season and was killing em dead out to 35-40 yards. If it wasn't for the noise you would have a hard time knowing the gun went off the recoil is so light.
