Those HW 7's are one heck of a load for sure. Have you had a chance to pattern the Ithaca yet?
for turkeys not yet
But ... I've run about 250 rounds of steel shot through it (with the waterfowl chokes he made me )for waterfowl ...killed all kinds pintails , ducks etc ..the gun is a beast ...shoots dead on with some serious power
I'm going to polish out the barrel and get it ready for turkey season
Sumtoy's waterfowl chokes really work well. My son and I have several in our 12 gauges, they throw great patterns. I have been using a nef/h&r factory extended steel full choke i found at a gunshow that was new in the package in the 10 gauge.If i remember right, I think I measured it at around .750 I.D. Shoots lights out with estate bb loads. Picked up another case of Win 10 gauge steel before the prices shot up, glad i did. Holy smokes it went up about $100 more a case in less than a year! Probably going to get a semi auto 10 eventually, I love the Bps, but the forend is a long reach, even though i have long arms, especially so when wearing bulky cold weather clothes.
