I am short on funds right now and was just wandering if at all possible can you shoot with just a full choke. I would probably be able to buy another choke if it is really necessary but I was just wandering about the full choke?

Full would probably be all right, but you can a "ventilator" turkey choke made by remington for under $30. It's a great choke.

...fIRST GIVE THE FULL CHOKE A CHANCE,MY FRIENDS 870 SHOOTS TOP NOTCH
WITH REM NITRO MAG,S..HIS IS A TURKEY THUMPER..

i have a ventilator and it works well.

Can you shoot the Hevi shot with the Ventilator or would you suggest otherwise.

Hastings extended choke tube

In my 870 I use an H.S. Undertaker for 20 $.

I also have an UNDERTAKER on my 870 supermag. I shot hevishot
3 1/2" #5 1 7/8 oz. out of it a few days ago. I counted 60 pellets in a 7 1/2" circle at 40 yards. That's good enough for me. I'm going to get out and do some more patterning maybe this weekend. The Remington extra-full choke with the same load put 48 pellets in the same size circle. still good enough but just not as good as the Undertaker.
