Both were shot at 40 yards with a Rem. Super Mag 23" barrel and .660 Ventilator choke. The Win. was a 2 1/4oz #5, the Nitro was a 2 1/4oz 4x5x7. the first picture is the Win.

WINCHESTER


NITRO

I thought the Remington Ventilator choke was a .655? From what i' ve read at Remingtons web sight they saids that the Ventilator choke did not pattern well with there Hevi Shot..

It may be a .655, the mike I used actually called it in between .655 and .660. I was surprised to see this big of difference. I had these papers taped to a large piece of cardboard, you can really tell the difference when you look at the backside of the cardboard The Nitro pattern was a whole lot tighter.

Strut,
Just curious, was it a 3' ' or 3 1/2' ' .

Both were 3 1/2"

You should give the Rhino choke a try for the Nitro ammo. I was really amazed at what it did out of my 3.5" Browning BPS.

Yeah the Rhino is the choke Nitro recommends , I talked to them and they thought the Ventilator would do a pretty good job, And I better quit here, the wife don' t know what these Nitro shells cost yet and to add a Rhino choke might be kind of asking for it LOL.

I know what you mean about the wife, I do the same thing! LOL

Has anyone ever shot these Nitro' s thru a Rhino choke?

Strut, check out the post What' s your favorite turkey choke tube? and go down to the post by Tomahog. He has used the Rhino choke and Nitro ammo. He apparently likes it a whole bunch!
