Carlson's .640 tube...

[mossyoakpro]

I was at my local gunshop today picking up a Carlson's .660 and noticed a Carlson's .640....has anyone tried this tight of a contriction?  If so what shoots good out of it?  I figure #7's, 8's or 9's?

For $28 it may be worth a test drive....

Thanks!!

A fella I know sent me a pic over the weekend of a pattern he shot. He was using the .640 Carlson and 3.5" LB #6s. Let's just say, the setup he's got should be outlawed in the turkey woods.

I used to have an old Carlson's .640. Tried it in a short barreled 870 back in the mid 90s. It did okay with lead 6s at the time but wouldn't come close to a factory RSF.

Hmmmm, maybe it is worth a $28 gamble then....next time I go by there I may pick it up to give a try.

I have a .640 carlsons for my rem guns. It does ok with lead 6. I think it would shot some hevi 7s good. But for most applications it is over-choked. most remingtons seem to like .655-.665. I dont know what gun you have but the benelli-stoeger barrels love the tight choke. I shoot .650 carlsons in a m1 benelli and my friend shoots the .640 carlsons in his m3500. I do around 180-190 with longbeard 3" 5s. He shoots longbeard 3.5" 6s and shot 260s in 10" saturday. Those carlsons are hard to beat for the price and made in good ol USA

I have a bunch of extended hasting chokes left over from my early days.  With a .640 and different brands of shells the main part of the pattern would float around.  On every paper pattern the main group of the pattern would change position with each shot.  I would imagine if you would like to try a .640 I would stick with small shot.
