I"m setting up a 870 Express 12 ga. for the spring hunt.

Tons on choke choices and quite honestly, it's confusing to a rookie like me. Any thoughts on which of the above? Any other suggestions on the load choke combo?

Thanks in advance.

IMHO you can't go wrong with the jellyhead. Great choke. I would go with the 665. It's better for high density loads. As far as the load, Nitro has done great for me! A little Pricey but a great load. Good luck

If you generally go with a smaller shot size, (#6's), the .660 might work better. The .665 will generally work better with larger shot sizes. I usually shoot lead and use a .665 in my BPS. I get as good or better patterns with #4' 2 oz. loads as with the #6 1 3/4 oz. Too tight a choke can blow your patterns.

Thanks Guys.

I measured the standard Full which came with the gun and it's .670. Am I gaining much with .665 and the extension? Perhaps the .02 is a difference maker.

with all the chokes out it still not an exact science. the barrel is still a big variable. most of the time extended tubes work better because they provide a more gradual constriction of the shot string. and some have a provision to pull the wad back. your factory tube might pattern best and if you don't have either sights or optics on your gun and it isn't patterning where the the bead lines up then the tighter the pattern is the more chance you have of missing, especially at close range. sight in and pattern first then work on the tube.

The Nitro 4x5x7's and a .660 work EXCEPTIONALLY well for me. I'm shooting an Extrema though, but this combo would be a great place to start.

I shoot a jellyhead .665 with hevi shot magnum blend, and it patterns great. $20 for a box of five is the only drawback, but I think it is worth it

I agree. Great combo!

I believe it depends on the ammo you plan on shooting. Coppper/lead likes a tight choke and heavy blends like a little more open choke...

Thanks, If I shoot Heavi 13 for example, perhaps the .670 stock full will be fine. I guess I need to do some shooting.
