Help me find my next choke

[RiverRoost]

Currently shooting a rhino .670 and nitro H518 4/5/7 blend out of a sx3. I have too many H518 to justify going to another shell and would like suggestions on which choke to move to next. Been shooting this rhino for several years and am getting around 255 in 10" @40 yards. It's not the 280+ that Nitro is advertising with that choke so I'm hoping a choke change could get me a little higher numbers.

How many pellets in a 10" circle do you want? Is that 255 in a well distributed pattern?

How dead is dead.  LOL

Now I would try a different choke.   You have a few to pick from.   Now we run the 665 to 675 in that gun

I know I know! I'm not real sure why I want to tighten it up but I guess part of me buys into the numbers craze and part of me has a thought that it could just be a little better. I'll try to post up a pic

Here's a pic of my last pattern. I'll try to clean the barrel real good this year again and test some more and more chokes. I've also got a rhino gen 1 .660 to try
