I read that for doves you should use an improved cylinder because u get a better pattern for the doves than u would with a modified, what do you all think? And what load will you be using for doves this year?

I use skeet in my top barrel and improved in the bottom. I'll be shooting an 1 1/8 ounce of 7 1/2 and 8's. It's what works for me, but there are guys who shoot skeet, full and everything in between with excellent sucess. To each his own.

I usually shoot a mod. with #7 1/2 usually just a high brass 2 3/4 shell

I shoot a Briley extended LightMod

i used a modified with 7 1/2 high brass when i hunted them. worked well

Modified Choke ( I usually let them get out a ways first)
#7 Low Brass
#6 High Brass * for long shots*

I use improved cylinder with #8 shot. Does the trick for me
