Patterning question

[Cove]

I patterned the Federal Premium Heavyweight High Velocity Turkey Load in 3 inch 1 5/8 oz 7 shot and it was super, so I have gotten my Spring and Fall 2012 turkeys with it. The 7's supposedly are similar to lead #5.

I got some #6 for the purpose of follow up shots at longer range. At 5 bucks a pop I would like to avoid patterning again, though not a bit deal. More the time involved. My question is: Can I expect the 6's to pattern well, and similar to the 7's since it is the same powder, wad etc?

They might be close but I would take a shot with it. Just a change in velocity or the bigger pellets through the choke might cause problems.

Stick with the 7s if that's what you've patterned. They actually hit more like #4 lead as they have a higher density than the hevi shot, higher velocity and smaller surface area. Should be good to at least 40 yards as long as your pattern holds together.
