I am anxious to see how it patterns with both the heavy-shot blend and with the Federal Mag-Shock #6's with flitecontrol wads. How about it Clark, any info for me up front on tests you have run?
I know this isn't actually a Fed. Blend question, but thanks for any input in advance of patterning.
The Flitecontrol wad that is used in the Federal lead loads is different from the Flitecontrol wad that they use in the Heavyweight shot loads and it's more forgiving. The "ideal" exit diameter is .670 and again idealy, it should have 1.3" of parallel section leading up to that e.d. a muzzle that is crowned and not slotted can also make a difference. (I have however seen some guns that prefer chokes as tight as .650 with the Flitecontrol wad shells. Internal geometry seems to be more inportant than jsut the e.d. as does the muzzle design.)
The #7 shot Heavyweight shell is also more forgiving than the #6 shot shell. I don't know which brand of choke you're using so I can't tell you anything about the internal geometry of it of course.
If I were getting ready to evaluate those shells through a new choke, as you are, I'd deep clean everything and then fire at least 5 rounds of the lead shells at big paper, without cleaning between shots. I'd clean the bore and choke very well with solvent, brush, patches, etc. and repeat the process with the Heavyweight shells, again without cleaning between shots.
The Flitecontrol wad can be tempremental and responds at times to a slightly fouled bore and often yields its best patterns on the 4th or 5th shots. At other times it likes a clean bore. By starting clean and then allowing the bore/choke to foul, you can find out which works best in your gun. If you clean between shots, you'll never know.
It can be a "challenging" shell to pattern. I'll be interested to hear your results.
