Can you list the exact load data you found in Lyman's?

You might just use two nitro cards or the cheapest without resorting to food products would be 1/2 of a 1/2" fiber wad overshot. BUT, before you do that check the weight on your shot charge. You might just need to add a few pellets IF your shot drops by volume are light on weight.

 

Putting the felt atop The shot is 1000x better than putting it under the WAD.

The correct fix is a taller was.

Is this a basewad issue?

Oh.

Your hulls are too long. New Fiocchi hulls need to be trimmed to length. You might buy a hull trimmer or you can make one.

 

If that is the answer... do I just cut off say 1/4 inch (lenth of the felt wad)? or is there a specific length of the 16 ga shell that it should be before crimping....
The new Fiocci shells are exactly 2 3/4 " long.... isn't that what they should be (total length)

Next question.... should I take apart the 25 loaded shells that I have now,,, then trim them and reload... or could I shoot them as is.......with the felt wad

 

Yeah, they should be 2-3/4" open so you are okay there.

Are you using any wad pressure? Try using less, even if you are not using any at all. Sometimes that works. Also double check your powder and shot weights on your scale. If you are measuring by volume you are probably light.

 

put the felt in the shot cup under the pellets.
if your uneasy doing that shoot, some patterns both ways and see what you get.

 

Although it's a listed load those Remington wads are less the ideal for Euro hulls. For one thing they are 1 1/8 oz wads and they tend to get powder migration in the thin wall hulls. Get some SG16 wads from BPI. If you want to use up the Remington wads use a filler in the wad. Lots of guys use Cheerios or beans. I use Air Soft BB's in the bottom of the wad. Good luck.

 

Put the wadding UNDER the shot. (In fact, I would put it in the plastic wads in advance of starting reloading so as to keep the reloading sequence normal and faster.)

Otherwise, the big chunk of non-aerodynamic felt wadding may interfere with the patterns after it leaves the muzzle.

 

I might put the wadding(if needed) overshot, because putting it under shot might raise the shot column above the wad petals, which would increase pellet scrubbing, which also affects patterns. IMO, only way to really know for sure if over shot or undershot patterns more evenly is to load up a couple of each and pattern them.

Edited to add, I just took a caliper to what was a new Fiocchi 28ga hull that was trimmed to fit a Fiocchi hulled steel shot load. I had trimmed the hulls to fit the load and it measures 2-11/16" . Hmmm, no wonder I didn't need any press adjustment from my WinAAHS hulled lead target loads. The win 28ga. AAHS usually measure 2-11/16" to 2-5/8".

So, wadding or trim and adjust press crimp, either one will work.

 

My go to TSS turkey load uses a felt over the load . Patterns are awesome!

 

Felt under the shot will reduce pressure and may reduce speed. It allows the shot to set back in the wad cup after firing delaying pressure build up.

I have put felt on top for some loads. I would just load a few that way and check patterns before doing a bunch.

 

Felt under shot may reduce pressure...

Are you sure? Reduce pressure compared to over shot? Impossible!...?

I'm not convinced that overshot cards affect patterns in any discernible way. Even the patterns from those 28ga. steel shot loads I loaded were as even as can be, and that's less dense shot which would be affected by cardboard more than denser lead shot. The only way to find out for sure is to compare patters from both with and without o.c..

 

Any spacer material goes under the shot, not on top, where it can interfere with the pattern. Even my old Sears [ reproduction ] catalog in their reloading section says to use a thin - .028 - overshot card. Using a thicker one will put holes in the pattern. I tried a .060 card hoping to not have to glue the OS card in all brass shells. I shot perfect donuts and ruined my scores for a SxS shoot. And you wouldn't want it first before the plastic wad, it could interfere with the plastic wad sealing properly. You know, a navy bean, popcorn kernel, anything to take up a bit of space dropped in the wad would also work. Good luck, hope it all works out. Let us know what you decide upon.

Felt under shot is compressible this allows the gasses to expand more before moving the shot. From looking at test data from tss loads it does lower pressure. Not by much, but it can be measured.

 

I had not heard of that. That's interesting Slotracer 577.

 

Went to the range today and shot off my box of 16 ga 1oz with the 1/4 felt wad over the shot. All loads worked fine... and the felt was not even seen as I fired... seemed to desinigrate completely I would assume. (note, I can see overshot cards when I use them,, but was surprised that I didn't see any white felt wads)
That said,,, I feel that the 1/4 felt wads over the shot is the trick here to get the hull to crimp correctly,,, not having to do the alternative of cutting down the hull... thanks for all the advice... joeg

 

If it works, go for it.
