12 GA 3 inch Duplex loads

[Fishh2o]

I've been shooting a 2 3/4 1-1/8 oz load with 1/4 tss. I want to up my payload and looking for loads to try. I want to use with either of these hulls:

Remington Plastic with Plastic Basewad - 12 Gauge 3" & Remington SP Plastic with Plastic Basewad - 12 Gauge 3"
OR
Federal One Piece Plastic - 12 Gauge 3"

I'm looking at #3x9tss for puddlers or #2X9tss for the salt water since its longer shots. Do you guys have any thoughts on loads?

I've got 3" Federal unibody data for a 1-1/4 oz (3/8 oz TSS x 7/8 oz steel) going about 1330 fps. PM me if you want it.

Don't forget to experiment on the order of stacking the two types of shot. TSS on bottom will blow through the steel, disrupting the pattern significantly - which can give you a great load. TSS on top gives you a tighter pattern, as a rule of thumb. Sandwiching steel above and below TSS gives a different option also.

Hal,

What are your thoughts on the % of TSS to use? I've read somewhere that 20% of the load is what you should shoot for. If I have a regular steel recipe and substituted 30% with TSS in your opinion whats that do to FPS and pressure?

It depends on what outcome you're looking for.

For waterfowl loads, 20 to 25% by weight seems to work very well to "spike" the shell's performance while keeping costs down. 1/4 oz with 7/8 of steel works very well. If you go to a higher ratio than that, you have to be more careful about how you stack it.

If the goal is to do something radical with the shell, such as a heavy spreader load for turkeys while retaining long range capabilities, something like 45% TSS under lead works very well.

What affect does different crimps have on the duplex loads? i.e 6 or 8 or a roll crimp? Forgive me if question is not worded right. Im new to reloading.

As far a fold crimping not too much.. If you roll crimp and compare to fold crimp the rolls have less pressure and lower FPS.

What length of brass is recommended for the tss shot, 12 gauge 3" shell for turkey?

[Fishh2o]

brass doesn't matter at all.
