Is anyone regularly reloading the AA16 clones in straight walled hulls with success? I've read the threads where folks had trouble, especially when carrying them in their pockets for hunting. I'm looking for a 1 oz load in Federal and/or Cheddite hulls going about 1,200 fps. The SG-16 and Z-16 wads work, but they expose a lot of lead to the barrel. I've loaded 2 different recipes (Green Dot and 20/28 powder) in once fired Federal hulls using the 0078-16, SG-16 and Z-16 wads. Using a MEC 9000 I'm putting approximately 38 pounds of wad pressure on the 0078-16s and have a nice, tight crimp in hopes that this will prevent or greatly diminish powder leaking by the wad. I'm going to load several boxes and put them in my car full time and every month shoot 5 over a chronograph and see how they perform. Haven't chronographed any loads yet as it is a bit chilly out this week.

I've tried to load 1 oz in a fed with the cb100 using herco and sr4756. Had dished crimps but they shoot ok for clays. Haven't tried carrying them for hunting. Also tried 1 oz in the cb100 in a Herter's using universal and a polywad spreader. got several bloopers out hunting so gave up on that combo. Was thinking I'd have to switch to one of the SG's. Which did you use?

Jeff,

Those wads may expose a little lead to the bore but......there is no bore leading and the patterns do not suffer.

Thanks for the replies. I thought it would be nice to use a wad that didn't expose the shot to the bore. I'll be shooting these mostly in a ported gun and was a little concerned about lead scrubbing on those icky ports. I have been making empties by shooting Herter's ammo and have not had a problem so far, so its probably a non issue. I'll probably end up using the SG-16. They are excellent wads, other than the short shot cup. I can drive out to Ballistic Products and buy a case of 5,00 for $132.11 with tax. After shipping the Claybusters are about the same price. I wonder if i can talk Federal into selling me some of their 16 gauge wads? I live 11 miles from the factory, but I don't have much hope.

FWIW; I shoot thousands of SG16's a year in a few different guns and have -0- leading in the barrels.

Aren't all 16 gauge hulls straight walled?

OW - basically !! the thing is an RGL is straight wall , but much thicker - that's why the SP works in them . But , take an SP wad and use it in say a Winnie , and the thinner walls create a bigger space for blowby etc . The bigger the flake of powder and the tighter the crimp , the more the possibility diminishes ! The Herko , BD , Unique family better , any smaller flake or Ball type powder you really need to watch .

I use the CB0078 wad in Herters hulls with 1 oz of shot. I am currently using 20 grains of Universal, and the crimps look like factory shells, using my PW375 press. I shoot them at the range, so I don't carry them around all day in my pocket, like hunting, but they perform well.

The only solution I have found is to pre-flare the over powder cup of the wad. I roll the edge against the rim of a spent 10 ga. hull and do so pretty hard. The resulting flare is permanent and pretty much solves the leakage problem. I tried using a golf ball to roll the cups but the hull rim worked much better. It is time consuming to "fix" a whole bag of 500 but doing so during a good John Wayne movie helps ease the pain.
I will note that last year I had a batch I didn't flare as aggressively and Hogdon Longshot still leaked past a few. I had it happen again while hunting in North Dakota last month while using some of last year's 1 1/8 oz loads using the CB WAA16 wads that I had "modified" without as much emphasis on making the cup as big as possible. It takes a darn large diameter seal to contain the ultra fine powders like Longshot reliably for those of us who routinely set off to find the horizon and a few birds in between.
The Claybuster 16 wads (both) are my favorite, too bad the obturating cup isn't bigger.

I believe European one piece wad designs help compensate for the typically tighter European type choke designs originally meant for use with loads having solid wads and no shot cups. More exposed shot above the shot cups probably helps open patterns out of these tighter shooting barrels.

Since most of my guns have modern American choke designs in the barrels, I've always liked the American one piece wad designs which accommodate just about all of the shot column in the shot cup. Even these wads allow a bit of shot to sit above the cup to help facilitate good crimping characteristics. The exposed shot settles back into the cups when the loads are fired. When used with American style choke designes, I've found these wads help produce better, more predictable patterns and performance down range, especially w/ loads designed for longer ranges.

The original one ounce WW 16 gauge wad shot cup has the same capacity as the Remington SP16 wad shot cup. Either will accommodate about 1-1/8 ounces of shot, but full 1-1/8 ounce loads can be crowded in the Remington RGL or discontinued WW compression formed hulls. Not so in the larger capacity straight walled hulls.

The Claybuster 7/8 ounce wad should be about perfect for one ounce loads in any of the larger capacity straight wall hulls like Federals, Cheddites, etc. Since the overall wad lengths and bases are identical, pressures and velocities should be the same as those using the Claybuster one ounce wads.

Crimps should be easier to form w/o the dishing problem if we don't go too light on the powder drops to obtain very low pressures or use powders w/o sufficient bulk. That means it's best to avoid fast burning 12 ga target powders like Red Dot and others like it. Of course, you can always use filler wads in the shot cups as well if you simply must load extra low pressure loads or use Red Dot or other similar fast burning powders.

my use of the cb0078 is in a trimmed(to 2.5 in) RGL, with 7/8 oz shot for my older guns and wife likes it the few times she`s tried shooting pasture trap.

Plus 1 Mr. Campbell.

I agree also. Use the Rem hull. My hulls in 12.16 and20 gauge are mainly Rem hulls with Win wads.
