Is a Spherical Powder (ball) that* may not down load well. The 0.6 oz. of #2 buck may not produce enough pressure . A squib will be the results. Imo.
That guy is a blast to watch , he's the one that got me started messing with shotgun.... MannyCA also does some neat stuff and is a nice guy...
For the life of me I can't lay my hands on my Lyman manual. I would point to the fact that in all the data I can recall buckshot is listed as separate data from birdshot--as is tungsten, bismuth, and slugs. The mass may be the same, but the internal ballistics are different. No offense intended. I tend to be conservative and stick with published shotgun data.
These loadings run from about a low of 7,500 PSI to maximums of about 11,400PSI.
Here's some guide lines when loading buck shot. Use a three or four petal wad. They offer more protection for large shot. Deformed shot doesn't fly as straight, or as far as round shot, it also loses velocity quicker. So use a buffer like ballistic specialties #47 to protect the payload. The buffer together with the shot will have to be weighed together so you can find a powder load. Here's some shot pellet counts for #1, #2, #3, #4 buck. There 10 #1 pellets in one ounce, 14 #2 pellets, 18 #3, and 21 #4 pellets in one ounce. Combine the number of pellets and buffer and weigh on a scale. If it's an ounce and 1/4 combined, look for a 1 1/4 oz. load in your shot shell book. An ounce payload is an ounce payload. Velocity will be the same as well for an ounce of buck shot with buffer or an ounce of #8's without buffer.
This!!! BPI has a little specialty load data booklet that is worth every penny. It is full of loads for slugs and buckshot. There is more to loading shot shells than just getting a charge of powder and a weight of shot. You should have the correct wad and usually most buckshot loads, while they don't really require it, use a buffer. This is plastic little fine beads that help produce a better pattern. Pattern is everything when it comes to effective buckshot. Not just tight either, you may want it to open and disperse sooner in a defense type situation. Bottom line, don't follow the rules and best case you will spend money to accomplish nothing and maybe even wreck your gun. Worst case you risk injury.
Absolutely no offense , thanks for looking I had mine laying on the table beside me because I am fixing to change hull brands for my skeet loads to Remington... The new AA just are not what they used to be.... I kinda thumbed through it in the buckshot section... I tell you what untill I can find out a little more I am going to delete my comment.... Shotgun reloading can be dangerous and I don't want to throw any bad data out there....I also only use published data in shotgun , you can make a big mistake just using the wrong primer... Something I honestly can say I don't worry to much about in pistol or rifle..
Hmmm, I have a low opinion of Win LR when lighting heavy loads but never had problems with 209's in shotshells.....when they're constructed correctly for a complete fill with a tight crimp.
