Magnum shotgun powder

[sissyhunter]

I am the newest member so hello to all you shotgunners. I have six shotguns ranging from 20 to 10 gauge. I'm going goose hunting in Washington in December and I want to reload magnum 10 gauge shotgun shells using Hevi shot (bought 7 years ago when it was more reasonable). I also shoot muzzleloaders using smokeless powder (legal here in Hawaii) like N110. I have many bottles of N110, and I saw a blog by a guy in Finland who had used it (64 grains) in a shotgun load. Has anyone seen any book etc. that shows the use of N110? I'm OK with buying new loading material/book since I haven't been loading for awhile, but not if they just use Blue Dot. I have the Lyman Shotshell Reloading Handbook from 2000. I also have Lil Gun, H4227, HS-6, IMR SC4759 if any of those can be used. Thanks

Go to Ballistic Products and look at their manual for reloading the 10 gauge. http://www.ballisticproducts.com/
These guys have some good stuff.

Let me ask the members this. I don't know the reloading "lingo", so maybe you folks can interpret what this "recipe" is saying. For example, I don't known what 12/76 means, although I'm assuming 12 means 12 gauge. I won't use this recipe without further corroboration, but it will be a start. What amount of powder (metric measurement or otherwise) does this recipe call for when it says "64,8gr - 67,9gr"?

Recipe for 12/76 lead
hull: Winchester 12/76 supreme
prime: Federal 209 A
powder: Vihtavuori N110 64,8gr - 67,9gr
wad: vp-65 (vagnerplast wad from denmark)
pellet: nickelplated lead 3,0-4,0 mm, 1 3/5oz (46 g)
velocity:1509fps - 1660fps
pressure: Max 1050 bar (67,9gr powder and 1660fps load) cip standard

12/76= 12 gauge, 76mm long.

64.8 gr= 64,8 grains.

Be advised that's a fairly hot load.

Thanks for the info. It seems N110 and 2400 are used in equal amounts in small rifle (22 hornet) applications, but I can't imagine usint 64 grains of 2400 in any shotgun shell. It is confusing, and I wonder if it was a mistake.

[Virginian]

Do you seen any similar loads with similar weight of 2400 powder. That do seem like a LOT of 2400 to me too.

Never having heard of your brand of powder, I do have what I think is the latest Lyman book (5th edition) and it does include some info on VihtaVuori powder from Finland, but only for N310, N330, and N340. It says nothing about N110.

As for the rest, it seems that you got some answers. http://www.duckhuntingchat.com/forum/viewtopic.php?f=14&t=207005&start=0

One thing that is unclear, at least one thing, is that the 1050 bar may not indicate the maximum pressure generated but that the shell would be safe for guns proofed for such pressue, which I believe is roughly equal to 15,300 psi. I also note that you are using heavy shot and not lead. I believe that since hv is denser you may find that the same weight fails to feel your wad's shot cup. If so I don't know what to recommend. My suggestion is although you have bottles of N110, if you are at all unsure about a recipe to go with a powder for which you have a published recipe.

[sissyhunter]

Thanks everyone. I've probably ridden this mule as far as she'll go. I've asked on two other forums too. This is great that you can find answers (for most things) from good people willing to help others. Maybe I can find a book on the characteristics and ballistics of fast/slow powders in shotgun shell use.

[sissyhunter]

As it turns out, I did some testing on my own and N110 seems to create moderate speed with 50 grains, but at 55 grains it seems to not totally ignite. I can't imagine usind 67 grains as in the Finnish recipe.

I don't see any recipes for 2400 in any shotgun other than .410.
