A bit OT, but after a 2 year wait, Alliant 410 is now available.
I do not want to advertise a distributor, but if anyone wants to know where I got my 8 lb stash, please PM me. Waited a long time.

As an addendum, if anyone would like to post their favorite personal/commercial spec's for the 2.5 and 3 inch loads, please feel free.

I was a long time Hercules/Alliant customer.

Not so much now.

News flash: 2400 still works in 410 shells. They sold it for years as the 'shooters choice for 410', right up until they came out with '410'. I get better case life with 2400.

I used a lot of Promo. It shows up sporadically at the big wholesalers now and then, but Graf's and Gamaliel have not had any for years.

Screw Alliant and their manufacturers induced shortages.

Titewad is almost as cheap overall, and it's density lends itself to better crimps in the stupid AA HS shells. I also discovered International for light 20 gauge. Perfect powder for it.

I'm all for competition, and I'd like to buy US made products, but my loyalty to Alliant is long gone.

I can understand your/my frustration. Been there,
done that. All I want to do is say that Alliant 410 is out there to be had.
Best.

Understand, thanks.

It's good that Alliant is making powder for us again.

300-MP is Alliant's answer to H-110/Win296. Those powders give better hull life than Alliant .410 and 2400, or Hodgdon Lil-gun.

Downside is use of higher charge weights and dust sized powder granules migrating everywhere through your press.

HS .410 hulls give better hull life than old CF AAs. First time loading them didn't lose one case until I'd passed 12 firings. Internal capacity is also greater, so it's much easier to get the max NSSA shot charge to crimp.

Having a several lifetimes supply of the old hulls, so use: 14.6 gr 296, .410 AA/Yellow Duster/Orange PC, Win 209, #9s. 1240 fps. Sometimes substitute Fio 616 which ends up at 1200 fps.

My shot bar is reamed to drop an actual half ounce of 6% Sb shot.

Before the comments start, I shoot these in a well known brand of German manufacture that has barrels defaced with 'factory ammunition only', so I well know how lucky I am to be alive.

If you want your shot to stop jamming/bridgeing use import shot!
I get "0" shot jams with Argentine or Peru shot. Also my 9000G quits leaking power with Alliant 410. I load at least 2000 410's a year. The only thing worse than the leading american shot is reclaim in small gauges.

If it works for you, fine.

I'll take actual 'hard' shot in 410 please.

Bridging is only a minor issue, and with the PC baffle powder leakage is also minor enough that it's not a problem.

The 410 is a bugger to load whatever. That's one excuse why they cost so much. Even commercial loading equipment apparently does not run as well as with larger cases.

It's the one gauge I'm not about to try a progressive loader with.

I've loaded tens of thousands of .410 on Mecs progressives and Spolar. .410 work fine when you get your machine tuned up properly but you have to pay attention to details all the time. I use to love getting 800 loads per bag of shot.

I have two bags of the "expensive" Precision Reloading nickel plated shot on hand now to try in some .410 loads. This is advertised and touted as being true plating, not just a nickel wash. Between sending the Dickinson to Orlen for forcing cone lengthening and using the plated shot I hope to have some real dove killers ready by Sept. 2. My grease plate will tell the tale.

Gonna polish those new cones, Stan?

From all reports, that's the key.
