Starting to form up on .414 Supermag 225gr lead load

[Elric]

After I finish diddling with 210gr plated bullets in a .41 Mag, I have about 50 SAECO #415 220gr GCTC bullets, sized to .412, and lots of Unique.

I also got a gas check flare tool from NOE for my .41, it seems the SAECO gas check shank is a wee bit large for Lyman 410P1 GCs from Gatorcheck. Putting the unflared GCs on the #415s was a lot of diddling, starting one side, or sorting through individual GCs for a less tight fit....

There's another box of 50 #415s that I need to size and put on GCs, so I expect I'll get to use that NOE tool.

The options I discarded - anneal the gas checks or use a ball bearing to flare the gas check, were even more diddling added to a diddle-fest...

Man, those things sure look familiar......

There is just too much variability in the .41 mould GC shanks. Before this, I was slapping on 35 caliber and 7mm GCs without a thought, but for some odd reason the 41 is a game all it's own...

The check fit problem isn't the Gator checks, it's the SAECO mold. About 30-35 years ago I gave up trying to get Hornady checks on several SAECO molds and started experimenting with various methods of sizing the checks to fit properly. I've several SAECO molds and they are all pretty much the same, checks don't fit the SAECO shank regardless of alloy.

I have problems fitting gators to my Lyman 610 mold too.
I have to use a little tool I ground from an old screwdriver to pop each one open.
airc at one time they made a 41 and a 41 'thin' check.

Gator has two gas checks, the Lyman P1 and the other (BSS?). Plus there is the .416 GCs.

I have a 410610 mold as well...

EDIT: Woo-hoo! Found the 50 cases I got out for deer season, aboud 8 that I fired during zero, 12 loaded with 210gr XTPs, and the rest primed and ready. I think I will pull down those XTPs, not what I want to touch off... But these hulls will be sweet for those SAECO #415s....

To my great suprise, a tech from Swift Bullets called in response to my question about .414 Supermag. No load data. He did say the AF/HP 180 grainer will develop pressure a little earlier due to the jacket material.

Still, he said that folks have used this A Frame at velocities up to 2500 without any failure. Which I never even questioned...

I just sent a note to Accurate Powders, I have their reloading guide #1 or so, it has the .375 Supermag... No 414 Supermag

they should have data for the 445, so I can't imagine 414 being left out of the mix even if it is just a cursory load or two with AA-1680 or xmp-5744

Well, the tech thought it was released @ 2000, and I sent him a link to "The Silhouette" article from Mar-Apr 1994. Who's the alpha geek now?

But even at the beginning, AA1680 and (XMP) AA5744 have stoked the fires of the .414 Supermag. But he did turn me on to AA4100. I've seen suggestions this is a continuance of Scott 4100. Dunno.

Two loads for 5744, 170 gr and 210-220 gr
Three loads for 4100, 170 gr, 210 gr, and 250 gr
Three loads for 1680, 170 gr, 210 gr, and 250 gr

4100 is the half step twin to 2400.
I started using it quite some time back when I got about 15 lbs of it in a swap I made.
since then I have been mostly using it in the 300 BO with 110gr jacketed bullets, but have also given it a run up in a few rifles under cast bullets.
I have even used 2400 data directly for it but stayed 1/2gr lower to start.

Went up to Farm and Fleet, picked up a three pack of 3cc syringes with 22 ga needles. Eventually, I'll stagger upstairs, get my .414 SM, crawl back to the basement, load up a SAECO #415 as a dummy to just shy of the lands, and get the OAL, seat depth, and remaining case capacity. I'll send the measurements to Accurate and ask to calculate 1680, 4100, and 5744 loads for it.
