.410 shotgun reloading specs

[ziggy-73]

hey i had a house fire and lost everything so im getting a new .410 reloader and i dont have any of the old specs on what i used to use since my press was set up already and i didnt have to mess with it. if anyone has some quick set up points for a mec reloader running 2 1/2" remington hulls with winchester 209 primers and winchester 296 power and than plan on using #8 shot. let me know what ya guys might run. thanks

I use a MEC 9000G .410 progressive press. I load Win 2.5" AAHS cases. Win 209 primers (now Cheddite as Win are not available), 15.0 gr of Win 296 (H110 is the same powder), and a CB5050HS wad (the Win wad clone that is required for the AAHS cases. Check on the Hodgdon reloading website and you'll find this load and a lot of others.

I have read that Remington .410 cases sometimes are difficult to seat a Winchester primer to full depth. I have not tried Remington .410 cases so am only relaying what I've read.

I do advance the 9000G manually like a MEC Grabber (I disconnected the gas piston) as I find that I need to tap the shot drop tube with a screw driver handle to ensure the shot always drops...maybe one time out of 25 it doesn't drop and makes a mess when I run the 9000G in auto advance mode.

Good luck with it. .410s are fun to shoot and well worth the extra effort to reload for....$5 a box for reloaded ammo vs $20 for factory ammo here in Canada.

i just ordered the 9000g. do you know what size bushing you use to get the 15 grains of powder?

and yeah i have reloaded about 500 of the remington hulls and yes the winchester primers are not perfectly flush but it seems after being fired once than they open up and are flush the second load.

I use a #12 bushing. It drops between 14.8 gr and 15.0 gr of Win 296 the way I operate the press. The bushing should come with the press, or at least mine did. I did add a 12A bushing to inventory last year but haven't see any reason to use it at this time (contemplating a semi-auto .410 though, might come in handy for it). Of course, weigh your drops as you will pull the handle different than me, and your bushing is likely slightly different than mine, and you'll have a different lot of powder than I do.

My biggest piece of advice with a MEC 9000 or Grabber is to pause briefly at the bottom of the down stroke, and make sure the charge bar is tapping (hitting )the screw head on the bar mechanism frame as it goes to the left on the down stroke. That seems to get a complete powder drop every time. If you cycle too fast you get light drops, and if the screw head doesn't tap the frame, the same thing occurs. This issue is worse with the smaller bushings in the .410 than say a #30 in the 12 ga, but the same advice applies there.
