Bushing number for Mec using 40 gr 3F APP

[Double Tap Taylor]

Looking to save time and coin on Mec bushing to be used with 3F APP powder, this is by volume need on for 40 gr. 

Or what bushing are you using for what gr by volume.

I had a universal charge bar finally break. 

Thanks in advance

40 gr? loading .410s?

Beartrap no medical issue, i do load 410 with black, using 3 inch hulls, all powder and not even a 1/2 oz of shot, nice out of derringer at night skeet

Thanks Pard that will work.

Save a little more $$ and use 2F APP in your 12 ga shells. I use a 37 bushing (about 39 grains of 2F APP)with 1 oz of reclaimed shot and the reloads work just fine. 

I had to correct myself. I had been using a 42 bushing when loading 1F BP

For years I used a #41 bushing, then a few months ago someone commented on how stout my loads were and asked what my charge was.  I didn't know, so when I got home I measured it.  It measured right at 60 grains!  I ordered 4 bushings in the mid 30s.  IIRC, I'm using a #37, dropping ~40 grains.  With aBuster CB01138 wad, Winchester AA hulls & 1 oz of #9 shot I get a nice crimp and no dribbling of shot.

FYI…..

if you look on eBay you can get 3D printed bushings that work just fine, and cost a lot less than the aluminum bushings.

Load by volume to get to the proper stack height. Forget about grains. It’s irrelevant with BP and subs.

The MEC bushing is a volume measurement against my BP volume measure.  40 is the reference number at the  mark nearest the volume filling a #37.  So, for all intents and purposes, 40 whatever is the way to communicate that to another individual.  Just like 50 is the reference number for my Hawken target load, & 100 for my hunting load.  All of which comes very close to the weight in grains for that amount of 2F Goex on my balance beam scale.   So, for simplicity's sake I call it grains.

To each his own on references. If it works for you, all is good.  

 

With my Mec, a #31 bushing throws 40 grains of 2f Goex BP compared to your #37. The thing is, that same #31 bushing will throw different weights depending on the brand of BP, granulation and BP subs. My point for the OP and others who ask this same question periodically is to find the bushing that throws the volume needed for the correct stack height for the weight of shot and wad. If I say use a #31 bushing, I've no idea what the weight is for APP. But I'd use that bushing for APP because it throws the correct volume. 

 

Captain Baylor did a wonderful chart eons ago that showed equivalent weights & volume for BP and subs. It's no longer available online that I can see, but I believe it's covered in his new book. Perhaps others can chime in on that.

Not sure if this is the chart you are looking for or not.
