Winchester 452AA

[mwx40x40]

Probably been asked before but could not find what I was looking for. First question, can data for WST be used for 452A? I would like to use it 40sw w/ 180 Bayou's. Any proven 452A loads for this combo?

Load data for ww452AA is hard to come by these days and I don't have any info for it in a .40. Used to use a lot of it at 5.7gr in a .45 with 180gr SWC and it made about 180 pf. You could look at the following data from the Speer manual and compare it to WST and 231 and probably figure out a good start point and work up a load for .40.

I still have about 3 pounds of it and have been using it for steel challenge loads in a .38 super. It is a good powder, and in case you didn't know be aware that it is inversely temperature sensitive.

Thank you Bamboo

still have about 12 lbs of 452AA. luv the stuff for lite loads in 38 supercomp. the chrono data i have from many years show WST pretty close. in 38 super, WST is a tad slower with the exact same amount of powder. this using 115-125 gr bullets. have some load data for 45acp, but none in 40.

Nothing in .40 but my old match load was 5.2 grains of WSt and 200 swc in .45. Great powder!

I found some at a gun show but only loaded 200g lead in 45 ACP. I found a great target load.

Then Pat's had solo 1000 and Scott 453 so I got a bunch. I load the scot 453 with cast 180g in .40 to 1.135 OAL. It started getting snappy and changed gears at 4.5 grains and it was still not major for me in my 4.5 inch SIG barrel(a lot like WST). Your powder is different so be careful. You might be able to get to major more safely if you can load longer OAL.

From a Winchester loading booklet

The new Winchester Super Target (supersedes 452AA)

The new Winchester Super Field (supersedes 473AA)

At the time Winchester Super Lite was brand new.

There were only loads for the new powders but as I recall we used 452AA for steel loads and 473AA could make major with heavier bullets (38 Super)
