What kinnda loads with AA1680 work in your 357max guns?

Grabbed 2 lbs of it a month or so back for $15 each....wow. 😬

Revolver or Contender?

38 grains under a 525 grain WLN. Sorry, wrong Maximum!

Kyode in a Contender my testing last fall included 1680.

13" MGM Barrel
1680 Powder
180 XTP Bullets
Jamerson 357 Max Brass
Remington 7-1/2 BR Small Rifle Primers.

25.5 grains with the bullet seated long.
1725 fps SD 56

25.5 grains No Note on Seating Depth probably lower crimp groove
1829 fps SD 61

26.0 grains with the bullet seated long.
1763 fps SD 97

26.0 grains No Note on Seating Depth probably lower crimp groove.
1862 fps SD 40

26.5 grains with the bullets seated long.
1901 fps SD 73

I am not sure why I seated some of the bullets long a year later. Probably Case Fill. If I remember correctly 1680 with top end loads is a case full.

Normal Cautions start with Book "Contender" Data and work up slowly.

Contender.....but all conversation welcome. Like to have a max ruger sometime. Never seen one local.....yet.

Lol whitworth 😂

Thanks bob! More users....jump right in.

I picked up a brick of cci 450 mag small rifle primers. I think i may have loaded cci br primers previously....i forget. They are too pricey for that now lol.

What bullet? How long are you planning on seating them? The alliant manual shows a couple contender specific loads...

28.3 max 180 xtp coal 2.025 1,884fps 39,0000 psi,

180 sspb 30 gr max 2.350 coal 1850 fps 27,500 psi,

200 FTX 30 gr max 2.5 coal 1887 fps 35,800psi

12.5 inch barrel these are alliant arms manualloads specifically for the contender I can post a screenshot if you'd like.... And now im not only soaked through im getting iced on.... Lovely ohio weather her at day to hunt.... In going home lmao

Yeah....ive got that data but thanks. Just curious how many use it, how well they like it, n what bulets/charges worked.

Ill try the 180gr xtp in the lower cannelure first. Who knows when that will be but im always thinkin. 😉

I would push all 3 bullets harder than that myself...

The contender frame will take 55,000 psi with that case head diameter according to mike bellm
