Mate in the absence of pistol powder I am loading AR2205. Still developing the load trying to reduce the amount of unburned powder.
I think you will be hard pressed trying to find any powder fast enough to use for reloading it though unfortunately.

Are you north of 10gns of 2205 in your 310?
Most powders
I have ar 2205 what gn do u suggest 125 gn progectile
With 2205 you’ll find a sweet spot between 9gr and 10.5gr - I would consider 10.5 as max though.

Fun fact, I measured FMJ ammo for cadet (Collectable ammo - #83 by juststarting), with average at 1063.23fps.
avg: 1063.23fps.
min: 987fps
max: 1239fps
Yes mate creeping up past it slowly which seems to be fixing the unburned powder problem however I’m having a little trouble with accuracy. It is a brand spanking new barrel too so I’ll give it a little more time.

Are you weighing your cast bullets?? Only way to go, if your serious about accuracy. But you will hear the pop/bang/pop…if you dont weigh them.
Mate my two cavity mold seems to be throwing two different weight projectiles. I have been sorting them accordingly. Going to get into it this week and hopefully get a few more loaded.
Im yet to find a mold that drops identical bullets…i have an RCBS 180FP thats close …
I run a Lyman temp gauge too now, only cast within a certain temp range…
I don’t like casting and Black Widow (HRBC are the same molds) didn’t work well for me. Not that the bullets didn’t work well, it’s the combination of projectiles and Bertram brass. But, this is what we have, so I work with that.
I’ve recently ordered some 310 bullets from these guys (they do sample packs, before you commit to actual box (750).):
120gr, about .308 at the heel. Used 9gr of 2205. Works well with Bertram brass. I tested a few shots before handing the gun and my ammo stash over to someone else to shoot… I just wanted to confirm zero and test new load. All seemed to work very well. Chambers, shoots, 50mm gong at 50m - boring predictability, with support at 50m I put 3 in the same hole more or less (witness: @sungazer lol).
Also, after shooting/fireformed, you don’t really need to size them either, just seat by hand to the heel and lite crimp…
Obviously, this is what works for me… YMMV.

Nice looking Cast range…i just bought 1200 copper jackets, to revisit swaging .312 174 gn to feed my 303s …
Quick update on 310 Cadet bullets from Boyne Bullet Co. Excellent. This is my go to from now on.

How accurate?
Pretty accurate?
I forgot you dont really shoot for groups, do you? Lol
I do, but rarely lol
Pretty accurate = about (smaller than) palm of my hand sized targets at roughly 80m. Seems to work. I consider that a win.

How did I miss this thread ??? I’ve been feeding my Cadet with APS350, 3.6gn, SP primers with Boynes Cast .320 RN, 125 gn pills, have a stash of 350 and 450 and a nice supply of AS50N which I use for my 9mm … been pretty good groups when the sights aren’t blurry… I saw the writing on the wall before the great famine hit so stocked up…
