350 Legend and Cast Boolits

[Oldfeller]

I tend to agree that a simple powder coated plain base cast boolit running ~1,750 fps~ is a good range to be in.

Problem that I see is not getting much violent initial expansion out of such cast slugs, especially the ones with any "good feeding" nose form on them. Game will still see very moderate (and somewhat rather late) expansion and a lot of bore through holes after expansion stops.

Meplat splash wound channels will be most of what we can get out of the Legend when using cast boolits, unless we can provide for some rapid expansion.

A PC plain base is gonna be 100% fine for ANYTHING a 350Legend can push to, velocity wise

So you're saying I can run my 180gr Cast#2/ALOX at 2,100 fps/41,000psi as a plain base ?

Is that boolit powder coated?

We are discussing plain based powder coated bullets before, or I was, anyway. I have a mold with a gas check shank, but found I can simply powder coat the things and then stand them upright on the GC shank on the cookie sheet and the melted coating flows down the bullet sides to fill up most of the GC shank reduced diameter zone.

So far I see no need to spend the effort putting a check in place, then coating over it.

Folks who still use grease lubes still have all the issues with bullet hardness and lube, etc. etc. and they generally find a GC is a very necessary thing. Once you go over to the pretty colored plastic coated bullets, life gets a little simpler and a little more forgiving ......

Someone post the 100m+ results/targets of 357 caliber/plain-base bullets:
- 180@2100fps or 200@2,000fps
- Accelerated from a carbine-length barrel
- Any lube/coating
- Any alloy. . .

. . . and lets chat.

I don’t have anything to add because when I shoot I shoot at steel at and not paper.
However some of the posts above are claiming about 1750 or 1800 with no issues. Not 2k

Either way. Looking forward to the continued discussion.

... H110 and lilgun both need a max charge to make them burn right. They both also should never be downloaded....

21gr is not a download, it is the starting load for the 200gr LEE boolit. I am not seeing this "burn right" issue here, the spread is 27 fps average.

Um.....

[Dapaki]

Wait... is this thread going to be the big "Boo-Hoo, I cant do that so everybody else is lying"? Let me know and Ill post in another thread.

I was going to chrony some shots today but I had this to deal with instead.

Who does this to their carb bowl? I swear I'll never buy used again...

[mehavey]

Details please.
Inquiring minds want to know....
(and I'll try it myself)

[Dapaki]

mehavey, look at my post on page 19.

I shoot sub 2" groups at 100 yards with PB PC C358-200-RF LEE boolits with my 350L from BCA. Whats going on with your loads?

[mehavey]

I also shoot the 358-200 to good effect, but gas-checked/ALOX'd.
Is that a commercially available plain base variant, or did you ream the gc shank out?


(BTW: How fast were you pushing it?)

I'll chrony them tomorrow if the rain holds off but it's posted as 1900. Yes, I cut the shank out for the PB version but even then, I am not seeing the minute of barn issue with this round with PC and the GC base without the GC.

[mehavey]

OK, I'll try it bare -- still shanked but no GC.
(ALOX'd variant)








I'l be honest -- Just plain thin-film ALOX has held up to some remarkable (2,500/223) velocities.

See post 362 of this thread for my sub 2 moa 200 yard target of a plain base ASBB HF red 200 gr at just over 2000 fps.

The gun is a 16" 357AR.

The 180s seem happiest at around 1830 fps and I am ok with that. That 180 gr load shoots sub 2 MOA at 100 yards, but not at 200 yards. I was having ignition issues with H110 so I ended up with WC 680 (I have a decent stash) as my 357AR powder. With WC 680, the case is pretty full even for the 1830 fps load and I prefer to avoid greater than 98% load density.

[mehavey]

Threw some naked-based/ALOX'd Lee 200's into the oven this evening.
If it stops raining, `will shoot them tomorrow PM.

Film at Eleven.....





FWIW: QuickLoad led me to Norma 200 and I've never looked back.

So you're saying I can run my 180gr Cast#2/ALOX at 2,100 fps/41,000psi as a plain base ?

Am I missing something? I thought PC indicated powder coated not ALOX lube? Maybe I have been in the dark this entire time.

[mehavey]

No, the issue in that question was centered an ALOX coated bullet.
I've never had an unexpected failure up to/including mid 40's ksi -- as long as the base was protected with a gas check.

We're going to see if -- all other things being equal -- just exposing the base of that same ALOX-coated LEE 358-200 bullet results in failure. (and by extension, whether the powder-coating on just the base effectively is a gas check)







I gotta tell`ya... since I have to pick up the individual bullet anyway to push them through a Lee sizer die pre ALOX, slipping on a gas-check in the same motion doesn't cause me much heartburn.

[kenton]

The text you quoted in post #382 specifically says a PC bullet
