Hard Cast and Bottle Necks

[luckyM13]

I was looking at Rimrock's .32 cal selection and as awesome as they are they provide thorough dimensions... Im loading for my Colt Police Positive Special and .32 WCF's case neck's only 3/8" and a few bullets I'd be curious to try, including the full profile WC's length to the crimp grove exceed that.
I recall reading many decades ago in a Lyman manual to not seat below the neck and so I've always avoided with not only cast but jacketed also. I can see an issue with cowboyish cast but would it really be an issue with hard cast BHN 15-22?
I really like that little exact same full profile WC in Buffalo Bore's .32 S&WL, would like to give it a shot at around 1,000fps from my PPS

You'll have no issues seating those cast bullets below the neck. 1000fps is childs play with a cast bullet.

Load them up and enjoy

why do you use such hard bullets?

Penetration, lack of leading if I'm so inclined to hop them up.

If bullet fit isn't ideal, "hard cast" and "soft cast" will both lead bores. Hard cast will probably lead more. Penetration may be about the same. Lots of changeable factors involved here. It's worth reading up on.

.001" over grove diameter under 1,200fps, it'll be alright. I have no issues with a similar sized BHN18 RNFP @1,050

You'll only have about .087" of bullet extending below the neck. Like Forrest said, no problem. LIke any new load I'd drop back a little and work up the powder charge.

Yeah, always.
Yeah it won't be below by much.
Is the concern combustion around the skirt could deform and cause accuracy problems, or something?

The larger concern, IMO, is the ammunition stored where the lube could melt and contaminate the powder. If it's contained in the neck, that won't happen.

Fortunately the lube groove wouldn't be below
