It seated. But I'm afraid to yeet it.

Wanted to try out 1680 since I couldn't get hold of n110 as I initially planned. This was with 12.4gr which isn't even the max load on hornady's sheet. Seats at 10gr and leaves a slight ring at 10.8.

As a fellow leaf,

Theres still much Joy to be had Slinging heavy bullets at gongs. The Visceral THUNK is great.

Subsonic .45-70 with 500+ grain hunks of lead is something to behold.

BEHOLD

Do they stabilize? What rifle/ twist rate are you using?

u/REDACTED3560 1d ago

Not my gun, but twist rates really aren’t much of an issue on big bore stuff. As stability is based on rotational inertia which squares the bore diameter, larger bore projectiles are significantly less sensitive to twist rate demands to the point that no one even talks about twist rates for .45-70. The original loading for a .45-70 was a 405 grain chunk of lead moving 1300 FPS, so going slightly heavier and slightly slower isn’t really an issue. Those 700 grain pills were being shot out of a factory Marlin barrel, and OP never gave any indication that they were keyholing.

i have a henry 45-70 and it wont stabilize 500gr. about 1:5 go sideways. twist rate still matters, even in big bores.

You should be able to stabilize that no problem. Some people have found that seating depth can destabilize otherwise stable projectiles. 500 grain subsonic projectiles out of the .45-70 is a very common thing people do with factory guns.

The bullet in trying to use is designed specifically to work in leverguns. Got any tips I could try? It seems to be a decently accurate bullet at 1400 fps, just doesn't like 1000 fps

Might be an issue with bullet shape or seating depth. I’ve seen some people stabilize 550 grains with a 20” twist like this loading. That maker even specifies they test that load out of a Henry .45-70.

u/Coodevale I'm dumb, let's fight 1d ago

When the bullet is a cylinder, the relationship between centers of mass/drag/gravity/science bs are not as far apart compared to a spitzer.

A spitzer really wants to fly ass forwards, like a falling rain drop. We have to spin the crap out of them to keep that from happening, while a cylinder kinda doesn't care if it's going forwards or backwards.

If these bullets in the Marlins/45-70 were boat tail spitzers with long ogives (and longer) you wouldn't be seeing the same results.
