.470 light loads

[Gareth flanged]

Hi

I'd like to use my .470 in the indoor range. I'd need a light loads with a soft lead bullet about 700 ftlbs.
Does anyone have experience of such a thing?
I'm wary of the case powder capacity.

My experience is you would be exceeding any indoor range caliber constraints with a 470. Second you must be a reloader to do what you are attempting. If so your filler would take care of any capacity issues

Take a look at the Lyman Cast Bullet Hanbook. It will give you an idea of what’s possible with other cartridges.

I would think that you could approach this from the other end (history wise anyway) and look at what smokeless loads the 500/450 magnum shooters are using.
H4198 with a backer rod filler is where I would start.

You’d be surprised, I used to take my .470 regularly to an indoor rifle range and was approved by management.

They always told me no…anything with a 3 yes 4 no.

I've run into the same mindset.
338 Win Mag is OK but a 45-70 is not.
Makes zero sense.

Depends on the type of stop system they have, some have velocity restrictions others bore diameter.

And yes I was using full power .470 softpoints.

don’t misunderstand me…I think it’s awesome you can shoot a 470 in an indoor range…I just can’t…have to go to my farm

Must be a rarity to find an indoor range with that level of capability .

As others have mentioned, I would go with 4198 and a foam filler. You likely won’t be able to get down to 700 ft-lbs without nearly filling the case with foam, and I’d be worried about bullets getting stuck in the barrel at that speed. Stick to around 1500 to 1700 fps and lead bullets or jacketed pistol bullets.

Your range limits you to 700 ft-lb muzzle energy cartridges?

Your bigger issue will be regulation. It is unlikely a load that light will regulate properly.
