I got some cast Keith style bullets off gunbroker and the auction said 255 grain,out of curiosity I weighed a couple when the came in.They came out to 268 grains each! I don't imagine there's 8 grains of lube on them so what is a allowable over/under on bullet weight for cast bullets and should I be concerned about loading them with that deveation of weight? What powder and charge should I look at? Or should I contact sell and see what he will do?

I am guessing from the bullet weights that this is a 45 Colt? New Vaqueero or Vaqueero?

My bad Rabon your right it's a 45! It's the older Vaquero.I was just looking on reloadammo.com and there's nothing for 265 grain so thats why I'm asking this bunch...lots of good experience in here! I emailed the seller with the same question so waiting to see what he says.8 grains isn't much but modding the bullet base to get them right doesn't sound like a safe option.

Probably speced out for a different alloy. The harder alloys are lighter.

In a small bore, the difference would be negligible, but not a bullet this big.


I cast round lead balls for my ¼-scale 12-pounder Napoleon. The ball diameter is 1.125"

The difference in weight between a pure lead ball and wheelweight ball is 72 grains.

Not unusual at all. My "250" grain Keith bullets wind up a little over 260 grains when cast out of wheel weights. I just use 250 grain lead loading data and look for pressure signs.

+1 I never start out at max anyway.

You will probably have to try diff bullet weights to find what works with your sights. I use a 335 cast with 24 Grs W 296 in the New Model SA Rugers chambered for the 45 Colt you won't even get close to a maximum load in your Vaqueero.

I can't think of a need to shoot max loads in the Ruger,I always shoot mid range loads.I may get close to high end with jacketed loads but for cast I go with moderation! I'm just going to start with 255 loads and keep my eye on them! Thanks guys...I got my new grips in and should start checkering on them soon(Dads doing the work actually)!
