.357sig vs. .40s&w for a reloader?

[IM_Lugger]

I reload for 9mm and so it makes sense to get .357sig that way I use the same bullets to load both calibres. The down side is factory ammo/ brass availability and cost.

If I get a .40 I can use the dies and the bullets to load for 10mm when/ if I get one (always wanted one). But .40 bullets are more expensive than 9mm/.357sig. On the plus side .40 factory cost’s less than .357sig

.40 all the way, the brass is almost free, the bullets cheap, and using the same projectiles doesn't actually make life much easier; both are cheap. In the end, a .40 will cost less.

I was thinking .357 would be cheaper; since I would be reusung brass and 9mm bullets are even cheaper than .40...

Differences are minimal... just don't use .40 brass to make .357 brass, your necks'll be too short and watch what 9mm bullets you use. Space (and tension) issues for 'sloped' rounds.

Not sure exactly what firearm you are looking for, but many 357sig and 40 platforms allow for a bbl swap without even changing springs. Same mags too. Buy a 40 and pick up a 357 bbl. Then you can convince the wife that you'll have to spend a lot of time doin a lot of 'testing' (in order to save $$ of course)

Good advice from canuckgunny. As for price, .40 is cheaper, both in factory ammo terms and in brass, .357 brass isn't cheap or plentiful, .40 brass you can't turn down enough of. As for bullets, the price difference between 9 and .40 is laughable.

How much cheaper when you go to a lost brass match?

40 is cheaper in the long run then.

Good plan to get the 2 barrels for the same gun, then you can change as needed, Lee makes dies for the 357Sig, there are some people selling brass here, 357Sig is pricey but a fun and accurate round. I have seen people leave their brass behind because they don’t reload, I have about 50 casings which I will keep for when I get my .40cal Sig.
