Hi Everyone,

A family member wants me to start reloading 300 win mag and 264 win mag for them. I don't own rifles in either of these calibers but have done enough reloading to feel relatively comfortable with the process. I'd probably borrow the rifles so I know for sure whatever I end up with for a load is safe. In particular the 264 win mag (which I'd never even heard of) is very difficult to find and expensive when you're able to find it.

It would be nice if I could use a powder I already had on hand like Varget or N140. Looking at the load data on the Hodgdon and VV sites I see that they've published Varget loads for the 300 win mag but not the 264 win mag. Are there any other places online I could look for more load data for the 264 win mag? If I do need to buy another powder is there something that's generally considered good for larger magnum calibers that would work in both?

Otherwise I'm thinking of picking up some some Lee dies, .30 / 6.5mm projectiles, and maybe magnum primers if they're required.

Anything else I'm missing?

Thanks,
 
Never heard of 264wm eh? 264 winmag came out shortly before 7 rem mag, and the 7 stole its thunder. Case is virtually identical other than bullet diameter, but the 7 had the option of much heavier bullets.


Nosler lists imr 4350 and 4831 as suitable for both. I got very good results with 4350, albeit in a 270win.
 
Varget isn't a good choice for 300 Win Mag, much too fast burning. Grab some 4831 or 7828ssc and you'll be set to load both cartridges with one type of powder
 
I would encourage your family member to buy his own ammo or use your loading kit to load his own loads. If he slips with rifle in hand and fills the muzzle with mud and then tries to fire the rifle only to have it blow up, who will he blame? He'd be better off with a 30-06.
 
That's the plan - I was just looking for more published sources to see if I could get away with using Varget or N140. However if I need to buy a new powder then I do see 4831 listed in both sets of data.

Use hodgdon reloading online.

They have 264winmag data ranging from 85gr to 156gr bullets

And the have data for the 300 winmag, 110gr to 240gr bullets.

IMR 8133
Retumbo
H1000
StaBALL HD
Supreme 780
H4831
IMR 4831
Hybrid 100V
IMR 4350
H4350

should all get you 3200-3300fps with a 120 gr bullet in the 264 winmag

Why do you ask? My post was a reasonable response to the OP.

Loading for others poses a bit of liability and a set of challenges. I don't do it and nor recommend it for others. Better to let the shooter learn how to load their own or cough up for the ammo they need. I've offered many times to show other how and let them use my gear and not once been taken up on that offer. This tells me that they are just looking for cheap ammo that they have nothing invested in otherwise.

Based on that, they would be better off with a 30-06 using cheaper factory ammo.
 
There's never a powder that's "optimum" in one cartridge for all bullet weights and certainly not for two, although if their expansion ratios are similar, you can sometimes get away with that.

That doesn't apply here, but you can always "make do" with a given powder, however then you have the powder dictating the bullet weight.

I agree that 4831 likely provides the best compromise.
