One powder for to calibers

[Lone wolf]

Hi guys is this possible, I'm about to gear up for loading for 22-250 and a 6.5CM so I have been looking and hoping that I can cover both calibers with one powder

Will be shooting 50g from the 22-250 and 90-130g in the 6.5

It would be convenient if one powder would cover both

RS52 might work for you.

Download as many load data sheets as you can from different manufacturers.
Read through and you will find a favourite.
I came to Ramshot Tac for .22/250 and .308.
But use Hunter for my .243.

 

[Miki]

You've got a relatively light bullet in the 22cal and a heavier lump in the 6.5
The lighter bullet can be accellerated faster and reach a faster velocity than the 6.5
The 6.5 needs a slower burning powder so as not to exceed the max pressure. I guess you could use a slow powder with the 22-250 and reduce it's MV, but why would you do that ?

Which internal ballistics software are you using ?

 

[Selous]

I agree with @Miki. You may find one powder that will do but is unlikely to be ideal for either round. To me the squeeze isn’t worth the juice!! Stop being a tight arse and buy a tub of powder that is right for each calibre!

RS60 works for me in both calibres.

A quick look here Viht powders suggests N140 or N150 are common. You would need to check to see if they are giving the performance you want.

Be aware though that Viht powder maximums shown are notoriously conservative. Other producers may well be similar but I have less experience with them

Thanks buddy I will look at that

Thanks mate I've been scanning through my Lee reloading book and there are some powders for both, but hopefully someone has a proven recipe

Good point on bullet weight, new to reloading so I had it in my mind I might be able to load the 22-250 near its max load and the 6.5 in a similar way.

Internal ballistics software? I have strelok pro or is this not the same sort of thing?

I know I am being tight, I like to get my money's worth, it may just be the way to go and get a powder for each caliber.

In reality I'm not going to buy both rifles at the same time so I could just focus on the one I buy first

RS60 works for me in both calibres.

Cheers dave I will look into that, out of interest what bullet weights and powder weights are you running in each caliber

Cheers mate thats good to know will look into that.

Thanks to all I appreciate the input, its probably best if I just get a powder for each I suppose, but at least they both use LRP

No, Strelok is an externall ballistics tool.
QuickLOAD is a popular tool as is Gordons Reloading Tool.
here is a snapshot of my GRT calcs for my T3 22-250 with a 50gr sierra SP bullet.
These cals are based on my rifle, my OAL etc and will likely NOT be suitable for your rifle..

Ah I see, thanks for this I will download it and have a play

While you could use one powder for both, it will likely be sub-optimal in both cases. As has already been explained by Miki, you need different burning characteristics. Both will fire, but not burn all the powder perhaps and be inefficient and dirty.
I'd recommend looking at N130/133/135 or RS40 for the 22.250, and N550 or 160 or RS62 for the Creed (poss RS60 would be better for the 95gr)

 

[Bowland blades]

Don't ! many reasons why 1. the powder used will not be totally perfect for both frequently 2. if that powder becomes difficult to get , you have a lot more trouble replacing powder in a hurry can think of many more reasons just think on carefully as your compromising with only say £50 at the till one time

 

[Stevie/P]

Not the OP calibers but one powder does work extremely wall in two different chambering’s is N160 was my go to load in 6.5x55 and also in my .270 Winchester.

its also good in 243 , 6.5 creed , 260 rem and much more

 

[Dave_45]

@Lone wolf i used 53-55gr copper in the 1-8 22-250
6.5 284 I use 95-108gr ,gs custom and hasler ariete (very very good non lead bullet)

 

[GWP]

Varget is the one you want shame its not available but n140/n150 is a possibility

 

[imnotrucknut]

I use rs60 for .243 3006 and 6.5cm.

A powder which works well in one of your calibres will be mediocre at best, in the other. N135/140/540 will work in the 22-250 and N555 in the CM.
