One powder for .243, .270, and .308

[Revwildman]

Hi all,

I have a question that perhaps can't be answered ... but here's my attempt to try and streamline my reloading powders: Is it possible to find ONE powder for the following three calibers: .243, .270, .308?

Bullet weights would be: 75-85 grain for the .243 / 150 grain for the .308 / and 130 grain for the .270.

In the past I've had numerous powders on the bench, but am trying to eliminate it down to one ... hence why I am checking in with the experts.

I currently have W760 on hand, and just finished up my last bit of my IMR 4046, H4831, H4895, and IMR 3031.


So ... which powder would you suggest as the best one for the above calibers/bullet weights?


I am not into target shooting and most of my rifles have shot different powders well. My reloads are for hunting/plinking only.


Thanks everyone!

Sounds to me like your in the Varget range. The W760 is temperature sensitive, which is going to matter outside of 400 yards. The H4831 would be the old school powder for 270, but should be too slow for 308 family cases. Any powder you choose is going to be a compromise.

I use Varget for 223 up to 300 win mag,


try it you will like it!

H4895 is a nice powder to work with. But varget may be better for the listed calibers

 

[BigRobb]

Varget or possibly reloader 15.

Nosler manual lists imr 4895 for all 3. Might be best to try a couple diff powders. Rl15 for 243 and 308. 4350 4831 for 270

Hunting: IMR 4064, H380, H414, RL 15.

Plinking: IMR 4198, IMR 4227, Trail Boss.

I buy IMR 4064 by the 8lb jug. 223 up to 308.

Hi all

Ok. Thanks for weighing in here everyone!

So far it seems that the opinions lean towards Varget as the #1 choice, then 4064 & H4895 tied at #2.

I’ve never used Varget before. I’ll have to check it out.

Any other thoughts?

Reloader 15 and varget are close to interchangeable. Varget claims temperature insensitive. Reloader 15 is generally considered more consistent lot to lot.

 

[Revwildman]

Thanks BigRobb!

I’ve never used R15 either. Looks like I’ll need to check that one out too. Thanks for the temperature and consistency info.

Appreciated!

RL 17. I bought 8 lbs when wholesale was going under for 20$ apiece
Getting great results in my .243 from 55gr to 95 gr, and pretty good results in the 270 as well. Should work fine for the 308 too I would imagine.

Hi BBB
Ok. Thanks for sharing that. I’ve never used Alliant powder before. I’ll need to look into it.
Thanks again.

H-414
Its the same as W 760. And you say you have it on hand; try it, use it up & see if it fits your needs.
For what you're using it for, temp sensitive won't be a factor.

 

[Got Juice?]

Looks like Varget would be a solid performer.

 

[Ganderite]

Varget or RL15.

I would use RL-15 if I could only have one.

Prior to Varget I used a lot of IMR 4350 in 243 and 270 with excellent results. I am still experimenting with Varget and in 223 and 243 it is one of the best I've used.

 

[scott_r]

Varget for the .243 and .308 work really well for me. I dont shoot a .270 so cant comment there.

IMR 4350 , but in reality these are fantasy questions.........
