[lightmag]

going out to buy powder tomorrow, loading 180 gr bullets in a browning x bolt 300 WSM any suggestions on powder? any preference/info on the following 3 i'm thinking of buying?

H4350

IMR4350

reloader 17

if you were picking 2 which 2??

thanks again

Either of the 4350s will work well.

I am less than impressed with the RL17. I have tried in in my 300WSM, 30-06 and 270 Winchester. In the Short mag velocities were a bit higher than I could get with other powders but accuracy was dismal. I then tried it in the other two cartridges and velocity was no better than what I could get with IMR 4350 or Reloder 22 and again accuracy was poor.

I have great results with IMR 4350 with both 165 gr. and 180 gr. bullets. Also tried IMR 4831 it gave very acceptable results as well. IMO H-4350 and IMR 4350 are pretty close and so if you want a second comparison powder, I would only get one of the 4350"s.

if i want to try a RL which would be best then 17, 19 or 22?? all have been recommended to me???

had good results with Imr 4831. 4350 was good as well. I have a surplus of 4831 so it is what I am using. A friend is using RL15 with decent results. my 4831 handloads for his rifle are more accurate. he is in the process of changing over

I use H4891SC with excellent accuracy in my Ruger .300WSM. Although I only use Barnes TTSX in 168 grain...

You should have very good resuls with RL-19 and IMR4350 w/180 grain bullets.
Personally I'm gearing up to try my first 3 llbs of RL-17 but as of yet I know squat about what it's going to do out of a 24" bbl.

RL 19 works well for me and using the same OAL with less powder in RL 17 gave me about 100fps more with the same accuracy. I found that the rl 22 is too temp. sensitive to give consistent piont of impact when the summer comes around.

Correction H4831sc

I have had spectacular results with Norma MRP in my 300 WSM, sub-moa accuracy and top velocities for this stubby case. Eagleye.

If I was going for 300WSM powder testing, I won't left Win760 out of the equation!
I've tried IMR 4350 & 4831 also, accuracy was there but velocity was not, in a Browning 23" barrel.
W760 gave me accuracy & velocity.
This spring, I've got some RL-17 to try, can't wait!

 

[BCboy]

I went with IMR4350 or IMR4831 and had had great results with my 300wsm

RL19 gives great results for me out of a 16.5" barrelled ruger frontier
( 180 grainers)

IMR4350 still under an inch

If you want another suggestion to add to the mix, I have had great luck with H414 in the short mag.

 

[daniellybbert]

I use Imr 4350 or RL 19 in my kimber montana

 

[skidderman]

RL22 all the way. Tried H414 and it was two hot.

 

[killman]

Seems you will probably be using these in temps from 20C to -20C I would be looking for a powder that isn't very temp sensitive. Something from the Hodgson extreme line maybe?

 

[nelly250]

I've only tried H4350 and H414 - both with great results.
