300RUM powder choices
Hi guys,
anyone out there using IMR4350 or H4831 as their powder choice for 300RUM. Our local choice of powders in South Africa doesn't give us much variety. Have been using a local powder B12.7 (equivalent to H870), but been getting huge variances between batch lots. Next possible choices are basically equivalent to above mentioned powders.
Want to launch 200gr or 220gr smk's from standard 26" Sendero.
Any load data would be appreciated.

Re: 300RUM powder choices
I think the 2 powders you listed will be too fast for these bullet weights. Try and find some Retumbo or H1000.

Re: 300RUM powder choices
appreciate the advise. Problem is that we can only get locally manufactured powder. My next choice is local powder S385 (equivalent to H4831) or S365 (equivalent to IMR4350).
Anyone use H4831 or IMR4350 to load up with ?
Cheers,
Paul

Re: 300RUM powder choices
Get the slowest powder you can then.
Check out: http://www.hodgdon.com/data/general/burnratechart.php
You can see where the powder you are considering is in relation to the powders being suggested to you. A fair amount of difference generally. I did use VV N560 (equivalent to N160 in burning rate, I understand) in my 300RUM which is closer to the speed of powder you are mentioning--pretty close to 4831 actually. If I recall, I was in the high 80's for grains of powder charge and around 3075fps or so with the 200AB. Start low and work up as always. I like what I'm seeing with US869 much better and the 200AB.
