RE: Loading for a 300 RUM
 

stubble, do you plan on trying the 200 grain accubonds? I am working with it now, I just haven't had the time to go shooting yet. Well thats not totaly true, I have spent some time shooting my new bow. Thats the problem of loving both rifles and bows, I don't have the money and time for both but I try my best.:D

I know Bigcountry uses 200 gr accubonds but I cant remember what powder he uses

RE: Loading for a 300 RUM
 

I have no plans to use any bullet heavier than 180gr in .308" as they just aren't required for any north american game.However,I do plan on trying the barnes tsx's very soon.

RE: Loading for a 300 RUM
 

That is kind of what I thought. I saw one person on reloadersnest.com using Rx19, and I kind of thought that might have been fast. Alliant's website recommends Rx22. I will see how it goes.

Think I use 90gr-91 of H1000

RE: Loading for a 300 RUM
 

BC, I had been told H-1000 is a temp. sensative powder. Is there any truth to that?

RE: Loading for a 300 RUM
 

All powders are temp sensitive. H1000 is part of Hodgdon's extreme line which says its much less temp sensitive than others. I do know that Alliants is very temp sensitive. I built this wonderful load for my 300Rum and RL25 when was 10 degrees. When I shot it in 80 degree day, it locked the brass up in my chamber.

That is why I do all of my final load testing at 60F to 70F.I lose a little velocity at colder temperatures,but the loads are safe in all hunting conditions.

Elkhntr. The Nosler reloading manual, 5th Edition starts with the 125 grain wt. bullet for the .300 RUM.
For the 165/168 grain bullets six powders are listed, IMR4350, H4831, IMR7828, AA3100, RL22 and H1000

For RL22 MAX load is 90 grains @ 3368 fps. Most accurate RL22 load was 88 grains @ 3312 fps. Also listed was 86 grains @ 3249 fps.

For H1000 MAX load is 98 grains @ 3335 fps. Most accurate load was 96 grains @ 3270 fps. Also listed was 94 grains @ 3198 fps

RE: Loading for a 300 RUM
 

For loading the stw's,ultramags and wby mags,the nosler manuals are poor choices as their loads are extremely mild compared to most other sources.In most cases their velocities are below those produced by factory loads.
