IMR 3031/150gr loads.

I am going to purchase some IMR 3031 soon to use with 150gr bullets for my 30-30. Does anyone here have a favorite load with this powder they can share. I know the time tested favorite load with this powder is 30gr under a 170gr bullet. However my rifle prefers the 150gr variety, at least in factory form anyway. At the moment I have Hornady, Sierra, and Speer 150gr bullets on hand. Also has anyone here used the load data from www.realguns.com for this powder? Some of the loads I looked at for IMR3031 appear to be a little on the steep end for both 150gr and 170gr loads.

Lee lists a start load of 29.5 gr and a max of 31.1 with a 150 gr jacketed bullet. I would start at the start and work up to either a sweet spot or a pressure sign and if it gets too steep start at the start again and work back down a little bit and see if the sweet spot is down there.

When using info off the web remember that some folks dont have a clue what they are doing or writing about, and others have developed loads that are stout but safe in their individual gun and seriously dangerous in someone elses. If in doubt use published information from safe sources.

336A,
I just checked my records and it seems that I bounced from 31.2grs to 32.0grs of 3031 with the 150gr bullet. Not sure why I did this, but I think it depended on which loading manual I was looking at when I loaded the ammo.
The last ammo I loaded with IMR 3031 was loaded in 2004, and my lists go back to 1984.

30.0 grains under the Speer 150, used to be my favorite, but I found better accuracy with Re-7.

Maybe I'm a wimp... I always got good results from 28.0 grains

I use 30 grains of IMR3031 under a 150 grain cast bullet GC for just under 2,200 fps.

Thanks for the help folks. I have figured that since I have had miserable results with W748 and RL15, I might as well give the traditional powder for the cartridge a try. It appears that more often than not, the results most folks recieve are good to very good with this powder.
