Well I have found that it is a pretty forgiving caliber to load for. In some 20 years with it I have loaded bullet weights ranging from 100grs up through 160grs, and have hit at least a couple of very accurate loads in every weight.
This said, I have mainly stayed with powders ranging from 3031 through Ramshot Hunter on the burn rates, but have found a couple of nice loaded with a couple of even slower powders.
My mainstay loads for my rifle are using the 130gr bullets for the most part with a couple of 150gr loads in for good measure. Probably the most accurate load has to date been with 46.5grs of IMR-3031 under the Nosler 130gr BT for around 2750fps from my rifle. It sill simply cluster the bullets into a nice quarter sized ball at 200yds day in and out. It's not fast, but it need not be, it has preformed well on deer and hogs out to 400yds with outstanding results.
Stepping up the velocity a bit I also have found that the 130gr SST over a good dose of Ramshot Hunter will really preform, almost up to the accuracy of the above load, but it is getting just over 3000fps and really rocks out at the extended ranges where the other one leaves off.
With the 150gr loads I have primarily stayed with a standard medium load using either of the 4350's and simply worked it to a range between 2650 and 2800fps. This is easily under 1" at 100yds and usually around or just a pinch over at 200. I started using it simply due to I had several hundred 150gr RN bullets of several makes given to me and I hated to see them just sit there. They are used for hog work and with the low velocities and recoil they are very good at the task. I wouldn't hesitate to use them on anything else of bigger stature, where close quarter shots might come about, like elk in dark timber.
Hope this helps, but if your like me, you will probably find that there are simply too many powders that will work very well and a few that are exceptional with this round. The end result will be what your needs are going to be, in determining the bullet weight or velocity, and then going on ahead from there.
