Looking for suggestions for some good loads to work with. Have good supply of H450 and IMR 4350, so I don't have to worry about powder availability for a while. Thanks

ajax, get your manuals out, and with the powders you list, figure on heavy (160 gr +) bullets to take advantage of them. Take a look at the suggested loads and apply them to your rifle, then work up your loads. There is no such thing as a perfect load across the board, which I'm sure you know, so have some fun & find your sweet load. But pay attention to the manuals - ignore them at your peril... :cool:
Cheers,

I believe I hit you on another thread on the same subject. My experience is with H414 and H & IMR 4350. They are all nearly identical with regard to burn rate. Single base 4350 is definitely more bulky. I found H414 just easier to load. Had to use a drop tube to get the load of 4350 into the case and it was still compressed, which is fine. Just easier to use a spherical powder. At any rate, in these burn rates, my rifle liked a max load. Gives some stellar groups with the 140gr bullets.

My experience with my '95 Mauser has been that H4350 (even at the starting load of 40gr) behind a 168gr Sierra Matchking is a fairly stout load. Very accurate, though, at 100 yards (more so than I'm capable of holding). Play around, and have some fun. But, as mentioned above, always stay within the recommended charge data, especially if it's an old rifle.
