When I bought the gun he also gave me 44 loaded round's.The round's are loaded with 90gr of H870 Win LMR primer's and 150gr Ballistic tip's.Ten shot velocity is at 3274.And two five shot group's a touch under an inch.I wonder what a 162gr A-Max will shoot like out of this gun???

Try using the H870 first and see how you like it.
The WC872 is just a bit slower then the H870 but, not by much.
Either powder will give you longer barrel life because of the additional graphite. Both are very good powders for the overbore cartriges.
Try 85 to 87 Grs and the 168 Gr MK and you no doubt, will like it.
Use a Mag primer like the 215 Federal.
I have been able to get the WC 872 and have sold at least 1400 lbs of it over the years to hunting friends that live close to me here in PA. I won't ship any and my supply is getting hard to get now.
