Thanks Shilen 30 I will try the H4831sc next time I buy some powder. Somewhere I have some 220gr.(?) MK's (about 10 or so). I was given these after a PS article about how accurate these were. I haven't tried them yet.

Some guys like the 220 SMks, some don't. I know one guy that is a good 1000 yard competitor and he loads around 70 grains H4831SC with the 220 MKs. Others I have talked to say they work best in the faster cartridges like the 300RUM. Compare the BC on the bergers and you'll see that the lighter stuff will have the same BC as the 220 MK, you just have to pay more for them. If you get the bergers, you may have to seat on or soft seated in the lands.
