That's a really good load David.

It's a mid-range load, but penetrates very well. I use that one all the time with both the 250 gr 429421, or a 300 gr wfn cast. The 300 grainers do 1070 from my 6" guns, and the 250's will run around 1100-1125.
The fact that the 300's do almost the same as the 250's is another reason why I like the heavy bullets. Fast follow up shots with a bullet that has the necessary weight and momentum to keep on plowing.
