Anyone still load for the harret? I've got a 10 inch contender and all the new load books are loaded light. I don't want to stretch the frame but I do think I can push my 180 gr xtp load a little more . Currently running 4227 and getting 1900 fps. I do have 1680 also. I'd like to use it for elk at close range here in Arizona.
 
QL data attached. Not sure if you were referring to H4227 or IMR 4227 so I ran both. None show 180 getting to 1900 fps within pressure limit.

Thanks for the data. I'll have to see what I loaded it with. My dad said they use to
load them hotter and some of the old books from the late 70 early 80 are loaded much more than the current books. I do know it's hard to tell when you've got it to hot 🔥. As your stretching the frame before you truly see pressure signs.
