I ordered them from Cabela's online. In fact I just ordered another two boxes. These things load like a dream and are not all that bad in the recoil department. I sure like the way they group too.

I have shot those two bullets you mentioned. The 440 grain did not work for me at all. In fact I ordered a box of them and still have some left. I am debating whether to melt them down for other bullets or just shoot them off for fun.. They just would not group the way I wanted unless I went with a real low, and I mean low charge. The 450 grains did all right. They are just a real pain to load because they are so long....
