I could shoot them when the shoulder was young and strong but I didn't need them then either. I just thought I did. The only thing I would hesityate to hunt with the 270- 7mm-08 is Grizzly and thet have been taken with those calibers as well. I like the 45-70 for really big critters. I can still shoot the Magnum rifles sparingly but there is no joy in it, just pain.
