Not really, only have about a dozen. Bought my first one in 1978. I don't necessarily hunt with them as age and health limit me to hunting only a couple of times a year. I do like shooting them, especially with reduced loads. If I want to check the accuracy of one it's 57 grains of IMR4350 and a 150 Sierra FB or a 165 Ballistic tip. Like Hanco, his favorite load or mine will take care of anything I'm likely to run across in Middle Tennessee. It's been a long time since I've seen a Mastodon or even one of those Terrasaurasis or whatever they are in Tennessee. I believe it's with us to stay.
Take care,
Rick
