That sounds like great moose and brown bear meds! I love ballistics and really wish it was more convenient to shoot around here. I have a few good rifles but a two hour drive to a decent range.

You can only hunt with bow and shotgun here in silly New Jersey.
I wouldn't shoot much either, if I had to drive two hours

In the area I live, I can drive about 15 minutes from the house, and shoot out in the desert all day long

There is a very cool range about 30 minutes from my house. It is huge. I can't remember how many acres it covers, but it's a lot..
There is a dedicated pistol range, an area that has full size buildings for the Cowboy action shooters as well as training for LEO's.
There is a 100 yard rifle range that is big enough for a lot of shooters. Then there is another rifle range with targets ranging from 200 yards, out to 1,000 yards

That range is fun because at each 100 yard increment, there are full size steel Buffalos
That seems really foreign to me, to think about using a shotgun for deer hunting

. Have you tried Archery ? I've been hunting with a bow for awhile now. Next season will be 10 years. I love it. Very challenging... I've had deer and elk 20 feet from me, and they never knew I was there.
It's really cool to be that close, and watch and listen to the animals when they are not alarmed. The bad part is, even though I have been that close, there have been quite a few times that I still couldn't get a clear shot..
On seasons where I don't get anything, the hunt is still fun. I always have a great time with friends camping, and if I get to be close to animals, I still consider myself successful
... just about to start working up some handloads for my H&H, starting with Barnes and Woodleigh to see which I settle for. Oh, they are for Cape Buffalo, either should do the business but I will go with which I can get the best accuracy.
Now I'm jealous

I'm really excited about going to Alaska, and consider myself very fortunate, but going to Africa to hunt Cape Buffalo would be even better

Which Barnes bullet are you using ? I've never tried any of the Woodleighs, but have heard good things about them.
