Forgive me if this topic has been beaten to death, but I am relatively new to ARs. But given the numbers of hogs that we are seeing, I think the semi-auto ability might be appropriate. But I have a few questions:

1) 63gr Sierra vs 65gr Sierra BT. Any significant difference the the terminal performance? I have read good things about both of them...

2) Would a 350 Legend, or some 30cal or 6mm cartridge provide a significant improvement in terminal performance over 22 cals? DRTs are not essential. After all they are pests, not unlike roaches, fire ants, mosquitos, etc. The important thing is to remove them form the population. But DRTs are sometimes nice if you want to take pictures of your "trophy".

3) Any experience with FMJs? The rumors during the VN conflict were that they tumbled causing serious tissue damage. Anyone have any experience using them on pigs?

Again, my apologies if these issues have been hashed and rehashed. But I would appreciate any and all input! Thanks!
