For the record. I used a 30-30 for 50 years on elk. All shots were under 100yds. Most were shot at bow range. I used the 170gr Partition bullet.
I feel this was very safe, and never lost an elk.
Now lets talk about the ranges the .243 will be, or has been shot at?
GM...Pretty weak, but it seems to be your pattern lately. Don't even try to claim your post wasn't aimed at me.
