I got rid of mine,the twist mostnormally used does not let you load heay enough to get a reasonable trajectory and good accuracy at the same time in my opinion so its difficult to go much beyond 100 yds.
On the other hand a long barreled 54 cal with a 1-70 twist which is readily available with a heavy load will reach 150 or 175yd and down anything on this continent;you have to place your shot no matter what you use.
