So, you're telling me you would have no problem hitting a 5-inch target at 250 yards with your Marlin lever action in .357 with factory irons? That would definitely earn you some bragging rights.
And, 400 yds on an 8 inch plate with the 45-70 with just your average 4x hunting scope with plain duplex reticle is definitely worth a gold star. Me? I have to have a gridline reticle or adjustable turret (with ALOT of adjustment) to do it. That's a huge amount of drop at that distance.
Give me a Burris range finder scope at 4x and I will shoot pumpkins all day long at 400 yards.
I have seen guys hit a squirrel at 300 yards with a 357 lever action routinely. I hunt with them regularly.
