I grew up using a smei auto .243 for deer. Now i live in PA where we cant use smei autos. I still have it for my yearly trip to my moms house and i also got a semi auto .270 for when im there for the longer shots. All my bolt actions are more accurate but it wouldnt be enough to make them better for deer hunting out to 250 yards. If i had to shoot farther id rather not use a semi auto but i like them.
