This .243 has been in my family since 1969. Dad bought it for my brother and me to hunt with as we had complained many times about Grandad's open sighted 30-30 carbine. While I admire the 30-30 cartridge, it's range limitations are frustrating for hunting the open prairies of Wyoming.
When we shared this rifle for hunting, it went like this: 1st day, I'd carry the rifle and my brother would help me spot game and drag the dead animal out. 2nd day, he would carry the rifle and I would provide same support. It was a system that worked well for us.
Up until the mid 1970's we hunted with FEDERAL 100 grain ammo because it shot so well and always got the job done. Once I began hand loading, a constant experimentation has ocurred.
I need to clarify the mule deer hunting situations most likely encountered. These are actual shots IÂ’ve made or seen made on large mulies:
1) canyon country with open wooded terrain; distance to quarry may be
from 125 to 200 yards
2)open prairie grasslands with rolling hills; distance to quarry may be 125
to 325 yards.
3) region of large flat topped buttes dotted with juniper, sage, and cactus;
distance to quarry may be 125 to 225 yards
Clearly, an accurate rifle and an accurate rifle-man is required. Caliber and cartridge choice is not critical. But with a lighter caliber such as .243, premium bullets are the best choice. Premium bullets such as the Nosler Partition will provide an exit wound. Very important in this terrain because lack of a blood trail at dusk could mean leaving a fine trophy outdoors overnight to be consumed by hungry coyotes before we could return the following morning.
The .243 has adequate power and flat trajectory to hammer any muley that ever walked, assuming good shot placement into the lungs. But I strongly recommend premium bullets such 95 grain Nosler Partition. The Hornady SST is reported to be quite good but I have no experience with it.
Stacks of mulies and ‘lopes have fallen to our old Remington pump gun in .243 Winchester. Accurate shot placement combined with a tough constructed bullet kills effectively. But I’ve killed a number of deer and antelope with FEDERAL’s 80 gr Sierra Pro hunter. This bullet is very accurate and very fast but does not produce an exit wound. I do not recommend this bullet for late afternoon hunts.
The most important factor for a first time western hunter is accuracy. Which rifle do you shoot best? Moderate recoil rifles are much easier to shoot well for vast majority of people. This is why the .243 is a popular seller and .257 Roberts refuses to fade away. YouÂ’ll need to hit a target the size of an empty 1 gallon paint can at ranges exceeding 150 yards. Typically, I shoot from the sitting position or prone. You can expect the same. You may find using crossed-shooting-sticks helpful. A good choice for steady aiming from the sitting position.
I hope this clears up any misconceptions you may have about your .243 for mule deer hunting in western South Dakota, Wyoming, eastern Montana, or the prairies of Colorado, North Dakota, and Nebraska.
