BUFFALO BORE PREMIUM SUPERCHARGED 243 WIN. AMMO
The 243 Winchester cartridge is a very useful and versatile cartridge for almost anywhere in North America, which is why we are making a huge selection of loads for it.
When I turned 15, (I’m 59 as of the date of this writing—02-07-18) I bought my first 243 Winchester rifle……..a Browning BLR. By the time I was 17, I had two of them. I never fired factory ammo in either of them, but used only my hand loads. When using purpose designed ammo, the 243 Win. is good for "grenading" small critters like woodchucks, for collecting pelts on foxes, coyotes or wolves or for hunting deer sized game animals. My 243’s spend a lot of time riding on a four-wheeler or hiking with me. I’ve killed black bear and deer with them. I long ago lost track of how many rock chucks and crows have been blown to smithereens with them and if I am in a particularly bloody mood, tree squirrels can be vaporized into nothing more than wet spots on surrounding branches, if you use the right type of ammo.
I do not advocate hunting elk sized animals with even the best 243 big game loads, but it could certainly be done. One of my hunting buddies that grew up in the Salmon, Idaho area, was given a 6MM Remington for his 16th birthday and like most ranching kids, they make do with what they have because ranchers do not spend a lot of money on frivolities like multiple guns. From the time he was 16 till his late 40’s, he killed his bull elk and mule deer, each year with that 6MM Remington, which for all practical purposes is a 243 Winchester ballistic equivalent. He killed 30 bulls with that 6MM rifle before he broke down and bought a much more powerful elk rifle. HE NEVER LOST ANY BULL HE SHOT in all those years because he understood the characteristics and limitations of his rifle/ammo and stayed within them. If he could get within a 100 yards, he would head shoot them, but if he could not get that close, which was normally the case, he would wait for a double lung shot and put a 100gr. Nosler Partition hand loaded bullet through both lungs and let the bull run about 50 to 150 yards before piling up.
The light recoil and great accuracy of this little cartridge allow the shooter to do a number of fun chores with it. Ammo selection is critical for the job at hand. We will eventually make the following 6 different loads.
1. Item 43A — 55gr. Nosler B. Tip @ 4,100 fps
2. Item 43C — 70gr. Nosler B. Tip @ 3,650 fps
3. Item 43D — 90gr. Sierra FMJ Spitzer @ 3,300 fps — “PELT SAVER”
4. Item 43E — 85gr. Barnes TSX @ 3,350 fps
5. Item 43F — 100gr. Sierra Spitzer flat base @ 3,150 fps
6. Item 43G — 100gr. Nosler Partition @ 3,150 fps
This particular write-up is regarding our item 43F. This load features a 100gr. Sierra Spitzer bullet at around 3150 fps from 24-26 inch barrels. This is a multipurpose load for the 243. That 100gr. Sierra bullet is soft enough to expand on small coyotes and foxes (especially at close range) but tough enough to give sufficient penetration to hunt larger deer or medium hogs and black bears. I would not tackle animals that weigh more than 300 lbs. with this bullet. Also, it should be noted that if you whack a deer at 50 yards, that bullet is quite explosive and therefore will not penetrate more than 14-18 inches, depending on which bones are struck, etc.. However, if you shoot deer out past 250 yards, that bullet, now moving more slowly, will expand less violently and will penetrate much deeper. Every load used in every rifle will have trade-offs. The trick is to choose a load that will do what you want most of the time and then operate within those limits. I like the 100 gr. Sierra bullet because it is quite affordable and works well for many applications. If the sole purpose of my 243’s was deer or big game hunting, I would use the 85gr. TSX or 100gr. Nosler Partition, but I do not normally hunt deer with a 243, so using the 100gr. Sierra for whatever I happen to encounter (normally coyotes, crows or Rock Chucks) is a great choice, especially should I decide to hammer a deer or black bear in the process, but remember, this bullet has its limitations on bigger animals, depending on the range/velocity you hit them at.
These are the velocities from my personal rifles. Note that I like short barrels because I am normally carrying a 243 in a truck or on a four-wheeler and getting a short barreled rifle into action is faster than doing the same with a long barrel. You can generally add 100-200 fps to my velocities if you are shooting a 24-inch to a 26-inch barreled rifle.
