. I'm Steve. The flip side to this is a much wider trajectory deviation beyond 200 yards. After all, this is the distance that most rifle ranges are geared to let you practice. First, find a good balistic calculator, just google it. With this in mind I was having a chat with a fellow hunter on a cull earlier in the year, he was using 100gr softpoints and reckoned that zeroing at 1 inch high at 100yds would give him bang on at 200yds. Can be checked in the field before I get a hard time but that means you have a little over an inch drop at 200 yards then obviously is shooting an inch high at 100. What size groups should I be looking at being acceptable? Its no secret that I love the .243 Winchester caliber rifle cartridge.

Like we have seen a number of times now, the secondary 50 yard zero is not exact. Gravity is relentless. Twist Rate's Impact on Ballistics The reason we want to figure out that MPBR is so that we know that out to a given distance, we dont need any fancy dials or trajectory charts to help us kill game. A nice scope is worth every penny. . TBRW - 200 Yard Zero TBRW Group. even if your expected quarry will be inside that 90% of the time. This is what we mean by "flat shooting." When I learned the 50/200 it was for M4 and or carry handle iron sights and then Red Dots. Elevation Windage . At zero yards your rounds will hit about 2 inches low because of your offset, or the distance between the height of your sights in relation to the bore. The bullet does not drop below the speed within the max range specified. What does that mean? Don't believe me? The point blank range for a deer, for example, is generally regarded as six inches. And at that distance, youd better be looking at a broadside animal thats not moving, because the kinetic energy of your 100 grain .243 bullet is down to 880 ft. lbs. 6.5 Creedmoor VS .308 Winchester (Ballistics and Accuracy). Even though the 30/06 case is about 24% longer than the . Maximum 4572 meters; Minimum 0. Each ammo shoots differently. %%EOF Pug wrangler.

Other riflemen who routinely hunt areas where shots of 300 yards or more arent uncommon sometimes opt for a 200-yard zero. #1. on a personal note and from experience with 243s and AI I alwasy zero at 200 yards,although I only use a 70 to 80 gr bullet,if you use a ballistic program correctly IE putting real time data into it,bullet weight,bullet BC,FPS,scope higth above bore ect ect,the good programes like Exbell will give your optimun zero range in my case its 214 yards to hit a 2 inch target, it amazes me how many people "set up at 1 inch high" at 100 yards and havnt got a clue where the bullet will hit after that distance,there is no way on this planet a 243 shooting a 100gr bullet set up 1 inch high at 100 yards will only drop 2 inch at 200 yards, if you havnt got access to a chrono or a proper ballistic programe why not test the old fashioned way by setting target boards up at various distances as its no good guessing when shooting living animals, if anyone has there data I can run the numbers on exbell just to show whats really happening. #3. Input your hunting conditions to see the drop, drift, bullet trajectory, velocity, and energy in easy-to-read ballistics charts and graphs. So i guess if i was to put them an inch high at 100 yds, then i would be a tad under 2 inches at 225, so basically within a normal kill zone when point and shoot. Round-nose bullets throttled to 2,700 fps or so (.22 Hornet, .25-20 Win., .30-30 Win.) Sighting-in a hunting rifle to hit a certain number of inches high at 100 yards (or 100 meters) maximizes the point blank range of the . God knows why, I always go for the heart at that distance and very rarely miss it, so the head should be on, I'm just not easy with it! This bullet really performs well up to 200, 250, and even 300 yards having a drop of just 2.7" (2 and 1 half inches) at the 200 yard mark. Buying a common caliber, like the 243, is a good idea. At that distance youd be able to get the best maximum point blank range in yardage of around 300 yards (296). As easier way to start this process is with an online ballistics calculator. Steve has been a hunting junkie his entire life. While I think the 50/200 yard zero has its merits, I think a lot of folks hold it in very high regard while also holding some misconceptions about it. The problem with a 50 yard zero for a .243 is that the MBPR falls off pretty significantly. i use 100gn siera gamekings in my 243 doing about 2950fps, for stalking purposes I zero at 150yds, I use it at the range quite a bit and have played about to see how much a bullet drops, zero at 100yds then moved back to 200yds and the bullet drops between 4 and 5 inches, then at 300yds it drops about 8 more to 13 inches, not tried 400 or 500 but at 600yds the bullet drops a total of 88 inches, i suspect this is not a chroned 2950 as taking the middle ground of 4 1/2 " low at 200 seems to great a drop from a 150 zero. By no means an obscure cartridge, many manufacturers produce the 243 Win with every conceivable bullet type.

I didnt notice the ambiguous terminology until you pointed it out. Perhaps more interesting, is that a 50 yard zero doesnt even come close to providing a decent secondary zero at 200 yards. Now when you go back to Georgia swamps, you might consider re zeroing at 100 yards for making head shots at shorter ranges. It also maintains enough kinetic energy (killing power), to remain an ethical and effective deer hunting bullet at that distance. I simply see the animal, range it and shootout to 310 yards. Popular among metallic silhouette and long range shooters for its low recoil and high accuracy. It is possible to get pretty close to a 200 yard zero while using a rifle zeroing target at 50 yards.

So from 0-300 yards, for instance, we aim at the dead center of the kill zone on a deer, and no matter how far it is away, well hit the vital areas. The bullet energy is comparable, but the weight makes a difference in stopping power when it . All data created using our free ballistic calculator. Of course thats all fine untill you factor in uplift from ground rising and wind chaneling etc,etc. In real world use on deer that is point and shoot out to 200 yards. 3rd rock from the Sun, CDB land(Mt Juliet). 9566 0 obj <> endobj Plenty good enough for boiler room shots but if I was to contemplate head shots at 100 yds I would reset the scope to be spot on at that distance. That said there is still some truth to the claim that the 50 yard zero can be used to engage a target out to about 250 yards without having to worry much about making an elevation adjustment as long as the target larger than the projectiles trajectory deviation plus the precision deviation of the cartridge and rifle combination. For example, assuming we can consistently shoot 1 MOA groups with rifle and cartridge at 250 yards the smallest engage-able target with the 75 grain load would be about 4.63 (2.13 for trajectory deviation plus a 2.5 group size) in diameter. start with bore sighting it. 48. While the 200-yard zero does carry bullets to about 235 yards before they fall 4 inches from point-of-aim, it also puts 4.5 inches high at 100 yards to 125 yards.

Altitude: 0 Feet with a Standard Atmospheric Model. Zero magnification. Developed in 1976 by Ken Waters as a wildcat cartridge, the 7-30 Waters is based on the .30-30 Winchester necked down to 7mm to improve velocity and trajectory, with a significant drop off in felt recoil. Starting at 2700 and 2600 fps respectively, their velocities maintain about 100-200 fps difference all the way out to 1000 yards. Any farther, the bullet drops to -5.0 at 225, which would result in either a miss of a very low hit on deer-sized vital areas. Pro's: this affords the shooter the longest range.

Zeroing a rifle at 50 yards and assuming the secondary 200 yard zero will be usable is a mistake. ok a lot depends on the setup but for the bullet traveling at a mv of 2950 thats a heck of a lot of drop over 50 yds. For some calibers, the bullet will drop 2 feet from a 200 . Thats my current opinion (which is outdated after looking at more zero distances and the maximum point blank range concept covered in this other post) based on analyzing a bunch of external ballistic data like the data presented in this post. If you cant hit the dime at 26 yards, it indicates that your rifle (and/or you) probably isnt accurate enough to be shooting at long range anyway, because if your rifle is grouping 1-inch at 25 yards, for example, it will likely be 4 inches off at 100 yards and well off the paper at 300.
