Zeroed at 50 yards, the 1 ounce slug should hit 4.6" low at 100 yards. You are correct that the slug is on an upward trajectory at 25yds and that's why it is high at 50. Although there are many different slug rounds, as they are more for the distance they are generally tapered to some extent and made to have the aerodynamics of a bullet. Dunno where I got 20. It states that a typical 12-gauge, 1-ounce slug traveling at 1,560 fps loses 60 percent of its energy at 100 yards. The final turret is tuned to 20 gauge slugs or a 300-grain muzzleloader bullet pushed by two blackpowder pellets. Federal Rifled Slug 12 Gauge The Federal Rifled Slug is an outstanding slug choice. BTW, you didn't say it was 12 gauge but most folks concerned with shotgun slug shooting choose it so I made the assumption. Im probably going to set my zero at 100 yards. The 50/200 zero variations and the 100 yard zero work well because they have been tested and had various bugs worked out. Whenever you sight in you will be dead on at two distances and either high or low at all others. In the not-so-distant smoothbore days of slug shooting, people bragged about shotguns that could hit a It looks like it is still rising even at 50 yards. Okay so I found a trajectory chart of the Hornady SST 20 gauge. The same methodology is true from the 4 gauge down to the 28 gauge. A 12 gauge is all fine and good for a person used to recoil, however it may be prudent to have a 16 or 20 gauge if your wife, daughter or SST slugs feature the patented FTX Bullet with a sharp point that increases the ballistic coefficient, allowing it to fly faster, farther and on a flatter trajectory. I have a H&R Ultra slug hunter 20 gauge. Even a 10-mph crosswind can move a slug 5 to 6 inches over 100 yards. As the above ballistics prove, a 12 gauge slug has a flat trajectory out to about 150 yards, so if you are a good shot with an iron sight, then you should be good to go. My calculation based on that BC gives me an 85 yard zero with the slug at 2" high at 50 yards, zero at 85 and 2" low at 100 (and dropping about an inch every 5 yards from there on out). At 100 yards any brand of it will kill anything in North America it hits well (shots in a Brown's foot don't count). Although its ME is 2,365 ft. Available in 1-ounce and 1--ounce options, you'll be thrilled with the power these loads bring to the target. In general, yes, the 20 gauge is the better platform for rifled slug guns for deer. There are no clear standards in rate of twist for 20 gauge slug gun barrels, either, ranging from 1:24 and 1:28 to 1:35 or so. Concepts such as what youre promoting are akin to the military 25/300 zeros that allow for a person to miss head shots as close as 100 yards because of the higher allowed maximum ordinate. Although its ME is 2,365 ft.-lbs., it drops to less than 1,000 ft.-lbs. As stated the recoil of the 12 is something you will have to deal with. 20 Gauge Sabot Trajectory. A shotguns gauge is determined by the number of round projectiles of equal diameter that can be subdivided from one pound of lead. The angle of departure (for small arms generally very small) is formed by the intersection of the line of departure and the baseline. All ballistic gelatin blocks used in this evaluation were nominal 10% ballistic gelatin blocks calibrated in accordance with FBI RFP-OSCU-DSU1401 as follows (FBI RFP-OSCU-DSU1401, page 95, 2014): The SST Shotgun Slug has unmatched long range accuracy delivering true 200 yard accuracy and sub-2" groups at 100 yards. On impact, the Flex Tip initiates expansion at all velocities. Note: the Raptor Alv/Lead 270gr data uses a 150yds zero and the drop looks much better than the 365gr Copper slug at 200yds. I'm shooting a Savage 20 gauge Slug gun. I suspect an iron sighted slug barrel would be better served with a 75 yard zero. The Winchester Ballistic Calculator allows you to select your Winchester product and view the real trajectory from that product. speed/power of a slug, and wonder why they missed. I have shot 1000s of shotgun loads and still cringe when the recoil of a heavy load magnum is absorbed by my shoulder. Recommendation: If the farthest distance that you ever plan of shooting your rifle is 50 yards then you might entertain the idea of the 12-yard or 15-yard zero. At 150 am about 3" low. Calculated trajectory: Current indications show the 270gr Raptor Alv/Lead high performance slugs @ 19oo+fps may be the heaviest weight slug usable at those velocities.. Though twenty gauge shell itself is woefully lacking in standards, 22 24 inch barreled 20 gauge slug guns appear to be the most popular. at 100 yards, which is below the minimum recommended energy threshold for big game. Moreover, compared to 12-gauge sabot slug loads, 20-gauge slugs are much less punishing to the shooter and much flatter shooting, making trajectory considerations for a 200-yard shot with a sufficiently accurate gun/load combination much more reasonable in the field. it appears to me that 1" high at 25 yards would be a bit too high for a 50 yard zero. Logged coelacanth. Taking a look at the components for the Hornady SST Sabot Slugs for the 12 gauge. The worlds best MSR 15 cartridge just got better. Click to Jan 28, 2003 Messages: 11,188. What is the effective range of a 12 gauge slug? Using that measurement and the calculator I linked, the trajectory it plots seems very feasible. You are far better off to zero at 50 or more, the closer you zero in at the worse that problem could be down range. The redux of the Browning A-Bolt slug gun is in 12 gauge only, so if the A-Bolt is what you want you don't have a choice of gauge. Published in 1964, the "Fact Book" states that a typical 12-gauge, 1-ounce slug traveling at 1560 fps loses 60 percent of its energy at 100 yards. Meet three new loads that get more from 224 Valkyrie. If the slug begins to tumble in flight, drag will tend to push the slug back into straight flight. Foster slugs may also have rifling, which consists of 11 or 12 fins either cast or swaged on the outside of the slug. Buckshot terminal performance at 0-100 yard distance: Maximum Effective Range of Buckshot Impact velocities used in this report were obtained from an Oehler System 85 using no velocity corrections. 12 Gauge Foster Slug Trajectory @ ~25yds. Maximum effective range is limited as much by the slugs rapid decay of energy and velocity as by its poor accuracy. Published in 1964, the Fact Book states that a typical 12-gauge, 1-ounce slug traveling at 1560 fps loses 60 percent of its energy at 100 yards. Out of a 20" barreled 870 I am slighly high at 50 yards and slightly low at 100. The results - they grouped nearly as well as the Federal Premiums (1.5 inches @ 50 yards and 2-3 inches at 100 yards). Gave another slug a try - the Winchester Supreme Partition Gold (12 ga, 2 inch, 385 grain, 1900 fps High Velocity). Having grown up shooting 12-gauge Foster slugs at deer (emphasis on the word at), I was happy to see there was a new cartridge providing plenty of energy and a flat-enough trajectory to handle most deer hunting in the eastern United States without the abusive recoil of a slug gun or one of the big .40-plus straight-wall rounds. Compare up to 4 Winchester products and see how they compare. I zero my slug gun at 75 yards with 2.75" standard remington Foster style slugs. 224 Valkyrie. Inside of 10 yards, where I plan on defending my home, I want that inch-per-yard cylinder spread. Most people think that the trajectory of the 12 gauge rifled slug is close to that of a mortar, and since they don't think they could hit anything past 25 or 50 yards (which is probably true if they don't have a set of sights on their shotgun) they zero for slugs at 25 yards. While still inferior to the 12 gauge loads, the Buckhammer and Brenneke slug loads (which claim similar ballistics) at least get the 20 gauge slug gun up off of its knees. This gives the Foster slug stability and allows for accurate shooting out to ranges of about 50-70 yd. Most people think that the trajectory of the 12 gauge rifled slug is close to that of a mortar, and since they don't think they could hit anything past 25 or 50 yards (which is probably true if they don't have a set of sights on their shotgun) they zero for slugs at 25 yards. Not sure how precise it is though. However, they really stood out in terms of trajectory. Typical trajectory of a Foster that is sighted-in to hit 2" high @ 50 yds., it will put you at zero @ 100 yds. from point of leaving barrel a bullet or slug is on the rise or arc at 50 yds 1 1/2 to 2 high dead on at 100 yds and should start to drop from there depending on your barrel at 125 yds mine is around 3 to 4 inches low and goes down from there there are some good web sites to do some research on bullet trajectory alot of people have huge misconsceptions on this stuff jersey hunter is 100% correct A couple of inches high at 50 yards would likely serve well. The 100 yard figures are 995 fps and 1074 ft. lbs. The midrange trajectory is the bullet's height above the base line halfway between the muzzle and the point of impact (here, the target). I would like ballistics out to 200 yards if anyone has them. Theres a turret tuned to a 12 gauge slug but it also matches the trajectory of a 350-grain muzzleloader projectile, and another that matches 300-grain bullet dynamics when pushed by three blackpowder pellets. I'm using 260 grain Remington Accutips (2 3/4 inch) and am curious how high or low it will be at 50, 100, 150, 200, etc yards actually you wanted a 25 yard target, not a 20. That may change, though, based on future ammunition and rifle advancements. I'm looking for some ballistics for Remington Accutip Slugs , 20 gauge , 2 3/4, 260 grain. For a slug that has ample energy, maximum practical It is Shotgun Slug Accuracy Tips from the American Slug Shooting Association. I'd atleast use that 25 yard range you mentioned. The trajectory immediately begins to drop below the bore axis. For example, a 12-gauge barrel was designed around the fact that one pound of lead could be divided into twelve 0.727-inch lead balls. I was just wanting to know what the drop on a 1 oz 12 gauge slug would be at about 45 yards. If you plan on shooting past 50 yards and out towards 100 yards I would recommend the 10-yard zero, then memorize the dope or make a range card, and practice at various distances to learn where the rifle will shoot.
