My sermon today is in the form of a repentant sinner, because Ive made most of the mistakes Im telling you to avoid. The difference between a trap and a backstop. A bullet trap is designed to stop whatever is shot into it. Targets are hung in front of the trap, and its expected to stop all bulletspelletsBBs that enter. A backstop is often set behind the trap to stop the bullets that miss the trap. If theres a trap, the backstop is only called upon occasionally but sometimes theres no trap just the backstop, in which case the backstop, alone, has to stop everything. Starting with BB guns. When I was a boy, the most popular trap for BB guns was a trash can or wastepaper basket filled with crushed newspapers. The Sims 2 Apartment Life Torrent Download Crack Internet more. It worked, but not for very long, so lets talk about that. Crushed newspapers are great padding for packages. The newspapers have enough resiliency to keep the contents of the package firmly in place unless those contents are very heavy. And the same crushed newspapers will stop BBs from low powered BB guns like Red Ryders for a short time. But and this is important even a Red Ryder will eventually shoot through the crushed newspapers when one BB after another impacts in the same spot. And, if the BB gun is more powerful, it doesnt take as long to tear through. Red Ryders shoot at around 3. But some powerful BB guns like the Remington Air. Master 7. 7 top 7. Theyll rip through crushed newspapers in one tenth the time it takes a Red Ryder to get through. When youre making a BB trap, consider both the length of time youll be shooting at the trap as well as the potential velocity of the gun doing the shooting. A better way to stop BBs is to provide a backstop that has some give like a piece of wall to wall carpet. When the backstop moves, it robs the projectile of a lot of velocity, which prevents bounceback the bane of the BB gun. And wall to wall carpet has a very tough base that seems impervious to steel BBs at Red Ryder velocities. I know of clubs that have made BB gun ranges with large sections of wall to wall carpet that not only stop the BBs but which hang to the floor and are folded into a trough at the bottom to funnel all the BBs into a container, simplifying cleanup. A backstop like that and a large powerful magnet makes cleanup an easy chore. Of course, you can buy a commercial BB trap that will do all Ive described. Crosmans model 8. BB guns and works for low velocity pellets, as well. The only problem is that Crosman has them made in China, and sometimes theyre out of stock for a very long time. The UTG pellet BB trap is very similar and will do the same things. It costs a few dollars more, but the supply is more regular. Both of these traps have ballistic curtains that absorb the energy of BBs at low velocity. A thin steel backplate ultimately stops the projectile. Of course, youll want to put a larger backstop behind this trap for those few projectiles that miss the trap altogether. This Crosman 8. 50 BB trap has stopped thousands of BBs and pellets. Notice how the ballistic curtains have been torn up from all the shots. For the more powerful BB guns those with muzzle velocities over 4. I dont like carpet. Like crushed newspaper, its possible to shoot through it if you keep hitting in the same spot. For those guns, I prefer an actual trap filled with duct seal and use the carpet as a backstop behind the trap. The few BBs that hit the carpet wont hit in the same place, and it should work fine. If the range is to be more permanent, however, put some plywood behind the carpet and keep an eye on the carpet and replace it as needed. On to pellets. Pellets are made of lead, mostly, though theres a movement to use other metals that are less toxic. Lead absorbs energy when it deforms against a hard target. Up to 6. 00 f. p. At velocities above 6. Rohloff Hub Manual more. First, it breaks off in large chunks traveling at low velocity. As the impact velocity continues to rise, the lead fragments get smaller and travel faster. Above 7. 00 f. p. This pellet was flattened at 6. You can still see the pellets skirt, including the rifling thats engraved into both it and the head that is flattened. This pellet was moving faster than 6. Its a smaller caliber than the first pellet, but the breakup happens in the same way regardless of size. You dont want to use a lightweight pellet trap for pellets that move at higher velocities Theyll even punch through steel plates if theyre thin enough. For pellet guns, some thought must be given to what kind of trap you use. I use three traps in my work. One is the BB trap already mentioned. Regular readers of this blog know that I shoot several hundred rounds each week. Often one test involves from 1. So, my traps Im not talking about backstops yet have to be up to the task. Heavy Duty Bullet trap. For all my most powerful airguns, I use a Heavy Duty bullet trap designed to stop a. I bought mine about 2. I thought 4. 5 was a lot to pay. Today, youll pay over 7. My trap has seen hundreds of thousands of pellets and bullets over the years and except for the paint, its still as good as new today. My workhorse heavy duty pellet trap hides behind the cardboard facer. The white backer board behind is half an inch thick and will stop pellets with up to 5. This is the trap I use when I shoot 2. Ive missed this trap a couple dozen times, so I learned long ago to back it with something strong. I use a board of white synthetic material that Edith gave me years ago. Its supposed to be a special board she bought over 1. Since I started using this backer board with the steel trap, nothing has slipped past. The final trap I use is the one that blog reader Jim Contos gave me. I wrote a special blog describing how to build one for yourself. Jim gave me this trap after I reported shooting through my homemade silent pellet trap that Id used for many years. After cleaning the trap and replacing all the duct seal, I was testing a Beeman HW1. S FSB, which is a 2. PCP rifle. Within just a few shots I shot clean through the duct seal and the steel plate behind itIve used this trap for a very long time and with some powerful airguns. What was different this time was the lack of a wadded mass of lead pellets to help slow the pellets that were shot. So they sailed right through the trap This is what happens when a 2. Theres a thin steel plate between that plywood back and the duct seal, and the pellets zipped through it I dont back this trap with anything. I use it only for chronograph testing, where the muzzle is a foot from the trap. I havent come close to missing the trap in over 2. How large should the backer be Make the backer large enough to positively stop all rounds that are shot in the direction of the target. If youre the only shooter, maybe the backer can be smaller but if your range will ever host other shooters of varying abilities, make it bigger. When we lived in Maryland, I often let others shoot on my basement range. I used a 34 inch plywood backer that was 4 feet square. Even then it was just enough to stop all the wild shots. Not everyone waits to sight the gun before their finger moves to the trigger Lets review. So, you always want to stop your projectile positively.
