I can't shoot lead at coyotes anymore, when I did shoot lead I liked the copper coated lead BB's over number 4 buck shot because there are over twice as many pellets in the lead BB load. The 3" lead BB's and the 3" lead number 4 buckshot both do a great job of killing coyotes at 40 yards or less, but they are not as good as 3" Hevi-Shot Dead Coyote or 3" Remington Wingmaster HD BB or T shot loads. The heavier than lead pellets that are hard and stay round, they pattern great and out penetrate the lead pellets by quite a bit. If I could still shoot 3" Federal Premium 1-7/8 oz of copper coated lead BB's I would because they work good and don't cost a arm and a leg. All of the heavier than lead loads that I patterned and shot into catalogs to check for penetration out performed my old favorite Federal Premium lead loads by a bunch. Here is some info I posted on PM a while back.I went out today and shot at some paper and shot some catalogs to check out some penetration on the different types and sizes of pellets. Here are a few of the pattern pictures.
The first picture is a pattern from 40 yards with a Carlson's Dead Coyote choke using a Federal Premium 2-3/4" number 4 buck load. This load has 34 pellets in it. The only reason I shot the number 4 buckshot load was to check the penetration out. It put 9 total pellets in the 12" circle, one of those was in the center 3.5" circle.
This picture is a Hevi-Shot 3" Goose load with "B" shot in it. This load had 73 pellets in it, 56 of those pellets hit the 18" X 22" paper. The 12" circle had 25 pellets in it, 5 of those pellets were in the 3.5" circle.
This picture is of a Remington Wingmaster HD 3" #2 waterfowl load. This load had 124 pellets in it, 108 of those pellets hit the paper. The 12" circle had 55 pellets in it, with 10 of those pellets being in the 3.5" circle.
Here is a picture of the catalogs I shot into on the penetration test at 40 yards. On the first catalog I shot into, I shot it with a Hevi-Shot "B" load, a Rem HD #2 waterfowl load and a Federal Premium lead copper coated BB load. The first pellet I found at "80 pages" was one of those ugly Hevi-Shot B pellets with two smaller size pellets that were stuck to it. At "page 115" I found 1 Rem HD #2 pellet. I only found two of the lead copper coated BB pellets in the catalog at "pages 211 & 279". The Hevi-Shot B load I found a total of 9 pellets, 7 of those were between page 80 and page 279 and the other 2 B pellets were found at page 359. Of the 25 Rem HD #2 pellets I dug out of the catalog, most of them were between pages 211 and 319. 4 of the #2 HD pellets were between pages 359 and 429. The next catalog I shot was kind of a shocker to me. I shot it with number 4 buckshot, Dead Coyote 3" T shot and Rem HD 3" BB water fowl load. The 4 copper coated lead number 4 buckshot pellets came out of pages 316 to 337. They were all mangled up. I found 7 Dead Coyote T pellets, 1 at page 218, 1 at page 291 and 1 at page 316. There were 3 T Dead Coyote pellets at page 367 and 1 at page 420. Here is the shocker part. I found a total of 10 Rem HD waterfowl BB pellets in the catalog. The first one was at page 290, 3 pellets at page 413, 1 pellet at 465, 2 pellets at 507, 1 pellet at 581 and the deepest pellet was at page 610.
This is a picture of the pellets I removed from the catalogs. The top row is the messed up copper coated lead #4 buckshot. The second row is the Dead-Coyote Hevi-Shot T pellets. The 3rd row is Rem HD BB and on the right are the copper coated lead BB's. The 4th row is the Rem HD #2 waterfowl pellets. The 5th or bottom row is the Hevi-Shot B goose load pellets. So what I got out of this was my old favorite Federal Premium lead copper coated BB's are not near as good as the Rem HD 2's or BB's. I was pretty sure the Dead Coyote T shot would out penetrate the 4 buckshot. The Rem HD BB's out penetrating the number 4 buckshot and the Dead Coyote T loads was a surprise. The Rem HD #2's look to be much better than the Hevi-Shot B goose loads also. The HD 2's out penetrated the Hevi-Shot B pellets and there was 51 more HD number 2's per shell than the Hevi-Shot B load.
This pattern is from a Federal 3" Premium 1-7/8 oz copper coated BB load that had 98 pellets in it. 15 pellets hit inside the 12" circle.
This picture is a pattern from a Remington Wingmaster HD BB waterfowl load with 1-1/2 oz of shot. This load has 73 pellets in it or 25 pellets less than the Federal Premium BB load. This HD load of BB's with 25 less pellets in it put 32 pellets in the 12" circle. So the heavier than lead load with less pellets in it put over twice as many pellets in the 12" circle at 40 yards than the copper coated lead load did at 40 yards.
