Benjamin .Bulldog .457: Part Three
This report covers:
- Need higher mounts
- Rubber mulch box trap
- Larger diameter bullet
- Last bullet
- Bullet feeding
Today I sight in the Benjamin .457 Bulldog and shoot a test that a reader asked. It was an interesting test. Let’s start.
I scoped the Bulldog with a Burris Timberline 4-14 AO scope. It’s small and lightweight and seems well-suited to the Bulldog.
Need higher mounts
Though I used medium-height scope mounts, they were too low for comfortable shooting. The straight bullpup stock demands at least one inch more rise of the scope to see through comfortably. I will have to fix that next time.
Rubber mulch box trap
Somebody asked me to shoot the Bulldog at the rubber mulch trap, to assess penetration. I did. I shot the box at one foot distance just to quiet all the questions that would no doubt ensue. I shot it with a 300-grain bullet from Mr. Hollowpoint. The box that was sitting on the grass twisted about 12 inches to the right, but the bullet did not go through.
Yepper — old BB knows you want to see that bullet. So he cut the box open and here is the bullet.
After traversing 12-inches of rubber mulch the 300-grain hollowpoint looks like this. There is still some cardboard embedded in the hollow point of the bullet and I picked out some mulch to take this picture.
So, the much trap does stop things well and the Bulldog is a real thumper. On to sight-in.
I shot the first round at 20 feet, just to see if I was on the cardboard box. The bullet hit in the center of the bull, so I knew it would be okay at 25 yards.
I then moved the box out to 25 yards for today’s test. Yes I will test it at longer distances and yes I will test it with Crosman bullets, but today I’m shooting bullets from Mr. Hollowpoint.
I rested the rifle on the sandbag and started the sight-in. At 25 yards shot number one hit 4.5-inches above the aim point. So I lowered the elevation and fired sight-in shot two. That one hit an inch lower and more to the left. I cranked in a LOT more down and fired shot three. That one dropped about 2.5-inches straight down, so I adjusted the reticle down and to the right and fired a fourth shot.
Then I refilled the rifle and fired again. This first shot hit at the top of the bull, so I used it to start my group. Shot number 2 hit 1.5-inches above the first one that was fired from 20 feet and shot 3 went into the same hole as the first shot.
Remember the discussion about the useful shot count and how a big bore doesn’t really change impact that much when the velocity decreases? I then shot the fourth shot on this fill And it went into the center of the bull, where the shot from 20 feet had hit. That’s a lot of stuff, but I will show you the target so you can see what happened. Use this paragraph to understand the photo below.
This one is hard to measure because I shot the group at the sight-in target, but it’s 4 shots of the .457 hollowpoint that weighs 300 grains in about 2.5 inches at 25 yards. I marked all the shots for you.
Larger diameter bullet
Okay, here is a teaching point. The next bullet I shot was also a 300-grainer, only this one was a flat point and is sized 0.458-inches. Watch what happened. Four bullets (on one fill) went into 0.845-inches at 25 yards. It looks bigger because these bullets are almost a half-inch in diameter.
The last bullet I tested was the 255-grain hollowpoint from Mr. Hollowpoint. This one did well in the Texan and I expected it to do well in the Bulldog. Four shots went into 0.584-inches at 25 yards. Cowabunga! Will I have to get the trime out next?
Guys — this is a big bore rifle. It isn’t for target shooting. I’m only doing this to give you an idea of what to expect.
The bullets did feed better during this test. None of them flipped in the clip when I loaded them and the bolt only flipped one as I cocked the rifle. It fell back on its own when I smacked the stock a couple times with the heel of my hand.
So the Bulldog cannot shoot through 12-inches of rubber mulch. But it does come close.
The clip isn’t as much of a problem as I said in Part 2. It just took getting used to.
The Bulldog is accurate at 25 yards. Lighter bullets seem to do better and 0.458s seem to do better than 0.457s.
The straight stock means the scope has to be mounted much higher.
Four shots are accurate out to 25 yards. I will also try them at 50 yards.
The .457 Benjamin Bulldog is turning out to be a much different big bore than the .357 Bulldog. This is the real deal and seems to be a rifle that can harvest a deer or wild pig with authority.
