Quackenbush .308 big bore is an attractive airgun.

The last time we looked at this Quackenbush .308 big bore was when I discovered that my rifle really likes Mr. Hollowpoint’s 68-grain hollowpoint bullet. I also tested a 150-grain Loverin-design bullet that was just a bit too heavy for the gun. It didn’t want to stabilize and was tearing elongated holes in the target at 50 yards.

If you’ll recall, I was running low on air that day, so I could fill the rifle to only 3,000 psi. That gave a stunning group that was smaller than one inch at 50 yards with the 68-grain hollowpoint, but I wondered whether it would do any better if I filled the rifle to higher pressure. I also wondered if going just a trifle faster would have stabilized the 150-grain bullet. There were a lot of unanswered questions after the last test. read more

It’s been a long time since Part 2 because I was searching for a better bullet for this rifle. Oh, the groups shown in Part 2 aren’t that bad; but when you see what I have to show today, you’ll be glad I stuck with it. read more

Announcement: The blog’s server went down on Thursday, April 21, 2011. It came back online Sunday, April 24. This blog was published early Monday, April 25, and is dated Friday, April 22. Monday’s regular blog will be published in the afternoon of Monday, April 25.

This is a good, long report, so grab your coffee and perhaps another Danish. Today, we’ll learn something about accuracy and group sizes.

I’m testing the accuracy of the .22 caliber BSA Scorpion PCP air rifle, and it’s quite nice! Helping quite a bit was the weather at the range, which was perfect for long-range airgunning, as there wasn’t a breath of wind to be felt. The day was overcast and misting slightly and with every shot you could see vapor at the muzzle when the compressed air emerged. read more

Part 1


This is the new Crosman Silhouette PCP pistol. It’ll send those light little airgun silhouettes into orbit.

Today is velocity day for the Crosman Silhouette PCP pistol, and there’s much to report. For starter…what a little sweetie this pistol is! This is one of those every-so-often-they-make-a great-one guns. The trigger seems to make all the difference in the world, but the power it generates is an additional benefit.

But I’m getting ahead of myself. First, I filled the gun to 3,000 psi, as indicated by the gauge on my carbon fiber tank. The onboard manometer read about 100 psi less. But no matter, as I only watch one gauge during the fill, and the larger one on the tank is very reliable. read more
