This report is taking on a life of its own! I am going very slowly and thoroughly through the testing of this Benjamin 310 BB gun to record everything for posterity. In Part 3 I started the velocity test and today I intend completing the steel BB portion of it.

Does it hold air?

My last report is dated Friday, September 2, 2018. That means I tested the airgun on Thursday, September 20. While you are reading this report on Monday, October 8, 2018, I actually wrote it on Friday, October 5. That means the tests you are about to read were also performed on that day. First I wanted to see whether the gun is still holding the two pumps of air I pumped into it at the completion of the last test on September 20. A total of 14 days and several hours have passed and I have not touched the gun since the last time. Is it still holding air? read more

A history of airguns

Sharpshooter pistol
The Sharpshooter catapult pistol was made from the early 1930s until the 1980s by as many as 5 different companies. This one was made in the early 1940s.

This report covers:

  • Why not oil?
  • First test
  • Moly-powder
  • Test 2
  • Test 3
  • Changing direction
  • Test 4
  • Conclusions
  • Summary

I said we would get deeper into the velocity of the Sharpshooter pistol this time, so that’s what will happen today. First I need to tell you that one of the two rubber bands I used for the velocity test last time broke, so I have to install another one today. Before I do that, though, I want to test my other velocity idea, which reader Paul in Liberty County correctly guessed was applying a dry lubricant to the gun. He thought it might be graphite, but I actually want to try powdered Molybdenum Disulfide. read more

Before we begin, I want to share an email I received last Friday. It says a lot about the experience of attending the Pyramyd Air Cup.

“Hi Tom, 

Meeting you in person for me was one of the highlights of the Pyramid Air Cup 2018. I’m the tall guy shooting any tournament for the first time. I shot a TX200 and had questions about a second air rifle that weekend. We spoke about the Sig P938 and you recommended a Sig 365 you were testing. I wanted to give you my perspective of what I got out my first shoot and ask you to consider sharing my thoughts. Not the shoot but as a newcomer into competition. read more

I’m at the Pyramyd Air Cup today. Veteran readers please help the new guys with their questions while I’m gone, because I won’t have much chance to answer email. I will be back in the office on Monday.

Today we begin looking at the velocity of the Benjamin 310 BB gun. There have been so many comments and requests for me to test different things with this gun that I won’t get through the whole velocity portion today. But I will get a start.

Hollow bolt

I mentioned the hollow bolt nose that differentiates the 310 from other Benjamin air rifles, but I don’t think all of you understood what I was talking about. I remember the first time I encountered this as a kid, it fooled me, too. read more

This report covers:

  • Finish
  • Model 310
  • A sweetie
  • Take our time

Two months ago I attended a small local gun show where the joke is — if you are looking for Indian jewelry, coffee mugs and dream catchers, this is the gun show to attend! Guns? Not so much. But it’s local, so I went. I haven’t had much luck at this show — ever! But because it’s mentioned the intro to this report, you know this time will be different.

I was halfway through the show, looking carefully at everything on each table when my buddy Otho called to me. He was on point the next aisle over. Oh great, I thought. Another rusty Daisy Red Ryder from 1986! But I was wrong. read more


Hatsan 135 QE Vortex .30-caliber pellet rifle: Part 2

Part 1

Hatsan 135 30 caliber rifle
Hatsan’s .30 caliber 135 QE Vortex is a large breakbarrel — both in size and caliber.

This report covers:

  • Adjusting the trigger
  • JSB Exact 50.15 grains
  • Predator Polymag
  • Air Venturi .30 caliber balls
  • JSB Exact 44.75 grains
  • Cocking effort
  • Recoil
  • Discussion
  • Summary

Time for me to bend the bow of Ulysses, which no man but he could string. Today is velocity day, plus I said I would take a closer look at adjusting the Quattro trigger. I’ll do the trigger first.

Adjusting the trigger

All of the trigger adjustments work and I adjusted them all. The trigger came out of the box breaking at 6 lbs. 10.5 oz. and I was able to get it down to 5 lbs. 4 oz. When I did the first stage went away, so I added some and now it feels right to me. I also lightened the first stage pull (1 lb. 10 oz.) by a couple ounces (1 lb. 4 oz.), though it doesn’t seem any different when I pull it. read more

This report covers:

  • Wrong ammunition
  • Two big clues
  • Filling the BB gun
  • The test
  • Sight-in with Daisy BBs
  • Pressure too high
  • Hornady Black Diamonds
  • Getting used to the gun
  • Daisy Match Grade shot
  • Bottom line

Today we learn how accurate the Benjamin 700 multi-pump repeating BB gun is. And we will learn a lot more than that. Let’s go!

Wrong ammunition

Some of you know how I harp on calling a BB gun a BB caliber and NOT .177/4.5mm. Because it’s not! A steel BBs is 0.171- to 0.1735-inches in diameter. It may not matter to people buying one BB gun at a discount store, but to someone like me who has to shoot oddball new and old airguns from all over the world, it makes a big difference.

The Benjamin promotional pamphlet from the 1930s says these guns (the model 600, 700 and 300) use steel Air Rifle Shot of 0.175-inches in diameter. There’s just one problem with that. As far as I can tell, nobody ever made steel Air Rifle Shot in anything but 0.171-0.1735-inches. I wondered if it was possible that the Benjamin writers of that pamphlet were as cavalier back in the 1930s as BB manufacturers are today. Did they really want us to use Air Rifle Shot that is 0.171 to 0.1735-inches in diameter and not LEAD Air Rifle Shot that is 0.175-inches? They did emphasize not using lead balls in these guns. read more
