Airgun lubrication — spring guns: Part 1

by Tom Gaylord, a.k.a. B.B. Pelletier

Today, I’m starting a long series on lubricating airguns. Blog reader Joe asked for this; but as I was researching the subject, I stumbled across another request that came in through the customer reviews on the Pyramyd Air website:

“I wish that RWS or Pyramydair would explain the process and frequency of oiling these RWS rifles in particular the RWS mod 48. Everyone I talk with says the RWS owners manual is outdated and that with the new seals they use does not need to be lubed maybe for years….I purchase the RWS chamber and cylinder oil at a cost of almost $30.00 and now am told I probably will never need it? This topic should be cleared up once and for all by the manufacturer.”

What is a top hat? Exploring the guts of a spring gun

by Tom Gaylord, a.k.a. B.B. Pelletier

Last week, I made reference to a heavy top hat affecting performance in a spring gun, and blog reader Joe asked this question:

“You wrote ‘…weighted top hat inside the piston, or the piston itself is heavy. Either way, the rifle should shoot medium and heavyweight pellets better than lightweight pellets.’

What is a ‘top hat’? Why would a heavy piston or top hat shoot medium to heavy pellets better?”

Joe, thank you for asking this question. This blog is now in its 10th year, and I forget that the readership has changed over that time. If one person asks a question, it means that many other readers are wondering the same thing and not writing in. Today, I’d like to review the main parts of a spring-piston airgun powerplant and discuss how they affect performance.

What’s for Christmas? Part 2

by Tom Gaylord, a.k.a. B.B. Pelletier

Part 1

This topic was received well last week, so I’m doing the second list today. Several readers have reminded me of other gifts I should mention, and some of them will make today’s list. If I don’t list something you suggested, there’s a reason. These are the things I recommend without question.

Stocking stuffers/small, neat gifts

Gifts in this category don’t cost a lot but will have great meaning to airgunners. Some of them are things that shooters won’t buy for themselves.

Air Venturi Pellet Pen and Seater
Someone suggested the Air Venturi Pellet Pen and Seater, and I have to agree. This is a great gift, and it’s one that a lot of shooters won’t buy for themselves.

What’s for Christmas? Part 1

by Tom Gaylord, a.k.a. B.B. Pelletier

I know the Christmas holiday is a long way off, but this year it comes upon us faster than usual. Thanksgiving will be very late this year (November 28), and since that day traditionally kicks off the Christmas shopping season, many people will be jammed because of too little time left. So, I’m starting my Christmas shopping blog a couple weeks early.

Stocking stuffers/small, neat gifts

Things in this category are gifts that don’t cost a lot but will have great meaning to airgunners. Some of them are things that shooters won’t buy for themselves.

Leapers UTG pellet & BB trapLeapers UTG pellet & BB trap
The Leapers UTG pellet & BB trap is the best trap for BBs, and it also works for lower-velocity pellet guns. I used to tout Crosman’s model 850 pellet/BB trap. Well, they removed it from the market and replaced it with a model 852 trap that they say is only good for pellets. There doesn’t seem to be much difference between the Leapers and Crosman traps, except the Leapers trap is a few dollars more. How’s that for a switch?

Why powerful mainsprings don’t always increase velocity

by Tom Gaylord, a.k.a. B.B. Pelletier

Today’s report is the one I mentioned forgetting in last Friday’s blog! Blog reader Errol reminded me about it yesterday.

I hear this so often from airgunners — how they think they’re going to add a more powerful mainspring to their airguns and increase the power. It sounds logical, but it often doesn’t work; and it nearly always doesn’t work as well as you think it should. Today, I want to discuss why that is.

Fact 1
The Weihrauch HW 35 was always considered to be one of the most powerful airguns in its day — which was the 1950s. They delivered over 700 f.p.s. when new in the 1950s; and over time, this rose to 750 f.p.s. Careful tuning could get close to 800 f.p.s. from certain guns. This model is still being made today, but now it sells because it’s so pleasant to shoot and doesn’t produce excessive power. How times change!

We’re certainly getting a good look at the Benjamin Trail NP pistol! While the title says this is Part 6, it’s actually the 7th report because Part 4 was so large it had to be broken into two parts.

Let’s look at the performance of the pistol after break-in. This test pistol has been shot so much that it’s now broken in, so today we’ll look at the velocity. Crosman says in the owner’s manual that the pistol needs several hundred shots before it’s fully broken-in, and this gun certainly has that many shots through it.

Before we begin today’s report, a word about my late friend, Earl (Mac) McDonald. His family has set up a memorial page in his name to collect finds for research into the causes of Creutzfeldt-Jakob disease, which is one of the names prion disease goes by. Most of you knew Mac only through his writing and testing here on the blog; but a few of you were friends with him through this hobby, and I thought you would like to know about this.

Today, we’ll continue testing the Benjamin Trail NP pistol. Although today’s title says Part 5, it’s actually the 6th report because I had to break Part 4 into sub-parts a and b.
