Blog #26 Air Rifle testing of new spring and PCP air rifles in 2019.

Air Rifle Testing at Gunroom.

Testing each air rifle sold has always been our goal here at Gunroom, but with the increase in sales, I have found the transfer of data in hard-copy a time-consuming exercise. What is also evident is that many new air rifle buyers do not follow or take notice of this data.

As most of you are aware, the testing is done using a SIUS 25/50 Target System that provides extremely accurate shot placement and together with our CED Chronograph, they provide a complete ballistic report.

The only caveat here is that as the air rifles are new when tested, their performance will change to some degree once the barrel has ‘leaded up’ and springs together with seals have settled in. That said, when the air gun is handed over, the new owner will be given the best performing pellet for the air rifle as it is in its’ present form.

The new Air Rifle Testing Regime.

Until further notice, new air rifle purchases will receive the following pre-delivery and testing format, regardless of the cost of the air gun. I will test fire each gun using a minimum of 6 pellet types and based on grouping, will select the best performing pellet.

The pellet will be expected to achieve what I consider to be the anticipated speed for the given weight and ballistic coefficient of the selected pellet for the given rifle. A 6-shot group will then be shot and the chronograph results will be recorded and plotted to a Microsoft Excel Spread-sheet File that has the following information:

The Target results from the SIUS will be provided as follows:

H&N Extreme Target

H&N Extreme Pellet Test Target

Note that the image is zoomed to 300% with the actual grouping at the bottom right of the image, in this case, CLD: (Outer Diameter) 8.4mm. These results will be emailed to the buyer and not reproduced in hard copy.

Optional Testing Results.

Now there are going to be a number of you who want more than what I provide above and for that Gunroom offers the following service at a cost of $60:

A full 6 shots of 6 pellet types on a Spread-sheet as below:

The Spreadsheet comes together with the following graphs for those of you who prefer the visualisation of results:

So we are clear here guys, a ‘Pellet Selection Test’ is just that, a “test”. It is NOT a tune-up, though if the air rifle was shooting below its’ rated capacity, then I would retrofit it with a Vortek or Maccari spring and seal at no cost to you.

The idea of a Pellet Selection Test is to short-circuit the time and expense that it would take for you to do the same task. We are well equipped to handle all types of air rifles, from springers to PCPs, with the equipment and experience to do the job. By testing the air rifle prior to delivery, you can immediately start shooting with the results that you would expect for the outlay that you have made.

With most of the calls I get about guns not performing, the customers blame the supplying Gun Dealer, when in fact, the problem is that the gun has not been tested. I do not know of any Gun Dealer who pre-tests the air rifles before they are shipped out and that is the main cause of problems when the customer cannot hit what he is aiming at.

PCP Air Rifles.

I would seriously recommend buyers of Brocock, Daystate, Kral and Weihrauch PCPs who buy from Gunroom, to get the full Pellet Selection test done. Given the higher costs of these PCP air rifles, you need to squeeze out everything you can that will give you accuracy and power: a full pellet selection test is a good start.

For those of you who decide to get the full Pellet Selection test, let me know what you intend to use the PCP air rifle for and that will affect the pellets that I test. I will probably make some minor adjustments that I consider beneficial for the intended use of the air gun.

Air Rifle Testing Summary.

By testing your new air rifle here, I can also adjust your trigger for you if required. All you need do is let me know what pressure you want it to ‘break’ at and I will set it up for you. There is no cost for this.

If you have purchased your air file from another dealer and it is not performing, providing it has originated from Gunroom (i.e. Brocock, Daystate, Kral etc), then I will look at it and fix the issue for free. You will need to pay the freight back and forth.

However, if the air rifle is another brand or one purchased on the ‘grey market’, you are basically on your own. I can look at it, but please call me first and do not just send it to me. I will price the task for you and you can then decide what you want to do.

At the time of writing this, Lewis Reinhold is tasked with looking after most of the springers that come through here while I do the PCP air rifles and machining/polishing work. When sending us an air rifle, please call first and it HAS TO BE LICENSED, OK? Seriously guys, please don’t send me anything that is not licensed. It is not me that has an issue with that, but Weapons Licensing here in Queensland are not the most congenial public servants that I have ever met….

This brings me to the issue of testing springers that have been worked on. Unless you have specified that you want your springer tuned after a repair, it will only get a test fire to check the speed and energy. Changing a spring and seal is just that, a swap out with some polishing and shimming. It does NOT include a tune-up, please realise this, guys. We will always do the best we can to keep pricing down and affordable in an effort to promote the air rifle fraternity in Australia.
