    Any idea on what this is?

    A friend picked this up used, from a used dealer who took it in in trade. It has a nice fully adjustable trigger that suggests a match style rifle. It appears to be CO2 operated and has a "fill tube" but it is not clear what it uses for the fill. It is .177. It has an Anschutz style to it...

    N/A Benjamin 10.5 gr Match Grade

    I was able to try the Benjamin 10.5 match grade .177 pellets in my TX200 MKIII today. It is a limited test given the weather. I was shooting 50-feet indoors. Using A-17 targets I shot 3 cards. I shot straight from the tin. The scores were 98, 98 and 99. This is comparable to scores from weight...

    Air Arms Revist pellet performance in my TX200 MK III

    After a year of shooting Air Arms Field Heavy (10.3 grain) and Air Arms Field (8.4 grain) pellets I decided to revisit pellet performance from other makers. Note every rifle handles shooting pellets differently so your results may differ. I am shooting a TX200 MIII in .177 with a Vortex...

    Air Arms TX200 50-Yards Trigger Control Part II

    I have not pestered folks here for a bit with a video. It has been busy at work, and I have been shooting indoors. Here I move back outdoors and find I need to continue to develop my skill. This video follows a similar format and process as previous videos. I am shooting a TX200 MKIII .177...

    Tuning Effect of loose Forend Screw on Consistency of TX200 MKIII

    I was recording my shooting for review, as I usually do, and had an interesting thing occur. I thought it might be of interest or help to others. This is a video that was not planned. I was shooting my TX200 MKIII at the indoor range and discovered its’ performance was declining. An...

    Tuning TX200 MKIII 50 Yards - Importance of Trigger Pull

    In this video I examine the effect of my being more conscientious in my trigger pull. While the “warm-up” target was shot carefully, attention to a precise trigger control was not as stringent as it was with the second target. Often, for me, the difference with my shot performance is the...

    Tuning Pellet prep

    I have been ill for a few days. As a means to kill some time I did a pellet prep bing yesterday. I prepared about 3000 pellets for the final lubrication phase for use in my TX200. I don't do that phase until I am ready to shoot them. I typically use AA Field Heavy 10.3 grain in 4.52mm as...

    Tuning 5 and 10 shot groups: Does it matter? (TX200 in .177)

    There has been discussion recently regarding the utility of 5-shot groups to understand consistency of ammo and rigs. Some claim it is of no utility, while others feel it is functional. This video is an initial comparison of the utility of 5-shot and 10-shot group processes. This video begins...

    N/A Effect of sorting with TX200

    I have been using AA Field Heavy 10.3 grain in 4.52mm for about 9 months now. They have generally functioned well for me. But, they seem to do better sorted by weight. I typically buy 4 tins of 500 at a time. I sort to 1/10th of a grain. However, the last batch or two I received have been...

    Air Arms Comparing 5-shot &10-shot groups at 50-yards. TX200

    There was a discussion recently about the impact of various shot strings sizes for groups when testing projectiles etc. I thought I would do some testing of this myself as I have largly moved to 10-shot strings these days. Now, I have no issue with 5-shot groups, mind you, but to me they do not...

    Q for TX200 MKIII owners...

    So I rebuilt much of my TX200 MKIII after about 15,000 to 20,000 rounds. It has been doing great. New spring, compression tube, seals, bearings etc. However I couldn't get a cocking shoe. As it is a major pressure point it seemed like it could wear. Anyway, today I was shooting at...

    Finally Finished Video: TX200 at ~25 Yards in the Wind

    It took a bit of editing time as I had camera trouble but I finally finished. I do know if it is of interest to anyone or not. I have been revisiting my understanding of the effect of wind on my shooting the TX200. I had spent some time to check out the impact of wind on my .177 spring air...

    Q: Who rebuilds compression tubes?

    A member was kind enough to to send me an unneeded compression tube as AA was out of stock. The one that came out of my TX200 I think needs attention. Is there someone who can work on them? I do not know if it is just an o-ring or there is another issue. I would like a spare.

    Back at it TX200 at 50-yards

    I spent a couple days shooting at 25-yards and while ok, I was disappointed in my shooting. I was pulling 211 to 215 scores on USBR targets and not where I expected to be. I will get back to those. Today the range was very busy. I spent a lot of time socializing and less time shooting...

    Just for fun: Shooting Steel at 50-Yards with a TX

    I was at the range earlier today for a fun day. I was not testing anything or trying to do anything different. I was there just to shoot for fun. I had my TX200 MKIII and was shooting AA 8.4 grain pellets at steel action targets set up at 50-yards. I shot a squirrel and rat target. I shot 1”...

    AA Field 8.4 grain at 50 Yards (TX200 MKIII)

    In a previous video I looked at the performance of other pellets such as AA 10.3 Field Heavy at 50-yards. This video checks out the AA Field Diablo 8.4 grain pellets at 50-yards. These are 4.52mm head sorted to 8.4 grains. There was some wind at times. There was also a biting fly attack which...

    TX200 MKIII at 50-Yards with AA 8.4 Diabolo

    I posted some work with the AA 10.3's previously. I don't shoot 8.4 grain as often but they do pretty well. Here is a video using my TX200 MKIII in .177 (FAC) after being rebuilt with standard AA FAC parts. There is an addition of a 3MM washer in front of the top hat. This washer is supposed...
