The 25-Yard results suggested this gun was going to rank among the best...

This review took a lot out of me. You can see it by the end. I filmed over 100 shots through the slow-motion camera.

These have a good review rating at Pyramyd.Don`t get why this gun is set so hot.

Ted,
Your goal of providing visual evidence of what happens to the pellet through its flight at various velocities will be very useful info(yrrah had some video clips of unstable peelets too).
Field Target competitors recommend 870 to 890 FPS for a good compromise between accuracy and flat trajectory. I have a feeling that they are quite right.
Looking forward to your results on this and also your accuracy testing based on pellet size.

You just confirmed in no uncertain terms how complex everything is. Pellet make, caliber, gun, velocity etc, an intricate system that takes a lifetime to master.
I wonder if that same pellet out of another make gun at the same velocity would demonstrate the same instability.

The data is only accurate for this gun and this pellet at this speed.

I will show in the upcoming video that as the speed slows down, pellet stability increases. But, it is not a perfect gradation. You can't simply say that at 8xx feet per second, ALL wobbling STOPS.

I make the effort to convey a sense of "Here is some data - you decide". But, at the same time, offer what I would like to see as the best potential "fix" to a problem. The line between realism and cynicism is a thin one.

One thing is certain - reviews are much easier when everything goes right.

for your videos. My .177 HW 100 was tuned down to 910 fps w/10.3 grain JSB's. While accurate, it was not a tack driver. My Marauder and Air Arms are just a bit more accurate. Some said I was too anal because I returned it. I say "too bad"...at $1400.00, it should be more accurate.

Ted, awesome work as usual.

The piece that I am currently working on is a bit of a enigma in that there are SO many variables to play with. Making it even worse is that I have a total of 11 barrels that fit the action, each taking less than a minute to change out.

While working it through its' paces, I started out just shooting it, without making any adjustments. Just shoot, shoot, shoot, to get a solid base line for performance, and after a short while the group sizes start to become predictable, and somewhat constant.

Somewhere along the line, when I feel like I am getting the best results that it will produce with any given bore/pellet, I start to change things, and see where it will take me. I generally have the reg set to produce velocities in the 800's with 18gr pellets (this is .22) with enough room to be able to make adjustments with spring pre-load only. Generally I find I get the best results at around 880fps with the 18.1's. That being said, I have seen where changing the power, even a little (maybe 5 to 10fps) up or down can show up really fast in the size of the groups that I am popping. Some bores show me that they work better at 875, some at 855, some at 867, some at 895, etc, on the same action, using the same pellets.

I can see some of the pellet flash you refer to, at times during the day, shooting around here. I have been using it for years to help with getting an action where I want it. What I have been learning as of late is that it is one thing to get tight little groups out of a gun, and it is an entirely different story to actually get a pellet to hit precisely where you want it to each and every time. I am only guessing at this time that the difference between tight groups, and a constant precise strike is that pellet "spiral" or "wobble" your video (and Harry's) have demonstrated.

I don't understand... you know it's hot for anything 10.4 and less...Why didn't you test 13.4 gr JSB???

BTW, mine is at 22 FPE with 10.6 gr Kodiak and it is German accuracy at its best all the way to a 100 yard mark.

Ted

If you have an airgunsmith local you can set the rifle you have to run UK spec really very easy.

set the reg pressure to 92 bar

adjust the hammer so the gun spits out those 8.4gr JSB's you have at 777FPS, this is the favoured velocity all the HFT shooters in the UK use.

At about 880 fps and it is a tack driver.
