Any advice for a guy to get better accuracy. At 20 yards I'm getting like a 2.5" groups with my umarex gauntlet I have a bunch of the mods done from hajimoto. Got plenty of power I just need to reign it in mostly been shooting jsp king heavy 33.95 grain I want to be able to get it down to an inch at that distance at least. I have a Benjamin p rod that is much more accurate. Any help would be great thanks a bunch
Getting better accuracy
- Thread starter Deverdo
- Start date
I had the barrel cleaned lapped and polished and recrowned via haji as far as velocity I have to get a chronograph still

"Lapped" is a generally misused description. If the barrel was actually lapped and not just polished, then I hope whoever did it was knowledgeable. Without a chrono you're kind of stuck. I don't own a .25, so someone with specific experience can better tell you the velocity range in which you need to be working. My guess, the rifle is shooting too hot, but that's poor accuracy, even with an imperfect tune.

Try tuning it down, you could be just pushing the projectiles too fast. Get a chrono first and then adjust your tune. Even with the stock gauntlet you should be getting 1/2 inch group at 25 years at most.

Assuming the barrel is good, it seems like you've got a clipping issue. Projectiles don't actually have to contact anything forward of the muzzle to be deflected. If the projectile is passing too close to a baffle or something in the shroud/moderator after the muzzle, pressure waves created by the projectile can bounce back onto the tail or skirt, disrupting it's flight path. Of course, if it is physically clipping the problem will be a bit worse.
That or maybe the shroud or something on the barrel is loose?
I suppose the tune could be REALLY bad, but hard to imagine it being 2.5" bad at that short distance

@Long_Gun_Dallas: very good point on clipping! I didn’t mention that because he said he has Hajimoto baffles which usually are very good quality but still should rule it out as a cause. Try without any baffles and unscrew the end cap to eliminate clipping first.

You guys have a recommendation on a fairly inexpensive chronograph or should I just pony up the money for a Caldwell

How are you resting the gun? Is your table/bench stable? Are you on bipod? Freehand, standing in the wind with a marble in your shoe, you should be better than your reported groups

Are you resting the barrel on bags or on something? Have you double checked your optic and mounts? Sometimes switching to another optic takes just minutes and it eliminates that variable. Are your holes in paper actual holes or are you sending pellets and slugs into paper sideways sometimes? I would restack the baffles and check the air stripper. I would consider a complete tear down and start over putting it together from scratch and would also consider running a borescope down the barrel. A 5.5mm borescope on amazon is $10 or so and that just plugs into your phone or laptop.
For Air Guns I have found this little guy to work well found this open box one on amazon for $29 https://amzn.to/3CGmqNG I think I paid $39 for mine on EBAY. And its super small and compact and it just works, I put it up against my Caldwell chrono and every shot was within 1 meter of each other which makes sense since this reads in meters per second, and the conversion to FPS is easy. FYI if you don't want to clamp it on your barrel do what I did and just attach it to a tripod to sit that perfect height right in front of the barrel, but its so small you really don't want it out in front of the gun like a traditional chrono. I have used it with 177 22 25 30 and it has worked with all. I really cant complain, I would say the error read rate is something like 1 out of 50 shots. In one of the amazon reviews someone has pics of them using it on a 457 Airforce Texan lol. But $30 to know what your gun is actually doing is priceless.

Oh... I forgot the obvious.... Try a different scope or sight! I've been duped by several bad scopes in my time.

I think this may be the chrony Deadhorse was refering to , it does work well.

The Competition Electronics at around $130, with blue tooth connectivity is a good, inexpensive chrono. I also use a Magnetospeed, which I like a lot, as it needs no light source, and I do a lot of tuning indoors. It's about $350, I think.

I'm not familiar with that rifle, but it may have an easily accessible hammer spring adjustment. If so, until you get your chrono, you might try turning it down a little and see if it improves accuracy. Just remember how much you turn it. If it's like most, and if the rifle is shooting as fast as I think it might be, I'd try a half turn and see what happens. This won't replace a well-balanced, proper tune, but it might suggest the problem, and cure.

That seems to be a rather insulting and unsupported comment. Maybe it's time to chill and have a calming evening libation.

A very stiff trigger many times does not contribute to accuracy.
A bad scope (loose rings or a defective one) will not allow you to shoot accurately.
Are you sure you always hold the rifle the same way?
Making the preassure on the rifle to fall under certain psi will affect accuracy.
Are you able to "feel" a movement at the shot or you stay on the spot at which you aim?
In a simple way you first have to know if you are the problem or if the problem is on the rifle.
If you can shoot much better with other rifle, the the problem is on the rifle.
If you get similar results with all rifles, your technic has to be improved.
If the problem is on the rifle and not in the scope, you might rather buy another rifle with better capabilities. Otherway you can ran out of pellets and the rifle will keep shooting as a shotgun.
