any NON PCP .177 that can produce close to 30fpe?

[Back_Roads]

I have a Hatsan 135 Vortex in .177 that will do very close to that and may exceed with the right ammo IIR.

OK I shot some .177 NSA 12.5 gr. slugs out of the 135, over the crono, just over legal FT energy with 20.25 foot pounds of muzzle energy at 854 FPS avg.
  Bet them 50 yard shots in the wind will be easier They do fit the bore nice and snug, but can push in with thumb with out extreme effort.

 Some of the old xl1500s were making around 27 to 28 fpe. David

Might work with a tuned spring gun and heavy pellets. I had the loan for review several years ago of a Mac1 “steroid” conversion Benjamin pump gun that would spit out 14gr Crosman .22 pellets at close to 30 ft-lb. I think it took around 20 pumps. The Theoben Eliminator (aka the Beeman “Crow Magnum”) in .25 generated a a similar amount of energy.

I just noticed this old thread on high-power non-PCP .177 cal airguns and wanted to add some recent chrony results from a new .177 caliber Hatsan 135 Vortex gas piston QE break barrel. I had a Hatsan 135 in .30 cal and also one in .22 cal and was curious to see how the .177 would make use of the large volume of available compressed air.

The attached snapshot shows chrony results for 8 types of pellets and 2 types of slugs out of a new Hatsan 135. Power was not as high as I'd expected given the performance of the larger calibers, with the 3 most powerful .177 pellets only producing between 20.6fpe and 20.9 fpe. Just checked some old chrony results with a Gamo Mach 1 in .177 and the top power pellets there averaged between 14fpe and 15.5fpe.

I'd purchased Hatsan 135s in all 4 calibers in order to finish a year's long project testing the power increases resulting from the use of ~6ul of raw linseed oil as a pellet dieseling agent. The chrony & power results of dieseling a dozen types of pellets through a dozen different models of break barrel rifles with raw linseed are already posted elsewhere on the forum.

The .177 cal 13.43 grain Exact Monster pellets were the only .177 pellets I tested which exceeded 30fpe when dieseled with raw linseed oil, which for technical reasons is the only safe and consistently predictable dieseling agent I've found. That's a power increase of approximately 75% over baseline power for that pellet in the Hatsan 135. Dieseled pellet power increases with linseed oil usually average between 35% and 65% power increase over baseline, across all calibers, with the Hatsan 135 in .30 cal consistently producing 50+fpe when dieseled.

any big bore filled with co2 will make 30fpe

Can you hit anything with a 30 fpe .177 break barrel?

Can you hit anything with a 30 fpe .177 break barrel?

Yes and hard...if you have enough room to get a good swing with it!

Anyone know of any non pcp air rifles that can produce close to 30 fpe in .177?

Don't know about .177 cal but years ago I shot a .25 cal Beeman Kodiac (rebadged Webley Patriot) that was brought to a DIFTA field target match (LOL, not for field target shooting). That Kodiac was shooting .25 Cal 20.06 Grain H&N Field Target Trophy Domes @ 800fps mv for about 28 1/2fpe.

The owner of the gun told me that he used it to dispatch "trash can raiding raccoons" and it was rather accurate when I shot some targets with it. IMHO, 800-880fps is the "sweet spot" for accurate pellet flight so I have no idea why anyone would want to shoot a .177 cal pellet of any weight at 30fpe. That would mean that the gun would have to shoot a JSB Exact Beast Diabolo .177 Cal 16.20 Grain Domed pellet at about 913fps!!!! LOL, if that were possible I see burned piston seals, lead fouled bores along, possibly with unstable pellet flight, but it does seem that a .177 cal 16.20 grain pellet would have really good BC & SD :C.

There are .177 slugs and heavier 13g+ pellets now... so if you could get accuracy..


Me I would just put a long barrel on my nice light .177 Stormrider... Might be able to get close with a custom multi pump air rifle with a big valve and long barrel...

771 fps out of a Hatsan 135 .177 with NSA 20.5gr. If the calculator is right, it's right on 27ft/lbs.

Anyone know of any non pcp air rifles that can produce close to 30 fpe in .177?

A low cost alternative for your needs – and all in all not too bad looking either- is the Artemis GR1600W . According to factory specs : 29,5 fpe

https://www.fusil-calais.com/en/2447-artemis-gr1600w-air-rifle-177-bore-40-joule.html




Factory page :

The .177 cal Artemises don't shoot anywhere near the manufacturer's claim of 40J (29.4 fpe). More like 30J (22 fpe)

Wanted a GR1600W bad. Could never find one. It's like "Shoot the Thrill" shooting my old 135, 155 and Beeman Mach 12.5 but after shooting them you have to wait till your eyes refocus to see if you hit anything. Wonder if Krale in Holland could get one.

Like I said above, the Artemis GR1600 .177 cal shoots 40J only in manufacturer's claims / dreams. User-measured ME's are closer to 30J.

Magtech AR N2 Extreme .177 cal claims (by manufacturer) to be the fastest spring-powered airgun: 1600 fps. 5.4 gr. alloy pellets have reached around 1480 fps, in reality. That's 35.8 J / 26.3 fpe. I don't think you are going to see a non-PCP .177 cal in production that would beat that. (midweight pellets don't have as much kinetic energy in the N2).

[Bayman]

I don't see 30 fpe attainable with a piston rifle. The gun is limited by swept volume and very short pressure peaks. Also pellet velocities would be supersonic or near supersonic and accuracy would be terrible. Perhaps heavier slugs would bring speeds down to more accurate levels. Typically piston guns don't shoot slugs well. Not to mention a piston gun's power generally decrease as pellet weight increases.

Forgive me I didn't read through the whole thread but I don't see why anyone would want a 30 fpe 177 unless it's a caliber restriction. I believe the only way you can get that kind of power with accuracy is going to be with a PCP shooting well designed and probably heavy slugs.

20 fpe piston guns are twice as difficult to shoot accurately as 12 fpe guns. I can't imagine how hard it would be to shoot a 30 fpe piston gun. Strongest piston gun I ever shot semi accurately was my Rx1 at 24 fpe. That was in 20 caliber which is more efficient and smoother than 177.
Best of luck with your search.
