Hoping for some insight as to how these perform for YA! Zero-ing in on a light weight round to keep up Z velocity in a FX Compact 500 mm barrel. .25 cal to be used out to 100 yards and most shot much closer in 35 to 75 yards......... Wishing to push these @ approx 980 fps to obtain flatter Traj. and better expansion. & finally, In ref. to expansion is the Lead soft enough on the Hybrid's to expand prior to a potential pass through?

Your insight is highly appreciated!
 
The hybrids like the speed, high speed. They also work best using a particular barrel twist rate. I only know the results of Chucks testings with them on the 30 cal hybrids. Him and I talked extensively on this, and for the speed he was after, the twist rate was key. You can do a search on CHUCK treads. It was recent.

on my impact 25 cal, thst currently pushes the 34 grain jsb MK2 Heavy’s at 1007 on power setting number 3, the hybrids did not do well. I have the speed, but probably not the correct twist rate for the hybrids. I personally never cared for these hybrids in 25 cal.

on my 30 Hatsan Hercules bully the 30 hybrids did well. 


But I’ve seen a few folks that swear by them out if their 25 cal fx guns. This is where I have to agree with Elis. You have to go buy some and see how they do on your own gun. You’ll have to conduct your own expansion tests also, as CHUCK did. 


what I’ve learned in reading about guys that have used and still use slugs successfully, is they all share the same thing- hours upon hours of testing, and dollars upon dollars of buying different types and weights. No short cuts with the slugs.

Although into Airguns extensively even prior to the "Old Yellow" in its hay-day. I reside in Sausalito and was right close to Beeman's Orig Opening in San Rafael Many Moons ago.

Have seen a bunch of transitions but none more exciting that the current Tech. Dev. & Slug transitions bringing these platforms Very close to approaching the power of a .22 long Rifle. With that said (& somewhat verbosely) it brought me to this Airgun Nation after the YELLOW went south...........so forgive me in: How do I search " Chuck Threads on this forum?

On your MK II you are pushing 34 grns very well @ 1007..........However the issue I have w/ Pellets is the design and Velocity drop off quick due to the Skirt DRAG!....Enter the Hybrid IMO! possibility.

Might you give me a projection on the New M3 as to the proper possibility of correct twist / barrel that is current on the Compact.........

From watching Ted's vids and his research that is sent to FX for Dev. I noticed Ted was getting Great groups w/ the Hybrids pushing 980 FPS albeit in a 600 mm barrel. Most of the new barrels supplied with the M3's are based on this research for the optimum config. and alot of that was w/ the Hybrid slug n' .25 from my research...Can you confirm?

As to your comment as to Hours and Hours of testing & no way around it ...I concur to a degree...However, the reason I am hoping to get others to chime in is to cut down on said hours although I an highly willing to have fun putting in the time Jus wish to cut to the chase!

If you want your Hybrids to shoot 980fps, that’s the equivalent of a Hades going 1,020fps. That my inquisitive friend is really pushing a Impact Compact. You are going to be draining that 300cc tank quick. Guns, even the legendary FX Impact have let’s call them happy zones. There is a zone where the 500mm, 600mm and 700mm barreled guns can just coast along, remain reliable and be efficient. What you seem to be wanting power wise is where the 700mm Impact cruises. I don’t even push my 600mm Impact into that zone. Why do you think they make 3 different barrel lengths? Hint, it’s not because they believe guys think goose guns look cool. It’s for making big power without killing the gun harmonically.

Vetmx:

Thank you for your insight. I am Not concerned about Air / Volume as in my hunting approx 20 shots when real stocking/hunting is all that I need... I am of the belief that the 300 cc tank should suffice at which time I shall return to car and fill my 300 tank via 12V compressor.

As for pushing the platform, I concur less is more mileage. So with that in mind and thanks....I am in hopes W/ the new M3 being a bit more efficient both with valving and W/ Plenum size the platform will go to approx 980 fps + or - with the 26 grns n' .25. As for barrels I am only to well aware about length trade off's! 

Like Many things without proper questions equipment can become an overkill i.e. stereo gear, T.V.' etc. I am seeking the Best mouse trap in a Short Light weight config. As I see it a 700mm barrel and possibly even a 600 mm barrel (however remain open to the 600mm) may be an over kill? I am more than willing to back off in FPS should I find that I am pushing the envelope to far, so yes, rolling back to 960 at maybe 85% of max is where I wish to be. Thus far I have Not heard from any Real first hand users with Actual use in a comp[act FX , so remaining some-what rational ~:)...... I do not feel I am pushing the reliability envelope too far?

Note: Taken off Z internet " 25 Caliber Hybrid Slug obtains the best accuracy when shot between 930 – 970 fps. With the initial offering of the . 25 Hybrid Slug weighing 26 grains, this will provide 45 ft lbs of muzzle energy that will shoot very flat and provide impressive expansion due to the design of the Hybrid. The 26gr ."

Do you have any first hand / User knowledge in the Hybrids @.25 cal w/ 500mm barrel?

Thanks

I have shot them out of a 500mm superior FX barrel I built for my RTI in .25. That’s why I bought a 600mm Impact. I shoot them at 935fps with the reg at 125b. The gun does it effortlessly and the crosshairs don’t budge when I squeeze the trigger. I didn’t buy a bunch of do-dads to make my 600 perform like a 700 and it shows with how consistent and accurate the gun is every day. My advice is just order something. Every day you waste wondering around in a state of confusion and indecision is a day you could be on a waiting list. Another thing is if all these posts are a reflection of how you are about decisions, the Impact is absolutely the wrong gun for you. You need a Benjamin Disco.

Ok then a Mrod. The Impact is a gun that will always leave you second guessing your decision to stay with a tune because if you change your reg, HS and VLA settings you know you can find accuracy again. But will it be slightly better, slightly worse, or only good on Tuesday and Thursday. There is always some new invention that makes you question if you are getting the most out of your current setup. The simple answer is if your gun is accurate, consistent and you use it for killing, leave it alone. But if you’re a second guesser, you might spend more time on spin cycle chasing things than actually enjoying the gun for what you bought it for. That’s why I’ve always admired my Taipan. Had one before they became cool. It is what it is and it’s a brick. No way to improve a brick. It shoots great even with an out of whack tune. Buy it, set it and forget it. Aftermarket accessories not necessary.

Glem:

Sooooooo! you are saying a M3 can Not push a .26 grain slug to approximate..980 fps...CORRECT?.......(Not 34 grn NSA or Knock Out)...what your are saying is that it impossible? Fine I am willing to accept that if this mere physics applicable to the M3 platform.....To date I have Not heard from anyone who has used the .25 Hybred in even a FX MK II Compact?

Should I get a few more suggesting I indeed am chasing Absolute rainbows w/ 26 grns n' .25 5OO mm ...Done Dea!l...it will be the 600 mm.

Should have no problem pushing a .26gr slug at ridiculous speeds.

But seriously I doubt you'll have any problem sending 26gr to that speed its only 45fpe or so.

The easiest way to make life simple in the pcp world is listen to the gun and take what it gives you. I’ll bet Glem is a 700mm guy. Guys that want to send poop fast don’t cripple themselves with short barrels. Why hammer my 600mm to get what Glem or Centercut do in their sleep with their 700’s. I took what my 600mm gave me and am happy with it. If I had a 500mm Impact, I would expect 900-910fps with a Hybrid and a very sweet efficient tune. Plenty for killing stuff at tiny gun distances. Can you push them harder, yes, but the gun gets ugly. It gets more and more difficult for a clean follow through with a gun that’s got some bad vibes going on because you’re pushing it too hard.

I have 500, 600 (for the Boss) and 700. That new impact I'm setting up as a compact but I've had the 500mm setup over a year.

I didn't have any problem getting 80fpe out of a .30 setup last summer and was able to keep the reg relatively low. 110-120bar IIRC (500mm)

Long story short 45fpe with a .25 wont be a problem.

But like vetmx said the gun will buck a bit more and will be trickier to shoot.

Your experience is more in line with my findings thus far in my readings via the internet. I simply want the Possibility to be put to sleep this would Not be possible. I believe it is indeed possible to achieve the aforementioned said 980 fps in .25 cal w/ .26 grns.

*Some have suggested it is not possible, others say it might be but I will ruin the Gun?

On the new M3 platform is where I wish to pursue the Compact Barrel @ 500mm. Your hands on experience albeit via a "Boss" and IMO the Boss most probably does Not have the efficiency of the New M3?

Seems as if in the end the M3 Compact may well be the way to go for a compact hunting gun used for walking through the forest. I will Shoot (so to speak) for the 980fps and as you outlined, I may indeed roll it back to Not " Bark " and suffer the lack of accuracy that I may or may not, have to that end is where it shall become intriguing. As you can probably observe I am Not easily swayed by negative Nay Sayers.

This in theory seems quite do-able IMO!......and I Shall report back with my findings. There are most probably others that Might wish a Nice .25 cal light weight and short platform for similar hunting applications...If indeed I were to do serious paper Punching or shooting birds at 150 Yards while remaining stationary/fixed position, I Would oppt for specifically the 700 mm MK3 or DW.

I only mentioned the Boss for the 600mm. I've shot the impact in 500, 600 and 700 in .22, .25 and .30. You seem to bloviate a lot in your posts. Cut to the chase.

Yes the gun will do it. (Period)

If you really push it with a 500mm the gun will do it but buck more during the shot cycle which many have mentioned. You can get used to it. No it won't damage the gun at all.
