Old jsb.177 monsters vs. redesigned?

[nomojo65]

Ok, I know this probably has been discussed countless times before... but, for 25m or 50yd Br has anyone found that even though the slight edge in accuracy usually goes to old style!, Exceptions being... in windy conditions? where I am seeing a trend where my scores might actually be better with the re-designed pellets? Now I know each barrel is different and shooting in the wind is very hard to get consistent, quantitative results? I am shooting these old & redesigned jsb’s through two different LW POLY barrels which behave similarly!, anyone seeing similar results? Or am I just wanting this to be the case... Also the Redesigned’s shoot about 10fps slower, without any adjustments to reg or H.S., will add this, I can get them to shoot more accurately if I bring fps to roughly 830fps or higher? but then relegates me to shoot out of the H.V. Class!

The redesigned pellets do not work in my poly barreled Steyr at 810fps (faster fps is too much for the permitted 20ft lb energy in FT). They also shoot about 50fps slower.

Ya I know skip, that’s why I said if I bump them up I can’t shoot in HV CLASS in USARB sanctioned events either!, but they do seem to perform slightly better! How fast could you get them? Or did you just stop @ 810fps

FWIW the "redesigned" diabolo-shaped Monsters don't shoot well at all in my poly-barrel RAW benchrest gun. The old style is much better, and others at the range agree.

Ya, probably just a anomaly on my part?, I still have to do more testing outside in the spring, just can’t ignore what I’m seeing though that if I bump them up to shoot 810-815fps they seem to do better especially in the wind? Probably wasting my time!, if not ,everybody would be using them... I will tell you what started all this for me was the fact that one of my barrels just refuses to shoot anything smaller than 4.54 head dia. And the initial run of redesigned monsters had that consistently larger head that this barrel prefers so I guess I’m just looking for a glimmer of hope!!!

I just stopped at 81fps. I have an LW barreled rifle that shoots 10.65s at 910. I should try the redesigned ones in it. Once it warms up, about April. Thanks for the idea.

 

[nomojo65]

I’ve never tried them in my 12 groove LW either! Think I’ll try indoors first & see what happens? Suspect I can’t push them fast enough in that gun?

im following this post!

 

[Crusher]

Yeah me too. In calm air in my back yard I've shot tons of both through my TM1000 with LW poly and I don't really see an advantage of either. I'll follow along and see if we get any further into.

Only shooting the OLDER straight waist 13.43's & as luck would have it still have 1/2 dz tins.

Did try some newer ones and shot side by side to what i have & guns set up for ... Happy to have 'Some' older style ones to last a bit longer.

 

[nomojo65]

Well mind you I have no conclusive or definitive results as of yet! but this seems to be the case with ONE of my LW POLY barrels indoors @ 16.5yds, I can see no accuracy differences between the original monsters and the redesigned monsters ( in this particular barrel ) now this summer I was doing some “wind” shooting @ 25m for hold offs etc. and was doing terrible! Sooo... thought well what the hell I’ll try some RD’s not to waste my competition pellets, My scores were better?, now there’s many variables at play here but this one barrel may just shoot these? please if anyone has extensively tested these Rd’s share your findings!, I don’t want to have to fit another barrel to this gun, it only shoots very large dia. Pellets! Not cleaning helps!, but I don’t know when accuracy is going off? usually right in the middle of a card... my x count has really suffered with this barrel

hello guys i am new to this forum but i know a lot about balistics and airguns, next week i am getting hatsan 125 sniper in caliber 0.177 so my question is do you think that a 16 g pellet form 0.177 vs 16 gr pellet 0.22 same gun same power plant woluild have be beter on 0.177?????

 

[nomojo65]

Thought I would post pics of some preliminary groups with old & redesigned jsb .177 13.4gr monsters first pic. Shot w/BM-500, indoors @ 16.5 yds, you will see a fouler group followed by 3-Record groups for each style of pellet- also note the groups @ bottom under drawn line are RD’s from a different lot but same head dia? (All RD’s 4.53 head dia.) next pic I decided to try them “RD’s” in my TM-1000 W/ LW-12 groove barrel, these shot @ 735fps?... I did not adjust Regs or hammer springs on either gun the BM-poly barrel was shooting the RD’s @ 790fps this doesn’t suprise me from either gun considering my previous chrono results.

I've tried both in my LW Poly barrel and it definitely likes the older style better.

I would love to revisit this topic..... as i was recently told the redesigned pellets came about because Daystate didn't like the way older JSB's performed in their guns.... anyone in the know please chime in. I'm all ears, curious ears at that.

I have to aggree with you there NOMOJO!! When the first came out they were awesome!! large heads and shot great! As time went on they got much more inconsistant for sure. My RAW with the Poly barrel shoots the old monsters better @ 25 yards for Indoor benchrest but at 50/55 yards outdoors for field target the redesigns are a bit better. That is with a good batch!! Few and far between!! J.L.

 

[nomojo65]

I am under the impression that jsb came out with the RD’s to satisfy the longer ranges and higher velocity’s of the manufacturers HP guns? They tend to stay stable past 50yd. Which seems to be about the limit with the originals at 820fps.

The RD’s can be pushed at much higher velocities and need to be for stability out past 50yds. In my higher powered.177 guns I’ve owned (Daystate/FX) I normally had to push them 840fps right up to 890fps to keep them happy out to 75yds.

 

[whitefox545]

I shoot mine at 945 F.P.S. and shoot pigions and starlings with regularity out to 140 yards using my Red Wolf Safari It's a killer combination. J.L.

 

[Gear_Junkie]

I've tested both extensively in my LW Poly barrel, to try and find out which one was more accurate. I'm also shooting hunter field target so i have them moving at 805fps +/- 5fps. I've even tried multiple batches of each. NOT CONSIDERING WIND, both pellets shoot with equal accuracy as best i can tell. However, the RDM's are much harder to load... so I only shoot the originals

 

[extradrygin2001]

From what I have read and my own experiences the redesign are made for higher velocity, the original are for velocities around 800fps to keep them within the 20ftlbs limit of field target.
