The ZAN Projectiles .22 ELR are now available !!!

I tried to shoot the ZAN ELRs (.22 42.3gr ) from the FX dynamic 700mm (stock configuration, superior heavy stx).
This rifle easily gives 1 MOA at 50 and 100 yards using Altaros 40gr @ 880fps.
With the ELRs I was barely getting 2 MOA (tried only 50 yards).
Tried different tunes, with velocities from 860 to 940 fps, ~500 rounds total.
The chronograph shows consistent velocities (attached), no wind.

Does anyone have experience with ELRs and FX dynamic 700mm?
Any gotchas? Lubrication? Barrel cleaning? Specific velocity or tune?

The price of ELRs is very attractive, I am eager to try them a few more times, but they need to be at least close to the Altaros
Thanks!

Has anyone tried these in a standard fx impact m4 magazine, will they cycle okay? I've got an m4 Extended I'd love to test these if possible.

I've also got Eagle Vision mags which say they'll take 11.5mm flat head or 12mm domed, I assume that would work?

I'd like to compare the .22 ZAN ELR 42.3 grain to the .22 Altaros King 40 grain and will do so in a couple of weeks. Will be in Phoenix this weekend at the Sonoran Desert Classic AAFTA. So, the following weekend.
Although not apples to apples, I did compare the ZAN ELR .22 at 905 fps from 1:16 barrel to the .25 Altaros ATP Smooth 49.5 at 890 fps from a 1:18 barrel a week ago. At 100 yards in breezy (but not windy) conditions, the ZANs would do approx. 1 to 1.25 MOA. The Altaros .25 would do between 0.75 to 1 MOA consistently. So, in this case the nod goes to the Altaros @Altaros. FYI, the ZANs ran about 0.165 to 0.170 G1 BC, with the Altaros at approx. 0.195 to 0.200 G1 BC.
When I do compare the .22 versions, I'll shoot them from the same barrel at the same speed. More to follow...

One more experiment: ZAN 42.3 gr vs Altaros 40gr, both in .22 cal.
Clean the barrel, then shoot 2 mags (34 rounds).
Same FX Dynamic 700mm, same tune, same conditions, same shooter.
ZAN @ 853 fps
Altaros @ 875 fps
I like the Altaros's groups more.

Any recommendations on improving the ZAN results?

Increase your speed

Todays results after turning up the reg used about half the 4 inch gong at 300 yard's ,so 2 1/2 to 3 inch group wind quartering at around 6-7 mph . I'm happy, we'll see how tomorrow goes with 10-20 winds. Oh I found the airgun setting LOL .

Edited the post it was a 4 inch gong not 3

14C 987hpa 38%. Reg 166 micro slighly less 3 (33g hammer). 960fps. 120m(7° slope)

Hi all, i m pretty new here so appology if i miss some etique. I ve got 700mm panthera(.22, 34g hammer,slug pin, humma 1st stage reg set to 200bar, lot of weights on chassi...nothing special). I tried several reg setting(150-160-170-180), seems best results around 165 bar(166-167 on digital gauge), it give you 290-300 m/s depend on weather/altitude, 295 seems best for me thus i got no POI during day, i have mag(18+2-3 purge shots, 290 bar/360cc bottle) that s my experience from 4000 slug shooted already. I posted some of my groups upper here, if it is under moa,I can live with that, never shooted altaros tbh even o got them at home...too expensive for purpose i shoot(even for me who pay distributor prize)
