It’s time to see if the hype is real!

Looking at the actual round pictures, they seem to have a smaller meplat diameter than shown on the tin lid pictures. Meplats need to be smaller than about 65% of the projectile diameter to keep the drag low, but it will depend on the projectile speed.
Does this hold true about meplats? it's from wiki, so not the best source of info

Trimming the meplat (cutting the tip of the bullet, thus increasing its area) decreases the bullet's ballistic coefficient, increasing drag, and making it more susceptible to wind drift. So even though the grouping will be tighter, the time of flight and wind drift will be slightly greater.

the time of flight and wind drift will be slightly greater. YES but you can compensate for both and achieve tighter groups .

For supersonic speeds of bullets, yes it is true. For subsonic speeds no, it is not true up to a point (the meplat value I mentioned).

I shoot these at 50yds and they seem to be doing well (for me). They are very similar to the ones above by Zan. I have not tried them at longer ranges, so I can’t speak to how they do at ‘extreme longe range’.

These are swaged in a die I made.

Those look well aged 😀
 
I have 2 mid powered .22 caliber slug guns that I used for the test. Neither are "maxed out" as I prefer the dynamics of a smooth shooting airgun over a "strung out" airgun.

Here are a few existing profiles I pulled out of my Element Ballistic app:

FX Panthera 600mm 1:18 set to shoot 30.5g ZAN slugs at 970 FPS with a G1 BC of .12
FX Panthera 600mm 1:18 set to shoot 30g H&N Precision slugs at 980 FPS with a G1 BC of .12
FX Panthera 600mm 1:18 set to shoot 34g H&N Precision slugs at 940 FPS with a G1 BC of .13
RAW HM1000x 24'' 1:17.7 set to shoot 27g H&N slugs HP II at 1020 FPS with a G1 BC of .11

I did not change any settings when testing the new ZAN 43.4g ELR slugs. These are my initial results:
FX Panthera 600mm 1:18 at 845 FPS with a G1 BC of .143
RAW HM1000x 24'' 1:17.7 at 810 FPS with a G1 BC of .167
FX Panthera 600mm 1:18 at 845 FPS with a G1 BC of Altaros 40g slugs (from this past summer) at 880 FPS with a G1 BC of .17

Others have reported a BC of +/- .2 at either faster (940+ FPS) or slower (650 FPS) but I'm not sure I want to re-tune either of these airguns!

That's all for now, I'm off to SHOT Show 2025

Thanks. The mentioned BC that other “influencers” have reported, we noticed one of those was not accurate. The 5 captured speeds at different distance wasn’t being captured by his FX chrony (1 of 5 or 0 of 5) and the sample data was very limited with the last captured BC being way too high for reality and thus skewing results. To quote @AirNGasman : The truth is fantastic enough for my purposes!

Safe travel Mike!
