So, you've shot them over a chrony and got those BCs, or are they just the ones mentioned in the advertisements?

The ZAN Projectiles .22 ELR are now available !!!
- Thread starter ZAN
- Start date
You know it. I'll use G1 on these since it'll be under 950 fps, probably around 900 to 925... Screen shots of the FX Outdoors Chrono is best. You shoot them from the LW 1:15.75 barrel and I'll do the same from the FX 1:16 liner.

Hello,
This will reply on most of the questions above.
Yes they are different from the main idea a year ago, due to many reasons.
Those have hybrid diameter if we can say so. Their diameter is between .217 and .218 and this makes them shooting good in all of the fast twist barrels that we tried until now. And no they are not made around FX liners only.
Due to hybrid diameter we don't think for now any additional diameter is needed(Please do not measure them with 30$ calipers as this won't give you any answer.)
Shortly there will be other weights and calibers coming. We are not gonna say exact dates but soon.
Weight in this case is misleading, due to few reasons. First those slugs tends to work best at speeds around 935fps. Second their bearing surface is due to boat tail much shorter then with most heavy slugs. So for example if you are shooting 33 grains at around 980-1000 fps, if you swap them with ELR you get speeds just around 935 fps. So you don't need to go with stupid high reg pressures on the rifle.
I hope it wraps up most of the questions.
Have a great day,
Žan

I mean, PRS rimfire is .22 cal. With the advancements in airguns and ammo happening, you can't expect them to remain more or less unregulated forever. Even rimfire has restrictions, such as standard velocity ammo only, nothing supersonic. I would not be surprised to see more restrictions on airguns in the coming years. A 49 gr .25 cal Altaros slug with a G1 BC over .21 is practically unfair to 22LR already. The best rimfire G1 BC out there now is for Lapua at about .172. I shoot the Altaros .22 cal Kings, and I have a noticeable advantage in the wind.
If manufacturers want to make airguns more competitive, build better chassis and air systems.

Thank you for your reply. I recognize your experience and expertise in PRS.
If PRS allows multiple calibers in Airgun then scaling the max weight by caliber would keep each competitive, at least for external ballistics.
For example, an 40gr limit in 22 cal
equates to 52gr in 25 cal
75gr in 30 cal
I had no idea 22LR BCs were that much lower than Altros slugs. I know 22LR ammo has a step down to fit into cartridge. That degrades BC.
To a certain extend restrictions prescribes the design solution. That limits innovation and improvement.
The BC advantage Altaros slugs have could quickly disappear when Lapua develops higher BC ammo, maybe that isn't part of what the PRS community wants?
It's not that airguns are easily out scoring 22LR?
Thanks again.

I think an FPE limit would be much more fair. A .22 subsonic Rimfire going 1080 fps is 103 fpe. If an Airgun slug of 49.5 grain is shot at 900 fps that is 88 fpe. Quite a difference. And even a 40 grain slug at 950 is 80 fpe.
The difference in BC is not the only factor. We can talk advantages/disadvantages all day. Should rimfires be penalized because their lock time is 1/10 that of an Airgun? There are pros and cons of each, to take away any pros seems kinda silly when Airguns still have to live with the cons. It appears that the PRS Rimfire guys are preemptively reducing Airgun competitiveness so that they won’t be overtaken by Airguns in the next couple of years.
Make the limit 105 fpe and be done with the childishness. NRL-22 doesn’t seem to worry about it.
Airguns are getting close to rimfire but still have a ways to go. Why limit them until the day they start to finish top 10 in National matches, which hasn’t happened yet, not even in the top 50 PRS or NRL22.

Today i shot a few groups with the elr slugs with 135 bar and hammerspring just under 3. This is what normally i use with the altaros king 5.52 40 grain on my panthera. The speed was about 10fps lower than altaros but easy 925 fps. 5 shot groups are easy within an inch so the slug is promising. For the first time really good. Next week we have our first match so i do not have time for testing next week because the match will be shot with altaros. After next week i can test with other airguns.

Griffin makes elr slugs, you can shoot the 45grain that has a 4mm poly ball in the center, that have a large boa in the back and round dimpled front. The issue is these slugs are long and may not fit in the magazine. I shoot PRS with a daystate .25 air ranger, and notice there are benefits to using a rimfire when doping out to 369 yards. Seems that airguns are more like shooting at that range. When scoring it seems the rimfires have a advantage too because they are louder than an airgun using a moderator for harmonics. Also shorter barrels are favored to when you shoot through the various stages (ladders, large pipes)
I agree that everything should be called at a fpe limit that would keep the playing field equal
Regarding the weight, they won't allow slugs greater than 45 grains for .25 either (I normally shoot 57 grains griffin elr)

I hope you can make a lighter variation of the .22 ELR slugs. None of my airguns will even come close to shooting a 40 grain slug at 935 fps.

Why are airguns allowed to shoot larger calibers? If the competition calls for .22 caliber then everyone should be shooting .22 caliber. Giving airguns a handicap is stupid.
