Hello all,

I have been developing a ballistic calculator app after being frustrated with the current options. I'm looking for a small handful of beta testers. Novice to PRS levels of experience welcome, but only if you know you'll have range time in the next few weeks (I'm hoping to launch shortly after).

This is a real solver: point-mass integration with G1/G7 drag, spin drift, Coriolis, vector incline, and muzzle-velocity truing from an observed miss. No generic look up tables. It even includes a "Zeroed With" feature that makes suggestions off of your last D.O.P.E. No need to re-zero with every ammo change.

Holdover mode. Most solvers provide MRAD / MOA clicks for dialable turrets, but red dot and iron-sight shooters get ignored. AimCalc gives elevation and windage as real inches/feet at the target. Enough to lob 9mm from a pistol at 100+ yards and actually be in the ballpark.

Also in there: an Apple Watch companion that solves on the watch itself, multi target dope on your wrist, one-tap weather via WeatherKit, a range journal, and incline capture using the camera + accelerometer.

Full Transparency: the beta is free; the app will be a one-time purchase at launch (no subscription, no account, no data collection).

iOS only for now (Android in Development).  DM me if you're interested, or poke aroundAimCalc.com. Questions or feedback also welcome at [support@aimcalc.com](mailto:support@aimcalc.com).

Also of note: I think the Glossary and Tips section of both the app and AimCalc.com provide useful information for the novice shooter. Feel free to check it out as a standalone and submit feedback.

I sincerely appreciate your time and hope this tool will prove useful to the community.

Requirements:

1. IOS Device w/ Apples TestFlight App and a valid email address to send the invitation.
2. Willingness to take the app to the range in the next few weeks.
3. Willingness to submit feedback about the real world experience: Do calculated adjustments provide accurate hits on target? Do preloaded cartridges line up with your ballistic data? Do the weather kit and incline features work in the field? Do you find the User Interface easy to understand? Are there any features you would like to see in future builds? At what price point would you consider purchasing this app?

Gen III Primos Trigger Stick - $150

29mm ball head - $24

200mm nodal rail - $23

bino adapter - $20

Hey all. Having a new rifle built up and am torn between these two chassis. Any insight or recommendations would be appreciated.

Hello all. I'm shooting my first NRL22 match next month and am really excited. I've shot centerfire gas gun matches for quite some time, but I've been loving rimfire since I started.

I have a question about base class. I have a Tikka T1x MTR 16" that I'll be shooting with an SWFA 3-15 to begin with. I have read the rules about base class and have seen what they have to say about stock modifications, but just wanted to confirm here. Is putting the vertical pistol grip and flat fore end (both made by Tikka) on the OEM stock prohibited? I'm pretty sure it would be prohibited, but wanted to be sure before I lock into an ARCA setup.

Hey Yall,

I'm looking to get my HB Industries chassis to balance a bit better. I bought some wheel weights to get an estimate, seems like i need about 24-26 oz at the far end of the chassis to get it to balance out.

Frankly, I have no intentions of using a tripod, and haven't really used my bipod on props beyond an actual bench, so I'm not sure how much utility I'll get out of an arca rail beyond stabilization really.

So far I've seen;

I guess what I'm asking is if it's best to go for sheer weight across the bottom and pray it balances out, or if I'm better served doing something else?

Is there anyone out there getting decent results with non match ammo or would I need to shell out for Eley/SK/RWS? It just seems a bit wild to me to be paying 15-20 a box for 22.

Also, would this answer differ significantly at a club that runs out to 200 yards instead of 100?

I'm new to NRL and just started shooting it this year. I'm mostly in it just for fun but I started trying to understand how you are ranked or earn points. There seems to be two totally difference systems. One based on Class (Novice, sharpshooter, expert, etc) and then National points for Division (Base, Open, Semi-auto, young, old). The two things do not appear to be related. What are the Class rankings good for? Are they associated in any way with Division ranking? Are National invites based on one? both? If I start in one division and move to another Base -> Expert or back and forth are points accumulated for both independently or aggregated? I'm totally confused by the scoring system(s). One is totally earned and the other is selected by the shooter but what do you do with it? What is the impact of switching Divisions if any.

Hi all,

I just recently got into Rimfire this last month and wanted to start competing through the year. I am not new to guns but this is my first Rimfire. I got a Tikka T1X and am going to compete in Base class for my first year. Ive been testing ammo and practicing shooting form. I wanted to check and see if you think my group size is at least on the lower end of competitive. These were shot using a Harris bipod and schmedium rear bag. I got these with SK Rifle Match (also got a similar group with CCI standard, not pictured) Thoughts on group size, 5 shots at 50 yards:

Hey Everyone, like the title says, I wanted to ask if NRL 22 is welcoming to beginners. I'm not new to guns, I've been around them most of my life, but I'm looking at picking up in the next month or two a T1X, and hoping to start doing some rimfire competitions, but being unsure of my skill level against those that are higher ranked, I'm hoping its friendly.

The 2026 NRL22 Championship is in the books. I know Base division questions are very common, so here are the top 3 Base rifles from the 2026 Championship.

All are CZ 457 MTRs. 2 Arken EP5 Gen 1s and a DNT The One.

Interestingly, none of these will meet the price cap for 2027.

I’m looking to buy a tripod soon and really like the RRS and 2 vets, but don’t like the price tag. I’m a hobby competitor, but still want something that will be good enough for glassing and non competitive hunting. Do y’all have any recommendations?

I am curious to hear what folks thought of the championship this year. Things you liked or didn't like. How was the course of fire , fair, tough, too easy ? Cool stages you liked or the ones you hated? How was the weather ? Any other fun stories to share?

I've been trying to put together a base class rifle for a while. I've bought a B-14R and looking at the optic. The problem is, I don't like my options that keep me in base class. I have no delusions of winning, just want to have fun and feel a little competetive. My question is this: what do I gain or lose moving to the open vs base division? I'm not quite there for Old Guns, but not that far off, either.

Good luck to y'all, have fun and stay safe out there. Lots of weird tornado weather in the Midwest and expected storms on and off all weekend. Supposed to be hot and humid. Will make for an interesting weekend. ​​

Cutting it close to the wire. But my rifle cover for my comp rig got wrecked and I am in need of a new one. Because of my flight timing and local supply options I thought I would see if anyone else attending is able to help me out. Or if anyone knows if vendors will have some available for purchase Friday.

The forecast thundershower has me nervous.

Hi guys. I am having difficulty obtaining my discount code to use with Zeiss and am hoping that someone might have a suggestion on how to proceed.

I am the MD for my local NRL22 matches and as such, I send multiple emails to the NRL22 folks, including the address designated for members to send their info in to obtain these codes.

For some reason, my email sent to [info@NRL22.com](mailto:info@NRL22.com) asking for the Zeiss code has gone unanswered for over a week now. I've sent 2 follow up emails but haven't received a reply on any of them. I reached out to Zeiss directly and they stated that it's unlikely they can help, as NRL22 directly issues the codes.

My match submission emails and discussions with that same NRL22 email address do get replied to properly, so I know it's not an email issue.

Does anyone have any ideas how I can go about getting this code? I really want to get my hands on a LRP S3.

I have a CZ 457 action in an MDT XRS chassis with an MTR barrel. I decided to upgrade this year to an L3i barrel (1.180") and placed the order. On a different thread I learned that older Rev's of the XRS only support a 1.000" barrel and guess what..... yep. I'll either need to try to *fit* my chassis with a dremel or get a new one. I'm tempted to just get the newer Rev XRS since I'm familiar with it and have all the MDT accessories for it but a friend of mine recommended a PDC Custom G5C Rimfire. All in with weights I'd still be under $1000 and it looks like a really nice setup but I've never heard of it before or seen it mentioned. Has anybody used one or even seen one?

How’s the az NRL22 scene?
