I have been using this for a month or so. Easy to use, and I'm using it for bullet trajectory 0 to 50 to 200 yards. It seems to be accurate
but given I'm new to the AR world, I thought I would ask about other easy to use calculators that you like.

Thanks!

I use hornady on my phone for quick calcs. Its a free app and I do use a lot hornady bullets anyway.

The 2 I purchased and use are Sierra Infinity 7 and Ballistic Explorer. Another decent freebie online calc is Shooters Calculator .

Check out the free version of Strelok+.  

It is an extremely robust and easy to use ballistic app.  It can be as basic or detailed as you desire.  The Pro version is only $10 dollars.   It not only calculates holdover or hold off and such at various distances, but generates charts and "dope" cards.  It has a "through the scope" feature for hundreds of scopes and reticles both first and second focal plane scopes.

It also has preloaded BC for many different specific bullets, can connect to other apps you have loaded to take into consideration altitude, temperature, barometric pressure and such.  Can calculate and compensate for spin drift based on velocity and barrel twist rate.

While many features mean little at only 200 yards, they can make a huge difference when you move out to longer distances, or even at 100-200 yards when shooting .22LR match ammo.

Check it out.

I have the Pro. Pretty sweet. Wish they'd move away from FB. I also use a chronograph which I really appreciate. So far I haven't hit it at distance.

Ill second this. Strelok generates very good dope with the caveat that your inputs need to be precise. It matters very little at 200 but get out to triple that range or more and it will get you very close with ease.
