2bit. The bullet drop at 300 yards is going to be totally dependent on what distance you have the rifle zeroed for and what bullet weight and configuration you are shooting. In other words, if the rifle is zeroed for 100,200, or 300 yards the drop will be different. With respect to bullet weight a 40 grain is going to drop less than a 60 grain ...
Download a ballistics program for Excel. Enter you figures, highlight the columns you want, and tell the software to make a graph. In this way any changes you need to make dependent on your situation your graph can be updated. The one I found I also hid the columns I do not need.

I took a photo of the 25 yard chart because if it's accurate It looks to me like the best option for me. It starts out impacting 1.2 inches high at 50, 2.1 at 75, 2.7 at 100, 3 inches at 125, 3 inches at 150, 2.6 at 175, 1.9 at 200, .7 at 225, - 0.8 at 250, minus 2.8 at 275, minus 5.1 at 300, minus 8 at 325, minus 11.3 at 350, minus 15 at 375 ...
The 6.5 Grendel data I have found has been zeroed for 600 yards as the table presumed the shooter is into 600-1,000 shooting. At least that's my guess. Those tables show a mid-trajectory altitude of 45-55 inches, which strikes me as odd for a round touted to be "flat shooting." All of the other calibers' ballistics data I have found is based on ...
bullseye, i agree with the others, if you were only varmint hunting,then go withe 22-250, excellent caliber, flat shooting and fast, gentle recoil. now if you were wanting to maybe hunt deer size game also, the 25-06 would be a better choice, good selection of varied bullet weights for varmints and deer sized game, flat shooting, gentle recoil. some have suggested the 243, also an excellent ...
Shoot slowly and allow the barrel to cool between shots, and it could last for 4-5 thousand rounds. I ran into the same exact issue, as far as choosing the .223 or 22-250. Unless you are going to shoot the gun everyday and put a lot of rounds through it in a short period of time go with the 22-250.
Montanacowboy. 33 posts · Joined 2011. #17 · Mar 29, 2011. Lindenwood, My load for my Ruger .44Mag is 24gr. of WW-296 Ball powder and the 240 gr. XTP which gives a 1413 fps avg velocity which is above what you like. It is accurate out of my gun. Shot only one deer with this load and the bullet performed very good.

The 5.7x28 was designed by nato for less weight, the 5.7 is wicked with energy in a pistol, delivering as much as 2800 fbs on a 30 gr bullet because of its pressure increase, I have cronagraphed 40 gr at 1900 fps with my FN 5.7, a wicked pistol and very accurate.
The Sierra Manual has a chart n the back of the book that will give you POI at ranges up to 500 yards for different bullet weights, velocities and zero points. Unless you're shooting competition, or varmint hunting, zero at 50 and call it good. a 50 yard zero on a fighting rifle will let you hold center of mass and get a hit out to 300 yards.
