I do like the 17 Center Fires....I also like the 22 Hornet...Most excellent fox guns the 17's and the Hornet.
I will sometimes take the Remington gun and ammo catalog and compare bullet velocities and energy. to do this go to the factory bullet area. IT list the factory ammo muzzle, 100, 200, 300 etc yard velocities in fps (feet per second),Energy....same muzzle, 100, 200, 300 yards ft-lbs (foot pounds) the short range trajectory and long range trajectory at 100, 200, 300 yards... chart shows what primer Rem uses for all the rounds. You could check the velocities and bounce it against the reloading data velocities and determined what powder you can use to equal factory ammo velocities... All kinds of data Can be determine by bouncing same grain bullet and type against different calibers..
For example The 17 Fire Ball and the 17 Rem velocities, energy, and trajectory are real close... The Hornets energy drops down almost half compared to the to 17 CF... How many times have you seen post by people asking if the Hornet was a good coyote gun...It is but just by looking at the energy you sure can tell if it's better then the 17 CF or a 223 or 22250 or 220 swift etc etc etc.
Let see? the 17 Fireball 25 Grain HP energy at 100 yards is: 597 Foot Pounds and at 200 yards energy is 429 foot pounds. the 22 Hornet 45 grain hollow point energy at 100 yards is 417 foot pounds and at 200 yards the energy is 225 foot pounds. SO based on Energy alone I would rather be using a 17 Fireball instead of the 22 Hornet for coyotes....
By the way I am not bashing 22 Hornets either... I do own this caliber too and like it a lot for chucks and fox out to 150 yards..
The charts can help you pinpoint that perfect gun too... do you want a 222 Rem, a 223, a 22250, or a 220 Swift based on velocities, energy, and trajectory. Maybe the 22250 energy is a bit much and you should buy a 223 or a 222 for bobcat or other predators.?
Save those Rem books and use them to determine if your gun is adequate for different game or use IT as a guide if you reload and want a load equal to factory ammo based on velocities. Simply find the velocities equal to the factory velocities for the bullet grain your reloading.
