Home Forums Reloading Varmint Rifles 223 remington twist rates

Mr.ImitatedOften:

I agree with Keith and others on their point; the 75 gr. bullet in a fast twist [1x7-10] .223 or .223AI is traveling at a much slower FPS (3000 or less FPS range) than a 40 or 50 gr bullet in a 1X12 twist (3300-3700) .223Remington, thus the trajectory is much flatter.

This is a result of the relatively long length and weight of the 75 gr. bullet, the need to seat out further rather than in or sacrifice even more powder capacity.

The flatter trajectory of the lighter bullets (0-250 yeards) allows the owner to just do more things...AND the 1X12 will still shoot a 60 gr bullet well, always shoot the 40 gr. well, AND shoot the 70 gr. Speer SP bullet !!!

I don't hear much on the frangibilty of the 75 gr. bullets in the fast twists; an important consideration i.e. ricochet reduction when hunting in /near populated areas and farms.

So, the faster twist rifling is the best of both worlds for versatility in the .223 calibers.
