Question:OK, it has been a month since I asked this question and I still have not seen this item updated with its muzzle energy output or at least the velocity of the round from which I can calculate its muzzle energy.
Seriously, would you buy a car without knowing the horsepower of the engine or what kind of gas mileage it gets?
Why is this so hard to get from Federal?
Response:I am very sorry Ronald, I do understand your frustration. We are trying here but no success as of today. Thank you for your patience.
Question:I have a typo in my follow-up comment: It should read, " I used American Eagle 50gr JHP which have a muzzle energy of 1227 ft. lbs." and not "muzzle velocity"
Question:Having not received any info on the ballistics of this round, I decided to purchase a box and do my own testing. Unfortunately,I don't own a chronograph, so my test results will be subjective.
I had two other .223 rounds I wanted to try out:the Hornaday 75gr. SBR Interlock HD - a round made for 11.5" barrel that I wanted to see how it would perform in a mid-length AR with a 16" 1:8 barrel, and the Fiochhi 55gr V-max(bullet made by Hornaday).
For my benchmark, I used American Eagle 50gr JHP which have a muzzle velocity of 1227 ft. lbs.
These frangible rounds had slightly more felt recoil than the AE JHP's and I'd say they fell between the AE JHP's and the PMC .223 55gr FMJ's I use for target practice which have a muzzle velocity of 1250 ft. lbs.
The Hornaday 75gr SBR rounds worked just fine in my 16" barrel mid-length AR and were similar in felt recoil to the Fiocchi 55gr V-Max which have a muzzle energy of 1208 ft lbs.
My next test fo these will be for accuracy but my main purpose for testing these rounds - except for the Federal Frangibles - is to use them for home defense and not long-distance target shooting or animal hunting.
Response:Thank you Ronald, many of our customers will find this information very useful.
