Brocock/BRK Brand new .22 BRK Ghost HP

...I asked the Bing AI how many foot pounds an 18.13 grain pellet @ 960 FPS was making and after a lengthy exchange wherein I had to explain to it that I could not preform the calculations it finally gave me this:

Of course, I can do the calculations for you.
First, we need to convert the mass from grains to kilograms and the velocity from feet per second to meters per second:
  • Mass in kg: 18.13 grains * 0.00006479891 kg/grain = 0.001175 kg
  • Velocity in m/s: 960 FPS * 0.3048 m/s/FPS = 292.608 m/s
Now, we can calculate the kinetic energy in joules:
KE=21∗0.001175kg∗(292.608m/s)2
Finally, we convert this value from joules to foot-pounds. 1 foot-pound is approximately equal to 1.35581795 joules:
KEfoot−pounds=KE/1.35581795
Let’s calculate these:
m = 0.001175 # mass in kg
v = 292.608 # velocity in m/s
KE_joules = 0.5 * m * v**2 # KE in joules

# Convert to foot-pounds
KE_foot_pounds = KE_joules / 1.35581795
KE_foot_pounds

After running these calculations, the kinetic energy of a 18.13 grain pellet traveling at 960 feet per second is approximately 31.02 foot-pounds. Please note that this is an approximation, as the conversion factor used is rounded to eight decimal places. For more precise results, you may want to use a more accurate conversion factor. I hope this helps! If you have any other questions, feel free to ask. 😊



...it couldn't/wouldn't just say "sure, that would be about 31.02 foot pounds", but we got there...

...methinks it was showing off...!!!...LoL...!!!...

...I still don't know if having the regulator set at 100 bar will yield less or more shots per fill than 150 bar but intuitively I would think more...

...so I should see 150+ shots per fill...?!?...

...one thing Ray forgot to bag on is what a porker the Ghost is...

...mine ended up @ 11 pounds loaded, with a Mini Wraith 4K, 0 DB moderator, and BT 46 Atlas bipod attached...

...my Ghost HP was specified @ 7.5 pounds, but my scale has it a 7.8...

...I guess I won't be carrying it far...

A Ghost does end up with some heft after mounting a scope and whatever else. That 15mm OD steel barrel and big block of aluminum (mono block/chassis) and a 30oz scope etc is all gonna add up.

I've yet to find a situation where gun weight was detrimental when precision is required. In fact, most of the PRS/NRL and even EBR types are adding literal lbs to their guns, via accessory rails.

Traded in my Delta Wolf for a new .22 HP Ghost. Just set it up with a PARD DS 35 50. Also a new BR 4 Accutac bipod. I just wasn’t using all the features of the Delta Wolf. Plus I went to go ratting one night, and after I got to the farm, I realized my battery was just about dead. That was it. I really wanted the non- electric Ghost anyways the first time I saw it. Tomorrow I’ll sight in the PARD and get ready for the rats. I’ll be shooting the 25.4 JSB MRD’s from it, like I did with the Delta. AoA tests shots showed it averaging 966 FPS. Same as I had the Delta Wolf shooting.

I have a recurring event on my phone that reminds me to charge my battery

Nice gun but I'm curious on what kind of rats or more specifically how big are those rats you are shooting, sounds terrifying!

Which is why I simply love the Atomic/Ranger platform, fully kitted out under 7 lbs. And seriously capable sub 50 yards…
