Physics...I love a good Newtonian physics thread! Later we'll get into string theory and quantum mechanics!

KE is a controversial issue; many here, including bullet makers, are not too keen on it. See similar threads below. Like it or not, the law of physics is there to be appreciated, not ignored.



"My" unwritten rule is 1000 FT-LBS for antelope/deer-size game and 1500 FT-LBS for elk-size game and higher than the minimum recommended bullet velocity (a critical choice) to expand at POI effectively. It has not failed me for many decades. The NUT (who is responsible for bullet choice, shot placement, etc.) behind the trigger remains the most significant factor.

This, what he said:)!

Feenix, you are right, they shouldn't be ignored, but it is a good idea to understand what factors are important in the equation.

If I understand correctly as per my #74 post, the 900 FT-LBS at 100Y is the minimum requirement - .22 caliber (assuming centerfire). So .223 Remington factory ammo from Berger meet NE's threshold.

correct as bad as it seems it is legal.
Worst part is the people shooting a 223 around here are usually 10 year olds that cant hit anything and have a rifle with to long of stock and haven't shot more than 20 rounds in there life.
 
Funny thing is, where I'm from there are a ton load of youth and new hunters (for deer/lope) that are shooting 223's and 22/250's extremely well! Quite the contrary to your experience.

Sort out the stock thing, a good trigger and hearing protection and one can turn a youth with a 223 into a shooting machine in no freaking time!

If their gun don't fit, or they're not wearing muffs and such that's on the teacher not the student!
 
They even get a special season so they dont get cold.
I think more teachers are hunting than students though from what Ive seen and heard but they are having fun outdoors at least and spending time together

It's a regional thing! memtb
 
22 caliber centerfire of various cartridges, some as small as 22 Hornet gets used a lot in Texas and a lot of deer and pigs are killed with them.

Also, I'm hesitant to post because of some of the whack a doodle stuff that gets posted there but there's a compelling thread on Rokslide showing a lot of animals, up to elk, moose & bear with a .223 lots of photographic evidence showing some impressive wound channels.

I wouldn't use it for those applications but it further debunks the mythical 1000/1500# necessity for killing medium/big game.

Advancements in bullet construction paired with velocity have made a difference in terminal performance.
