Ya-know guys....................Wheels are still round.
I see no reason to re-invent them.

In the USA if you can lie to the buying public and tell them something is new and improved, they will often believe it's improved.

It really not.

It's just a reshape of a brass powder bottle behind a bullet.

Lazzeroin, Weatherby, A-square and about 10 wildcats have shown us this for 50 years or more.

Faster is not necessarily better, and in many cases it's worse.

Less barrel life, which means less ability to practice.

Higher cost of ammo which means less ability to practice.

Necessary use of high priced bullet if you hand load to withstand the higher impact velocities, which means less ability to practice.

Less availability or rifles in said caliber. Except for very expensive ones, which means most shooters will have less ability to practice.

Higher levels of recoil which means most shooters cannot shoot very long strings of fire, which means.....guess what? Less ability to practice.

Less ability to practice will mean a less proficient marksman in about 99.5% of the cases.

This is the "all American marketing ploy" which unfortunately works all to well.

Buy a new gidget and you'll have an advantage. But it's not true.

No one wants to tell the market the truth.

That truth is simple.

It's not the tool that makes the difference.
It's the shooter.

Practicing with your rifle is a far better way to make successful hunts then buying something new and (not) improved
