FEDERAL BRINGS OUT NEW CARTRIDGE

20 January 2025, 22:17

Quick double check confirms, air resistance (drag) slows the bullet with a force proportional to the square of the velocity. Basically for every little increase in velocity you get a lot more drag. Also the concept of bullet velocity as being so important came from a time of poor BC bullets and no practical ability to adjust for environmental conditions and range estimation. You needed a flatter shooting rifle to compensate for errors. Now a 180 grain 7mm Berger with a G7 BC of .340 at 2800 fps has plenty of energy to kill a bull elk beyond 600+ yards plus rangefinders and ballistic compensation eliminate the need for speed. This new cartridge was designed to titillate gun influencers and their followers. Not hunters.

Another 30 super carry unless I miss my guess.

Those thin jacketed bullets are not the answer to killing.

Federal should concentrate on making smokeless powders much less expensive. Then, offer LR
primers at 1999 prices.

I think I will retain my pre-64 Winchester Model 70s
in 270 WCF. They utilize .277 bullets.

Long range rifle hunters wound and lose elk/deer almost as much as some bow hunters. (get as close as possible, then get 10 feet closer...)

I believe air resistance will increase with the cube of the speed. That's the way it works for automobiles.

I resent the negative remark concerning us curmudgeons.

Okay, here we go again. Hard to find primers, certain powders and many calibers of brass. Most companies say they are at capacity to help alleviate the problemm. So, how to alleviate the shortage problem? Invent a new cartridge, and use hard to get supplies to produce that new cartridge. Amazing how companies always manage to be able to produce enough powder and primers to launch a new cartridge. As for an 80,000 psi cartridge, I will defer to the late, great Jeff Cooper when he said, and I am paraphrasing here, "An ingenious solution to a non-existent problem."
