I see alot of folks trying to get a 70+ grain bullets in a .223/22-250. when you could jump to another caliber and just shoot the "low end" of that round,........"as fast as u could push them" ,AND still hit something was the "motto" was it not? :banghead:

Because people want to shoot a heavier bullet. They deflect wind better, and have far better BC values than lighter bullets. Why shoot 160 bullets in a 6.5, why shoot 220 grain bullets in a 30-06? Why shoot a light bullet fast? Why a 40 in a 224, why a 100 in a 30-06? What difference does it make? I like blue cars, others like red. No ryhme or reason. We're just people trying to do something different.

I think what he's saying is that people are trying to hot-rod cartridges instead of buying a larger gun. For example, trying to obtain .243 ballistics from a .223 or .22-250 with heavy-for-caliber bullets instead of just buying a .243 and shooting light-for-caliber bullets.

Oh I see. My bad.

It's because a 70 grain expanding type bullet in a 224 caliber is basically meant for "big" game. (no not moose, perhaps small deer and antelope) whereas the light bullets of the same weight in a 243 is a varmint bullet meant for exploding small animals that are of little food value.

Let me re-explain it. A 120 grain bullet for a 25-06 is a legit deer slug, a 120 grain 30-06 bullet is no deer bullet. But, many want to shoot varmints with their 30-06, and many want to shoot deer with their 25-06.

And the winner is:
Because people want to shoot a heavier bullet. They deflect wind better, and have far better BC values than lighter bullets.

Heavy .224" bullets were developed for long range match competition.
As noted, they handle the wind at long range & maintain speed further, way better then a light-for-caliber bullet of larger diameter.

people are trying to hot-rod cartridges They sure are. The AR 15 shooters are dumping powder and watching the fps on the Chronograph. All they want to do is match or exceed factory velocity. The heavy bullets only make it worse. IMO.

There's something to be said for getting the best performance for your application, but as the saying goes, A man's got to know his [cartridge's] limitations.

There no use trying to make a .308 shoot like a .300WM, but on the other hand, as technology and knowledge improves, we can build new loads that outperform old loads.

get a 70+ grain bullets in a .223/22-250. when you could jump to another caliber
Since you said "caliber" and not "cartridge", the answer is because a 70gr .223 bullet will have a higher BC value than a 70gr 6mm or 6.5mm bullet.

77gr SMK (or similar) at 200/300 yards and 80gr SMK (or similar) at 600 yards seems to be the norm for High Power Service Rifle shooters (.223) ... at least that's the case at our club. IIRC, the AMU uses the same bullets too.

A box of 50 70gr .224 bullets is cheaper than a new gun. Add the cost brass, dies, powder, and bullets and it gets even steeper.

People are constantly trying to do more with less.

Now if I could just get the bullets guys to build me a 140 grain BT in 25 caliber, my 25/06 would be a fine 1000 yard gun! Just think what the BC would be on a 140 BT... .600 maybe.

the 250-3000 ,is what all the heavy bullet user's should have bought in the 1st place..:)

It's also like when people try to hod rod their little honda civics, and tow enormous trailers with a pickup truck. There are faster cars, and there are trucks better suited to the job. But what the heck, why not use what you got?
