The first four opened new levels of chambering precision in factory rifles and are optimized for high BC bullets. The last two greatly broadened the horizons of America's favorite rifle.

The only ones on your list that have made a huge difference are the Creedmoor and maybe the Blackout.

For decades, the gun industry had a "big 6" group of cartridges that were virtually required chamberings when introducing a new rifle the 243 Winchester, 308 Winchester, 270 Winchester, 30 06, 7mm Remington Magnum and 300 Winchester Magnum. The 6.5 Creedmoor is the first cartridge to challenge this list in decades.

The Blackout is important due to its military applications which is always a good thing for success.

The PRC cartridges are still a small niche and will remainthat way, possibly going the way of the short magnums in a few years. They'll still be around but limited availability in factory rifles.


Would you say the 6.5cm is better than the tried and true 6.5x55 in the hands of a reloader ?

No.

It's not better than the 260 Remington either.

But it has made a difference in that manufacturers now consider it a must have chambering in their rifles.


Because of marketing has it made a difference correct ?
Im not saying these newer cartridges are not good and I do own a few of them but when it comes down to performance they dont do anything more than the older cartridges can be made to do

When I need expert advice I tend to talk to myself
The older I get the better I used to be
