The rifles chambered in the 6 Creed are twisted way better then the million .243 rifles out there

Loads are still 100 grains. With the VLD bullets being 103 to 110.the twist is not a cartridge issue. You can build a 243 Win with the twist to stabilize a 110 grain bullet. I feel to see a great advantage of a 110 grain bullet over 100.

Twist is not the cartridge as I am learning with the 35 Whelen.

300 PRC???
I just read about it in the Rifleman.
I know that Hornady needs to invent new stuff. I wholeheartedly endorse Capitalism. I have no issue with the concept of new developments.
Just my prognosis on it though.

Those who developed this approach to throat design also theorize that due to the fact that a normally seated bullet in a 300 Win.Mag. case can actually get a side thrust under ignition due to the fact that seating depth puts bullet shank past the shoulder junction allowing powder to lay up beside the bullet prior to ignition, this combined with the .315 over .308 throat to bullet tolerance.
One other tolerance hindering the 300 Win.Mag. is the shoulder of brass to shoulder of chamber dimension.
Since the 300 Win.Mag. headspaces on it's belt this means a tolerance must be established at the shoulder of the case. The simplest way to get that needed tolerance so it will function is to make the chamber longer than the brass at the shoulder, establishing yet another tolerance.
The 300 PRC is a refinement that eliminates all of the short comings of the 300 Win. Mag.
Almost the same can be achieved with the 300 Win.Mag mk 248 mod.1 as it too uses much of the same throat design that went into the 300 PRC. However the mod.1's short coming again is belted headspacing and case shoulder vs chamber tolerance, nice try but automatically obsolete.
My reply to this thread focuses on how the 300 Win.Mag competes with the 300 PRC from a technical perspective.
The 300 PRC is designed to increase the hit percentage at long range, 1000 + yards. The closer range to the target the higher the hit percentage, simple right?
Eliminate tolerance road blocks, increase precision, increase accuracy statistically. Unite this with truly amazing high quality cut rifled barrel, stock and modern easily corrected optics that track a range finder correct ballistic data and botta boom you're in the long range game, not the old school Grampys burned out 300 Win.Mag. fried throat but still shoots 2 moa good to go game.

I have never seen a dumb cartridge. I have seen many new offerings the last fifty years since I have been hunting, many good ones and some that died a quick death and some a slow death. They will live or die on their own strength. The newer powders bring on some interesting stuff, be ready for more to come. Many a good cartridge started as an experimental wildcat, just have a good time shopping for what fits you or yours. I never shot a .270 but when the WSM version came along I tried one and let my grandsons shoot it and now we hunt Deer with four WSM’s because it is all they wanted to hunt with. Good Shooting.

Nope not true; the 350 uses 9mm bullets. SAAMI spec calls for .358 minus .003; right within spec. The reason they did that is so they could use the massive 9mm bullet production machinery. And what makes us reloaders mad about it as all of us have stock piles of .357/8 bullets we want to use. If you load larger bullets, the chambers won't take them.
Its is widely used in my state which allows straight walls, and 99% of these deer hunters do not reload and do not care what it actually is.

So what we have is the 9 mm legendary blunder. They are advertising a 35 and what they’re giving us as a nine. Bait and switch!

I’ve ben playing with a .300 PRC and am impressed with the chamber & cartridge (completely unimpressed with the rifle, but that’s another story...) package that Hornady developed; as they did with the 6.5 Creedmoor and 6.5 PRC. Think forest, not trees with these cartridges.

Anyhow, a friend forwarded me this video and it reminded me of the premise of this!
