I already have 1200 shots through my barrel, but have shot hBN coated bullets from day one, so I hope to get around 1800 shots out of this barrel. I get 3650fps out of my 28″ barrel with the 75gr ELD-M, but next barrel will be a 24″ fluted one to be lighter and easier to handle.

Speaking as an ex-first class machinist. Peterson cartridges are beautifully machined.

22 Creedmoor may not be useful for PRS since velocity is limited at a maximum of 3200 fps, and most guys using 6mm are using heavier bullets and still getting around 3050-3100 fps. The 105-115 gr bullets they favor make it easier to see their impacts at long range.

I have a 220 Weatherby Rocket that feeds through an AI magazine.

Think 3600fps with 75 grainers. I’m using this downtime to get some more loads together and will run it in a match.

Federal 210 and 215 series are large rifle primers, 205 is their small rifle primer. So this casing takes larger rifle primers.

It will be a barrel burner, much like running 80gr bullets in my fast twist 22/250.

All that is old is new again, the 220 Swift still outruns it with most all bullet weights with ease.

So just a .22-250 AI with small primer pocket brass.
“Creedmoor” brand makes a huge difference. Course it will go further, faster, more accurate than another case of the same capacity.

I noted that they used large rifle magnum primers and was totally amazed! [That case has a capacity of approximately 51.5 gr of water (per Ammo Guide)]. Their PDF (link in the article) discusses their decision to go LRM. Even more amazing, they basically ignored the almost doubling of ES and SD for an increase of .728 percent (7/10ths of one percent) in MV. Why in the world would you accept an almost doubling of ES and SD for 25 fps? Reloading 101 – failed!
