.22 Creedmoor Load Information from Peterson Cartridge
Peterson Cartridge Company (“Peterson”) has released a lengthy, authoritative guide to the 22 Creedmoor cartridge, a popular wildcat based on the 6.5 Creedmoor or 6mm Creedmoor necked down to .224 caliber. We think the 22 Creedmoor would be a great long-range varmint cartridge, similar to the .22-250 Rem, but with a more moder, efficient cartridge design. In addition, some PRS/NRL competitors may turn to the 22 Creedmoor because it has less recoil and is flatter-shooting than the 6mm Creedmoor. In addition, .224-caliber match bullets are typically less expensive than heavier 6mm and 6.5mm projectiles. Less recoil, and less cost — what’s not to like?*

Along with load data, this article has specific sections dedicated to: Primers, Rifling Twist Rates, and Reloading Supplies. If you are considering building a .22 Creedmoor, we recommend you download the full Peterson .22 Creedmoor article, which is available in PDF format.
Peterson states, “Since its inception in 2007… the 6.5 Creedmoor has seen some pretty meteoric growth in popularity. That growth continues as of this writing, as the cartridge has now gone mainstream with hunters and shooters alike. As the popularity of the 6.5 Creedmoor has increased, so has the number of wildcat cartridges based off of it. Some of those popular wildcat cartridges are the 6mm Creedmoor, the .25 Creedmoor, and now the .22 Creedmoor. This data sheet will cover the .22 Creedmoor.
To help our customers, and anyone else who shoots .22 Creedmoor, we decided to create this Data Sheet and distribute it. [In this LOAD DATA Document] you will find four (4) common bullets, and four (4) common rifle powders used when handloading the .22 Creedmoor cartridge. We then took the different bullet and powder combinations and loaded them up to the SAAMI Maximum Average Pressure (MAP) for the 6.5 Creedmoor and 6mm Creedmoor cartridges, which is 62,000 PSI. [O]ur goal was to provide a wide spectrum of bullet weights and the powders used with them.
All of the following data was gathered by our ballistician in our indoor ballistics lab located in our factory in Pennsylvania. Although we were able to gather pressure and velocity data in our lab, we have NOT tested these loads for accuracy. Again, these loads are just designed to give shooters information regarding what velocity, a given bullet and powder charge combination, will produce the SAAMI Maximum Average Pressure (MAP) of 62,000 psi.”
Sample .22 Creedmoor LOAD DATA
IMPORTANT — Pressures can vary significantly with different Cartridge Overall Lengths (COAL). In addition, ANY change to ANY load components — primers, bullets, brass, powder — can affect pressure. Always load conservatively. In addition, because of variances in bore dimensions, some barrels may show higher pressures than others. Again, always start with conservative loads, well below MAX pressures.
*Actually there IS a potential downside — reduced barrel life. We expect that a .22 Creedmoor running hot varmint loads would experience shorter useful barrel life compared to a 6.5 Creedmoor. This is based on what we’ve observed with .22-250 and .22-250 Ackley barrels compared to our 6.5 CM barrels.

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!
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.
22 br 80 gr. sierra 3150 fps.
From the cartridge guide,

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.
Ok perfect Now 7mm wsm please.
Federal 210 and 215 series are large rifle primers, 205 is their small rifle primer. So this casing takes larger rifle primers.
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.
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.
Speaking as an ex-first class machinist. Peterson cartridges are beautifully machined.
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.
