I have a 300 BO, but it's a howa. I'll keep it.
getting a ruger predator wouldn't be too hard I think.
I have stepped into this caliber for my AR15 Hog Hunting Rig (upgrading from 300BO), and as we speak I am actually loading up some 125gr TNT for it. I wrote a post on this caliber a couple of months back to see what others were thinking.... Grendel Forum is for purists
What I have learned after reading all posts on the 76 page thread about the 300HAM'R on the Texas Hunting Forum is as follows... Bill Wilson has going out of his way to get this cartridge properly launched with industry support. Sig Sauer requested SAAMI certification for the 300 HAM'R, which was granted in Jan 2020 right before Covid Panic/Pandemic turned the firearm industry upside down. Unlike the early years of the Grendel, there is no trademark fiasco so appears that industry participants are more actively participating from the onset.

Everything you want/need for the 300HAM'R is available through Wilson Combat, and it is priced extremely reasonable...no Pandemic premium or Firearm Panic markup. I was pleasantly surprised by this!

Barrrels:
Prefit (AR15) - at the moment Wilson Combat "WC" is the primary source of barrels ($200-$280). https://shopwilsoncombat.com/300-HAMR-Ba...ucts/1072/
Prefit (Bolt) - WC has a kit for the Ruger Ranch. https://shopwilsoncombat.com/CONVERSION-...-300HRACK/
Based on thread, WC spun up a couple of barrels for the Howa Mini, but that didn't pass muster, because of the mag release's tendency to spit out magazine while being carried.
Shaw is also making custom barrels. https://www.shawcustombarrels.com/news/n...arrels/244
Reamer
It is a SAAMI cartridge so any reamer maker. Also, PGT has one in stock.
4DReamerRental has reamer for rent. https://4drentals.com/product/300-hamr/
Handloading - Load Data

Brass:
Sig is producing cases (nickel & brass). I just bought Sig nickel cases from WC for $38/100 cases. https://shopwilsoncombat.com/Reloading-C...ducts/470/
Starline is producing brass cases ($78/250 cases) https://www.starlinebrass.com/300-hamr-brass/ and you can also buy from WC site.
or Make your own brass by converting any .223/5.56 cases... just like making 300BO.
Bullets:
As far as projectiles the 300HAM'R has about 30 different popular bullets ranging from 95gr to 150gr. For the most part these are commonly found bullets used for .308. In addition, Speer and Lehigh Defense have been tailoring some of their bullets to optimize in the 300 HAM'R.
Dies:
RCBS 300 HAM'R Dies
Lee Precision 300 HAM'R Dies
Case Gage and Bullet Seating Gage by WC that mirrors chamber reamer.
Ammunitions:
WC has become a mini-ammo plant for the 300 HAM'R. You can buy directly from them (use link and then scroll down WC page). https://shopwilsoncombat.com/300-HAMR-Am...ucts/1070/
Note: WC offers a variety of ammo with selection of different weight/styles of bullets for 300 HAM'R. Supply/availability of the WC ammunition is dependent on their ability to source bullets from the bullet manufacturers, with availability differing by specific bullets. Same issue throughout the industry.
Sig Sauer is also set to manufacture ammo...hence, they are making brass cases for the 300HAM"R and requested SAAMI certification of the cartridge.
