Starline produced 300 HAM’R cases are available, but cases can be made from common and available 5.56/.223 cases.
Any AR15 platform rifle can be converted to 300 HAM’R with a simple barrel change and the use of 300 Blackout magazines. 300 HAM’R has 18% more retained velocity, 40% more energy and a 56% flatter trajectory than the 300 BLACKOUT at 200 yards! 300 HAM’R was designed around a slow twist, 1-15 twist match grade barrel optimized for accuracy with 110gr to 135gr bullets. The 300 HAM’R has a 300 FPS velocity and 400 FP energy advantage over the 300 BLACKOUT at the muzzle.
The 300 HAM’R is capable of duplicating the proven ballistics of the legendary .30-30 Winchester from a comparable barrel length. Only 25-28 grains of powder compared to the 34-38 grains the .30-30 requires, so recoil is reduced.

Protect Receiver From Damage When Clamping
Heavy-duty blocks allow you to firmly clamp AR-15/M16 receiver halves in a vise without risk of crushing, twisting, or otherwise distorting them when applying vise pressure or torquing the barrel nut. Keeps your rifle secure for safe, effective cleaning, assembly, and repair. High pressure, solvent resistant, structural Rynite block and insert surround the entire upper receiver and support it inside and out to make rebarreling the AR-15/M16 an easy, one-man job. Lets you firmly secure a mil-spec carry handle receiver or mil-spec flattop receiver in a large bench vise for barrel removal/installation. Torque generated while tightening the barrel nut is transmitted to the block and insert, not the receiver. Minimizes the possibility of damage to the barrel detent pin and receiver detent notch. Holds securely without marring the finish.
DO NOT USE ON BILLET UPPERS OR LEFT HAND UPPERS, OR DAMAGE TO THE UPPER CAN RESULT.
