For 308 Winchester, SAAMI allows chamber headspace between 1.630″ to 1.640″, ammunition runs smaller. I tried three different brands of 1.630″ gauges and the bolt handle would not fully close on any. Headspace on the test rifle was set just below SAAMI minimum of 1.630″. The twist rates for the 6.5 Creedmoor and 308 Winchester are spot on in my opinion, but I probably would have run the 223 and 243 twists a little faster. Twist rate varies by caliber, the 308 shown here is a 1:10″, 223 Remington 1:9″, 243 Winchester 1:10″, and the 6.5 Creedmoor 1:8″. The hammer forged heavy barrel on the test rifle had a similar profile to a Remington Varmint contour, however, the shank was slightly thinner with a diameter of 1.180″. Either way, you would be hard pressed finding a factory precision rifle offering at this price point with this many features. You can look at this price one of two ways, as an inexpensive entry level precision rifle or, $1000 is a lot of money (and it is!). At the time of writing (February 2017), street price on this rifle is right around $1,000. The 1500 does have some key differences including a tang mounted bolt release, 2- stage trigger, 3-position safety, M-16 style extractor, primary extraction location and integral recoil lug.įor testing and evaluation of the HCR, Legacy International sent a 20″ 308 Winchester with a non threaded muzzle brake in black, model HCRL93122. Like most of Legacy International’s line, the HCR is available in a wide range of calibers (223 Remington, 243 Winchester, 6.5 Creedmoor and 308 Winchester) and barrel length configurations (20″, 24″ and 26″) with and without a threaded muzzle.Īs alluded to earlier, it is difficult to handle a Howa 1500 action and not immediately notice the similarities between it and the Remington 700 (similar action profile, bolt, lowered rear bridge and firing pin assembly). The Howa Chassis Rifle (HCR) is geared towards the precision rifle shooter by mating a heavy barreled 1500 action with an Accurate-Mag aluminum chassis and LUTH-AR MBA-3 stock. Howa rifles are currently being marketed in the USA by Legacy Sports International. Their action is known as the Model 1500 and shares some common features with the Remington M700. In addition to the Vanguard, they’ve also produced the Mark 5 action (for a period of time) and guns for Smith and Wesson and Mossberg. You might recognize their work in the Weatherby Vanguard line which they manufacture.
