[QUOTE="Txhillbilly, post: 951433, member: 22844"] The 458 SOCOM is the way to go in a Big Bore AR. I've been shooting a RRA Mid-Length upper on a lower that I built for several years with no problems to speak of. I did need to cut a half-moon out of the front of the magazines,the bolt would push the nose of the last round downward when loading,and cut a big chunk out of the bullet. I usually shoot the 300 gr HP bullets for target's,and 300 gr Nosler Silvertips & 325 gr Hornady FTX's for my hunting loads. It also shoots the Remington 405 gr bullets really good. I use a regular AR-15 buffer spring,the heavier spring that came with the RRA 458 upper caused cycling problems,as it is too stiff. [/QUOTE]
