I said "those guns were designed FOR A PRESSURE CURVE LIKE YOU WOULD GET WITH 4895 AND 150 GR. BULLETS."Where did you get the only for reloaders stuff?The original surplus 4895 powder marketed by Hodgdon after WW2 was what was used to load M-1 Garand and Browning 30 caliber machinegun ammo.When they load 30/06 ammo at the factory it is loaded with a pressure curve that will safely operate semi auto rifles.Because they don't know what it will be fired in.In the seventies winchester loaded factory ammo in 30/06 that worked great in bolt actions but when fired in rem 742 's the extractor tore the rim because the pressure was to high at the gas port,the operating rod opened the bolt before the pressure dropped enough in the case for it to be extracted.Wrong pressure curve. Winchester blamed the Rem.742 Remington blamed the winchester ammo.This was in several magazines at the time.Winchester quietly changed their 30/06 reciepe.I knew people that had this problem,cases stuck in the chamber sometimes,most of the time the case came out but with the case ruined as far reloading it because the rim was damaged. the American Rifleman had an article about bending the operating rod on M-1 Garands using 4350 and 4831.After seeing an operating rod on a Garand and 742 you would wonder how the rod on the M-1 could be bent since it isso much biggerthan the one on a 742.The guy I worked for did Remington warranty work,I think there was a factory service bulleten about slow burning powders in 740's and 742's.Hornady ligt mag ammo says on the box that is for bolt actions only,not semi-auto's.Pressure curve again.Speer reloading books have a section in the step by stepinstructionsand in the troubleshooting sectionon reloading semi auto's.For a 742 to operate like it's suposed too,you need a pressure curve like that produced by 4895 and 150gr. bullets,not nessesaarily with 4895 and 150 gr. bullets but like that.
