I recently purchased an Underwood carbine and brought it to the range this past week. I was lucky to find a box of Magtech 110 gr FMJ ammo and and a box of Winchester 110 hollow soft point ammo. I first fired about 15 rounds of the Magtech FMJ ammo and was pleasantly surprised at the accuracy at 50 yards. However, when I began shooting the Wnchester hollow soft point ammo, my shots were all over the place, with one round missing the paper completely. Has anyone else had this experience with Winchester ammo? What ammo do you recommend for deer?? The barrel is an Underwood 1943 as well as an Underwood receiver. The barrel is in great shape as is the rest of the firearm. Thanks for your help
Due to the gas port in the barrel, leading gas pressure to the piston that powers the extraction and subsequent chambering of the following round, I believe most would advise avoiding unjacketed or exposed-lead bullets in the.30 Carbine.
Some carbines run well with lead bullets IF the velocity is kept down to the 1600 fps area. Some people claim they can drive lead bullets as fast as FMJ rounds but what they may not see is the lead building up in the expansion chamber for the piston. Other carbines do not shoot lead at all as they are all over the target.
