GM Inland Carbine .30 Caliber

In General

My GM Inland surplus .30 Carbine circa 1943 sighting in on the 100 yard rifle range after it was bore sighted. I had a small four power scope mounted on it but removed it and went back to the iron sights because the scope mount would kick hot brass down on my shooting hand. Sighting in was done from the prone position using a Benchmaster Cadillac rifle rest. I decided not to show the target impact footage as it was mostly out of focus. I may do a follow up to this video at a later date to include target impact footage. This carbine is an old war horse that still is in reasonable shape for its age but I do expect it will need a shoeing from time to time meaning replacing aged parts. Understandably the accuracy is not as good as if shooting a new barrel and the fact of its age. It is a military autoloading standard issue carbine and military standard issue are not the most accurate weapons to begin with.

My failure to feed is a mag problem and is a common problem with mag fed guns. I had the feed problem with this mag using both the old ammo and new ammo. The ammo was factory ammo. I had that five round hunting mag sitting unused and unloaded for a long time and I should have expected weakening of the spring. I should have stored that mag loaded so the spring remained under tension. For now I am leaving it loaded to see if keeping it under tension will or will not improve the tension and feeding of the mag. If that fails then I may stretch the spring. Otherwise I may have to replace the mag spring or get a new mag. If the failure to feed happened to continue using different mags then the recoil spring of the carbine might need to be replaced. That is not the case here.

Thanks again for watching.
