[QUOTE="Hugnot, post: 2535557, member: 115658"] Eons ago when I was not olde I shot NRA hipower with a long action. It was a M70 Win. The bolt stop bar on the extractor collar was removed & two steel strips were silver soldered inside of the magazine box at ..308 cartridge shoulder/body. No sheet metal spacer block in magazine. It worked just fine & the rifle fed beautiful rapid fire with 168 SiMK's from stripper clip. Bullets were loaded to boat tail brass end neck shoulder. Recently - I am shooting .22-.250's from a Ruger MKII SA's, designed for 2.8" more or less rounds. My .22-.250 rounds measure 2.65". Wonderful pleasing feeding - makes me happy to blaze away at certain targets. The Ruger .22-.250 magazine box has a sheet metal spacer, that magazine was replaced with a standard .308/.243 size. Generally a shorter round will work in a long action provided the bottom receiver rails or sheet steel magazine box top edges retain each round allowing it to be stripped from the magazine by the bolt so the bullet is guided into the chamber. Some receivers will accept different magazine boxes to allow rounds of different diameters or lengths. Feed lips of sheet metal magazines may be bent in or out & polished. Aluminum spacer blocks may be fastened inside magazines to position short or long rounds. The procedure is to fit the aluminum block inside the magazine box using a file. The aluminum block is then anchored inside the sheet steel box with small flat head metal screws thru holes drilled in box & aluminum block. The holes in the sheet steel box are counter sunk. When positioned & attached the outside of the box is filed smooth. For push feed rifles no ejector cut needs to be made in aluminum block. Check & adjust if neccessary for bolt clearance.

The rifle feeds beautiful & I often can take out 3-5 rodents sitting on the same mound. In this case the magazine was modified to accept rounds that were loaded .10 longer. [/QUOTE]
