Hybrid......II

Post by Bob Mc Alice »

Last August I put my Ruger 77 7x57 into retirement. I wore out the factory barrel at 4600 rounds since when I bought it new in 1995. I put a 3-9x Leupold on it to have as an extra hunting rifle and put it in the back of the safe.

I dont like owning guns that I cant shoot alot. I got to thinking about the successfull M70 project a couple of weeks ago. I did not want to spend alot of money on a new match barrel. A year ago I bought a new Remington 700 24" satin finish 7-08 barrel off Guns America for $40.00. It was a warrenty replacement, not a takeoff, that ended up for sale. You just cant go wrong for this price. I put it away for a rainy day.

As we dont get much rain in these parts, I did not think too hard about doing this conversion. Out came the Ruger and four to five hours later I have another 7-08 mouth to feed.

The machining needed was near identical to the M70 job. Both the M70 and the M77 have similar breech area dimensions. I had to make a 4140 spacer ring, blasted and blued to match the barrel. Again , no effort was made to index for the barrel marking. This time it came out in a good spot. Only some minor wood work needed for a float condition.

The M77 is a well made , high quality push feed Mauser derivative made from an investment casting (lost wax process). From there it is precision machined to final dimensions. Being a .30-06 action length made no difference on how well it feeds and extracts the shorter medium cases. It functions fine.

I took the Leupold 12X off my Rem. 788 .308 for now till I see if it is a shooter. I may take it out tommorrow for a test run.


Kevin......#7....you got some catching up to do.

I was able to resize part of my supply of WW 7x57 brass to 7-08. This is a process that alot of people use to reform brass to a desired cartridge from a similar parent case. I got 100 cut on my lunch half hour, will get to the other 300 as needed.

My neighbor - a retired engineer - was building a compost bin this weekend. Talk about using a sledge hammer to swat a fly...

Bear, in the past for similar large cut off projects, I have used hardened file type trim dies only using a band saw instead of a file. I also have used a miniture tubing cutter over a mandrel turning the case by hand or in a drill. This is way too much to be removed by an ordinary bench top case trimmer, even the power driven type will make lots of chips.

The lathe is a wonderful tool.

Hey, if I had a lathe or mill and the skills to use it there would be endless projects! I'm more than a little envious.

Kitty and I have discussed getting one for the kitty Cave, but then we'd never get rid of Bob...
