Hi I'm new here but not to guns. I worked as a manual machinists for 18 years before moving to an off grid island in British Columbia with my Wife and 3 kids for an interesting job for a few years, quite the life style change but I do still have a lathe here and can still do some work.

here are a few projects of mine that I have put together over the last few years. I still own all of them posted. I build these projects for a hobby and I love big bore rifles.

first off is my 43 express (11.35x62) rifle. (to make the brass you take any 375HH family case and trim it to 62mm and run it through a 43 Mauser sizing die) its a large ring Mauser that accepts a small shank barrel, it has a 71/84 Mauser barrel on it. the barrel threads were 1.000" 12tpi and the receiver was .980" 12tpi so I just picked up the barrel threads on the lathe and cut them 0.010" deeper with a 55* tool. feed and functions great. holds 3 in the mag and 1 in the chamber. I just realized I don't have pics of this rifle completed. ill take some new one here soon. its nothing special but it looks better then just the barreled action. it shoots a 365gr .447" cast bullet at 1925 fps for 3000 ft-lb of energy at the muzzle

second is my 460 Weatherby, this was a simple build. I basically bought a Zastava M70 in 458 winmag, ordered a reamer form PTG 460 Weatherby reamer with .750" free bore, took the barrel off the rifle rechambered it and then made a new mag box for it and went to work on the feed rails, it feeds and functions fine but I can'T use the 95mm OAL unless I single feed them (base of it into the mag and the bullet on the feed ramp) so instead I use a 92mm OAL and they fit and function in the mag just fine. so I use the 480gr woodleigh bullets that call for an OAL of 92mm. its very light its 8 pounds 6 oz. (loaded is 8 pounds 12oz) since the pics I have blued the barrel and added open sights to it. also I realized I don have any pics of the mag or feed lips or anything. ill get more.

my newest project is my 500 Jeffery build on a P14 action. as of right now I just need to solder the sights on and blue the barrel. I used a new 32" 50BMG rifle barrel that was miss chambered and sold as a "gun smith special" for real cheap. and I bought a reamer from PTG, chambered and threaded the barrel then made the feed rails act like a single stack mag lips. its awkward for reloading but it functions perfectly and holds 2 rounds in mag 1 in the chamber. it weights 10 pounds loaded with 3 rounds. I went with an 18.5" barrel. 6" long knox at 33mm diameter then 6" of 2 degree taper then 6" of straight 27mm diameter. (muzzle is 27mm diameter) the riles OAL is 39"

first video you can see I still fumble it while loading it but by the 3rd its getting better, still a pain in the ass to load but at least it feeds well. 2nd video shows bolt not closing on the 3rd round in the mag, if I extended the mag about a 1/16" it would hold 3+1. I may do that later on.

and lastly its not a project but i figure we all like pics. its just a win m70 in 375HH. i fire a 300gr bullet at 2450fps for my heavy load.
