Re: Homemade Picitinny Rail 7075 is stronger and more durable than 6061 so I chose it for the rail, and I just happened to have it in the right size. 6061 was all I had laying around for the jig, and it will do the job fine. Mac

Re: Tacticool .22 Build **pic heavy** Nice one mate I hadent seen this one of yours before, top job mate. Mac

Re: Homemade Picitinny Rail One of the slowest processes is getting the radius on the bottom to match if you dont have a cutter that exact shape. There are quicker methods of cutting the angles at that time that was the only tooling I had, so I made do with that as I couldnt afford anything...

Re: Homemade Picitinny Rail I know of the clearance you speak of, I checked it against all the rings I had both for weaver rails and 1913 Rails those included rings made by S&B, Leupold, Nightforce and Warne which covers anything I will be putting the rifle. So I left it at that, I was also...

Re: Project 375 ST I prefer the characteristics of the snipetac and the aggressive look of the ST round Vs the Cheytac, and it can drive that little bit harder. I can shoot cheytac through it as I do to fire form the brass, Its not worth the risk with the deer not with that bloke, any of my...

Re: Project 375 ST As a nice tease I took some pics looking down range off my parents lawn that would cream a few stalkers pants, pitty that I couldn't pull the trigger, not in my place just over our boundary, I took some through the bushnell rangefinders as well, please excuse picture...

Re: Project 375 ST G'day Sierra, I wish, work has me on a 1 hour notice to move at the moment, for the current hourly postponed Exercise and possible disaster relief due to the wild weather up this way. I dont want to get it half done then have to do the urgent bolt. Mac

Re: Project 375 ST I took the 350 grain preditors up to 3400fps this arvo with 139 grains 2225, pressure started to show a little high, I backed it off to 137 grains at 3225fps and shot a 6 round group at 300 yards around 1 3/4" centre to centre. Not to bad could be better though conditions...

Re: Project 375 ST The next day I put a few downrange at 300 yards with my fire forming loads of 132 grains of 2225 behind a 300 grain sierra (SGK) I ran them all over the chrony, velocities were consistant with all 9 shots falling between 3129 FPS and 3109 FPS only a 20 FPS variation. After...

Re: Project 375 ST Well after a few fire forming shots I Pulled two cases apart that did not go off in the 375, which I first thought had DUD primers that did not go off. However when I tipped the powder out( dug out actually) there was a fair amout of burnt powder in the two cases, the...

Re: Project 375 ST I then fitted the muzzle break and Its now a little disappointing to shoot . It has really tamed it down and reduced most of the recoil. It no longer drives you back a foot whilst trying to put the scope through your safety glasses. The first two shots I put into a tree at...

Re: Project 375 ST Fired the first shots out of it over Xmas. Just fire forming a few cases so I can work on a load with the 350 grain preditors. My fire forming load was 132 grains of 2225 behind the Sierra 300 grain game kings. It has a rather nice recoil ( my opinion ) No one else liked...

Re: Project 375 ST There's not much room for massaging the weight down, the price you pay for having a 5kg barrel scope is another 1 kg, add bases rings and a muzzle break and it's 8 kg without a stock. I could have run a smaller slimmer barrel, no one likes small things, plus it would...

Re: Project 375 ST Here is the picitinny rail and the ARD after I cerakoted them the other day, the other ARD is for vman Here is another pices of plate about to be cut for the rear of the stock Mac

Re: Project 375 ST Heres a few pics of the custom ARD or Anti Reflection Devices I make for various rifle scopes. . Mac

Re: Homemade Picitinny Rail I then cut the radius on the bottom of the rail base, note the change in depth of cut due to the taper. after the raduis was cut I removed the rail from the jig turned it over and drilled and counter bored the screw holes I used the protractor to set the rail to...

Re: Homemade Picitinny Rail I then drilled and tapped 6mm caps head bolts x 4 through the side of the clamp. Then when I want to put a custom taper on the base all I need to do is raise one end of the jig in the vice to match the angle on my universal protractor. Using a Formula Sine A =...
