    Scope ring selection/opinion

    Well your thread is asking for opinions . . . .you've got several suggesting vertical splits rings are less than ideal. . . .and now your unhappy. Just wait for those that agree vertical split rings are superior to comment and it will be all ok.

    Scope ring selection/opinion

    Yep bin vertical split rings. Your never going to get consistent tension on both the scope and the rail and are prone to failure. The reason it originally had a single ring is so only one thing needs to be in alignment. If you want to run 2 rings, especially that close together, I would lap...

    Hardening tungsten?

    Thanks for the education guys and in particular Jo for the link. Looking at pure tungsten vs steel vs tungsten carbide I think I'll stick with what I have for now!

    Hardening tungsten?

    I'm in the process of designing a fixture which uses a piece of 3.2mm tungsten rod approx 150mm long as a stylis to follow a contour. I chose to use tungsten looking for something with a small diameter that would give me minimal flex over the 150mm length. What I got was 3.2mm. 0.3%...

    Take my hat off for the Aussies.

    Yes they were originally made in Adelaide SA by sportco that were later bought out by omark who I think we're actually Canadian company? You might want to have a look at what they are running for at the moment. I bought my first beaten up one about 15yrs ago and it was $150 and they seem to...

    Take my hat off for the Aussies.

    They shoot better than they should but not exactly something to preach about. Single shot only. 3 lug, full diameter bolt with floating bolt head held in place with a pin. Actions are mild steel so bolt lugs engage into the back of the barrel extension. Pros. Seems to be accurate due to...

    Colchester Student !800

    https://www.machineryhouse.com.au/d5212 Like this. Note this one is only 5 micron (X2 for diameter use) but I think they also do a 1 micron if you wanted

    It's a PITA . . . . To get it neat you need a small scale.

    What's a good insert for dry turning 304 stainless?

    I like these. On a manual machine I do a fair percentage of stainless and find them good for pretty much everything else as well. A good multi purpose insert.

    Metric drill set types questions

    Waaaaattttt? A 10mm bolt is 10mm major diameter. Just like a 1" bolt is 1" Somewhat difference is metric can be simple. 10mm bolt has a 1.5mm pitch so you use a 8.5mm tapping drill. Etc etc etc Metric is just like imperial but uses decimals instead of fractions.

    Metric drill set types questions

    Standard set would be 1 to 13mm in .5mm increments. I have a couple nice sets of Dorma drills that are .1mm increments up to 10mm.

    7mm cartridge choices

    Usually just use 6.5x284 lapua brass and neck it up. 1000s of f class shooters are using it every weekend. Lapua have also released straight .284 brass but so far it's in limited quantities. Probably not the ideal SHTF setup but plenty obtainable

    7mm cartridge choices

    I was going to mention the SAUM but brass is getting harder to find and not sure if it's going to be around forever. I find it strange that Lapua won't make SAUM or WSM brass but has started making 6.5PRC and 300PRC all non belted magnum cases.
