    Need input bf I buy a millennium 2

    Re: Need input bf I buy a millennium 2 I use the IR screens frequently.. They work brilliantly at night in complete darkness (extra care when setting up in the dark.. ) And daytime too. My 100yrd testing strip is alongside tall trees, so I often get dappled sunlight above the chrono, which...

    Heading to the range with a ladder!

    Re: Heading to the range with a ladder! you've got it right, chrono numbers are nice, but not hugely important at this stage. They would give you an idea if you had a particular target velocity you wanted to reach.. If your chargeweights are going up but your velocity stays about the...

    What determines barrel life?

    Re: What determines barrel life? A simple test you can do at home, Eat LARGE plate of hot curry, wait approx 1hr, Sit on toilet and push like hell. Measure burn rate. Repeat test with SMALL plate of hot curry, Compare burn times. (Do NOT try for 3000fps for purposes of this test) this...

    What Bullet For 7-08

    Re: What Bullet For 7-08 Still early days for me.. Only x80 rounds down the barrel, including x20 factory 140grn federal fusion I used to zero scope and break the barrel in. (The fusion ammo grouped 1.5" at BEST during breaking-in etc) As soon as I got on my 162 amax/h4350 test loads the...

    What Bullet For 7-08

    Re: What Bullet For 7-08 Front plate removal is easy, just carefully drill out the two rivets and slide the front plate out. To take fully advantage of the extra mag room, you may have to use a dremmel (or something similar) to remove the overhanging lip of the feed ramp on the action...

    Full Length Sizing Questions

    Re: Full Length Sizing Questions If its a standard FL die your using (NOT a bushing die) then keep the expander in and use the die just like you have been doing. A standard FL die sizes the necks down a little undersize, then as the expander pulls back out it 'expands' the neck to the...

    Full Length Sizing Questions

    Re: Full Length Sizing Questions Punter... Don't panic. Did you get a measurement of the new brass BEFORE you loaded it up first time? upon firing, they will have grown a little.. Just not completely. there are plenty of threads around here explaining how to setup a FL die, but basically...
