    Small Rifle Primers ?

    Thank you. This is very interesting but focuses on .308 Win Palma Brass. The tests appear to indicate that CCI BR4 produces better groups, lower ES and lower SD than CCI 450 Magnum Primers but I also found a post by Laurie saying he keeps the BR4s for exclusive use in his 308 and they are too powerful for 6mm. With the 6.5CM falling between the too, perhaps leaning slightly more towards the .308 (?) does that mean BR4s could be used / recommended ? It certainly appears that getting the right primer makes a difference in SRP brass. So much to learn !
  2. Hi, I’m picking up some Lapua Small RIfle Primer brass for a new 6.5 Creedmoor build and wondered what Primer you’d recommend ? I was thinking CCI 450 Small RIfle Magnum Primers - are they a sensible choice ? Thanks

    Couldn't resist.

    Back in my day an aspirational watch had a calculator on it ?

    Brass shrinkage!

  5. PRS is great with that. I shot a match with this trooper last year. He kicked my butt !

    Can I ask how day 2 runs vs day 1 ie is the second day a repeat for the same 10 stages run on the first day or are there differences ? Thx
  7. Optimally, it needs to be done in the transonic / subsonic range. What distance that is will depend on what bullet, velocity, density altitude etc that you are using/shooting in.

    In general that’s true. However, both mid and high end loads can affect throat erosion. What matters more is how aggressive you are in putting them down the barrel. If you are allowing the barrel to cool between shots then it’s much less of an issue than if you fire a rapid string of shots so it depends on what you do as much as the powder you choose.
  9. It’s expensive for what it is imho. Don’t get me wrong, it does what you want it to do but I’ve gone back to the Harris with a podlock and spiked feet. For me, it’s faster to deploy and locks up tighter than the Atlas which loosens itself. Admittedly, it’s not as cool looking. https://www.sportingservices.co.uk/collections/sporting-services/products/podlock-for-the-harris-s-swivel-head-bipod There is a good thread here you might like to read: https://forum.snipershide.com/threads/who-has-gone-back-to-a-harris.6897655/
  10. Unless you really need one right now, I’d be tempted to wait. The US military put out a tender for a new bipod design and none of the existing models on the market met the standard so you are about to see a glut of new designs and models coming through over the next few months in spec with the tender. I think some might even have exhibited at the Precision Rifle Expo last week but I hear they are a vast improvement over what options are out there at the moment. Personally, I run the Atlas PRS. It’s ok but I wouldn’t buy it again.

    My DIY annealing machine!

    Me too for .308 /.260 / 6.5CM thx
  13. Don’t think so. Def no crunch on bullet seating and I load them pretty long ie over 2.90” OAL. I was just testing a couple of loads and will be backing down. Thx
