    Getting head around headspace

    Cheers Big Al I'm going to ignore the PPU and concentrate on the Lapua I've a batch of once fired that I'm reloading at the moment - thereafter I hope to see consistency on second firing It has been suggested elsewhere that with a combination of the elasticity (spring back) of the Lapua brass and the low pressures associated with 6.5 x 55 swede (estimated via 'Quickload' to be a peak pressure of 50470 psi) that the case is not expanding into the chamber fully. This might be rectified on 2nd or 3rd firing PS - I don't understand why I'm getting multiple entries of my comments

    Getting head around headspace

    I have measured the length of chamber using the hornady headspace kit - Headspace measured at 1.768 using a fired PPU case and insert C375 I then started the process of reloading using new Lapua 6.5 x 55 cases I was surprised to discover that my now once fired Lapua cases measured only 1.762 using the same C375 insert Even the same Lapua, now twice fired, is measuring at 1.72 to 1.764 I'm not knocking back the shoulders at all as I'm probably getting a head space of 1.768 minus 1.762 = .006 of an inch My questions are 1. Since we are measuring outside dimensions why might there be such a discrepancy between the PPU and the Lapua? 2. with a headspace of .005 to .008 am I risking over stretching the web and risking case head separation with my Lapua 3. Will the measurements of the Lapua settle down and conform to those originally measured (using PPU) with further firings 4. Despite taking great care with the reloading process I am getting a velocity spread of around 60 fps - might that variation be in part due to the slight differences in head space as not all the cases measure quite the same and I can't uniform them because I dare not bump the shoulder back even more?

    1st shot in a string velocity

    I think the barrel was OK 12 shots in all - not 14 - first one was deleted - it was 25** something Shots fired are as follow 2648 2640 2635 2645 2656 2669 2688 2669 2644 2670 2640 Sorry - ES was 53 with SD 16.8 Deleting the first 3 shots barely changes the SD - 16.3

    1st shot in a string velocity

    I've just completed my first ES test with a magneto 14 shots with a 200 ftper sec spread !!! First shot was the culprit at 150 ft/sec slower than the average (which was 2654) In good 'statistical fashion' I deleted the first cold bore shot (note SLOWER) and the ES dropped to 60 I'll do it all again shortly but was wondering whether there is an explanation (other than me) for the slower first shot

    Alternatives to QuickLoad

    I'm a recent user of quickload and now find it invaluable As I'm now playing with variables that hitherto I was not aware of - I've discovered that the fill weight (H2O) on my 6.5 x 55 Lapua is considerably less than that I've found suggested on internet, load manuals or QL Anyone else found this?

    Cz 452

    http://www.formriflestocks.co.uk/stocks Though apparently Edgar Bro have the monopoly on the provision of CZ stocks from Form However as Edgar Bro don't sell 452 anymore perhaps something can be done I'm in same boat as the 'butt end' of my 452 plastic stock is degrading rapidly

    Bushcraft Hunting Knife

    They are just words A knife suitable for bushcraft is also suitable for most hunting applications Usually vice versa - however a lot of hunting knives stray into the 'Rambo' world and those are a useful as a chocolate fireguard One caveat to the above - folding knives are generally not sufficiently robust for bushcraft use

    Best Wellies?

    Yup - I still buy aigles but in reality I should buy cheap and regular - broccoli to the ads and fake imagery I'm having a bit of a rant coz of general disappointments all over the board We - the practical folk - should listen to what we the people say - I for one enjoy your input on a variety of subjects Brown Dog
