Hoping someone can advise on recommended start and stop loads for the above Neither Hornady nor RS 62 web pages give any recommendations I've nicked the numbers for 140 gn sierras and Quickload isn't getting upset with my suggested loads However .... Someone on here might have some empirical observations to offer?

mine is 600mm deep by 2000mm long by 40mm thick with a 400mm dog leg holding the press I could have a bench the length of the M1 and still be in a mess 1000mm doable but obviously more the better

Tried to PM you but apparently you can't take messages

Yes please Tony John

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

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?

Second thoughts

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

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

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?

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
