    Not quite as happy as Victor Meldrew, in Bakewell, Derbyshire.

  1. Rifle Cleaning

    Soak a patch with KG1. Push through rifle. Repeat. Use a nylon brush with KG1 and brush the bore full length a dozen times. Leave for 30 minutes. Patch out until patch comes out clean. Use a soaked patch to clean the muzzle. Repeat process with copper remover if you wish to remove copper. works for me.
  2. Satterlee load development method

    Does EPVAT testing include reloaded cases?
  3. Satterlee load development method

    36.6gn was the load I opted for as its sits between the closest two loads of 36.5 and 36.7 and therefore allows for a little load variation. As I had opportunity I shot it at 300 and 500yds and it performed well. I will re chrony the 36.6gn load and check it for accuracy at 100yds shortly.

    Dan, I think you inbox is full, been trying to pm you and it won't.
  5. Satterlee load development method

    Yes, that's pretty much it. This method specifically looks for several charge weights that produce similar velocity therefore low S/D and E/S. and load to the middle of that charge weight spread. The aim being to produce a load that performs well at extended range, specifically 600yd plus. Once the load is found it can supposedly be tuned by seating depth, I haven't done that as all 14 of the chrony'd rounds had a poi of less than an inch at 100yds and the rounds with the velocity plateau grouped smaller than the overall group at a similar poi test to OCW. I jumped straight to longer ranges and it seems to be accurate. I will test it in the tunnel though and see how it is and at longer range when I get opportunity.
  6. At last a perfect afternoon for varminting

    Yes beautiful rifle and stock, wrong handed mind but lovely none the less. Nice day for shooting.

    Update. Our local club had a range day today so the ideal opportunity to see how the load performed. Thankfully the forecast torrential rain held off with only a light shower mid morning with a wind value of 0.5mil at 300yds which later died down to .2/.3 after lunch at 500yds. 10 shots at 300yds produced 10 V bulls, 10 at 500yds produced 9 V bulls and 1 bull which i'm pretty sure was a bad wind call on my part as it was slightly right of centre at 3 o'clock. Vertical elevation was very good and as adjusted elevations perfect for the velocity. Overall I'm very pleased with the results and plan on trying the same process again for 155TMK's in 0.308 but might reduce the initial test down to single loaded rounds as a trial and use sorted cases.
  8. Satterlee load development method

    I thought the idea of this method was to firstly reduce the amount of ammunition and hence components used to identify a stable velocity node and secondly to identify a charge weight variation where the velocity remained constant and therefore allow for case capacity variation and charge weight accuracy ? I'd agree re good case prep for accuracy but was hoping to avoid weighing cases and such like if possible. The cases I used we prepped using my usual routine and not weighed. There is obvious variation on some charge weights but had interpreted them as the equivalent of the scatter node in a OCW test, is that incorrect?

    Dan, thanks, interesting to hear others results. Cienfuegos, thanks for the graph it really helps identify the plateau.
  10. Have a look at 3M product range.
  11. Intrigued by the 6.5 Guys interview with Scott Satterlee and in need of developing a load for a 6.5x47 I thought I'd give it a try. The goal is to develop a good stalking load, I already use 129SST's in a 6.5x55 so I decided to try those as I already have some. Previously fired cases were cleaned, annealed, resized and trimmed. Varget was chosen for the powder as I have some left to use up and 14 cases were charged and bullets seated to give a 0.020" jump. Charge weights were 35.7 to 36.9 and two cases were loaded at each increment. This deviates from the Satterlee method as I believe he only loads one round at each increment but I wanted to see what deviation I got at each point. The loads were than shot using a Magnetospeed chrony and the results recorded. Here are the results: 35.7 2790 2759 35.9 2785 2783 36.1 2774 2801 36.3 2812 2807 36.5 2824 2829 36.7 2832 2831 36.9 2852 2832 There is a velocity plateau between 36.5 and 36.7 so the next stage is to load five rounds at 36.6 as the middle of the node and see what SD they will give. Has anyone else tried this method and how did it work for you?
  12. Fill your profile in please as per section rules. thanks.

    Have you input your actual case capacity in to QL?
  14. Sam, please complete your profile as per section rules. Thanks.
  15. 308 dies neck size only

    Personally I wouldn't bother with the neck sizing only route as sooner or later you are going to need to bump the shoulder back any way. From personal experience Forster FL dies are excellent. I use them in 4 different calibres and when set correctly they produce cases with minimal run out on the neck - typical 0.001 or less. I use Forster micrometer competition seater dies and they produce loaded rounds to the same run out. Yes the brass is worked more in the neck area but I anneal anyway so its a moot point.
