  1. It's an excellent place to start Lee.

    You can confirm your Zero at 100 and then step out in 100 increments banging away at good size steel plates to dinky steel plates until you run out of ammo!

    Marc will help you if needed or other shooters (all a good bunch) and excuse me for being patronising if it comes over that way (just being helpful!!) I would suggest you print a ballistic calculator/solution for your ammo based on your known estimated velocities so that you can dial in for each distance. If you have a kestrel all good but if not suggest you print off a ballistic calculator for 5 10 & 15 mph winds so that you can get a reasonable guesstimate for dialling in windage for the different distances.

    They also ave full coffee and biscuits and toilet facilities (and that's in order of priority for me!) 😁

    It's also under cover as well.

    All the best

  2. I use a usb microscope bought off eBay/Amazon (circa £20) and some free software used for star gazing.

    I'm using a Windows tablet but the principle is the same.

    When I'm home I can confirm the details of the above.

    The bottom line is you don't have to spend a.fortune.

    Catch-22, now you tell me...... just discovered that Wet SS Tumbling will remove sharpie colour markings even in the extraction grove.   At least I now know that i will have to tumble the segment cases in their respect batches and then re-mark them.  I think I need one of these...

     

    I'd have one of those if it played that music while I was reloading! 😁

  4. I'm going to come over as very OCD, so no flaming please, it's just what I do that works for me......

    I wanted to batch my brass in batches of ten based on their WCC. Cleaning and processing in tens is completely crazy and unworkable so had to come up with a solution that would allow me to wet clean in ss media in batches of 50 and allow them to get sorted afterwards.

    I use an electric scribe/electric pencil to mark a number on the left of the headstamp for the series and a letter on the right size to group in 5/10.

    It's a chore and a bit extreme but that's my regime and helps me keep track of brass.

  5. Hi All,

    I read this article which is interesting. It explains the likelihood of why 2019 GGG 155gr ammo was causing broken extractors.

    https://nra.org.uk/ggg-2019-7-62-155gr-match-ammunition/

    Does anyone know what primers GGG actually use for this ammunition?  (just so that I can avoid this issue!!🙂 )

    As an aside, they state the ammo isn't dangerous, however, is it worth calling out that for anyone reloading this brass it may be worth noting that there could be a potential increased risk of premature case head separation? (not being a Negative Nelly but this may be worth calling out for anyone unsuspecting of once-fired brass).

  6. Hi M,

    If its a new factory rifle and hasn't been rebarreled / rechambered etc. it's unlikely that you would have excess headspace due to the quality control of the manufacturer. Obviously, exceptions can occur but if you're unsure you could get it checked by your local gunsmith to ensure its within tolerance.

    Cheers

  7. Hi M,

    First off what rifle are you shooting?

    If it's a standard factory rifle I would suggest you just bring your thermometer down a few notches.🙂

    Some rifles are chambered with a forgiving chamber and some are within really close tolerances such as high end match/target rifles. If you compared the two fired cases from each rifle there would likely to be a reasonable variance.

    As an example my Lee Enfield battle rifle SMLE circa 1916 is a .303 and when compared to my mates Lee Enfield No 4 T you would be amazed at the physical difference with the eye when comparing them.

    A grown up will come along soon to comment but rifles are chambered within an allowed variance/tolerance within SAAMI specs and that's why you see differences in cases between rifles.

    Don't sweat it too much. This game will have you chasing your tail for a long time! 

    All the best

    G (in Fife and it's dry. Bonus!)
