Hi Dave,

I've got one of those - It's done me alright for .357 for the last couple of years, just to check the auto disk. However I've just recently got a different set for doing .303. The reason for upgrading was that I found the MTMs very inconsistant (probably due to me not taking more care), and got a variation of .2 regularly. They were very sensitive to any draft, movement or change, and because there was no form of 'dampening' they could read one thing one minute, and something different the next. They also really didn't like the cold.

Now I've got some RCBS 10-10s (stretched the budget a bit..), and find them very easy to use without faffing about (good dampening), and think they were well worth the money. :good:

Make a shield to stop air movement and put it on something very solid that does not move. Also make a test weight - a 5p is good, weigh it and write the weight on it and use it to confirm it still throws what it used to from time to time.
