So, are other FL dies compatible with the Lee kit, or am I completely off tangent? I suspect I should really try and get to see someone doing a full reloading cycle to fully understand the process (I have read the pinned reloading thrwad on here and seen a few YouTube videos, but I know nothing beats a 1-on-1 explanation).
Having a chance to observe an experienced reloader would be a great advantage for you.
I bought the Lee Breech Lock Anniversary Kit and have been using the Lee dies, press, press-mounted primer feed, Lee trimmer and the powder thrower for the last few years.
As far as I know the dies, threads and presses are interchangeable from different manufacturers. I haven't had to change the Lee dies but have added a Lee de-capping, a Lee Flaring and a Hornady cam lock bullet puller and invested in a few of the locking breech lock collars.
I have acquired bits from other manufacturers as others have stated above...just my niggles are quite different to Cottis'.
I think the Lee dies are fine and have worked well. I have no idea what sort of group improvement would be made by side-grading to RCBS or Forster.
With my shooting from a standard weight stalking barrel, the Lee ones have produced ammunition which has averaged 0.846" over 37no. 5-shot groups of 130grain TTSX and averaged 0.609" over 9no. 5-shot groups with 110grain TTSX both in .308. I am sure my shooting skills have a much more deleterious effect on group size than the die manufacturer.
The Lee scales I didn't get on with at all...I found it really difficult to hook the powder pan on and off without disturbing the balance arm and consequently had to keep repositioning it...I ended up using a lovely set of air-damped Oertling Laboratory scales which you can buy on eBay for £40 or £50 and have the pleasure of a Mahogany and glass cabinet housing a beautiful brass scientific instrument to look at while being far more precise than any dedicated reloading scale. Each division on my Oertling scale equals 0.2mg which equals 0.003grain so it will respond and easily show whether you are adding a large, medium or small powder kernel!
The Lee Chamfer tool I didn't get on with so bought a Case Prep Multi-Tool and a Flash Hole Uniforming Tool, both by Lyman
A Redding powder trickler and a Frankford Arsenal kinetic hammer were added along with an Ultra Sonic cleaner.
