I had smaller balls () - around 450 - bought from a nice stand at Bisley many many years ago (for a Colt I used to own) & they were and absolute b*stard to get in - almost had blood dripping from your fingers when you had loaded six.

Mentioned this to my local man (specialist lead caster who even supplies Fultons) - who requested to see said balls........he pointed out that they were too hard - threw them all into his 'Rifle Bullet' melting pot & handed me a bag of his 457s FOC.

Yes - these are a 'firm' push - but they leave a nice fine ring behind

I have since bought a Lee 2 gang & 'roll my own' when the weather is warm - over winter I buy from my man (see www.tfsa/co.uk ) Allwood Stocks & Mouldings

Maybe you have hard jobbies too - if you know what I mean ?

Regards

Roy
