Doug, I checked my mold with a dial caliper and came up with 0.241"; If you have a load you'd recommend for a Marlin micro groove barrel with this bullet I'd like to hear from you.

...................If you guys have come up with 340 Lee's that cast large enough to use in 45 cal rifles, you MUST be living right :-). Over the years I've bought 3 of'em and every ding bling one of'em won't drop a slug over .457". They ARE good for this:

Makes a great heavy slug for the 45 Colt, but that's not really why I'd bought 3 over the years!

Buckshot, I Have The Same Problem With The Mold I Have. I Finally Bumped Some Up To .460" So They'd Work In The Marlin; But They Won't Shoot As Cast Worth A Flip.

My Lee 457340F shoots quite well in my Marlin (early new issue 1895) with an appropriate charge of 4198. I regularly get 1.5" five shot groups at 100 yards. My Marlin has conventional rifling. I have never checked the barrel dimensions as it works so well.

Of course, the first thing that I did was have a decent recoil pad installed. that original curved plastic butt plate with the "razor" edges about ruined me during my first trial (I was wearing only a white tee shirt on my upper body). I had obvious abraisons with serious bruising. However, a good recoil pad totally solved that problem.

Strong action .45/70's have recoil to contend with if you load them up to the "serious" level. Of course, since I don't have any "Lions, tigers and bears" around here (biggest game is whitetail deer) I really don't need any velocities that exceed the old black powder ballistics.

Regarding the undersize bullet moulds - I wonder why swage dies are not more popular. Most of us have a strong single stage reloading press (mine is a Rock Chucker) and a good swage die in that or even a dedicated swaging press like RCE ( http://rceco.com/MN.asp?pg=default ) builfds, together with a swage die set, used in conjunction with a slightly undersize cast and lubricated bullet should really solve the bullet size problem. Of course, the problem is that the set up for just one bullet would cost about $400.00. Subsequent bullet forming dies would be about $100 per set. I rather suspect that is a real "put off" for most of us.

Our beloved Group Buy moulds sure solve most of those problems, don't they?

FWIW

.............The Lee 458-405HP casts (my mould) about .462" so that one as far as light Lee 45 cal moulds go would work. I hate to suggest their 405 plain base mould as like the 340gr one, I've never had one that dropped a slug over .457". I also have the Lee 457-450F and the 500gr models and they do cast large enough to be useable.

However if you don't just HAVE to have a Lee, then for a plain based slug Lyman makes a couple that are fine performers. Personally I like the RCBS 300 and 405 boolits the best, but they're both GC designs. Don't know if you're set up for them or not.
