LEE bullets or Lyman for my ROA

[Erwan]

Well, I'm talkin about my ROA the best pistol that it was ever made but........................... I've small problem with mine, not really important but annoying, enought pour moi in this time.
Since 1976 I'm shooting with round balls or rond nose. For the round balls no probleme but with the rond nose I've two case: shooting with Lyman bullets 452-389 or other LEE 456-220 1R.
The Lyman bullets 452-389 works fine but are difficult to insert right in the chambers of the cylinder but they are very accurate at 50yds with only 21gn of swiss black powder N°2.
The LEE bullets are far easyer to insert but they doesn't wok so good (in terms of accurracy I mean) at the same distance and that whatever the powder charge...
In your opinion what is wrong: LEE bullets 456-220 or something other... ?

If somebody have an idea about that I'll take it, with great pleasure

I'm sorry but my language isn't better that the last time I did post here...

My ROA seems to do equally well with everything I've fed it so far (ball and about 8 different bullets). But then I've only been shooting at 15 yds where the differences aren't as major.

No idea why the Lee isn't doing so well. If the Lyman's are more accurate I'd go with those. But what's more difficult about loading them?

I like a very wide meplat on my bullets as they are for hunting and that design creates the best wound channel if expansion doesn't happen. I went with custom designed molds and will creating a new one that weighs around 230-245 grns. I'm not familiar with the Lyman mold you listed but if you are shooting paper only a SWC style is still preferable cutting clean holes.

What a few guys do is resize the base of a standard bullet. In our case it would need to be .454" as the chambers run .453".

I cast .452- 255 gr. RF bullets for mine. https://www.grafs.com/retail/catalog/product/productId/7789

I have to roll a file over them to fit the cylinder chambers tightly but they are accurate at 35 yards in my gun. If I cast with a bit of antimony in with the lead, they are about the right size but harder.

What charge do you use for those? I'm curious about the OAL of that bullet. Who makes it?

the 1R means it has a rebated base (heel) to help it load easier which helps it load straighter in the chamber. which one would expect it to be a bit more accurate ( not necessarily true)
You want the base to be a shade undersized as to chamber diameter on these bullets.
I have a custom mould for my Remingtons, where the base is .440 the next band is .452 and the upper is .455 works fine in all my Colts and Remingtons and did in my ROA till I had it converted to 50 cal need to make up some round balls for that

I cast it from the Lee mold given in the link. It's the standard .45 Colt type bullet but with a flat meplat.
I shoot it with 30 grs. of 3F black powder or with 21 grs. of BH209 with Doak's modified nipples using Rem. 7 1/2 primers.
