Bullet size

[HW11]

I just got done fire lapping the barrel on my 44 spl to remove the thread choke. When I slug the barrel now I get a nice free tap through once I get the slug started. That slug checks .4295. I'm getting ready to order some cast bullets. So my question is, the muzzle is the tightest spot now and it is almost .430. Should I use a .431 bullet so it will have a good tight fit when it leaves the cylinder and starts its trip down the barrel or just go with .430??
Any thoughts on this would help.
Thanks

.431"O.D. projectiles have work perfectly in EVERY 44SPL sixgun I've ever loaded for, and that is a bunch.

Thanks
That's what I was thinking but I wanted a second opinion.

Spot-on...same for me.

.431 ... Have fun!

I would gauge the cylinder throats.

cadillo`s right , the slugs get "sized" by the throats upon firing , so if the bore slug will fall thru or push thru easily I`d say your intheboat at 431.

load a few to make sure there`s no chambering problems such as the front band hanging in the throats.

I have several .44's. I have one that requires .429", another that uses .430", one that uses .431", and a Bisley that requires .432" due to its large, but consistent from throat to throat sizing.

I have never slugged a revolver barrel, but do check all cylinder throats with a set of minus pin gauges. They will tell you what you need to know.

I would like to have a set of pin gauges but from the few times I have looked at them it looks like a set starts around 60 bucks for a set a 50. 46 of those I already know I don't need. I always just slug the cylinder but the gauges would be much easier.

I first bought a set in that price range, Chinese of course, from a big name tool company, but sent it back for a refund after I mic'd it and saw how far out of spec they were. I then got a really good set, but I believe that they came to about $250.00. I would never have dreamed how much I would use the things. Now I couldn't live without them.

You can find some quality used sets on craigslist at great prices or you can just get someone in your town to pin the cylinders for you...generally won't charge and you save the money spent on tools that are seldom used.

If you do much gun work, they are used quite a bit. I keep them right at my work bench.

I'm going to get a set, its only money and I can't take any of it with me. My son said he would rather have a lot of stuff than money when I die anyway.
