7br aka Mark B.
On the internet, I am 6ft tall, good looking and can dance.
As in all things Mechanical, it is easy to make assumptions and assertions..My serious Question
Who has Tested the Results of Various Methods, especially against your bestest most roundest Boolits...On Target... Bench/Measuring devices be damned!!! 1/2 inch on target??? or a Foot on target??
Inquiring minds require (non Biased) quantification... Thanks
If you have actually used Beagle's technique and were disapppointed, then go ahead and poo-poo it. I used it on Lee 452-250-RF with the desired result after running through a .454" size die. The alloy was old style wheel weights with a bit of added tin. The finished bullets were Round and .454". I have since changed to powder coating and sizing.
prs
You are saying that the non taped dimension was under .454 inch and actually increased in size on the trip through the sizer die?

Beagling actually does work. You may not get match-quality boolits but beagling them up and sizing back down you can fit them (close enough) to an odd-sized bore, or you can determine what size mold you actually need.
Anyone who doesn't believe it, take it up with "Beagle" if he's still around or browse his threads, here's a place to start: https://castboolits.gunloads.com/sho...ghlight=Beagle

It absolutely can. An out-of-round piece of lead being pushed through a cylindrical die can displace in more than one direction; it doesn't just make the lube grooves smaller. Most of the sizing would occur at the fattest portion but as that metal is smashed inwards it can force the undersized portion out somewhat.

Important to note , that a Lubri-sizer does Not operate like an Edger in a Sawmill...No material is "shaved off...or shouldn't be if operated and set up correctly.. A proper die qmay Try to force metal longitudinally...but a Proper Punch fit will control that, not allowing "flash" either..
Look to Swaging to fully Understand!!!

The current edition on news stands ( January 2023) of guns magazine has a full article about beagleing bullet molds starting on pg. 54. The author Alan Garbers used the technique for a Winchester 1886 in .40–82. Shooting steal targets at 150-200 yards. He beagled a Rcbs mold. Bullets were droping .002-.003 undersized. The author states he was able to makes is boolits 003-.004 larger by beagleing. Than sized them in a Lee sizer
The author even gives a shout out and mentions the cast bullet forum where he found the technique.
Disclaimer: I’ve never done but, probably will have to in the near future. Yeah I’ll admit For bench rest shooting it may not be the best technique. However, for banging steel and making ammo for not so common guns it would definitely be a viable technique.

Don't knock it, if you haven't tried it. I have to confess I was sceptical at first, but I needed some larger .361 boolits for one of those 380/200 Aussie trade-ins. I salvaged a 6 inch piece of aluminum flashing that was supposedly .003 and put in my 358-311 and it worked very well. Groups shrank, leading ceased, and accuracy improved.
Now maybe for the most demanding of applications, where extreme accuracy is required, it might be a little problematic, but for iron-sighted revolvers, it works very well. The accuracy gain from properly fitting boolits far outweighs the minor loss of accuracy from a slightly unbalanced boolit.
Now, for it to work, you have to do it right. First, .003-.005 is about the limit that you can achieve, it works best with a single layer. If you spread the mold halves too wide, you'll get flashing and whiskers. That can also be an issue with a pot of alloy that is too hot. Second, you have to size the boolit for best results before launching through your six slightly different chamber throats (unless Doug Guy has done his magic). You'll get better accuracy that way.
However, it can and does yield very serviceable boolits. I have not tried it in rifle cartridges, but der Beagle has published photos of his experiments which seemed to show success. This is a useful trick for the caster whose wallet doesn't bulge with Benjamins.

rintinglen (above) is correct: It works, is fairly easy to accomplish, and can be reversed if one doesn't like the results. E.g., I had a Saeco RG-4 bore riding CB [mould] which dropped CB's too small for my .30-06 (Win. Mod. 70). Once I beagled it, I got a CB whose nose actually was engraved by the rifling with a corresponding increase in accuracy. The only downside was those CB's looked ugly, at least to me. I think I swapped or sold it for something that actually fit my rifles's bore.
Btw, I did this to a Lee 6 cavity mould as well and it worked as expected.

I hope after all these posts, everyone is convinced that beagling works. Many thanks to Ukrifleman, who first told me about it for my 6.5 Swedish boolits.
I too was mildly skeptical, but could also see it working.
I wouldn’t do it for shooting bench rest cast bullet competition, but for typical usage, it’s great!
I’ve got two uses for it.
1. Many Lee dies are under size. It’s a quick, easy way to make an undersized bullet usable. I bought a Lee .312”-185gr 2R RN for my .303Brit and 7.62x54R Mosin-Nagant 91/30.
The mold as received was just a mismarked .309”180gr RNGC. I was very disappointed!
I taped it on both sides! It now throws bullets measuring.315”. I size them to .314” and they shoot great. 20gr of #2400 in the Brit. And 24.0gr in the Russian.
I did likewise with the 160gr .311 PTD GC 6-cavity. Sizing to .311 doesn’t affect the accuracy any observable amount.
Another use is to enlarge the .356”, .401”, and .452” Lee TUMBLE LUBE MOLDS that typically cast undersized bullets. I recently used a .356” 124gr RN TL mold that I’d given up on 25yrs ago. I taped it and powder coated the bullets. They measure .359-.360” now. I sized them to .357” and they shot marvelous loaded over 5.4gr of LongShot.
I've done it too, and will add to the "It works" chorus here. I was surprised at how well it works.
I don't use Beagled molds anymore, since I started powder coating. Powder coating has been an absolute revolution in casting, for me. I tend to be a bit of a traditionalist, but powder coating just solves so many problems, including undersized molds.
I've beagled molds in the past, and it works. I prefer high temp flue tape over the aluminum duct tape.
In case it has not been said - for those who do not know our very own Beagle, on this board, was the perpetrator, hence the name of the procedure. Thanks again, Beagle!
However, PC seems to offer an advantage in both sizing and a hard coating for many applications. End all of improvements? Probably not, but it works for applications where needed.
In one case recently I got a mold of smaller dimension of its larger kin, specifically to PC and eliminate the nose size problem of the bigger brother. Worked better, actually great. Ready to load and shoot dimension was ideal for it's application.
It ain't rocket science, it's boolit science.
