I've been fooling around for several years trying to find the most accurate projectile for my 41 Mag. An 8 1/2 inch barreled S&W Model 57. I tried various jacketed and cast. The cast boolits I've tried were my own and store-bought. The store-bought cast were out shooting my cast and jacketed. For handgun hunting I use factory ammo, Winchester Silver Tips in particular. For practice and paper punching I wanted to cast my own and be as accurate as jacketed or store-bought cast.

I discovered it yesterday!! A Lyman 41027, a hollow based, button nosed, wadcutter. I originally got the mold a few years ago and had dismal results with it. I was just about ready to sell it when somebody on this site or another suggested using softer lead and a milder powder charge.
My previous attempts were cast from 100% clip-ons with a tad of tin.

I can say up front the hollow based wadcutters are a pain in the rear to cast. The production rate is slower than cold molasses, the rejects are many and a casting session will really test one's patience. After following suggestions from more experienced casters I reduced the powder charge, using 4 1/2 - 5.0 grs of Bullseye. I cast from a batch of apx 80% stickies. The remaining 20% that was left in the bottom of my pot was a mixture of clip-ons, pure and a touch of tin. I don't have a hardness tester but fingernail wise the castings felt as soft as pure lead. Whomever it was that advised me to use a torch on the pin, thanks!! I still had plenty of rejects but heating up the pin really helped.

I tried 50/50, Jake's Red and Lee tumble lubes. I loaded some without sizing and tumble lubed. Pan lubed, filling the bottom two grooves with NRA 50/50. All the grooves filled with Jake's Red with my RCBS sizer and a heater. I used a .410 sizing die on the hard lube and some of the castings with the 50/50. The remainder of the pan lubed with 50/50 and apx 50% of the tumble lubed were sized with a Lee push through sizer. As far as the sizing and lube I couldn't see any difference on paper. The few that were pan lubed and all the grooves filled smoked excessively. In the future I will likely shoot them as cast and use tumble lube. The hard lubed and sized boolits did not shoot any better than the tumble lube. The only advantage I could see with the hard lube is it smoked less.

I was really surprised how accurate they shot. I honestly didn't think I could shoot that well. Not a load or boolit I'd rely on or prefer for self defense or hunting but for punching paper it is the most accurate I've put through my Model 57.

Good morning Thanks for that info...
I would be intersted to know what your group size is with this combo... ??? I have a S&W 57 and am always tinkering with my 41īs looking for that Best of the Best.
I have looked at that mold sevral times and always said... NOPE not me.. No more hollow base molds. Turn up the temp on the mix... HIGH & HIGHER
I think it is far easier to drill a hollow base after casting. A drill press and a simple metal block guide and any 41 boolit can be hollow pointed... Production rate sure is better. And the Aggrivation factor greatly reduced. But I generally just stick with flat base and thump the steel chicken.

I didn't measure it but it was the tightest group I've shot with a handgun in years.

As I mentioned, casting HBWC's will really test one's patience and the reject rate is very high. A drill press sounds like a good idea. I also have a HBWC mold for 38. It doesn't shoot any better than my Lee TL 148 WC. I will have to try the 38 hollow mold with softer lead. For years everything I cast was water dropped from clip-on wheel weights.

Don't know what happened in my previous several attempts at editing my prior response.

A drill press sounds like a good idea. Please let me know how it turns out. Don't know if it would be any quicker in the long run but after my experience with hollow based moulds I don't want to be casting them when I'm with in an ear shot of woman and children. The reward of launching a super accurate boolit is very gratifying but casting them turns the reloading hobby into a dirty job.

Friend of mine, unlike me, has a very patient personality. He casts .450 hollow based conical balls intended for a 44 Remington cap and ball revolver, loads and shoots them in 45 Auto Rim and ACP. He gets remarkable accuracy shooting them. He such a good shot though it is almost embarrassing shooting next to him. I tried shooting hollow based in my 45's and didn't see any improvement compared to my plain or gas checked based 45's. I might not be able to out shoot him but surely I can out cast him!!

We did a group buy on six cavity button nose plain base WCs for the .41 Mag a while back. If there is an accuracy difference from the Lyman 41027, it's going to take a better shot than I am to demonstrate it, even from an old Lee machine rest.

As to defense capabilities, if I encounter any trouble that can't be resolved by 220 grain .41 cal WCs at 900 fps, I'm gonna run, and me old and fat.
