Hi, I'm a cherry smokeless muzzleloader, and I recently got an SMI 45 Cal barreled muzzleloader on my H&R rifle. I apologize if this was covered already in another thread, but I did not see it. Has anyone ever used knurled up full bore cast bullets in a smokeless muzzleloader? I have IMR-4198 powder, and I will be using 250 gr full bore cast LFN bullets to see how they perform.' I'll be using a wad between the powder and bullet. If anyone has load data for this type of bullet, I would appreciate it. I'm planning on shooting out to at least 200 meters. Any advice is appreciated, or load data, or even if just to tell me that I'm an idiot for thinking about this.

Do you have a Douglas barrel on that frame?

Unless you use reduced loads, smokeless will probably be too fast for lead bullets, except in a sabot.

I would be worried about barrel leading. If I remember correctly in my TC Contenders it got really bad once I got above 1500 FPS. Gas checks help stop gas cutting but I thought they did nothing to stop leading.

So you think using maybe Blackhorn 209 powder will be better to attempt to shoot it this way?

I have that same rig done by SMI. I get good results with all bullets in the 275gr range such as the Barnes XPB 275gr. Annealed they slide down the barrel with no sizing and have been good on paper out to 200, I'll be sighting in out to 300yd as soon as the weather cools down which is about the max range. Been using 59gr of I4198 with a wad, but I'm using Direct Ignition. With a 209 ASG style plug 64gr of I4198 was giving same results in the high 2500 fps. 275be's, 275 Fury's are a good choice as well. I've used those with same powder weight and had good results. If you haven't already, I would have the breech plug it came with drilled and tapped for a tungsten bushing and set screw. Those goofy vent liners that come with it are next to worthless. Steve |

With proper alloy and lube speeds up to 2200 or 2300 are pretty easy to handle and do. Over 2300 to the limit of about 2600 with lead alloy is doable but requires much experience and the proper fit. Paper patching of lead alloy bullets was predecessor to copper jackets and is doable and easy to learn and you can shoot up to the 2400 speed OK. Soft lead is limited to about 1900 max even with paper patching and anything over 1700 will lead with only lube used. I suggest you hop over to "cast boolits" and see there is much to learn about shooting cast bullets. castboolits.gunloads.com/forum.phpI shoot cast in sabots. Works great and is plenty less cost to get good trigger time. Accurate Molds has lot of bullets specifically designed for use in sabots. The cast bullets do not have the high BC for really long range but they are plenty effective for hunting at modest range. Good casting and "Beware of The Tinsel Fairy"!! 10 |

Sabotless 250gr cast out to 200 meters sounds like a horrible combination. There are tons of good heavier conicals that will get you to around 200 meters with only about 1400fps MV or less. Even in a 1-30 you can more than likely still shoot something around 400gr. 80gr by volume of BH209 will launch a 400gr at over 1400fps.
Dan at Bullshop can cast them in anything from dead soft upto a 30-1 alloy. Plus lubed and sized to your needs. You will want them sized to around .015-.020 over land size for BH209. Thats with soft lead. Never tried a alloy harder than about 8-10BHN.
What twist did you get? If its a 1-36 you are gunna be limited how long of a bullet you can shoot. The old Lymann 457122 330gr "Gould" bullet should work. Cast in soft lead its about 350gr. They shoot great in my Super DISC with just 70gr by volume.

I tried sabotless cast lead in my McSavage but Could not get it to stop leading with various alloys from dead soft to LYMAN #2. I didn't load it down below 2400 fps with a 270 gr bullet as that would have defeated the purpose of building the gun. From my 45-70 days I seem to remember 1800 fps works with a medium hard alloy.
