really flat nose slugs?

[jhalcott]

just how accurate or good would a cylinder of lead/lead alloy be? I saw a mold for casting cores for jacketed bullets and thought that their ARE flat ended bullets for 38's why not for RIFLES?? It would be simply a 100 per cent meplat slug with the front end a bore rider cylinder. just thinking almost out loud again!

My experience with "flat nosed slugs" have been limited to revolvers and pistols. Real wadcutters out of a handgun start seriously losing accuracy after fifty yards. Frank Siefer and I "designed" the Lee 310 gr .44 magnum bullet and it has a meplat that is .350" wide. It works extremely well to at least 100 yards. I have not shot it farther than that, so cannot truthfully speak about whether it continues to be an accuracy bullet past 100 yards. It is the most accurate that we have ever shot out of several .44 magnums up to 100 yards.

FWIW

Core molds cast a slug that is very undersized and designed to be used in a swageing die whether with a jacket or without. I seriously doubt that you could get one to shoot well as cast.

The Lyman 311440 is about as much of a flatnose rifle design as you'll find that works well to at least 100 yards. Search the archives in Group Buys for the 311440 , it's about 6 pages back. A core mould has no lube grooves, I see much brushing in your future should you try it.

I've used standard 38 wadcutters, both solid and hollow base, in my 35 Whelen. Wicked small game boolits, but the accuracy tends to head south after 50-75 yards. Solids held up better for me. IIRC at 100 yards I had groups about 6 inches and some tumbling or at least heavy yaw was evident.

[jhalcott]

yes I realize what the "core mold does. I was just thinking "again"! I gather accuracy would be terrible then I was NOT thinking of shooting a core,rather a bullet that had a grease groove or two and a FLAT point.If a small to medium meplat is good why can't a full one be better,YOU know bigger is almost always better!

[44man]

Some totally flat points do not engage the forcing cone or lead right. A little taper on the nose helps center the boolit. The larger the meplat the more it will drop at range too. My WLN drops 4" at 100 yd's and my WFN drops 6", with a 50 yd setting. Both are equally accurate.

Then you want a 311440 type design. Take a look at that thread I mentioned or 45 2.1's avatar.

..........A fully flat nosed rifle boolit, such as the cores (below)

Would probably be a comparatively short ranged proposition as others have suggested, but hell on wheels when it hit something. IIRC for some years the NYPD issue ammo for their M10 S&W 38 Specials were 160gr WC's. Maximum impact effect and limited penetration to protect bystanders.

Issues in a rifle would be problematic feeding and as 44man suggested, possible alignment issues. The Lyman 311440 is VERY FN'd for a rifle slug, but it has a bit of a engraving surface to aid alignment in the leade.

Any FN slug has the ballistics of a brick so is shedding velocity at a rapid rate. I've used the Lee C309-113F (the F is for flat) or 'Soup Can' against ground squirrels and there is no doubt in my mind of their 100% effectiveness, and only starting at 1450 fps too.

Hey Dale53....thank you! That Lee 310 grain .44 boolit is amazingly accurate and shoots well in all four of my .44 magnums.

I'm also casting the Lee 320 gr. .45 boolit which is a very close copy of your design.
