lee slugs

Boolit Mold Join DateJan 2013Posts6

I am trying to work up a load for lee 1oz slugs that I cast from stick-on ww and when I weigh them after casting they don't even weigh 7/8 of an ounce. they weigh 360 grains on my rcbs scale which converts to less than 7/8oz. am I doing something wrong? also I am using RIO 2 3/4 pre primed hulls and mec78t4
wads (they are a replacement for WAA12L) with 20 grains of green dot. the loads all crimp good using a star crimp (I do not have a roll crimp tool) I have only loaded 3 shells to see what they looked like and haven't shot them yet. I am doing more searching to make sure the load will be safe and the slug weight has me worried.

My Lee 1 ounce slugs are actually coming out at a couple of grains (insignificant) over one ounce using clip ons. Their overall length is .635+/-". If yours are significantly shorter, then I'd say someone put a 7/8ths mold in a 1 ounce mold box. Diameter wise, mine come out at .679 to .682"

You may want to check the accuracy of the scale with a known weight.

I just checked the Alliant Reloading Guide, and while they didn't list the Rio hull, I'd imagine its close enough to the Fiocchi straight hull that for all practical purposes the data should interchange. It doesn't look like you could get hurt with the combo you're loading if your scale checks out. With 1 ounce of fine shot it is supposed to be around 7,900 psi. A slug will make less pressure, and a lighter slug less still. Worst case, it won't make enough pressure and will make that BLOOP sound instead of a BANG.

Wildlew,

Do not let guys like Pipehand drive you away. This site is full of helpful people.

If PH knew the answer, he would post a reference. I am with you. The only way I can see a slug giving less pressure is if the slug/wad are a loose fit in the bore and then accuracy may suffer. If the slug/wad are a "good" fit, I would not expect much difference. If the fit is tight, pressures will be higher. So saying a slug gives less pressure is not correct in every case.

Didn't mean to be a pill guys. I thought a solid projectile would give higher pressures too, but it turns out that the shot column actually exerts more outward force on the barrel and makes more pressure than a reasonably well fitting solid projectile. Does it sound counterintuitive, yup.

Haven't bookmarked the references to support that, but there are a bunch on this site, and some over at Shotgun World. I am not the shotgun guru here, but I have read the posts in this subforum going back to the beginning. There's a lot of good info. I sure don't want to "drive anyone away".

Try this guys http://www.google.com/cse/home?cx=001951264366462437169:ggn3vg-bjum. Its the custom google search feature for the Castboolits site. Look for posts by Turbo1889, Longbow, Videomemories, Blammer and others with shotgun experience much greater than mine. I suggest you type in "shotgun slug pressure".
