One more question...have the various number stayed pretty consistent performance-wise over time...for example, did you notice any significant changes to the burn rate when they added the decoppering...

i am curious to how N140 and N150 relate to each other? i know N140 is faster but looking at various reloading data it seems that it is only slightly faster meaning there is not a whole lot of...

My cheapest mauser was Chilean '93 in 7x57 for $26 that I won at an auction. At the same auction I won a swedish mauser '94 carbine for $150 so that is my favorite mauser.

I was always intrigued by Vihtavuori powders but never tried them because of their higher price. Well, it turns out, given the current price for Alliant powders, the Vihtavuori powders are actually...

Yes with 45acp and bullseye. OP said No5 was being used and that is a ball powder and ball powders tend take a bit more energy to ignite so I would think powder position would be factor for sure. ...

Probably powder variation in case is culprit.
Less powder in a case means more space. More space means powder position varies more. Take your minimum loads and raise muzzle up before firing and...

Well I now better understand the root of your difficulties.

Ah, a great question. The wave is not traveling through the bore. The wave is traveling through the metal of the barrel. It is well known that a barrel vibrates when fired. Very similar to taking a...

I agree most powders would be difficult if not impossible to detonate. However, high NG powders like Bullseye will most certainly detonate under the right circumstance.

Relative to 'wave...

"Powder was packed in neck & shoulder so tight that I had to use a a small std screwdriver to pick it out chunk by chunk. Considerable amount of that powder which remained in the case was no longer...

Wow, I asked two questions and got years worth of experience in return. Thanks everyone.

Lots of great suggestions here. Yes sometimes I do cut the spruce too soon and that means slow down. That happens on my lyman 429383 which takes longer for the spruce to solidify. I understand...

I cleaned these up by heating with torch already so do not have any real useful pictures to share. I don't like using a torch hence the reason for my post.

I forgot about using a pencil...I did...

Invariably when doing a marathon casting session I get a build up of lead on the mold surface usually on top associated with the spruce cutter.

First question, how do you remove that. I tried...

Well I measured the density of those bars and found that the larger bars have a density close to Sn60/Pb40. The smaller/thinner bar had higher density near Sn50/Pb50.

The manner in which I...

So these do not bend easily but are bendable by hand with enough force and these do not have an indentation. Yes, I am considering check the melt temp as suggested by others as well. I didn't know...

Some things mention here which I didn't think about. Thanks everyone.

I think I will measure the density and see where that leads. 50/50 Solder has density 0f 8.87grams/ml. Easy enough to do => weigh bar and convert to grams. Roll up and place in ml graduated beaker...

I was rooting thru my lead stash and found what looks like solder bars. There is no letters or markings on the bars. Any suggestions on how I might determine if these are solder bars other then...

Thanks for reply. So 50/50 Sn/Pb bar is by weight not volume, simple enough. Did you know that a true pound of feathers will weigh less than a true pound of lead unless weighed in a vacuum?

So if I have 1 LBS bar of 50/50 Pb/Sn then it really is only .5 x 7 / 11 = 0.31 Lbs tin (factoring the density of tin to lead)?

Hmm, being doing this wrong then because I just figured 50% of 1...

Thank You for quick reply.

When using the Alloy Calculator, are the % values for Sn, Sb, Pb in % weight or % volume?
