Two points: 1) I own a PIetta Starr SA. In a word, it's a POS. Well, ok, that's 3 words. The gun is unwieldy at best - the bore centerline is high relative to the grip making follow through difficult. It's difficult to point if you're used to the Colt grips. The gun is a top break design...

"Eyeballing" the 5 grain mark is easily good enough. Even if the error is as much as 2 grains that small amount of powder is not going to be significant for everything except perhaps match target shooting.

How about, "...the conical design allowing for a smaller drag coefficient..." Yes, the conical front doesn't by itself guarantee a significantly better drag environment, but it does allow the designer to do better with judicious choice of aft end shapes.

Deleted. Apologies for hijacking the thread. I'll shut up now.

Yeah, this has really gotten silly.:banghead: Yes, we poor uneducated black powder shooters use the word 'grain' to describe a volume measurement, something the world's governments do not endorse (which some folks would consider sufficient reason by itself:scrutiny:). I suppose it will lead...

Umm, I think spherical and conical bullets of the same caliber have the same frontal cross sectional area...

Interesting stuff. But... Nobody establishes the accuracy of their equipment, which, after all, is of utmost importance. Was the volume measure used to create the Cutrich.com conversion chart accurate to 4 decimal places as suggested by his data? We don't even know if it was accurate to 2...

^Good advice.

Yes, they do. The fact is that black powder is not 'unstable' with respect to impact, friction and static electricity. The physics just don't support such nonsense. An MSDS is not a scientific document; it's a legal document, intended to cover someone's butt from attack by ambulance chasers...

The MSDS for black powder from Goex, under Hazardous Reactivity - Instability, contains the following statement: "Keep away from heat, sparks and open flames. Avoid impact, friction and static electricity". Perhaps that's the source. Having said that, I personally believe the admonition...

Decide what volume by grains of fffg real black powder you wish to shoot. Multiply that number by 0.85. That is the volume by grains of fffg 777 you should load. Completely ignore the weights. That's all there is to it. For instance, if you want to shoot the fffg 777 equivalent of 35 grains by...

No. I buy guns to use. I don't have 'safe queens' (well, except maybe for that POS Starr SA...) nor do I keep non-functioning piles of parts. Now, some don't get used very often as I do have favorites, but they're all available and working.

Seems reasonable to me. Since physical properties are never perfectly exact, even from lot to lot of the same powder... What sort of error term would you require for 'equivalent'?

Walkers only came in .44 cal. It's a special gun; very large and heavy, capable of firing rifle loads. In general I would not recommend it as a first cap and ball revolver. The 1851 Navy, 1860 Army or 1858 Remington New Army would be a better first choice. In used black powder revolvers...
