Difference between 2f and 3f Schulze other than grade?

[dan101955]

I have both 2f and 3 f bp.what are the difference other than grade, of the two powders.

With the same volume of powder 2F will create a bit less and a build it a bit slower. It will also create less velocity.

Typically .50 cal rifles has been thought to be the pivot point between 2 and 3F. However many people use 3F in much larger calibers and some even use 2F in much smaller calibers as well as pistols. And pistols generally call for 3F.

General rule of thumbs seems to be to reduce by 10% a 2F load to keep the pressures/velocity similar.

Wrong, when going from 2F TO 3f, you reduce by 10 %

I think we have a learning opportunity here

"Grades"...Refers to size....which equates to burn rate or rate of deflagration....which equates to pressure and velocity.

All of this equates to everything from ease of ignition to accuracy and destruction of a firearm.

I should have said, I have a 50 cal. T/C Hawken that I shoot. I just received my order of bp. I have both 2f and 3f.
I shoot 65 grains 3f with a 480 ball and .015 patch.
I want to try the 2f,so what powder charge do I use to egual the 3f.
I read the manual and it stated that the Hawken shoots 2f.

Try 70 then 75 if still shoting low at all

Both grades of powder have the same composition. The only difference is in the granulation, the size of the granules. Of course, the difference in granulation has the effect on its performance just as Rodwa explained in his post.

Dan, if you are shooting 65gr. of 3f, I would just start with 65 gr. of 2f and see what happens. If you are target shooting it may drop your point of impact a tiny bit. If it is a hunting load for deer, then the 65 gr of 2f will have a slightly lower velocity at any given distance.

If you are trying for accuracy, then use the 65 as a starting point and move up or down from there.

I think the 10% recommendation is a good one if you are looking for similar muzzle velocity.

It will not make any notticeable difference in performance. You might need to use slightly more to get the same velocity, but you would need a chrongraph to tell. One thing that larger grain powders do is to kick less. I precieve the acceleration to be slower and thus less felt recoil. 1F will be very notticeable, especially in large bores.

Just noticed that the can marked Re-enactor grade.

 

[rodwha]

Yep. That's what I meant.

Just noticed that the can marked Re-enactor grade.

means it doesn't have a fine graphite finishing like fffg that g at the end means a graphite finish

your powder will do just fine, use it up

I thought re-enactor grade was "floor sweepings"... :wink:

I noticed the title of this topic is "Difference between 2f and 3f Schulze powder.

I'm sure it was meant to say "Schuetzen powder".

I didn't know Schuetzen made a reenactor grade of powder so I did a little web search for "Schulze gunpowder.

Much to my surprise, I had a hit! (Sort of like tossing out a bare hook and having a big trout grab it as it hits the water).

Anyway, I did find that Schuetzen does indeed make a reenactor grade of powder.

Getting a bit off topic, the thing I found was about "Schultz White Gunpowder".

It was invented back in 1868 which isn't very far outside our time limit period on the forum so, although I won't go into the subject, here's a link to the article for those interested.

Good Lord that was hard to read! :surrender:

 

[coloradoclyde]

Reminds me of the story of "Exploding Trousers" https://en.wikipedia.org/wiki/Exploding_trousers

 

[Zonie]

Well, there you go !!

Your link confirmed my suspicion.

Getting black powder on your pants won't cause them to explode. :rotf:

Should have been Scheutzen.

Spell check sucks....

 

[dan101955]

I will try this again. Totally confused myself rereading my post.

I was shooting reenactor grade bp. 65 grn. 480 ball& .015 patch.
I have a Springfield 63 58 cal., a 58 Remington .44 cal, and a.50 t/c hawken.
I would like to shoot only one powder. I would like to shoot 3 fg Schuetzen.
What would a good load for these weapons.

Dan

I did work up a load that I liked for the hawken I liked.

65grn reenact or 480 ball .015 patch.
