 |
|
How does Schuetzen compare with Swiss and or goex on velocity and fouling when using the same volume of powder in cartridge?
How does schuetzen like compression?
I shoot a 50-90 paper patched with 500gr-600gr bullets in a 34" barrel C. Sharps 1874 Sharps. .494 Patched to .500, I neck size in a Meacham die and only let the cartridge enter the bushing about .200 with just enough tension to keep the bullet from falling out and stay tight on the top wad.
I have used BPC and SPG lube for grease cookies at .187" and .210" thick and have a nice greasy lube star after two or three rounds but seems to be dry in the bore the last 2-3 in. and fairly heavy fouling.
Ideas and opinions please.

Stop using grease cookies, didn't really see much difference with them.
For what its worth, Swiss is about 15% hotter than Schuetzen/Goex. Goex (latest batches) seem to be about 2-5% hotter than Schetzen. Seems to depend on the weapon and the bullet.
Compression: Generally speaking, Swiss and Schuetzen doesn't like compression where Goex seems to need it.
Fouling: From my tests and from the words of others, Schuetzen seems to foul the less of all three followed by Swiss.

Goex subcontracts 'swamp' maple for charcoal. Schuetzen and Swiss use alder blackthron (Schuetzen subcontracts and Swiss makes their own in house)
It's the charcoal! And the more sugar sap in the winter branches, the better the charcoal

Thank you Kirkland and John-Boy
Now more questions ???
When compressing the powders that like compression what advantages are are found or looked for?
When compressing the powders that don't like compression what disadvantages are found or looked for?
It seems that no matter how slowly and evenly I trickle the powder down the drop tube I can always tap or shake the case and get it to settle a bit more. My concern is that in transport and handling that if the powder settles then I end up with an air space  How much can the powders that don't like compression be lightly compressed before seeing the disadvantages. Thanks

Straight: It all depends on the Primer - Bullet and Crimp or no crimp.
One wants to maintain the best spiked pressure curve of the powder column. This starts with the briance of the primer flame.
There is no exact answer to your question. It is trial and error - load specific.
As for the air space Q' ... never leave air space between the powder column and the base of the bullet. The bullet base with the wad MUST be seated against the powder column. Otherwise, there could develop a ringing in your chamber or barrel.
Powder columns can be as little as no compression after the powder is settled to a generally accepted depth of 0.001 to 0.005" |

You question didn't specify if you were talking about fixed ammo or breech seating. In breech seating in the 32/40 with no compression you can get case stretching/separation. This is a real problem with Goex powder. I have used both Goex, Swiss and Schuetzen and all three benefit in the accuracy achieved with compression. Each powder will favor a different compression rate. One more thing to work with when trying to get the best accuracy possible.

In breech seating our bullets in 32/40 & 38/55 one has a air space, it cannot be avoided.

I compress all GOEX loads .270 which performs very well.
I compress Schuetzen .135 and it works excellent. |
