Hello Tinker,
No you don't have to do anything to it. Swiss has very few fines to begin with. They just take a little extra care with 1.5 Remember in BPCR the goal is low, single digit SD's.
If you do have a powder such as GOEX with a lot of fines you can 'sock it' get an old cotton sock, dump some powder in it and gently roll it around a bit. the fines will be caught in the weave.
Here are some velocity comparisons of Swiss V. Shuetzen (I had no GOEX)Schuetzen has a slight velocity increase over GOEX.
Note that the last entry for the 550 grain paper patched bullet I had no number for Shuetzen
30" barrel
45-70-300 SWISS 1.5F = 1480 fps
45-70-300 Shuetzen 2F =1400 fps
45-70-405 SWISS 1.5F = 1286 fps
45-70-405 Shuetzen 2F =1218 fps
45-70-520 SWISS 1.5F = 1175 fps
45-70-520 Shuetzen 2F = 1070 fps
45-70-550PP SWISS 1.5F = 1141 fps
In the 28 gauge and .410 I would suggest either 3F or 2F. In the 450 BPE I would suggest the 1.5 however there would be no problem with 3F though it is hotter and you will want to have a good lube such as SPG to prevent the chance of any hard fouling during long strings of shots. Also, with Swiss for best results limit your compression to no more than .125"
My rule of thumb is anything over 45 cal. I switch to 1F
I hope this helps!
Best regards,
Terry
