Hey Log Eye,
I use Dutch Schultz' Method 'dry lube',aka: the secret papers.
Now that Cabelas gun has a chrome lined bore, and it did shred patches till I shot it a bunch. I use a tightly woven cotton denim (like bluejeans) that measures .024 and crushes to .0115, lubed 1-7,one tween shot swap using a cotton .22 cleaning square wet with spit. I found 80gr to be the most accurate, beyond that the groups spread. The outside of the patch ends up a bit tattered,yet the center is intact with just that proper redish burn circle and tiny cuts from the rifling lands. If I don't swab,then the patch shreds to pieces. This is cut at the muzzle,strip patching.
It's a darn snug fit,this patch and a .535 ball.
777 is hotter and performs way different than Goex, don't mixm',start with a clean bore,if you had a good load at 80 with Goex,I'd drop back to around 70 to find the same results.
I've been messing with Swiss of late and find it a real pleasure to use.
I did have to add just a bit more lube for the Swiss,1-6
I hope this helps sum
