Wow, never had this happen with my previous rifles.
Almost all my patches are blown to pieces.
Accuracy is non existent.
Morning started great, shots touching at 50yds.
after a few groups, patches blown apart and accuracy gone, 5" groups maybe

70gr. 777 FFF
.490 ball
.020 ticking or .018 drill
Olive oil or mutton tallow

What rifle are you shooting? New rifle or old and lightly abused?

New Lyman GPR.
I have already Lapped the barrel, so no sharp lands.
Load goes down fairly easy, If I load same load but .495 ball it is very hard to start.

I think the powder is too hot for the lube or not enough lube on patches

T7 is close to Swiss, so I wouldnt think the heat is the cause.

If the patches are good, then go to the crapper, i'd suspect that the bore is becoming fouled and causing stress on the patch as you load the next ball down.

Once you see them start to show up blown, fully clean the bore and try it again.

Tried that, still blowing patches.

Try this clover valve compound. Greece up a couple patches and give both 25 times up an down barrel this will take out manufacturers flaws. Then clean with window wash cleaner pop 3 caps then load and try again
