Can any one tell me if an increase in patch thickness has an appreciable affect on chamber pressure and velocity?
I have a traditions .50 hawken. I originally went with 60gr of FFg, .49 ball and a .015 linen patch. This year I began shooting .018 pillow tick patch and 70gr of powder and noticed tighter groups. 2 inches at 75 yds.
I noticed the rifle kicked a bit more than it did when I tried 70gr and the .015 patch.
Then, I decided to try 70 gr of FFFg behind a .018 pillow tick and the rifle kicked like a mule (I came home with bruises) and not a single ball hit my 16x16 paper target at 75yds in a five shot string. I believe they were hooking to the right. Would going with a thinner patch when using FFFg increase accuracy and lower chamber pressure?
Any comments on what may be happening here?
