Better angle of cut patch?

[Saltner]

According to your experience and what has been written in various texts, which is the best angle to cut patch???

Example 1 30°

52 degrees.

I cut mine at around 40 degree's

[country gent]

I cut mine around 45* right now, but my cutting board is adjustable. I started with this angle and the thinking that the patch angles start and finish will be 180* apart. Im not sure yet but believe that the fit and consistency are more important than the actual angle of the cut. 2 wraps with a small gap between start and finish wrap to allow for the ofsett of the start of second wrap and the edges not over lapping is more important.

The drawing you labeled 30 degrees can also be called 60 degrees.
It just depends on which corner you take your measurement at.
I use the 60 degree ends.

If the methods employed by the Old Dead Guys has any value to you, here is a picture of some antique paper patched ammunition. Using an on-screen protractor, I measured the angle of the visible edge on the patch.

The resulting 58+ degrees is (essentially) the same as your 60 degree diagram.

True, we must carefully specify which angle you refer, inside or outside, however we understand each other!

The experience of our elders is like cast gold!!!
I will try both corners to see if there are substantial differences in the accuracy shooting

you still don't have it right

put your 30* to the top right, and the 60* where the 30 is

MC what caliber are those in you pic ?

Nope, the 60 goes where the 30 is & the angle labeled 60 is actually 120. If you draw a vertice going upward from the corner, inside the angle labeled 60, that 90 degree vertice will form a 30 degree angle between it and the upper leg of the 60 degree angle. :bigsmyl2:

I don't know, sorry, but I may have copied the image from a post by Lead Pot.
Perhaps he will clue us in ...

They do bear an uncanny resemblance to the 450/400 3-1/4 inch case MC which was loaded with black at one time.

I frequently use a 30-60 drafting triangle but sometimes juggle the angle just to suit the dimensions of the piece of paper.

[Don Purcell]

To me they look like 40-90 Sharps.

[bigted]

I was going to guess 44-77 or the 40-90 myself.

not having a clue about geometry ... I just cut what looks to me as a 40 degree angle and they both protect my lead and shed at the muzzle like I want them to.

laying my strips of paper down I mark the 40 degree angle from the top and down to the left and do this at the needed length of my wrapping paper needs for any particular boolit. somebody else may measure them angle wise from a different place and get a different angle ... but simply put ... that is my administration of my angle and it works good for me so far.

I had guessed 44-77, didn't think bout any of the 40's.

i use the single wrap chase 90 degree angle system on one of my .50 cals. and it shoots holes in holes.

Would that be a muzzleloader?

[johnson1942]

correct. 1/23 twist. 686 grain bullet. swagged to .50 then reduced to .495. slight cupped base. 18 pound paper single wrap,paper put on as i load. 100 grains of real black or 70 grains by volume of blackhorn 209. will take any thing in north america. a tack driver.

[Good Cheer]

What make of barrel and lock are you shooting Johnson?

[mikeym1a]

All I know is what I've learned from reading 'The Paper Jacket', and Paul Matthews advises a 30 to 40 degree cut, which is what I try to do. If I cut it too sharply, I have trouble rolling it properly. mikey

[johnson1942]

it is from kalispal mont. but they are out of bussiness now. my favorite barrels now are douglas, but i have 2 barrels from the oregon barrel co. and they are well made and shoot good. if you want to make a paperpatch muzzleloader and dont mind putting out just a couple of dollars extra, douglas. i found that green mountain has always a couple of tight spots in the bore, douglas doesnt and none in the oregon barrels either. now the tight spots wont make any diff. in shooting paperpatch but when your loading, its irritateing. 90 percent of the guns i build i use used thompson locks. i buy them off the internet on ebay. never ever have anything go wrong with them. even the expensive others i have had more trouble with, but thompson locks go on and on. the bore of the .50 case patch gun is 4 thousands deep lands and 1/23 twist. its a shooter. it has a mate in a target long range gun. same barrel but longer and thicker. i like to experment so i retired it as a paperpatch gun. i took my .50 throating reamer and relived the lands at the muzzle for about a inch or so. just took the lands out so the reamer is about .508. i then bought 500 mmp sabots in bulk. i casted up a bunch of .458 430 grain roundnose bullets. gave them a slight squeeze in a .459 swageing die to true them up and make them uniform. i shoot these in the target .50. they load real easy and i use 70 grains of black horn 209 powder behind the sabot. they are so accurate it is scarey. im going to set a gallon jug of water out at 400 yards soon and keep raiseing my soule sight untill it explodes. just finishing a .45 1/30 twist gun that shoots a 330 grain .440 pp bullet. just got it together this morning and put 5 rounds through it with out sights. just to see if it shoots and hold together. it did. now i have to do two dove tails and all the wood and metal finishing. used 70 grains of blackhorn 209 powder behind the bullet, it will be a light weight easy to carry hard shooter.
