Taconator87, The normal tool for polishing the crown is a brass lap with wet lapping compound. The lap is inserted in a drill chuck then spun. The angle of the brass lap has to be the same as the crown angle. Normally you do not lap a handgun crown because it is a lot of work that doesn't do anything but make the gun look a little better. You can do more damage than good if the lap is inserted in the muzzle at an angle.

Here's what a 45deg brass lap looks like:

Anything that touches the rifling on the crown can and will effect accuracy.
If it bothers you, just don't look at it.
Sorry to sound like a smart a$$.
I myself speed hours and hours polishing on my stainless guns.
I NEVER touch the area around the where the barrel is crowned.
I would polish the end of the barrel, but stop where it angles into the crowing.
Good luck enjoy your toys, and shoot them often.

Just so we are all clear about the "lines" i am referring too, I highlighted and circled the area, LOL, I don't know why I didn't do this in the first place. Again, its hard to see the real depth and look of the lines due to the pic taken from camera phone. As always, all opinions and serious advice is welcomed. I don't have a local gunsmith to take it too, im am a shooter...not a gunsmith. gp100.jpg

I picked up an SP101 today and, honestly, the tool marks at the crown are worse. In fact, I'm really a bit disappointed by the overall fit and finish. Realizing the tool marks in the crown may not effect accuracy, I can't help but wonder what left the tool marks fairly deep and rough? Dull cutters?

The internal parts are cast of course and have slag and burrs everywhere- some in areas critical to function. The external finish appears to be done with a wire brush with brush marks in all different directions and uneven in depth and luster.

Function appears fine and I wouldn't expect much handwork on a production revolver - but the SP101 is significantly more expensive than the SW642 and my Smith displays better finishing. In fact, a former duty revolver, a 1985ish Security Six displays much superior workmanship.

Taconator87, Maybe I didn't explain it well in my previous post ..... the muzzle's point of exit is where the rifling stops. The "cone" section of the crown does not touch the bullet so it doesn't matter how smooth it is. Some people tend to put way too much emphasis on a crown. Yes, in a precision rifle crowns are very important but in a handgun, it honestly doesn't really matter.

Looks like dull tool bit chatter marks. Should buff out.

I have the same thing in my GP100MC. I was wondering about it but never thought too much about it.

I'm glad someone asked, I learn something new everyday!

I'm curious does anyone know exactly what angle the SP101 crown is? Is it a 45 degrees like what is shown as an example from Iowegan? I need to take a closer look at my SP101 in 327 Federal.

I understood what you were saying Sir, its just that Ruger used to polish the "cone section." My Super Blackhawk made in 1998 is very clean. It seems like ever since Ruger started these 48 Billion gun challenges - QC on fit and finish took a back seat. Again, you should see the cone section of my SR1911.....looks like someone crowned it with their teeth, lol, that had to hurt.

All jokes aside, I may quit buying Rugers, I don't have any finish issues with the S&W, Remington's, Colt's, or even Charter Arms....yes Charter Arms, that i have purchased in the last 2 to 3 years.

I may even sell the most of my Rugers off, however Im keeping the GP100 and Super Blackhawk

Again, thanks for your input it has been quite helpful

I did an experiment yesterday.....turns out 9 out of 10 new rugers from various gun shops, and friends guns, had these same marks. I guess Ruger quit polishing that area to save time and pump out more firearms per minute for their 100,356,387,767 gun challenge

Imma sell the SR1911 to purchase a S&W combat magnum - the 5 shot 44 mag. Im not a fan of the internal locks, but hey that is what S&W is doing these days

Nope, I'm not trilling at all. Just asking questions and venting a little bit. That is what discussion boards are for.
