Been working on the 45. Cast some pure lead bullets. Rolled them in the compound between a couple
plates. I used fired cases [unsized & slightly belled] & 3 grains of Promo with the bullet seated
against the powder charge.

What were the results? Did it smooth things up?

After 6 rounds I cleaned the barrel & fired 6 more
cleaning again. This really brighten things up. That was
last week but after coming home from fishing camp
yesterday I decided to make 12 more bullets, load &
repeat the process today.

After the first 6 the bore really looked great. I fired
the last 6 & came home. I had another sixgun & one auto
with me so I cleaned them & Barbara yelled soups on so I
haven't took a good look at Ruger yet.

I will say the pin gauge falls through the barrel with no
restriction.

I have done this once, using ordinary auto valve lapping compound. It comes in two tubes, one rougher than the other, used the rough stuff for five rounds and then several of the less coarse stuff, cleaning pretty frequently. It did make it clean easier, but I can still see the rough portion of the bore, I was kind of afraid to do much more.

I have used valve lapping compound on a few of my rifles and they certainly are easier to clean and I had to clean less copper after that.

I also used the same compound on my bullet molds that I wanted to drop a bit larger or that were dropping slightly out of round. I drilled a small hole in the center of the base of the bullets and screwed in a hex head screw. Placed screw head in my drill press and clamped the mold around them before turning it on. Done that with about three bullets cast from the mold.

Then I cleaned the mold and molded more bullets and done the same with them. Repeated a couple more times until I was dropping nice rounded bullets that were proper size. I used bullets that were fairly hard for this process.

Hard to take barrel pictures with a phone but here is the typical Ruger barrel. The place in the second photo
was there when I purchased the gun.

Lynn,

I wasn't thrilled with the performance of my Vaquero .45. It's best groups were 5"-6" at 25yds. The throats measured .448"-.449" with a .451" groove diam.

I honed the throats to a consistent .4525" and then fire-lapped it. It shoots very well now with groups around 1.5"-2.0" at 25yds.

One other thing I did was to remove the ejector rod housing and unscrew the barrel from the frame. I used a dremel polishing wheel and buffing compound to smooth the forcing cone to a bright finish.

I think it was all for the good of better performance.



Mike

I think this forcing cone could use a little polish.

I don't know why in the hell Ruger does this!

All mine have tight throats too, but luckily more like .451".

Still too tight. Cut the things .452-.453 and cast and jacketed will be ok.
