Anyone have any experience with these things? Mixed reviews on the Cabelas site but mostly positive.
I have a 30.06 Semi Auto that shoots a 7 inch group on a good day that I thought this might be worth trying out.
Here is the description:
From David Tubb, one of the most renowned rifle shooters in history, comes the Final Finish bore polishing system. By firing abrasive-coated bullets that you reload yourself through your firearm, you smooth and polish the throat and bore. This removes the rough spots and imperfections found in all firearms to greater increase accuracy and velocity and reduce fouling. The kit includes bullets coated in five different abrasive compounds and instructions. Please be aware that you must handload these bullets yourself to use this system.

If you have eliminated all other issues for the rifle shooting that kind of group, then what do you have to lose???
-
7" groups??? Ouch!! On a serious note I'd just be scared to use them. I just couldn't do it.
-
I have used Tubbs Final Finish in a couple rifles. It will polish the barrel and make cleaning a breeze. I did not noticed any change in accuracy good or bad in my rifles. I doubt if this is going to fix 7" groups and would look at your mounts, scope, and bedding first.
Good Luck,

I doubt if this is going to fix 7" groups
I agree. Polishing a bore of a gun that shoots well still might only result in a very small accuracy improvement. Don't expect this to drop from 7" to 3".
I have seen rusty barrels shoot better than 7" groups. There's something else going on there.
Good factory ammo?
Good reloaded ammo?
Correct bolt lockup?
Undamaged scope?
Tight scope mounts?
Iron sights?
Shooter competency?
-Sorry, I had to add that last one in. I've been around the firing line long enough to have seen just about every caliber of shooter.

no offence taken at all. I consider myself FAR from a good shot.
7 inch groups is probably a flipant comment on my part and is probably a bit of an exaggeration. Might be more like 5 inch groups.
Good factory ammo?
Good reloaded ammo?
-I get these results regardless of ammo (factory or reloads).
Correct bolt lockup?
-The gun is a Semi Automatic Remington Woodmaster. I have not checked the bolt lockup, but it seems to be OK.
Undamaged scope?
-I have had two different scopes on it, it is possible that they are both bad I suppose.
Tight scope mounts?
-I have made a habit of always checking scope mounts prior to sight in.
Iron sights?
nope. It has them, but I have not used them.
Shooter competency?
-like I said, I am not the worlds best shot. I FEEL like I shoot much worse with this gun than others. Consequently I don't shoot it much so I don't have any good data to KNOW if I shoot worse with it. I have recently started recording data and I ran a pivot on my shot group sizes by gun. looks like most of my groups are around 2 inches at 100 yards. see image below. There is no data for this particular gun in the table below.
I need to spend some time with this gun, but thought it might be just due to a really bad barrel. saw these things on Cabelas and wondered if it might be a "silver bullet" fix (no pun intended).

And yes... I name most of my guns...

When ever I get results I don't expect, the first thing I do is clean the livin snot out of the barrel. Which, with the bore polish, that's where you were going. But I don't know that the polish is going to pull you some couple or few inches of better groups. -Actually, that's doubtful. If you get a 1/4" from that process, that'd be getting a good ROI.
The 742's weren't known for terrific accuracy. The 750's are a bit better, but I'd expect less than 3" even from an older Woodsmaster. Before spending money on it, I'd let someone else shoot it to be sure there just isn't something about it/you that don't work right together.
Other than that, a good bore inspection is probably in order. Some fowling or a bur at the muzzle?
With an older rifle.. Longer heavier bullets will most likely shoot better. You didn't mention if you're shooting 110gn varminters or 180 flat nose.
Some guns aren't for some people.

i read an article on a rifle where they used the tubbs instead of a normal break in process in order to expedite the process. other than that i hadnt ever heard of it.
maintaining a 4.6/5 on cabelas with over 30 reviews is pretty good. America's masses havent been making great choices as a whole recently so i dunno what to make of it really. :rolleyes:
