Tubb's Final Finish Bullet Kit Worked!!!

[baldhunter]

I had a difficult time finding a load for my CZ 550 Ultimate Hunting Rifle 300 Win Mag.About a 2 inch group was the best I could get out of it at 200 yards.OK,but I felt like it should do a little better than that.I was thinking about getting a custom barrel put on it,but before I did,I thought I'd give Tubb's Final Finish Bullet Kit a try.I was amazed,I could see my groups start to tighten up after the first five shots.By the time I got to the last bullets in the kit,I was shooting a 1 inch group at 200 yards.That was the best this rifle had ever done.The other day I finally made it back out to the range to try a few test loads to see how it would do.I think I'll stick with this one!

Good report and good to know.

Thanks and congrats!

Didn't hurt a thing to try it.
Should copper foul less now

Always good to see first hand experiences.

The Tubb FF has worked for me both times I've used it.

Once on a new Remmy sportier 338 RUM take off bbl. Wished I would have shot for accuracy first but didn't. After the Tubbs process she broke in to lead free in about 15 shots and is super accurate and a dream to clean.

Once on a shot out 270 Allen Magnum. This bbl went from 0.25 MOA accuracy to nearly 1.5 MOA @ 200.

The Tubbs process brought it back to 0.25 MOA which made me feel really great. . . but. . . for only 15 more shots. . . :roll eyes:

Go back and shoot a five shot group and report back. I've shot some amazing 3 shot groups -- only to be disappointed at the end.

Seems like the Tubbs bullets did help, regardless of my caveats. So I am not saying that they are worthless.

But the statistical probability that you shot a great group "randomly" with a 5 shot group is far lower. 3 shot groups only really tell you where to put your further research....

Don't forget one shot groups,, as this matters most in LR hunting.
3 or 5 shots touching -somewhere on paper, is not equal to 1 shot cutting center of mark.

Grouping is used by hunters to delude themselves about their shooting system performance.
It steers their minds from accuracy to fixate on precision.

You can go to another world in shooting with 3 shots:
Pull a gun out of it's case, set it on a bipod in the dirt, as you would in the field, and put one shot into a 1.5" bull at 300yds.
Put the gun away, drink a cup of coffee, and then pull it to shoot once on a 2.5" bull at 500yds.
Put the gun away, drink another cup of coffee, and then repeat another shot on a 1" bull at 200yds.

This is 3 shots with entirely different meaning than a ragged hole group at 100yds.
It means you're ready to take hunting shots to 500, or not (and that's it's time to **** somewhere).

This is darn good advice! But if I were drinking that much coffee my shooting skill would diminish so I will have to switch to water after the first cup.

Once I have a load dialed in and set up this is how I practice. My last session was 2 shots, 2 1/2" apart, into a 5" black dot at 850 yards in a 10 mph FV wind and 20 degree temps. I got up between shots stretched got back behind the rifle and sent another to make sure it was not a fluke. The next round out of that rifle was my wife's first bull at 765 yards and she stoned it.

Great way to build confidence and also prove what will happen when it is time for "the shot"

****. Awesome
The coffee simulates stalking to get the higher percentage shot

To be fair -- we all develop loads under "consistent" conditions. You want a load that is shooting well into a small group first. THEN, you should test it at different ranges, first shot, cold barrel etc....

When I posted about 5 shot versus 3 shot groups, I was merely pointing out (from personal experience and a bit of statistical knowledge) that shooting a good 3 shot group can happen, and it might just be pure luck. Shooting 5 into one hole leaves little question -- the load and gun and shooter were working well under those conditions, no questions asked.....

I've stopped using 3 shot groups for any gun that I have even a clue about its accuracy. A gun capable of .5 MOA is going to shoot almost all of its test loadings into less than 1.5 MOA. The statistical variation in three shot groups versus 5 shot (or 4 shots) is much greater. That means I have more trouble knowing if the group I shot was really better, or just random.

5 shots leaves little doubt.

What I do often find is that on a bad day (lots of wind, my eyes not working well etc), when shooting 5 shots the groups all end up being about 1.5 MOA. Tells me the other variables are exceeding the variation of the load. Now, if I had the ultimate luxury of shooting 10 shot groups, even under less than perfect conditions, I could perhaps tease out the trends towards one load or the other.

Unfortunately, in such situations, the "sample size" that allows a precise statistical analysis, is not really feasible....

+1 for what Mikecr wrote.

But I did like what Tubbs Final Finish did for my factory barrels.
