Great video on seating depth testing

[Huntnful]

This was a great watch for sure. Some interesting numbers! Take away from it what you wish




My takeaways:

1. This is a 20lb+ straight shank barreled F class rifle with a smaller cartridge, shot by a shooter with a wall of medals. If I think my 10lb magnum rifle will shoot the same, I'm wrong. And if I think I will see the minute differences that he is seeing, I'm wrong as well probably.

2. Average 5 shot groups of .41-.46". The "best" 5 shot group seating depth shot from a .25" group to a .63" group.

3. Once groups were taken to a sample of 33 shots, the WORST small sample size depth, actually became the best, most stable load.

4. From "worst" to "best", the variation is about 10%. I put those in quotations because you can switch sample sizes around and also vary which one is the worst or the best.

5. After 100 rounds of seating depth testing, he almost came to an inconclusive result.



Interesting test for sure. Also why I quit messing with seating depth so much. It'd take me 500 freaking rounds to legitimately prove a 10% change in group size with a magnum rifle. And taking a group from a .7 to a .6 isn't going to kill me any extra animals until you get a LONG ways out.

I’ve watched this guy’s content a few times. He’s very dialed. I feel like he’s giving advice on how to race funny cars with a pro sponsored team while I’m still trying to get my hoopty to run a 12 second quarter mile.

I’ve had great luck with adjusting seating depth.

To each their own. Not nearly as much experience as others but I have found that some bullets will show a preference on the seating depth and others aren’t very picky about where they are seated.
I’ve noted some significant shrinkage of groups with a .020 change.

I definitely feel like ELDM's and Berger Hybrid Targets are super forgiving to seating depth variances. Which is what I shoot, which is why I don't care much to fiddle with it a lot

I just watched this on YouTube an hour or so ago and here it pops up on LRH….what a coincidence.

Conclusion? Inconclusive…or maybe we should stop worrying so much? But, what fun would that be. lol.

Watched that too. Having issues finding good grouping with 109 ELDM in 6GT. The easiest load I ever did was with 101Gr Hammers in a 6CM 7 twist. Less than 25 rounds. Another easy one was 243AI 8 twist with 88gr hammers.

Try opening up the neck tension. I've had great luck with .001 NT and ELDM's.

Winning in the wind has some great and informative videos but I also know he is light years ahead of where I’m at, his goal is never to see paper between shots, while I might get 2 or 3 shots with no paper, it doesn’t happen all the time. His rifles except for one 700 Remington are polished pieces of art, again, not mine, mine are hunting guns.

Watched a lot of his videos. Feel like a toddler trying to learn calculus. The guy knows his stuff and seems to be unbiased which is nice.

Now you've done it.

Rob's reloading is another good channel to watch.

Yeah I like his channel and testing also. Lots of side by side group shooting to show differences, or lack there of most of the time.

Also Ultimate Reloader.

I think he just reiterated that barrel timing result from bullet seating depths have different results at different yardages.
