Bullet Pointing is all the rage in F-class, but the results of pointing can be either positive or negative. Come along with me as I describe my methods for testing bullet pointing in a live-fire test.

Really nice video. I enjoy these vids where only one variable is changed, and then groups are shot under the same conditions.
I've pointed and shot in excess of probably 10k 105 hybrids in PRS. A G7 BC of .282 or .283 is always where I've ended up. Two comments regarding pointing... length sort on OAL before pointing. Long bullets get smashed more than short bullets by the pointing die, so I point in large lots and adjust the die as I work my way through lengths. Likely also benefits BC consistency. Second is to not point too much. If you are altering the base to ogive measurement by your pointing process you are smashing them too aggressively. However, after years of doing this I'm seriously considering not bothering with pointing anymore. Pretty much none of the very top PRS national shooters are doing it.
Love the videos. Let's see some PRS footage. Keep that info coming. Simply the best channel for simple straightforward information 👏
Always great content Keith, thank you for all of the research and free information you’re sharing with us plus the quality video production
I used to shoot Berger 105 Hybrids un pointed in 850-1k VBR a 10 year run. They were good but upped my game to custom bullets, better results nearly the same costs…
Been doing PRS for a while, my average finish is in the upper 30%. I don't sort, tip, weigh or anything fancy. load them right out of the box and move on. I feel I'd benefit from changing my reloading practices however I'm limited on time and my reloading practices revolve around how fast can I safely (and satisfactory) accomplish this.
I’m more interested in the data you harvested for the unicorn Berger 180 hybrid- any chance of sharing ? Happy 4th
Sure, proper pointing results in a 6 to 7 percent increase in BC while decreasing the standard deviation of the BC.
Order them and wait a year.
@@FullSendPrecision only a year? In 3 years I’ve managed to purchase 200
Odd question but what desk lamp is that over your scale?
Hi Keith! I wonder if you can trust the Lab Radar output? This is a study in itself! Have you ever seen 3 of them read the same speed of a projectile?
I've put multiple chronographs together on occasion. There is always a few FPS difference on some shots. The reality is that every sensor system we use has tolerances. When we remove apparent outliers and average the remaining data, we have a better than even shot at seeing some truth in the data.
@@winninginthewind please define outliers in fps from the sample. I’ll shoot a shot and get a 40 fps difference, but the shot goes in the group. What should the attribution be luck ? :+)
Hey Keith! Not to change the subject, but what is your Brownell's code/link? I need to order stuff!
Thank you for your videos. They get me thinking!
TH-cam doesn't allow me to post links for them here. I have them publicly posted on my Patreon Page (free to use). www.patreon.com/winninginthewind
Keith, are you trimming THEN pointing or just straight pointing? I believe it was f-class John that stressed the importance of uniforming the meplat before pointing. I can’t say I’ve ever pointed bullets at all, just something I thought of while watching this.
There would be no purpose in doing so. The truth is that trimming reduces BC. Pointing afterward only hopes to restore the BC that the bullet had prior to trimming. I've run tests on 180 Hybrids and abandoned trimming entirely as a result. The only shooters I can think of that would benefit from trimming before pointing would be those shooting long range Benchrest and perhaps ELR. Just pointing served me quite well in F-Class.
Got it, thank you! I was just curious about that!
I dabbled with pointing 105 hybrids for a while but stopped for PRS for the same reasons that you bring up . One idea though… hybrids out of the box have inconsistent lengths. I found that pointing without first trimming resulted in inconsistent points since my pointer indexes off of the bullet’s base. This lack of uniformity must affect long range ballistics. Ultimately, it’s a rabbit hole that I gave up on
My key take away is the change in velocity SD ... something that you can only measure with the Labradar can measure or by shooting over multiple chronographs. Hand loading can get really nerdy. new t-shirt "Nerds make the best Hand Loaders"?
What about your PRS trainer rifle with the remage barrel
Always interesting
Sounds like...if you can point ...do it.
Every bit you can do might , does help.
Of course....practice might help too.
I figure to have best ammo for varminting...
But...wonder if worthwhile..
(I don't point)
But...
I can be happy that if I miss..it's me...not the ammo.
Very interesting 👌 so is that little machine on the bench, hmmm
Little info , testing using that would be nice,, great vid as usual 👍 spin my bullet please
Were the bullets sorted prior to pointing?
Yes
👍
Unrelated,
JBM > Patagonia?
Confused... What?
Spastic - LOL
