Using the SubMOA app to measure load development groups

[@brianjazek7769]

Just downloaded range buddy on my android, they're exactly the same and your video made measuring easy and amazing! Can measure when I'm out shooting now

[@FClassJohn]

Awesome! Glad it helped.

[@patrickcolahan7499]

Thanks for sharing this John. This will definitely make evaluating my development targets much easier.

[@FClassJohn]

Glad it might help.

[@brettinnj]

You always manage to find cool stuff. Thank you.

[@FClassJohn]

My pleasure! Glad it helps.

Been using this app for years under the name range buddy. Love the Mean Radius Measurement. Using normal group size measurement, you only measure your 2 worst shots...wasting all data besides those 2 datapoints. MR uses all the shots as data, which increases your confidence that the result is repeatable. Another nice feature in this app, when you put the white info box on the screen, it shows the aggregate results for the target. If testing a new powder/bullet combo, although you may find one good group on your target, if the majority of the groups are bad, the aggregate group size will reflect that. I have used that to eliminate powder/bullet combos before wasting too much time on them. If the majority of the target is bad, its unlikely your 1 good group will be repeatable, or unlikely that node will be very forgiving.

[@FClassJohn]

Great advice. Thank you!

[@Sharberboy]

That's range buddy on android

[@FClassJohn]

Thank you.

Looks like it's called Range Buddy for Android

[@FClassJohn]

Good to know, thank you.

John you'r not CHEAP!!!! Your're FRUGAL!!!! :-)

[@jims261]

Thanks John

[@davidjackson9712]

It’s definitely a great app. When I measure a picture on a target without a grid, I just use the grease ring of a bullet hole to measure for scale. It’s not a perfect way, but it gives you something to go off of if you forget to add something else of known size.

[@FClassJohn]

Good idea, thank you!

[@planeurable]

having used the Bukys tuners on my short range BR rifles since 2010 i have observed some typical patterns when you are far from a sweet spot : left and right diagonals , exagerated vertical and straight horizontal are typical ( when that load was shooting dots before screwing the tuner ) ; triangles with white paper in between each shots is also typical , although now i seldom shoot a third when the first two aren't touching.

[@samclements3692]

Great info, thanks John!!

[@glockparaastra]

Awesome! Thanks. Very useful!

[@georgewilson60]

Great app, been using it for years now.

[@FClassJohn]

I understand why. Can’t beat the price and the functionality.

[@soonersteve3733]

Thanks John! I’ll get it.

[@ronnydowdy7432]

I like it. Thanks for sharing

[@jackd.jeffries3358]

Nice simple App, thank you.

[@FClassJohn]

You're welcome!

[@tadeloach22]

This is AWESOME! Thanks for sharing it.

[@FClassJohn]

You’re welcome

[@JacobTerherst]

I prefer to use the "thumb in picture" method to size my groups while my thumb is covering up the impacts that "don't count". Just kidding, but everybody knows that guy.

[@FClassJohn]

😂

[@larrythorpe2944]

Thanks for your effort of making video, to really looks good, but I am struggling to get going. After taking photo I get no green crosshair to measure known grid size, so cannot continue. Any idea what it could be. Regards Larry.

[@tacmedic5211]

Have you compared this to the Ballistic-X app?

[@FClassJohn]

No I haven't, sorry.

[@fentonpainter7907]

@@FClassJohn it’s very similar. What I’m currently using on my iPhone at the moment.

[@markg7762]

nice target can we down load the pdf

[@arronhamilton8091]

@fclassjohn I like those targets that you are using for load development, where can I find them to use myself?

[@tinfoilsombrero1439]

That’s damned handy. Thanks John.

[@FClassJohn]

My pleasure. Glad it helps.

[@andyamor3344]

That target you are using John looks awesome, where can you download it from. It looks better than the one you posted ages ago to download free. Love the channel buddy always something to learn. Cheers Andy from Australia

[@long-range-eliminator]

John where can i find targets like this ?

[@gordy1961]

John, there are 3 million of us wanting to know where to get those targets... can we download them.... where from....? Cheers bud

[@gristlepounder]

Very cool.

[@MrHf4l]

Hey where can I get that target?

[@jturner5227]

I like the target. Where did you get it? That is a good app. I have it too.

[@tallyman15]

Question on measuring group size. Some say center to center, some say outside to outside, some say inside edge to inside edge. What is the standard?

[@FClassJohn]

In my circles most use center to center but the reality is that it doesn't matter if you're using this for your own benefit. Just be consistent in how you measure and you'll know if you're improving or not.

[@taylorbokshowan5713]

Centre to centre is standard

[@RichHodyl]

John: Really enjoy your content. Question: Do you use a Bullet Genie or similar device? Second question: Roughly how many (in terms of percentage) would you estimate of the top 60 F Class Open shooters use one?

[@FClassJohn]

Yes I do and I don’t think as many as you’d think do.

[@RichHodyl]

@@FClassJohn Thanks for getting back to me. I have wondered how one sorts with the Genie - sort by OAL then sort within groups using the Genie? Or some other way? Also, I wonder if the Genie can be proven to actually tighten groups more than if it wasn't used (especially after using great brass, great bullets, the best scales for powder, great powder, etc). If it isn't obvious already, I'm toying with the idea of buying one, just hesitating because a year from now I don't want to feel like the Genie is really just a a $1,500 tackle box....thanks again for all the content and comments.

[@tacticalrabbit308]

Google play doesn't list it on Android 😭☹️☹️☹️

[@FClassJohn]

Someone in the comments said to look for Range Buddy on Android

[@ralphproudfoot620]

That's a great app for free.For my simple mind calipers and a pencil work for me..lol

[@thompsonjerry3412]

Does it have snotty comments?

[@travhammer]

Man. Give me back my dial calipers.

[@badoldboy5557]

nice - but not for android -

[@dcarson]

It’s called Range Buddy for Android. Something about the name way taken in the Apple Store at the time so he had to change it.
