Cold bore zero versus (very) Hot bore zero “test”

[The Guide]

Practice less, not really the message.


From what I can tell, Form does two things. Shoot a lot, and Post here a lot.

You just read his 14,009th post, you have to admit, he’s still, not very good at it.


Not hard to surmise, that in both posting and shooting, it will take him longer than most, to get skilled. That’s okay.


What makes no sense, his wild assertions about people he never met, are as unskilled as he is.

I just read your 888th post and you're not very good at it either... Errors in spelling, punctuation, and grammatical formatting. Doesn't mean everything you do or say is wrong but your words expressed do not convey knowledge. You also assume that others do not have knowledge or skills that are greater than your own. Open your mind and learn. Try something new. Be vulnerable and admit you might not be the best.

He's got to be going for one of those call out invites to go get humbled and learnfor free.

Valiant effort. 9.5/10

I'd be lying if I said that thought never crossed my mind.

Okay everyone. Be on the lookout for a new account called eric1116 that starts telling Form he doesn't know how to shoot ...

So, Grammer over Content then???
i think i just learnt something, about you.

Hope no one with spell check, ever tells you to, "go jump off a bridge".

Am I the only one that noticed he said, he's smarter than the gun industry?

You guys must know something I don't. If he is senile or something, just PM me.

Don’t y’all hate it when someone crawls out from under their bridge to take over a thread and divert it with a gajillion posts that don’t add anything to the topic but instead focus on personal attacks?

 

[Shraggs]

Not only not add diversity of objectivity but is narcissistic and antagonistic.

At first it was something to get a chuckle with such stupidity. But once he started targeting it’s a problem…

This topic is fully hashed out anyway. I think the thread is a prime candidate for locking at this point.

Problem with locking is then the thread dies.

I did about 100 rounds of testing with a 223 and 30 rounds of testing with a 25-06 to look at group sizes and POI changes. I did not observe any significant POI shift from my 5 shot to 10 shot groups but in each case the last 5 shots always increased the overall group size in full power loads. Here is one set of 25-06 targets.

223 with a 10 shot group of full power loads



I checked a number of my 223 loads and they would shoot the first 5 close to .5MOA (more often under) and then spread out to around 1MOA (some under/some over) in the last 5 shots. This looks very similar to what Form posted--POI did not significantly shift but overall groups became larger.

So then I shot a reduced 223 load of 5 shots and took a pic. I then fired 5 more shots and took a group size. In the reduced load scenario the group did not enlarge nearly as much as in the full power load scenario.



10 shot group of reduced loads showing small enlargement



Anyway I'm sharing it FWIW.

It makes sense on some level. By firing 10 shots instead of 5 you have sampled more of your rifles true cone of fire. That group is never getting smaller since you measure group sizes from 2 furthest points anyway (I assume you do anyway) and you dont control whether any subsequent round comes from the mean or 2 or 3 SD away from the mean. An interesting wrinkle would be to shoot the first 5 at one target and as quickly as you can shift to another target and shoot 5 more and compare the group sizes.
