Eric Cortina and Hornady

I don't know if I will ever be able to trust Hornady.

1. Way over stated BC.
2. Denying the 6.5 147 ELDM still has a blow up problem.
While I use some Hornaday bullets with some success for varmint hunting / predator hunting, I don't know any serious match shooters that uses them.

The biggest advantage I see with them is that they are available whereas Sierra and Nosler, my two favorites are as scarce as a conservative in California.:rolleyes:
 
When I first started into long range shooting I consumed everything I could find online by the names I saw on sites and records. Erik being one of them. I watched everything he had posted, and if taken as a whole, you can see the patterns in his content. Just look at his "stop neck sizing" period, he posted his video, got a bunch of exposure, but then went on to post cellphone videos walking the pits at matches asking everyone who is anyone how they size brass. But, if you pay attention, not all of them answered a clear cut yes or no, until he corners them into it. So his dogmatic ways of reloading have become very common.

But, let's face it, to make a name for yourself online you need exposure. He has never been afraid to get his name out there and point in fact, here we are discussing him and his info delivery without him even being part of the conversation.

Now if you had an average involved shooter looking to get into F/class, Erik's videos are far more engaging than Keith Glasscock's, but both are extremely informative and helpful, but other than our small corner of the shooting community, which name do you think more people know?
 
Jayden said in the beginning of the video in order for the average of a gun to be a 1/4 min. gun at some point it had to shoot 1/2 min. That is not true at all. I personally shot these 3 - 10 shot groups recently with my 30BR. The agg. for the 30 shots is as follows

.325 10-SHOT GP
.198 10-SHOT GP.
.253 10-SHOT GP.
.776 TOTAL FOR 30 SHOTS
.258 AGG. FOR THE 3 10 SHOT GROUP
The largest group my rifle shot was .325 and that is nowhere near 1/2 min group.

Many of his statements are generically correct, but practically not appropriate. He and Litz are way off base by claiming the SD of the groups sizes equals 0.3 times the average group size, which is simply what they observed for their study, and why they state these large group sizes that you might have a 0.001% chance of seeing. There is no statistical or physical reason that this is a rule. It is also known that small group sizes do not follow a normal "bell curve" distribution as the groups cannot get smaller as they approach 0, but they can get much larger. But this is just one aspect of how they have convoluted the statistical logic!

Thank you Charlie for shedding some light on this topic. I totally agree with your statements. I realize that if in fact I were to continue or extend my 3 sets of 10-shot groups into say ten 10-shot groups I may see more open groups and more tighter groups but I do not believe it would be due to or based on a theory that says at some point my rifle would without fail shot a 1/2 inch group. That to me simply is folly. I say this because unless it has been while I was actually working up a load with changing powder charges and/or seating depths this rifle has not shot a group that measured 1/2 inch @ 100 yds. and I frankly don't ever remember seeing it nor does it show up in my data log.

For clarification, I'm not a competitor in any of the civilized shooting sports. I am very grateful that I have a window into the experience, knowledge and accomplishments of the many top competitive shooters in all those sports as they offer to us a broad stroke of knowledge to gain from. I feel that same for the manufacturers who provide me with components I would otherwise not be able to build myself.

With that said I also do not have an exposed nerve to be offended and my only ego is that destined to learn as I am a student first of what I don't know and instructor of only what I know I know. I think I fully understand the points Erik is making and fully understand the results Hornady has published and can recognize the value of both. I don't look at it as who is right or who is wrong, rather what I can gleam from either, to use to my advantage and Thank them both for their investment. On the other hand I also appreciate that different folks who disagree are willing to share why they disagree.

Erik is a personality, there is no question about that!

I'm not trying to be Erik. I would rather quit shooting than engage in the ambush interview tactics that Erik uses. Ever notice that I always wave him off?

Far too many people concentrate on the weird reloading stuff that top 10 shooter swear by. Honestly, we all do things that look suspiciously like superstition. The simpler I make my system, the easier it is for me to shoot the scores necessary to obtain those shiny neck weights.

For me, I have really cut back on the amount of YouTube content I'm making. Instead, I am focusing on my Patrons. They are the ones that make it possible to run tests, and make videos. You would be shocked at the expense doing such things entails. It just isn't worth it to put information out for free in many cases and deal with the endless trolls that pop up.

You have to remember what YouTube is at its core: An advertising platform. Have you noticed that everyone is trying to get you to buy stuff? Either stuff they make, or stuff they have a deal with the seller on? Even I'm selling something - my time answering questions, having Zoom meetings with individual Patrons, and the like.

I had thought about doing podcasts, but decided against that for a variety of reasons, not least of which is the fact that I can't bring myself to sit and watch anyone else's podcasts...

Back on subject:

Making videos and learning stuff for my team and patrons has netted me a lot of information that I would have not found otherwise. For example, I shot a very large sample for chronograph data while doing some large samples on tuning and group size. Oddly enough, there is a normal distribution of group sizes when you put over 100 rounds into the berm. If I take a standard deviation from those group sizes, I see that there is the likelihood of having an exceptionally large group and an exceptionally small one as well, over the life of the barrel.

On the other hand, I also wonder a bit about using group size at all for determining the precision of a rifle. Some other measurements show promise as better means of determining our likely outcomes from shooting very large samples (like an entire barrel worth).

Well, I watch more of your videos than Erik's anymore, as I get more actual info from you than his. I didn't want to mention your interactions with him to avoid sounding like pitting one against the other as both of you are accomplished shooters.

Too many videos for everything start with "This hack will make you 1000x better at..." and its no exception in the shooting community. I enjoy your content.

BTW, been meaning to join your patreon and just did. Thanks for all you do!
