Your last few "interviews" have had an unbelieveable amount of information that is so valuable for many shooters that have not made it to your level of knowledge. Thank you sir.👍
'maturity'...great, simple statement. how you absorb and use information has a lot to do with maturity, and how 'open' you are to accepting and integrating new techniques into your work...
Thank you for what you’re doing Eric, all of these interviews need to be watched again due to the density and amount of information. I wanted to confirm what you said about seating depth, after your initial/rough powder test if you have a tuner(I have yours) pick a seating depth and then adjust the tuner shooting groups at each setting. After arriving at the best setting move to your fine powder test. Thank You!
By far one of the best episodes yet. I have all Brian's books, for this reason. I shoot like 8 different cartridges and his books have helped me understand this game a whole lot more.
Erik Cortina, I'd love to see you do a comparison video of the OCW method vs your method of choice. I know you are open to new ideas, and I think we'd all benefit from seeing that video. Great video!
This last 20 minutes is incredible.Eric I struggle with the same question change BC or speed and I have not got either to give me the results I would expect.Please re visit this topic .Standing by .Thanks
Caylen seems like a good dude. I'd do a jump with him, and I don't say that about everyone. I love going to different type matches, and I have had BR guys come up and ask me about my PRS rifle, and I've always asked guys about their BRs or F-Class rigs. I learned a whole lot really fast. If you wanna pig out on data, man go hang out with BR guys. They've done it all. I just love to go shoot with different people across different disciplines.
My discipline is hunting, so we get a lot of nose turns in our direction for the longest. And with barrel cleaning I don’t unless I know I have a chance prior to the morning of or day of the hunt to make sure we are on target just like when we go to the range. Eric mentions using a alcohol based graphite to fowl the barrel. I must say I have to try it. Other wise my barrel’s normally take 3-4 shots to bring it back. But an un fowled barrel, mirror clean heading out on a field with one solid cold bore shot at best if we are lucky to reload for a second. At least for me I have to know it’s on.
New bullet. 140 eldm. Two days of zero confirmation from 100 yds to 1290 yds. Day three, start at 1317 yds, then go out to 1777 yds. First round impact followed by two more. This done with a magnetospeed on this new load with all shots being recorded for MV’s. Using applied ballistics and their CDM the drag curve was predicted perfectly out to 1777 yds. To do this with bc’s, I would use stepped bc’s which is different bc’s at different distances. For example, a bc out to 400 yds then another around 900 yds and finally a bc in the subsonic region. The CDM’s are absolutely amazing and much easier to use to predict bullet trajectory!!!
Mr Wojcik The reason I don't get excited about the radar derived drag curve is exactly the reason you said: you still have to correct for "different rates of twist, different rifling profiles, different muzzel velocity" etc. The G7 is good enough to get me on the paper: the ONLY data that is actually going to be accurate ultimately is hard dope, and the G7 curve is similar enough to any actual flight profile that I can shuffle it around to fill in the small gaps between my hard dope data points (honestly, one could use a French curve or Excel to fill in the gaps in data points). Radar data is superfluous. It's about as useful as the "Muzzel Velocity" listed on the box.
So just finished listening to the Litz interview and learned they can make you a personal drag model made for your gun and ammo: I'll admit I didn't know that was a thing, and I'm far more excited about that. 10 rounds and you have your curve captured with no fiddling. Next rifle I buy I'm totally doing that!
I don't believe you need to adjust the powder charge when you adjust seating depth. We have always looked at the powder charge as the "coarse" tune for the load, and the seating depth as the "fine" tune. A true OCW charge will have built-in tolerance to the tiny changes in volume that seating depth tuning will induce.
Dan Newberry, so far your OCW method has resulted in the tightest and most consistent groups for me beyond 1000yds. I'd love to hear you and Eric Cortina discuss this topic as I am sure most of us interested in getting better would enjoy that video. I believe everything is "a way" not always the way to do things. I'm always learning and trying to improve through being open to different ideas.
Some cheap advice from a brother in arms,I get powder graphite from Amazon for cheap buy the 2lb jar. Same stuff as lockease. I care about the shooting community, about the people who are friendly and share. When a proshooter tells you there secrets, that is a man who loves to compete. Wish we could be on firing line .
If you have a custom drag model, like an ABS computer app, all you need to do is adjust MV. The bullet flies on that custom drag model's flight path. Forget G-anything. WillyB
Erik- you got the tools... Instead of cleaning with a drill, maybe figure a way to keep the ball bearing handle on the cleaning rod and attach it to a sawzall?
@@BelieveTheTarget You have FAR more XP than I have, but you might have overlooked something here. 280 AI is a SAAMI cartridge now days and there are several companies producing it. As for the quality of said cases, I cannot vouch for that, but you no longer need to fire form it. From your experience, is there anything to be gained or lost by going with the Remington derived 280 AI versus the Winchester derived Shehane? I believe the 280 AI has slightly more cc, but I don't think that is much of an advantage?? The 284 win has the advantage of coming with a steeper shoulder in original form versus the 280 remington.
I’m aware that companies make brass for it, but not the type of quality that we require in competition. As for firefoeming, all brass needs to be fireformed. The brass is short from the factory and must be shot to fit my chamber.
@@jackieonassis7438 SAAMI brass is always undersized so it ALWAYS fits EVERY SAAMI chamber (a "match" chamber is undersized by definition, and thus will not fit SAAMI cartridges on the larger side of the scale: better but not perfect): you always need to fireform and then full length resize using a die that matches your specific chamber.
@@wilfdarr I think The point of the video author's answer to my question is that he did of course know about the available brass and doesn't consider it of high quality. That really cleared up his opinion on the existing production brass for said cartridge. Which answered my initial question and the obvious follow up question. I appreciate the info and opinion he offered. I think the basic info you provided will probably be helpful to some as well. Thanks 👍

Great content.. But i disagree with one thing caylen said. You will not make me believe that if a gun shoots .50 that no matter who behind gun it will do the same..
Your last few "interviews" have had an unbelieveable amount of information that is so valuable for many shooters that have not made it to your level of knowledge. Thank you sir.👍
You HAVE To continue this one. That last few minutes was incredibly interesting.
Caylan at first seemed like he just started shooting yesterday. But once he got going, he is/was very good.
Great pod cast, again, Erik! -Thanks
I vote for a Caylen episode 2 ASAP.
Thanks Erik for another great interview.

Is your 284 wheeler a newer 7 wsm with an ability to seat the bullet out longer?
Anyone who shares the name (kay-Lyn) is going to be an interesting person. what a badass!

Such good information
Eric your buddy Francis Colon does custom drag curves for applied ballistics
Nice. #!!! 😊
I don't believe you need to adjust the powder charge when you adjust seating depth. We have always looked at the powder charge as the "coarse" tune for the load, and the seating depth as the "fine" tune.
A true OCW charge will have built-in tolerance to the tiny changes in volume that seating depth tuning will induce.
Ok
Try a flat base bullet versus a boattail bullet same weight..
I bet your powder charge isn't the same

Erik have you watched the latest Hornady Podcast ? There is some great information in the last episode that’s well worth watching.
Do you guys use abrasive cleaners??
Some cheap advice from a brother in arms,I get powder graphite from Amazon for cheap buy the 2lb jar.

I run small and occasional informal hunter matches and a blown primer would have gotten you a dq and your trip would have been wasted.

Erik, why not a 280 AI versus a Shehane? Wouldn't that eliminate the need for fire forming?
No one makes good 280 AI brass.
And even then, it would still need to be fireformed.

So, where does one find radar drag curves for a given bullet to true ones ballistics?
Hornady ballistic app. Under the 4dof. Applied ballistic also has custom drag curves.
Lapua already published doppler Radar data in the 2000s for the Scenars as well. QTU
