Nosler RDF Bullets

[Joe Salt]

Bickering about BC. just makes me laugh. Even if the bullet has 750 BC. and it doesn't work in your rifle, so now you have 1000 or 2000 that don't work. All these Bullet makers are all trying there best to make the magic bullet. So be thankful there all trying. Don't knock them because they don't work in your rifle, or that the BC. isn't high enough or that they got the numbers wrong. I see guys at our range, that are shooting a variety of bullets and in the particular rifles are doing very well. My BC's

On a everyday shooter level, without access to a laboratory of machines and radars. I can only calculate a BC for a given round that will work in my "rifle system".

Going out and shooting will give drops that correlate with the SCOPE/BARREL setup. Using that information I can customize any application to give drops that have been derived from actual field testing, in its given "rifle system".

Weather/Wind gives a measure of unreliable results during field shooting when strictly measuring BC of a bullet. However it will give you extremely useful drop data information of a projectile in the parameters of your "rifle system".

At the end of the day each "rifle system" is different from the next. The scope might track differently through a certain portion of the elevation adjustment vs others. Barrel lands and grooves might in-part a certain degree of jacket deformation that another barrel might not. Along with "true Barrel Twist" might degrade stability of a projectile which in-turn degrades BC. This also works in the opposite direction.

At the end of the day going out and shooting YOUR "Load" in your "rifle system" will give you your "BC for a bullet" that works for you.

I hope this makes sense.

I am looking forward to shooting the Nosler RDF 70 22cal bullets, and the 175gr. Using berger stability calculator, a 1/11 is needed for the 175.

That's about as good as anyone can put it. Really all that matters is what number you come up with based on your system. It may not be the correct BC # based on lab, radar and testing equipment but all that matters is what we come up with while load developing. No numbers that are advertised work perfectly. They always get tuned at the bench each time I load develop a new rifle. Those numbers we look at are simply a baseline of where to begin. Sure, the bigger the number, the more appealing they are. Very well put Eric. Thanks.

Truth

Truth

I find this whole discussion absurd. All I require in a bullets is it is very accurate in my rifle and the bullets are all made to the same size and weight. Since I have never found any mass produced bullets to meet the same size and weight requirement I spend the money to shoot quality custom bullets. EPS in my pair of 6brx's and Hammonds in my 6 PPC. That's what counts on target in matches. This thread like many others sound like one of those theory courses I was required to take many years ago that were of little real value.

 

[eric32]

Your requirements for a bullet might not meet others requirements for a given bullet.

At 100 yards shooting for groups in the .000's custom bullets are IMO the way to go.

While others needs might be a 2 MOA steel plate at 854 yards from a compromised position with no mechanical rest or wind flags.

Its all about needs of a shooter, and his requirements to make hits on targets.

Accuracy has deminishing hit percentage returns on targets after a certain point.

Joe, I agree. This comes to mind whenever I see discussions about BC. "High BC does not always better accuracy. Not sure where I read that but its true. My Hobby is making bullets and although I strive to make all of my bullets higher than normal BC sometimes they wont work for whatever reason. I had a .224 77gr. that was over .4 BC G7. But I needed it to work in an AR service rifle, well if it was loaded at mag length it would fall into the case. it was a disappointment but that's what happens. I have two 6.5x47 rifles, one is a PRS type and the other is a Barnard Prone rifle, although they shoot the same bullet the BC is different. Same twist, same manufacturer, both 5r.The PRS gun has a 25in barrel and the Prone gun has a 30in barrel. Different BC. Don't chase the BC numbers. higher is good but worry about what shoots in your gun. Mike

 

[Park ranger]

A 22 cal bullet that has a G7 of .4???!!! The 80 grain matchking has a g7 of .219 or so. How can this be? I tell ya, service rifle shooters single load at 600, we'd love to have a bullet like that. Seems off....

Bickering over the exact BC might be meaningless to some, especially those who are going to tune to a BC they know. However they have a marketing aspect. Users look at that number, and use it to determine what bullet they might purchase next. So it has value. When a certain bullets advertised BC is more than 7% higher than its actual BC this can influence a purchaser unknowingly.


However tens of thousands of users, use the BC we provide so it is important to be accurate.

 

[rimfiremac]

Wait, your not saying that the BC is published with a marketing intent, are you?

What about the purists?

How will they make decisions now that they know the truth?
How can they be guaranteed to shoot better with less practice?
What do you mean the amax tips never melted in the first place?

And you aren't part of the "marketing"

 

[DocUSMCRetired]

And you aren't part of the "marketing"

We don't publish what would be considered a Marketing BC. Only raw, honest data from us.

Today I got 300 blems in the 105 gr for my 6-284.I measured 100 from base to ogive.

93 at .6655-6665. I am very new at this measuring stuff but, I think(?) that's .001 difference. In this first 100 NONE weighed 105 grs. There was 94 that weighed 104.7 to 104.9. None weighed over 105 grs. The lightest was 104.5. Looking at all 300 bullets I can't figure why they are blems. certainly not from appearance. Pretty well pointed. Tiny, tiny hollow point.

 

[Dgd6mm]

Who's selling blems?

 

[normmatzen]

I got my first two bags of Blems in 105. Loaded up 25 rounds of 6BRX after going to QuickLoad and finding equivalent loads for the shorter base to Ogive dimension of the RDF's. For the same jump my new 3 land X-Caliber barrel tuned for, I added 0.3gr to the original 32.9 gr. The QL MV and barrel time was 5 fps off on MV and right on for barrel time. I am using IMR4320 powder.
I shot a string of 5 shot groups at 600 yd and with the last group
(each group at a different tuner position) I was rewarded by a 2.5" group!
Not record breaking but good enough to warrant more tuning effort with these bullets. My best group prior was 2.675" in this barrel.
After finishing these groups my new barrel has had 189 rounds down the tube.

By the way, I sampled these two bags with 10 of each bag and measured over all length, Base to Ogive as well as weight.

LOA B-O Weight
Avg 1.233" .6625" 105.0gr
SD 0.004 .0009 0.058
ES 0.165 .0035 .370

This means that screening down to near SD values will make the yield very high. And, all you practically need to do is weigh them as the B-O distribution is already tight. Don't forget, these bullets were made with brand new tooling and it is too early to determine how much variation there will be in time.

 

[IdahoSharpshooter]

The reason I tend towards Berger bullets is because I find less variation from lot to lot. It will take two years for Nosler or Hornady, or anybody else to produce enough lots/runs to show the consistency that Berger has.

Shoot the entire 2017 schedule, and report back this time next year. It should be interesting and educational...

[normmatzen]

Rich,

You are absolutely right!
I had a brief love affair with A-MAX's till I started seeing huge variations lot to lot and even within one 100 bullet box! I complained to Hornady and they said my data on dimensional and weight consistencies were within their production limits. Further, he said each lot was tested at 100 yd and must shoot better than 1 MOA! Clearly, they are building for hunters!

I have no experience with Nosler, but I expect to see some erosion in the tooling sooner or later. Only then will we find out if Nosler is, indeed, shooting for the precision long range shooter market.

Who's selling blems?

pro shooters supply

 

[nmkid]

Well, I shot some of the RDF's in my 6-284. New barrel and it's showing a liking for 105 Hybrids and 107 Sierra's. Tried 3 different powders, for a total of 45 RDF's rounds. I could not get any grouping less than 1 3/4" at 100 yards. Don't have the barrel life to go into different primers, seating depths etc. LOL. They are blems...So, I don't know.

 

[normmatzen]

NMkid,

I added a bit of powder to my standard A-MAX load as the base to Ogive was .058 shorter on the RDF compared to the A-MAX when seated for th same jump. As this increased the capacity of the case, I increased the powder charge 0.3 gr to maintain the same Mv and Barrel time (based on QuickLoad). Then my gun was still tuned for that load and shot better than the A-MAX!
