Nosler 150 ABLR in 6.5 PRC

[Tcorsini]

Anyone have any information on loading the Nosler 150gr ABLR in 6.5 PRC? Tried several different loads with H1000 and they shot terrible. Some of the newer information that I have seen is saying that these bullets like more jump. Going to try that next but just checking for information since these bullets are so hard to find…

The ABLR is a great bullet design but they are the most finicky on I have ever used. I only have 2 cartridges that will shoot them well out of about 8 I’ve tried them in.

56.4 grains H1000 with a .100 jump shoots well in mine. But 61 grains of Magnum with the same jump shoots even better. .050, .070, and .125 jump all shot awful.

I've had good luck with ABLRs, but have found it takes playing with the seating depth.

I've been trying to find 190 gr ABLRs in .308 for two years. Frustrating...

My mag is .059 from the lands so I'm going to try going out to the .09 to .150 as a test from reading the above comments. Thanks for the info.

If it shot terrible at one seating depth, it will likely shoot terrible at any seating depth. I'd be enlightened to see sufficient and credible evidence proving otherwise, but so would the ballisticians at Hornady and Applied Ballistics.

I don't think that's completely true at all. We all have our own opinions. I know many competitor shooters work in .003 or .006 increments for seating depth. There is a difference and seating depth can make a difference. There's plenty of factors to pick from that can effect accuracy.

Opinion is what you think, fact is what is proven on paper. I can't find a single example of a statistically valid sample size that proves seating depth can improve the accuracy of a given load, but there are thousands of data points from ballisticians that say they don't see those trends. Test it for yourself with a larger sample size, it's an eye opener.

Your fact is your opinion. Thanks for giving your opinion and taking the thread off topic. You are more than welcomed to create your own thread about seating depths. This isn't the help I asked for.

https://rokslide.com/forums/threads/seating-depth-does-it-even-matter.311743/ Here is that thread. I don't think answering a question with a provable point is derailing a thread. YMMV.

I see you're new, might want to poke around and read some threads from other members that have supplied a wealth of knowledge on the subject, before taking a defensive stance.

Painless load development (mine)

I have had multiple people ask me to lay out how I do load development being that what I do is different. Since Shaen @Shooter71 just rebarreled a Tikka 595 in 6XC I thought it would be easy to show how I do it. It’s a Master Sporter with a T3 lite profiled 20” barrel- keep in mind it is a T3...

Your Groups Are Too Small

Thought this was a great discussion about group sizes. Especially chasing a zero. Recommend anyone take a listen.

"I get it. I have a couple rifles I'm at peace with. I have been learning slowly and sometimes you'll keep chasing when it's not going to get there. I just learned that with one of my rifles a couple hundred dollars in bullets later." - your quote from another thread

So, which is it? Seating depth can make a difference and there are plenty of factors that can effect accuracy, or sometimes you'll keep chasing when it's not going to get there?

Seating makes a difference. Going from 1.
25" to just under 3/4" just by adjusting seating depth for me personally. I am referring to chasing a certain number. I am glad you enjoy commenting and trying to ascert your dominance. You don't know everything nor do I.

Not asserting or claiming anything, just repeating results of ballisticians who have legitimately tested the theory.

If you listen to the Hornady podcast they say that in some combos seating depth can make a difference, especially in bullets with a long give length. To state it doesn’t make a difference is ridiculous.

Take a bullet jammed into the lands and then set it 125 thou off and tell me it doesn’t affect group size. Go tell a benchrest guy to seat the bullet anywhere because it doesn’t make a difference.

I've listened to it repetitively, and they say that or chamber geometry MIGHT be a circumstance where it could make a difference, but they haven't seen it proven. It might be ridiculous to you, but there's an 8 page thread I started on the exact subject with 0 posts of valid proof.

Will do, after hunting season. Benchrest guys also use 2 shot "groups" to "tune loads", and use an aggregate to label the precision of their rifles. Since you referenced the Hornady podcast I would assume you understood the statistical variability of sample and group size segment, but apparently not.

I’ve listened to the podcast multiple times and was part of all the threads on here.

So, by your reasoning we can just load a round at any seating depth and it will shoot just as good than any other? No need to test seating depth for anything? From jam to seated really deep will make no difference?

Isn’t an aggregate just an average?

At this point, that's what I believe. Before I became a member I believed in Cortina and all the big shots with their powder charge and seating depth load tuning, but my observations didn't align with what they were saying. Once I found some of the info dumps from Form, and more recently Litz and the Hornady guys, it made sense. I can't find a single documented statistically valid example of different seating depths making a difference on the precision of a load. Even Miles in the video said "I seat my bullet 25-30 thousandths off the lands and forget my seating die is adjustable".

On single yardage matches yes. But that means it shot bigger groups than whatever that average is.

Interesting that he doesn't shoot at .200 off or jammed. I'd like to see someone do 2 20 shot groups where the bullet is seated at jam and .200" off. I'll predict there is a difference in groups. It's funny in their ballistics podcast they talk about how straight the bullet enters the lands is very important to accuracy and at the same time say seating depth doesn't have any affect. The two are tied to each other because, like they said, chambers are very different and some older chamber designs aren't good in that regard.

sorry to the op for the hijack, I'm done.

I shot the Nosler recommended load today, 61.0 grains Magnum with the 150 ABLR's, Fed 210's, new Lapua cases that i should have sized, the necks were way too tight. 7/8" group with the first load tried. 0.050" from the lands. Tried farther from lands and accuracy dropped off. Never tried closer, will next time.
I have never had a load shoot such a different speed than the data said though. Average 2870 fps. 24" barrel, cold (4 Celsius/39 American), 95% humidity, seated far from lands, 800 ft. elevation. I guess it all adds up, but over 200 fps?? Does this sound right? Has anyone had this kind of a variance from a published load? The node was really nice and small, 19fps variance max across 9 shots, plus one outlier. Its got me motivated to tune this load.
