Hornady load data

[1-cavediver]

Greetings. I just picked up two boxes of 145 grain Hornady .270 Win ELD-X bullets. None of my manuals list this projectile so I’m looking for some help. I always use H4831SC for all my .270 loads and I want to stay with it. Could someone provide me with the book minimum and max load for it? I’m guessing around 58-59 grains max but I’d like to see what Hornady publishes. Also, what is the tested OACL?
Thanks!!

#11 has 53.0 min and 59.9 max. 3.330 as oal. That’s not sc, just H4831.

H4831 and H4831sc use the exact load data.

That 59.9 gr is going to definitely be a compressed load. Thanks very much for the data, it’s exactly what I needed.

It's a few .1s off my current 130 grn NAB load and close to Jack O'Conner's original load. I get over 3170 from it with a 24" barrel and sub MOA.

I'm kind of surprised that Speer went that high with a 145grn.

I use a 10" drop tube with slow pour to get it in without excessive "crunching".

I’ve been using one of Jack’s loads since 1973, 57 grains of H4831 under 150 grain Nosler Partitions and magnum primers (except now I use 150 Accubonds). It has served me very well all these years.

Indeed! My .270 Win load for years has been 57.0gr of H4831 and 150gr Hornady Interlock. It certainly works.

I clearly didn’t ask for a photo of a page from the Hornady manual, I just asked for the minimum and maximum load for one specific powder and bullet. There were no copyright issues involved.

Easy peezy, exclude the high and low and load the overlapping mid charge. 58.55
These are 140 AB H4831sc so drop your charge slightly and have a look.

I deleted the pic that was posted, had nothing to do with your request, my bad for not making that clear..

That load is max at 3000 fps but it is not listed as compressed. No “c”. It is an extruded powder that takes up case space. I think as an experiment if you tap the case lightly a few times, it will settle. That’s what it’ll look like after being jostled around a bit.

My experience is that compressed powder leaves little doubt that it will be compressed. Maybe lightly compressed is what this could be considered. Regardless, it will use most of the case volume which is good for accuracy.

I sometime get powder way up in the case neck and I’ll just gently tap it down before seating a bullet. I’ve do this in the bullet trays, just tap the trays with the plastic side of a gunsmith hammer. You don’t have to settle powder. It’s just a quick step I use to get my necks clear.

My fault. Didn’t realize the rules have changed

My son has been shooting them in his Model 70, for a couple of years. We found 57 grains to be an excellent load just over 2800fps. Higher velocity tends to make erratic grouping. I assume its due to the longer projectile.
Hornady #11 changed the COL to 3.330 from the previous edition of 3.210. We have found that 3.310 COL will create nice sub MOA.

I wondered about that a while back when I essentially asked for and received a picture of a page. Should’ve known better. Won’t do that again.

Have it PM’d to you……
We wouldn’t want to bend the rules now, would we…..!?!?…..

 

[Thomasss]

Correct me if I'm wrong but I thought providing information for educational use was an exception. And modifying "artwork" by 10% was also allowable. "We" are not displaying anything in its original form and surely not trying to sell it or under mine its original intent. n'es pas?

 

[Walkalong]

Regardless, please do not share pucs of reloading manuals in public. Privately? How would anyone know.

I also understand the old, but they want you using it to use their product argument as well, but copyright issues are a huge deal these days, it can get a forum shut down, or worse.

Thanks

Any copyright lawyers out there? Admin might like to hear from you. Dunno

1-cavediver: Can you please clarify whether you were referring to H4831 or H4831sc? I have a .270 I’m loading for, but haven’t tried either of those yet. H4831 seems hard to find , but I am seeing some availability for H4831sc.

Hi KS Plinker, I replied to your DM in more detail but the short answer is that H4831 and H4831SC are the exact same powder and use the exact same load data. Same velocities and same accuracy. SC just stands for “short cut”, meaning the extrusions are cut shorter allowing for better metering in powder measures. I use the exact same load today as I did in the early 70’s. I haven’t seen the old H4831 on the shelves in several years but then again I don’t look for it because I prefer the SC version for its better metering qualities.
