Load data for 75gr .223 for 1:8 twist barrel

[grovey]

This is why I don't ask for information on this board now. Lack of details, like, I am using extended mags, do not load to standard magazine length, could very well cause someone (a new or inexperienced loader) to have some significant and possibly dangerous pressure issues. My advice to anyone reading this is, trust nobody but yourself and double check everything against known standards. Very good information to be found in this forum. Just as much crap that could get you hurt.

That's quite the condescending attitude you've picked up since you were here asking for advice getting started reloading 3 or 4 months back. The OP didn't mention magazine constrictions as an issue. I feel that most of the advice you get here will be based on a bolt gun unless otherwise noted. IMO no one should be reloading without a way to measure where a bullet is in relationship to the lands. Same thing goes for headspace.... There are cheap tools available to check all of this. Also, any load data provided by someone else should be approached by working up to it. ALWAYS!

Alot of things come into play including where the bullet sets both in the case and closeness to the lands, differences in case capacity, chamber size, shoulder bump, bore size, primer, temperature , different powder lots, ETC, ETC.... Point being load data should never be taken as a blanket statement of one size fits all, and most guys here know that.

Your points are well taken, and thank you. I am not new to reloading, just many years since I had and was looking for advice on what had changed a few months back. Most things have not, and I am enjoying being back in it. My issue with many of the posts I read is a lack of explanation or understanding of the OP's question. People are quick to respond with what they use and present it as fact. Truth is, there are so many factors involved, there are few hard truths when it comes to reloading. The guy posting to find a MOA load at 2,3,400 yards does not need to use the same process as a 1000 yard bench rest shooter looking for a one hole group. Also agreed that nobody should be reloading without understanding the process, but when someone says to load magazine length with a near max load with a bullet that is not designed to be loaded at standard magazine length, someone reading and looking for an answer on this board could find themselves in trouble. Their fault for not checking the info, but not everyone looks beyond the obvious. Like I said, a lot of great information on here. Some not so much.

Ball powder ? H-335 and W-748 are my favorite.

You can find data for both on the Hodgdon site.

I like 23.4 grains of 8208 for my loads in a bolt gun with a 24 inch barrel.

Every post on this board is opinion, and may be what works best in that posters gun or may fit the requested parameters. I use varget but that was not desirable, so I recommend TAC. It meters like a dream. The best answers have all the facts, which almost always develop during the posts. My loads are single shot out of a shilen barrel and savage action. That tells you some but distance to the lands, velocity, total length and other factors matter like twist. Dont get mad at people trying to help unless you know it's bad or unsafe data.

I had no issue with your post. Distance to lands, does not change chamber pressure. Total Length does. The post I did have issue with was edited by the poster, and is also not an issue for me in its present form. 25gr of CFE-223 with a 75Gr Hornady ELD loaded to 2.260 was in my opinion a poor place to start and work up from. Maybe I am just too conservative, but the 75gr is not designed to be loaded at 2.26 from my references. Your experience may be different. Many apologies if I offended anyone. Just trying to keep people safe.

23.2 H4895.

I went to hodgen web site match bullet weight to powders. For 70gr H4895 wasn’t recommended.

 

[Robert Juidici]

The ELD is a pizz poor excuse for a match bullet, so if you're serious I'd look past the cheap price and buy a better bullet. Varget for anything in the .223.

Pizz poor? This is at 300 yds. The 600 yard group was .5 MOA. Aero Lower and 18 inch BA Hanson profile SS barrel. Single load CBTO 1.937' F Class mainly.

 

[10XSHOOTER]

24.1 of Varget or RL-15. With 75-77 gr bullets. 24.5 if you moly bullets

Yep, since you're yanking my chain.... 1/2 moa is pizz poor in my book for serious match work. Your book may be easier to read, and have more pictures than mine though.

Distance to lands, does not change chamber pressure. Total Length does.

Please remember that when the bullet is jammed into the lands, it does cause pressure to spike.

 

[skeeljc]

My 1 in 8 twist shoots very well with 24 grains of RL-15 and a Hornady 75 grain HPBT match loaded to 2.25" OAL.

 

[joshb]

“ Distance to lands, does not change chamber pressure. Total Length does.”
??? They’re just two different ways to measure the same value. They have the same affect on pressure. In general terms, shortening Over All Length moves the ogive back, away from the lands. Measuring to the ogive is more accurate because (most often) bullet tips are not the same.
Don’t discount the other effect of moving the bullet deeper in the case, away from the lands: It reduces case volume, which can raise pressure.

Standard service rifle loads have been 23.2gr 8208 or 24gr of RL15 or Varget under a 75/77gr bullet (not including amax) in LC brass. These generally all shoot really well and require minimal tweaking for your rifle.

 

[LVLAaron]

24g RL15 seated to mag length. Very common load for the 75/77 class bullets.

 

[Hohn]

New to board. I’ve been having difficulty locating load data for 223 in 75gr. Open to suggestions. Was looking at using Hornady ELD 75gr and RL 15, however I’ve not made up my mind.

Load data for the 223 is everywhere. I suggest you improve your resourcefulness. Hornady publishes both hard copy and ebook copies of their data, alliiant has free PDF, Nosler and Speer both post free data online, Hodgdon posts it free online too.

If you are having difficulty finding .223 data you either aren’t trying much at all, or don’t know the basics of internet use.

He might have learned something in the last two years since this post was made. You will forever be an ass it would appear.

Yet ironically I gave him more help than you did. Who’s the ass now?

Appears to be confirmed. But, hey, only your opinion counts.

“when someone says to load magazine length with a near max load with a bullet that is not designed to be loaded at standard magazine length,”

I may have missed it. Can you tell me about these bullets that aren’t “designed” to be loaded at mag length. I just looked thru my Hornady and Berger books and I can’t seem to find any.
