How much h335 for 55gr hp?

[Mohave-Tec]

I have a precision round that works great in both my Savage 223 and my AR. Being new to the AR-15 I am developing a range round for the 223. I'm almost as interested in an efficient and time effective reloading process, for this range round, as I am for any real accuracy. I'm doing this on a Lee Classic Press so I'm wanting to use H335 for its fluid measuring characteristics. I'm using Remington Power-Lokt 55gr HP bullets because I have a bizzilion of them. How much H335 for this round? I'm not finding anything specific. I'd love to have a better idea of low and high loads if anybody has a suggestions. Thanks a bunch!
I have 8 manuals. Jeeeez.

Hodgdon lists the Speer 55 grain SP.

Use that data.

Start at the Start load (23.0) and work up to Max, (if you want to go that far), as normal when working up any load for any bullet.

Hodgdon has some online data.

My bullets are a cannielured hollow point. I saw the Speer/Hodgdon data but didn't want to trust the two bullets were similar enough. I'll try it.
Since I don't have the bench space for a progressive I am trying to make my little Lee Turret load process as efficient as possible so for range rounds I chose h335 because it is as fluid as water. I'm also hoping that the 1.57cc auto loaded (=24.2gr H335) with be the sweet spot. Right now I'm loading 5 of each starting at 23gr in increments of ,2grs but I'm loading 20 of the easy loading 1.57cc and testing for speed and testing for accuracy. I'd still love to know what Remington is calling the specific high and low for this powder and this bullet. Why so little data on big'ol Remington?

Walkalong, but they don't have my bullet or anything close enough to give me a warm fuzzy feeling.

Because Remington has never ever published any reloading data.

Those that do publish data are usually bullet manufactures, and they only publish data for their own brand of bullets.

Or powder manufactures, who often don't tell you what brand 55 grain bullet they used.

The only two exceptions are Lyman, and Hodgdon.
And they both tested Speer 55 grain SP's for whatever reason.

They can't test every bullet ever made.

A 55 grain bullet is a 55 grain bullet-----unless it is a solid or frangible. There are minor seating depth differences when using a boat tailed or soft point/FMJ. But not enough to worry about unless at MAX load without working up to it. The cannalure on a 223 bullet is of no use to me. I do not crimp my rounds and there is more than enough neck tension to hold them firmly using my Lee dies. FWIW I tried both crimped and uncrimped casings and found the uncrimped ammo shot better in every loading I tried. If you have bullet setback problems then you may need to tighten the neck tension or crimp your ammo and the accuracy MAY be affected a bit. There are some on this forum that say they have more accurate ammo when crimping in the cannalure, I believe them as they have that experience---personally I have not found this to be true in any of MY firearms.YMMV

Then you'll have a tough time being a reloader. As posted, they cannot test everything. As long as the bullet construction is similar (JHP, JHSP,etc, the seating depth is close, you can work up a load. You say you just want an easy to make range load, so you will certainly find something you like before you get to the max load shown with a similar bullet.

I shoot 1000 yards or did until I got older. I've been reloading forever. The tightest group I've ever shot is with a Hornaday 60gr VMax over 25gr Varget. I use a gentle roll crimp just to take the edge off the case mouth. I do that in just about everything.
Well, I've worked up to 25gr of H335; up from 23. I'm hoping like heck this 24.2/24.5 gr H335 will do the trick. I'll know at 7AM tomorrow if it's not already 100 degrees at the range by then.

With a 55 gr Remington Core-Lokt I get great 100 yd performance with 24.2 gr of H-335.

 

[Mohave-Tec]

Well that is good to hear. I have Power-Lokt rather than Core-Lokt but I'm guessing they are as close as I'm going to get since I've actually never seen a Power-Lokt anyplace else but my bench and Midway about 10 years ago. 24.2 is just about what the largest drop I can get from my powder charger without stacking. I will report back tomorrow.

The 55gr Speer soft point tested by Hodgdon sure is close enough your Remington bullet.

I'm loading just off the Max recommended by Hodgdon @25.0gr H335 under a 55gr jacketed bullet for semi-autos. That works very well for me.

In a bolt action rifle the recipe is completely different including primers, powder, bullets and brass.

I do 24.8gr at 2.233" OAL for 55gr FMJBTs. Great load.

Thank you everybody. I am now at least sure I won't blow up the barrel.
I have a 60gr VMAX over 25gr of Varget that is crazy accurate in my Savage that already looks pretty promising for the new AR build but that was on day one with the new AR and off shoulder and off the hood of my car. I'm hoping like heck that can be the go-to round for defense in both rifles but this load is just for crashing around in the desert. H335 makes it much faster to make because of its metering characteristics and the equipment it has. Of coarse I am hoping it is accurate as well.
