[ARCHIVED THREAD] - Looking for a 55 grain H335 plinking load.

Posted: 1/20/2019 1:12:23 PM EDT

Something not too hot or weak: using LC Brass and M193 bullets.

Thanks

I trust Hodgdon's data for 55 fmj and H335 powder. I would consider 25 grains as the top load with a starting charge at 23.5. A good load that does well is 24.0-24.5 grains. M193 bullets have long sharp points and the overall length should be around 2.250" and not longer. I use RP 7 1/2 primers in my loads.

24.5 grains of H335 is reasonable and not too hot.

Seat the bullets mid cannelure, don't worry about OAL".

You understand proper load development requires starting lower and working up, correct? Simply accepting load data (especially off the web) and using it is a recipe for disaster. People make typo's and remember incorrectly.

Reference the online data posted by Hodgdon, knowing that your exact components are not exacy what they used.

Of course.

I have some data already but the min/ max charges greatly vary.

Just trying to get an idea.

2.245-2.250 is what I usually shoot for using M855 bullets and I was planning on doing the same with these M193.

24.0g H335 under a Hornady 55g fmj is my bulk plinking load. CCI 450 primer, any brand brass.

24gr. H335
Berry's Bullets 55gr bulk.
PMC commercial case. 1x fired.
Sellier & Bellot SRP.
2.240 OAL.

Shoots like a laser out of my nephews 1/9 Stag HB non chrome barrel.

Thanks for all of the replies.

I think I'll start out with 24 grains with CCI 400 primers ( the primers I typically use).

My 3gun hoser load is light.
22.6gr H335
2.245"oal
Very accurate in all my guns.
All of the below groups shot with red dot.

Top right Target

50 yards.

50 yards with 12" pistol. Bottom left target.

10 Rounds @ 200 yards with red dot.
About 5" group

They cycle in all of my rifles.
My general H335 load is 25gr, but not as accurate.

So the work yourself. What works for others may not work for you. DO YOUR OWN LOAD DEVELOPMENT so you have the best accuracy with reliability & safety for you guns!

I'm just looking for good starting point.. From there I'll tweak it.

This. I ended up at 24.7 as that was where my powder measure was throwing the most consistent charges. 24-25gr should get you in the sweet spot. I load to get a good crimp mid-canellure.

Posted: 1/21/2019 12:52:10 AM EDT

[#12]

I worked up from 23gr to 26 in .5 increments

I had two nodes of under 1moa in both of my 16 inch Intermediate Gas - Rainier Arms Ultramatch MOD2 barrels

23.5 @ 2510fps and 25.0 @ 2805fps

Lake City Brass, WSR Primer, 55gr FMJ Hornady @ 2.240 OAL

I ended up going with 25.0 for my 3gun hoser load for up to 200 yard work as I felt it shot and worked my comp very well. Recoil is not much different.

Posted: 1/22/2019 10:04:21 PM EDT

My plinking load is 24.5gr with 55gr soft points. 2,893 fps from a 16” barrel.

Posted: 1/23/2019 3:11:56 AM EDT

[#14]

It's very likely you can find 2 accuracy nodes between 22 and 25 grains. Since we rarely "plink" at more than 200 yards I chose the one that uses less powder.

Watch your primers for flattening. I had CCI 400's flatten out at 24.0g of H335.

CCI 450's don't flatten out like the 400's did due to the slightly thicker cup on the 450's.

The 450's will also have an easier time lighting ball powder especially in cold weather.

Understood.

That said, I have personally never had an ignition problem using CCI 400 primers.

I don't think I own any CCI 450s; although I may have a few.

I do have a shitload of WSR Primers that are supposed to be good for anything.

I did a side by side comparison using CCI-400 and CCI-450. 55gr bullets and WC-844 powder.

I went from 22 to 25.5 gr in half grain increments.

The fired primers all looked the same. In fact some of the 450s looked flatter than the 400s with the same powder charge.

After mixing the fired casings you couldn't tell them apart.

I really don't know what the fuss is about flat primers. Most small rifle primers are going to flatten more than what we are used to seeing in large rifle.

"Reading" small rifle primers has widely been accepted as being meaningless by itself.

As long as I'm within published data and everything else checks out, I could not care less about how flat my small rifle primers are.

If I was a troll I could post photos of thousands of fired casings with flat primers and have everyone here screaming to back the load off and every photo is of a factory loaded cartridge.

I bought some S&B primers recently and after seating some realized there’s no way I’d be able to tell if they were overly flattened after firing. The edges of the cup aren’t rounded at all.

Posted: 1/24/2019 2:10:30 AM EDT

[#19]

24.5g H335
LC Mixed Brass or Hornady Brass
CCI 450
2.20”
Hornady FMJ 55g

That is my standard load for 3 gun and all around shooting.

It is not the most accurate for any individual rifle, but it performs well in all of my rifles.

I loaded up a couple hundred for my rifles, using 25gr H335 and Wolf primers, and accuracy was less than impressive. Granted, I didn't try it in my more accurate rifles, but I don't expect it would have been much better. That being said, I don't think it was a function of the powder or primers...I think the bullets I am loading are simply not that accurate. They were some unmarked/bulk bullets I had picked up, so I will likely try some Hornady next.

Hornady 55gr, and especially the soft-point (in my opinion) are head and shoulders above others in accuracy. Very consistent and well-made. I was at a range a few weeks ago that had steel targets at 300 and 400 yards, and I was hitting them consistently with 55gr SP out of my precision AR.

Posted: 1/28/2019 12:01:34 AM EDT

[#22]

At a minimum use 24.5 grains of H335 (I like 25 grains) and a Hornady 55 grain soft point loaded out almost as far as the AR magazine will allow. I like to go out to 2.245". Max is 2.260.

This is the exact load I use for plinking.

I've loaded thousands of them and still have an unopen 6k box left to load.

My rifles enjoy 24.3 grains.

h335 24.3 works with 62gr for my Car-15 clone, shoots 1" group at 50yds with a red dot, but opens up to 2 1/2" with Hornady 73gr ELD, 11 1/2" barrel, why?

Does it have a 1/12 twist barrel?
