Actually, I donít have to decide any time soon, but sooner or later I will. I decided to shoot the 260 and 223 today. Both shot little groups right where they should, so I have no complaint. But, I remembered that I had a box of 223 rounds with two different powder charges behind the same bullet - 40 gr Nosler BT. Now would be a good time to see which shot better. No wind and I havenít had much coffee. I had some loads with 26.9 gr of H335 and some with whatís my standard load of 26.3 gr of H335. The 26.9 gr loads shot into a tiny (unmeasured) group in the middle of the bullseye. Hmmm, maybe I should go to that load, but test the other load too. And the 26.3 gr loads shot into a tiny little group (different bullseye) at the same place on that bullseye. Two good loads are better than one, but which should be the chosen load next time I load up ammo? Should I go with the hotter load, or stay with the milder load for hopefully increased brass life?

Brass was Winchester, well prepped, and has been shot a bunch. Still hanging in there though.

Rifle is a Ruger Hawkeye, tuned and rebarreled by Horizon.

IMO, run a 223 as warm as you (safely) can. Brass is plentiful and cheap.

What twist??

My 8 twist bolt gun runs on Varget with a 77 or 69 Sierra SMK or Berger 70gr

My 8 twist AR loves AR Comp and the same bullets as above including the bad azz Nosler 77 RFD

RL-15 is second, no reason to try anymore but I did shoot TAC, Vita Vouri?, 322, 8082,

Can't argue with Chad, because I'm sure he knows a heck of a lot more than me on the subject. I worked with win 748 powder. When I worked up the loads for 55gr. bullet in the 748 powder, I actually found that the most accurate load was toward the mid range of powder range at 24.6 gr. Tested it multiple times same results. I was always confounded until I checked the Nosler manual and it verified my results, saying in 748 the lowest powder charge tested was the most accurate. All that to say, sometimes faster isn't necessarily better.

In your case, it looks like either option would work, so run the faster one. It'll shoot flatter.

Buzzsaw, the rifle twist is a one in 9. I shoot the 40ís for coyote, skunk, armadillo, and such. Iíve switched to 60 gr Partitions for heavier critters. No reason to change powders, since H335 works for all I shoot (40ís, 55ís, 60ís, and 65ís).

The really good thing about this rifle is that it shoots the 40ís and Partitions into the same group, if not the same hole.

Buzzsaw, both of my 223's shoot the 77's Nos CC great with Varget or RL15. One gun is a 7 twist, other is a 8 twist.

According to the Nosler 8th edition manual, W748 was the most accurate powder tested for 40-grain bullets. The most accurate charge of W748 was 28.0 grains (also the max). Other powders tested with 40-grain bullets include Varget, H322, Re7, Alliant "Varmint," H335, IMR 4198, AA 2015, VV N120, and Benchmark.

Oops...somehow I transcribed H335 into W748. Didn't mean to veer off into the weeds...but here I am.

But getting back on track, Nosler's best H335 load with 40-grain bullets was a 27.5 grain charge.

27.5 of H335 was the load I used in the first barrel. The second barrel shows pressure signs at 27, so I canít get to that 27.5 max.

Two loads that shoot well, the hotter load is not over-pressured, shoot the hotter load.

Well I think I would keep the 26.3 and 26.9 targets. Next I would load 26.5 and 26.7. Or at minimum split the difference and load 26.6 and compare. If they shoot another nice tiny group to the same poi, you have 2.2% of your maximum charge weight to imbed your load into. If I found pressure signs at 27 this time of year I would most likely want to drop down a bit more than 26.9 to thwart the possibility of hot summer weather increasing pressure enough that I need to alter the load in the summer months. 0.1 grain of powder is less than four tenths of one percent of your maximum That would likely not be enough buffer to avoid pressure signs on an especially hot summer day, (Particularly if you are in the sun) and cause your load to break down in the summer.

Why not let it be? I don't understand people that find a great load, and want to keep meesing with it. Reproduce it, and go practice!

Last week I ladder tested a powder and bullet I am less familiar with, in an Ackley Improved cartridge, on formed brass. I had to find pressure as well as the powder node I needed to focus on. I accomplished both.

Sunday I group shot three powder charges, and found the winner. Today I will be reproducing that load, and running it out to 800 yards. The remaining loaded rounds will be for practicing and killing coyotes and hogs. Project done.

If you run those two loads out to 300-500 yards you will possibly see a difference in group size. Theoretically the fuller case will give better consistency. Theory does not always play out in practice though as we all know.

I do not agree with that theory. If the fuller case load is actually out of tune with the barrel harmonics, it will shoot poorly. Back to Sunday, I shot three loads for 4X shots (sporter barrel) at 300 yards. The lightest load shot the smallest. That is not the first time that has happened, and it will not be the last.


I do, however, agree with group shooting beyond 100 yards. Chad always does it at 200. I will go 200, or 300, or 500, depending on what rifle I am testing, but 200 yards is my minimum distance. A poor load can shoot decent at 100 yards, at 200+ it will show that it is out of tune.
