Default APR 6.5 Creedmoor Load Development

I was able to make it back out to the range today with some handloads to see what they would do. Overall I was pleased and found a good node to play in with the 143 ELD and 40.5-41.5 of H4350. I also took along some 124 grain Hammer Hunters and found a load at 44.5 grains that is promising. That is a hot load though, so I will likely try 44 and see if the accuracy holds. On the recommendation of Steve with Hammer Bullets I also have some Varget to try with those bullets.

I had the ELDX's loaded over 39, 39.5, 40, 40.5, 41, 41.5, 42, and 42.5 of H4350. The groups at 40.5, 41, and 41.5 were .2440, .2470, and .3445. I will load some at 40.5, 40.7, 41, and 41.2 and take them to 300 on the next trip to see where it's at when it comes to longer ranges.

With the H4350 the only problems I noticed were slight ejector marks with the 42.5 loads.

I was pretty disappointed in the 124 Hammer Hunters until I got to the last group at 44.5 grains, which measured .2825, so I will load some more at 44, 44.2, and 44.5 to take to 300 along with some loads over Varget on my next trip. I really want to use these on my mule deer trip in November as well as in Africa next June. I like the design of the solid copper bullet and the extra velocity of the 124 round. My rifle is a 22" 1:8 barrel and the 44.5 rounds averaged 2913 with an ES of 16, compared to the 41 grain ELDX loads at 2603 with an ES of 42. I was a little disappointed with the ES numbers across the board, but I think some of that comes with practice. I haven't reloaded in about 10 years, but was pretty proud of how they performed overall.

You'll notice that some of the targets have 5 rounds, but only 3 measured for the group, that's because I shot 3 shot groups, then went back with a hot barrel to see where the last 2 loads for each were hitting compared to the cold barrel shots.

39 ELDX


39.5 ELDX


40 ELDX


40.5 ELDX


41 ELDX


41.5 ELDX


42 ELDX


42.5 ELDX (slight ejector marks and was also running out of places to aim on the target)


41.5 124 Hammer Hunter


42.5 Hammer Hunter


44.5 Hammer Hunter


Figured I'd throw in a picture of the rifle from tonight with my new patches because let's face it, who doesn't like a picture of a pretty girl!!

5 shot group at 100 yards with 42.0gr H4350. I have a 24 inch barrel and using Rem 7 1/2 primers. I also got better accuracy out of the Sierra 140 than the ELDX.

I weighed 15 of those ELDX bullets and was not very impressed, weight variance was +/- .3 grains which does not amount to anything for hunting. Maybe the batch I got was made on Friday.

Are you guys using brands of brass or what? One is using Lapua brass and small rifle benchrest primers and the other is using large rifle benchrest primers. I'm guessing the Lapua comes in small and large rifle primer configurations?

Yes Lapua brass with small flash hole and small primers. Redding dies are set up for the small flash hole on Lapua brass. I believe it is .060 diameter hole.

Looks like 40 to 41 grains. Someone else had good results from the 140 also.

I'm glad so many guys are narrowing down data when I decide to need it.


This is the first 3 rounds from my alamo man bun after boresite. The flier to the right was me not even being close to ready for the trigger to break. I was ready for the next 2.

143 eldx hornady

Question to the OP, on your targets your drawing a box or circle around what appears to be some of the shots that are really close together but there are others in the group that would bring your measurement way up. Why are you not including those? Are they called fliers or you just like to think your groups are better than they really are? Or maybe I've just been doing it wrong all this time.

Pretty good.

I prefer to roll my own and making my own arrows. Probably a heck of a lot cheaper buying store bought stuff.

I was wondering about that also.

I shot 3 shots of each, which are the boxed groups. I then went back with a hot barrel and rushed through shooting the other 2 shots I had loaded for each powder level to see where they were hitting out of a hot barrel and mainly because I needed the brass to try some other loads and wanted to get the bullets out of them. Some of the targets I also shot at different aiming points on the last 2.

A couple of the groups would’ve actually been smaller if I was just picking the best 3.

I normally would’ve done 5 shot groups at each, but was short on time since I had to pick my son up and get him to baseball practice

Mine likes the 140 Hornady Black ammo as well. That flyer was a first shot after cleaning the rifle. The next 5 made that group which were shots 7-11 out of the rifle

I'm just picking at you. That is one fine shooting rifle and I'm really mad at myself for not getting in on the group buy.

My LaRue 6.5CM likes the Hornady Black. I've never shot it out of the APR bolt gun but I will now! Nice group!

Take a look at RL-26. One of my creedmoors loves it. In the other, 42.5 of H4350 does the trick.

I can’t get 42.5gr of h4350, too hot. Yes RL26 has some horsepower, I got up to 2900 FPS with it and no pressure signs with 140gr boolits. Unfortunately the groups were not impressive.

I tried RL26 with the 124’s and groups were subpar. I have some RL16 and varget that I’ll load this weekend and hopefully squeeze in another range trip this week

This will be my last post about the 6.5 CM that APR built for me. I finally got a good load worked up that should work in other rifles or at least a reference point to start from.

Brass is Lapua brand with small primer pockets and small flash hole, full length sized.

Bullets are 140 grain Sierra SPT Gamekings seated at .008 from lands.

Powder is Hogdon H4350 using 42.0 grains

Primers are CCI BR4

Velocity is 2730 FPS, an Extreme Spread(ES) of 11 and a Standard Deviation(SD) of 5.

I tried several Nosler, Berger and Hornady bullets but kept coming back to the Sierras. Also tried RL17 and RL26 powders but H4350 was better. I can also say that groups shot at a 100 yards really do not do the cartridge justice, it gotta be 200 yards or more to actually see any difference. Today while shooting conditions were good, I got my sight settings up to 375 yards.
I had 4 loaded rounds left and decided to put a new target and shoot four for score. This is a picture of a 4 shot group at 375 yards. Probably as good as it gets. P.S. I reckon that no Man Bun growed on my head during this project.
