25 Creed Load data

[Gaddyman]

Just built a 25 Creed. Thought Id share some of the results.

Specs:
Tikka Action
Carbon six 7.5 twist 24inch
MDT XRS
MDT metal AICS mags without the feeder due to COAL

I started with a ladder test of 2 dif powders in .1 increments.
Here is ramshot hunter 43.7gn- 47gn


H4350: 41.6 gn- 43.6gn



I shot each powder at one target and then picked between the two which one looked most consistent and referenced my data: See attached photos

H4350 FPS
1.
2. 2809.8
3. 2832.4
4. 2849.5
5. 2852.9
6. 2887.0
7. 2916.4
8. 2933.5
9. 2931.8
10. 2964.3
11. 2963.6
12. 2995.2
13. 3002.7
14. 3018.1
15. 3046.1
16. 3057.2
17. 3056.8
18. 3076.5
19. 3102.5
20. 3006.7

Ramshot:

1. 2822.6
2.
3. 2854.2
4. 2826.7
5. 2845.3
6. 2857.7
7. 2877.5
8. 2901.6
9. 2913.6
10. 2945.6
11. 2953.6
12. 2984.4
13. 3011.7
14. 3029.2
15. 3047.0
16. 3062.6
17. 3086.6

Then i tested the ones that seemed to have the same POI

and oh boy be carefull doing a ladder test when its colder lol

I was getting 120-160 fps more in my second test.
but SD and ES were good and all the groups were sub MOA except for 2 that had one flyer each.
45.9 ramshot 3 same hole 9 clock | Shots: 3 | Avg: 3005.6 | SD: 4.2

Ramshot 45.7 | Shots: 3 | Avg: 2985.5 | SD: 6.0

H42.0 | Shots: 3 | Avg: 2996.3 | SD: 8.5

H41.8 | Shots: 3 | Avg: 2975.6 | SD: 6.9

H41.6 2 same hole one all 3 | Shots: 3 | Avg: 2962.8 | SD: 1.2

H42.6 | Shots: 3 | Avg: 3064.1 | SD: 3.9

H42.4 | Shots: 3 | Avg: 3019.5 | SD: 2.4

What bullet?

 

[Walker6]

What Ramshot?

Hunter.. Missed that at first glance.

 

[Hoghead]

COL also please.

 

[Gaddyman]

COL also please.

2.892

Clearly you put alot of effort into it, but im not following what exactly you did.

Are the listed 20 h4350 and 17 hunter fps numbers individual shots at .1 grain powder charge increments?

Then you chose some for 3 shot groups?

I guess im not making the decision making connection between the two. Or the reasons for shooting one shot at .1gr intervals across such a spread.

Ultimately what did you decide for load recipes?

Also. The 120-160 fps difference on your 2nd test, what was the rough temperature difference and was that with both powders or just ramshot hunter? That tidbit is interesting.

Sorry Lol i wrote this while at work.

115 MTH cutting edge bullet.

No worries @Walker6

@streamerfish

This is how i test my loads and ill explain it alot better now that im on the computer and have time:

I start with a charge range and i typically decide on 1 type of bullet and brass and primmer.

I will then select 3-5 powders and get a range of charge weights for each one. So for this test for Ex I only had 3 powders around so i only tested Ramshot hunter and H4350 and 6.5 staball (Ill explain why i didnt mention staball).

I will then take those ranges normally .2 incerments and shoot each powder at there own target. One shot for each charge weight. From this i get a couple data points. One it shows me which powders are gonna be the most forgiving. What i mean by this is if the POI on the diff charge weights are all roughly grouping well ish Ik that it will be an easy load to develop with that powder. Ull be shocked at how well it works. When you test powders instead of bullets it changes the game. It also gives me a rough idea of my nodes for velocity. Not perfect but it works pretty well.

From then Ill test my winning powder and do a typical ladder test with that one powder and shoot a range that is within the velocity i like and from the FPS data i have from the first test. ill see where either A it dipped down in velocity even when it was a higher charge weight or the FPS was close to the previous and the following one.
When doing this test i dont care about groups i care more about POI. I see where relative to a clock it hits and ill normally narrow it down to a 3 charge weight range. Then ill fine tune the load and bam done.

FYI i dont not change my scope this entire test. I clean the gun once before the test and thats it. Ill clean it when im done and just double check my load.

This i found gives me a super forgiving load. I mean i can have a SD of 20 and still being hitting the same place. Temp doesnt matter after that, elevation is more forgiving some what and if i mess up a charge weight by .1, ik that my load is still gonna have the same POI.

For the temp during the test heres the interesting part. My first test was 55F out with a higher RH. When i tested it later it was 80 with a lower RH. I was getting pressure signs wayyy earlier then i thought so i stopped.
The 17 shots and 20 shots was kinda funny. I stopped bc i got pressure signs on one and the other I loaded a bunch of lower charge loads on accident realizing I had inputted 110 grn bullets not 115 grn bullets so i had to pull a couple of the super low ones and just restart.

Peterson brass. LRP. I ended up with actually going with the 44 grns of ramshot hunter. I am planning on doing my dope soon for it. I did this method with my 280 ai and it worked great. I gotta give credit to little crow gun works for his method. it works great.

 

[Gaddyman]

Forgot to say with the staball 6.5, the reason i didn't include it was bc i was getting horrible groups with it during my ladder test. It also was a pain to meter in my scale for some reason it had a hard time learning that powder but not my ramshot. weird. But with the final load i had an avg FPS of 2850 and was getting .3 to .2 moa at 100 yards with that lower load. Dont have to burn my barrel out in those higher loads anyway. My SD was 2.4 for the final load with an ES of if i remember correctly like 8

 

[streamerfish]

Gotcha.

Yeah, im with you on changing powder, or bullet to affect real change.

The rest...way too much white noise for me. Im the opposite in a way, if your method is a wide and shallow net (lots of small variable changes with few shots per variable, Im more of a narrow, deep net (couple big variable changes, more shots per variable to get relevant sample sizes).

But to each their own.

On the 6.5 staball, were you using some kind of electronic powder drop and it didn't like the pellet shape or something? I dont use them, didn't know that had potential issues like that.

Hoping some staball 6.5 shows up locally here sometime, looking forward to testing it out.

an rcbs master scale. and i never change bullet once i chose one. unless i see it on an animal preform in a way i dont like.

it was a great powder in my 280ai but it is not as temp insensitive as people think. plus iv noticed if im not in the 95% range of case capacity with it. it does not do well.
