My first OCW - this was too easy...

[shaggyaggie01]

OK, maybe I cheated...
I started with the best components I could find:

H4350 Powder
Virgin Lapua Brass (.260)
Berger 140 gr Hybrid
Federal 210M Primers
and In This rifle: http://www.snipershide.com/shooting/firearms-sale/244158-wts-hamonds-built-260-a.html#post3059279

Loads per the OCW and Berger's published data:

1. 37.0
2. 37.8
3. 38.6
4. 39.4
5. 40.2
6. 41.0
7. 41.8 - this one I did not do on the first trip, because I did not read the instructions very well.

COAL = 2.846"

first outing:

After seeing that there were not 3 in a row, I went back and read the instructions... oops, I figured the OCW was most likely 41.0, but in order to prove it, I loaded three more:

1. 40.2
2.41.0
3.41.8

also, so I would have something else to do at the range, I started on COAL trials for 41.0:

1. 2.836
2. 2.826
3. 2.816

Results:

now, I distinctly remember firing 3 shots at target 2. I wouldn't believe it either.


feel free to let me know what you think. this was fun, I will have to do it for the rest of my rifles.

Hey nice rifle you got there! Seems to shoot well too! Keep looking, you might find a good load. Lol

Seems that .8 gr is a big jump between loads. I typically come up with .3gr difference.

Hmm. It seems I may have read the instructions wrong still... I should have only went back 7% and used a 1% jump... which would put me using a .4 jump. Coming up from about 40 grains. Dangit.

Well that gives me something to do next weekend. It will be interesting to see how much the results will vary.

My best loads for my 26" DTA barrel is 43.3 gr. H4350 in Lapua or Nosler brass using Lapua 139 gr. Senar BTHP. Shooting yesterday suppressed-first shot high, but the final four touching at 100 yds. Haven't uploaded my pictures from yesterday to Photobucket yet, but will do that in the next few days. I need to anneal and FLS after every 3-4 firings. I think your rifle can do even better!

re-do.
1) 40.0
2) 40.4
3) 40.8
4) 41.2
5) 41.6
6)42.0
7) 42.4
8)42.8

looks like #4 to the naked eye, but I plotted them and #7 barely wins.

planned on doing another with the scenars, but ran out of daylight on the range.
