    308 -Varget Load Testing

    Finally got back to the range. Started from zero again. All cases annealed. All trimmed to same length. All same brand. This is what it produced. Thoughts??

    308 -Varget Load Testing

    10-4. I went back and re-read the whole OCW article on Dan's page. I'm going to run 43.5-45 again and see what happens. I get what he says that MV and ES/SD is not an indication of OCW but.... It's hard to wrap your head around that fact... Off to read Chris long's shockwave pages....

    308 -Varget Load Testing

    10-4 My new plan will be to re-shoot 43.5 - 45.5 in .3 increments without the chrono and see what happens. Will post again after i get those shot.... Thanks for all the help guys.

    308 -Varget Load Testing

    Definitely agree with you. The reason i changed brass mid testing was that the rifle shot poorly after with the 44 charges. I can't attribute that to FC brass. Eventhough, i have heard my people say that FC is hard to work with... I'm pretty sure it was the cleaning and starting with a...

    308 -Varget Load Testing

    I agree with initial data not being all that good. It seemed like big jumps to me as well. However that's what OCW say to do. % wise anyways... So based on that. i shot 44-44.8 in .2 increments. Wouldn't the be small enough increments to show a pattern?

    308 -Varget Load Testing

    Well Professor, ( I love that BTW). I have read it a few times.. The OCW is looking for stability between powder charges, barrel resonance, etc.. In short harmony between components and barrel harmonics... Isn't that what a flat pressure curves show? If all bullets leave the barrel right...

    308 -Varget Load Testing

    Update: 3rd Round of Testing... Built 15 Rounds with Varget 44-44.8 FC annealed brass and Hornady 168 BTHP Match based on the previous MV curves expecting good results... Came back somewhat disappointed. The rifle had been grouping fairly well with factory ammo. On this session that all...

    308 -Varget Load Testing

    Update, Finally made it back to the range last weekend. The kiddos did a little target practice and I managed to shoot 16 Rounds with the chrono attached (after reading the 10 round ocw testing by 6.5 guys). Smaller increments in powder charges this time. 0.3 gr at a time. I graphed the 16...

    308 -Varget Load Testing

    Here is a link to the 6.5 Guys about load testing, MV, ES and SD... Makes a ton on sense..... Good Read Here is an excerpt from it: Next I then load up 5 of the 51.5 grain load and shoot them over the chronograph and the extreme spread was 5 FPS. I have repeated this with H100V, H4350, 4831...

    308 -Varget Load Testing

    I agree that the idea of the OCW is to identify the plateau of the pressure curve. I've been using the magneto speed to record as much data as possible. I'm planning on reshooting 42-47 grains again in .5 increments. I sorted my brass (FC), got it annealed and primed... Ready for powder...

    308 -Varget Load Testing

    Hate to hear that man. I still have high hopes for mine though... Long way from giving up. I like the 6.5 Creed too. I bought my son one. He took his first deer this year with it.. That's next on the list for load development.

    308 -Varget Load Testing

    I’m running a 20” 1:12. The plan is to get the powder sorted out and tune with seating depth. I’ll be running out of the internal mag, so... I’ll be limited there , but we”ll see. ...

    308 -Varget Load Testing

    Greg, Thanks for the reply. I will be loading another test round in .5 increments and give it another go. I like your idea about running the multiple times. Increasing sample size and establishing a true trend.... Good luck with your testing too. That finding a load that shoots great out of...

    308 -Varget Load Testing

    I have most FC, some Hornady, some Win. On this next go around I will sort the cases and see what happens. But, in turn, the amount of rounds won’t be as much. I do t have that much brass (same) accumulated yet.

    It was all once fired from the same chamber. Mixed head stamps though...

    308 -Varget Load Testing

    I get what you are saying. Makes sense. So, when you do your testing, Do you do it in .5 grain increments or something like i did? I don't mind, (rather enjoy it) testing, but at the same time, I would rather not go through 150 rounds of just testing... And yes, I definitely agree with the...

    I have been thinking about the same thing. I believe i will run 5-8 again, just to see...

    308 -Varget Load Testing

    Need a little help deciphering the target. Not sure which load would be best. This is a 308 Win. Rem 700. I may try and re-shoot 10-12. I was starting to feel the recoil. Don't think it mattered since i focused on trigger break and breathing, but still... The MV and SD is hard to exclude...

    "Reading" OCW Targets

    I was thinking of tossing this test and starting it all over again. I agree that even a rock at 50 yards should group better than this. I'll have to make another trip to a range when I'm not so rushed and can take a bit more time shooting. Thanks for all the advice! Will post again with new...

    "Reading" OCW Targets

    No offense taken. Alrighty, so for shooting experience I started as a hand gunner then moved to clays, moved to rifles last year. I've had plenty of experience with triggers and recoil. This particular ar is 16" carbine 5.56 1x9 twist, free floating barrel. Built on dpms lower. A friend let...
