another test gas check vs no gas check

[jsam]

2-2-2014
Today I did a third test of gas check vs no gas check in my Ruger #1 30-30.

If you feel these tests are a waste of time or disagree with my methods I humbly and respectfully encourage you to ignore me. I am as ignorant as the day is long. I am conducting tests for me and no one else. I am not looking for encouragement or direction. I am showing my results because I can. I do this not to teach or inform but because I have often seen people post things like gas checks are a waste of time and money on reduced loads. What I have not seen is raw data of the tests.

I will continue to provide the data from testing and am content for people to draw any conclusions they want. If people conclude that I am a fool who doesn’t know anything I could provide a long list of people who agree with that conclusion.

Saeco 315 with gas check .3095 carnuba red.
12 grains of 4227
Wolf large pistol primer
Average velocity for 10 shots 1208
Es 147
Sd 36

Saeco 316 no gas check .3095 carnuba red
12 grains 4227
Wolf large pistol primer
Average velocity for 10 shots 1204
Es 133
Sd 37
This time the velocity was virtually the same.

When I tested the Saeco 316 sized .3095 lubed with carnuba red with gas check vs sized .3095 lubed with carnuba red no gas check the bullets with no gas checks were 29 fps slower.
Saeco 316 and Lee FP unsized lubed with LLA without gas checks proved to be faster than the same bullets sized .3095 lubed with carnuba red and having a gas check.

I also shot some groups at 100 yards
311466 hollow point with gas checks .310 darr lube
12 grains 4227
Wolf pistol primer Average group size 1.29 3 groups total best group .847
Average velocity 1127
Es 49
Sd 12
Saeco 315 gas checks darr lube
12 grains 4227
Wolf pistol primer Average group size 1.54 3 groups total best group 1.2 inch
Average velocity for 15 shots 1188
Es 63
Sd 18

Tomorrow I plan to test the same bullets with 14 grains 4227.

Keep it up. I find this very interesting.

So how did your non-checked Saeco group compared to the checked version?

[jsam]

I dont want to talk about that.

It was exceptionally bad both with and without gas checks.

Check back tomorrow and if weather allows I will test the saeco 316 sized with and without gas check carnuba red and Saeco 316 unsized with gas check lubed with LLA and unsized lubed with LLA no gas check with 14 grains of 4227.

Good stuff! Good shooting too.

nice to see some raw data not just educated guesses than you for posting

[DrCaveman]

Good stuff! Appreciated here

I can empathize with your 'saeco load' comment. Gotta love it when you do the research, pick what should be a good combo, exercise meticulous care while casting and lubing, checking everythng along the way...then very careful case prep and loading...

Then the pattern looks like a buckshot spray at 40 yds. Ahh the despair...but the hopefulness of the next load being so much better...which it usually is.

Good luck here

"If people conclude that I am a fool who doesn’t know anything...."

Yep, that's why we think, experiment, test, evaluate, re-think and do it over and over. How else are we to learn something of value (to us) and not have to go with 'hot air'.

Go for it and please report.

Good information, maybe I can siphon some of it off for my use.

Thanks,
