Thanks. Going to try and wait to test this when I have a reliable chronograph to shoot through. The initial powder test looked promising but the seating not so much
Erik Cortina said:zfastmalibu said:Eric, How big are those groups after you tune the seating depth, and how much vertical at 1k are they giving you? Have you ever had a gun that did not print like that? My groups tent to follow a sine wave pattern, usually the groups that print highest or lowest (when the barrel is at the end of it whip) will give the least vertical and best groups. I shoot a dasher and find my windows are small, if I load .2 either way the load will get vertical.
Thanks
The groups get down in the .1's and .2's after seating depth tuning. That gives somewhere about 4" - 6" groups at 1,000 yards. During competition, I have shot 198's with this load at 1,000 yards.

I would think a ladder test is easier to see vertical spread rather than OCW target testing because there's no need to discern between center of groups with the ladder test, both seem to get the job done but it's seems reading a target would be easier with a ladder test. Just asking, I'm playing devils advocate because I'm trying to talk myself out of the ladder test, had confusing results last week during mine.
Thanks

Thanks in advance

Thanks

Although they are right in some cases, I like to test at 100 yards so that I can assure that my bullets have settled down at 100 yards. If you can get the bullet to settle down faster, the average BC of the bullet will be higher between muzzle and target.

So during your testing you do the round robin: shoot load 1 at target 1, load 2 at target 2....correct?
Thanks

No, I shoot one group at a time.
Do you have a reason why you don't do the round robin method to spread the loads out over the changing conditions during the test?

Gun is shooting well.

I don't have any chrono numbers. I have a Magnetospeed, but I don't like shooting load development with it attached to the barrel. I'm thinking about chronographing 43.4 gr load and 44.4 gr load. My rifle has a 28" barrel, so both should work for shooting up to 600 yds.
