Ended with a 58 and a few X's. Which was a little dissapointing considering I got a nice flat 59 with the VLD's with a switchy tailwind that was throwing everyones shots left and right and up and down later on.


Just to verify the sequency of events here:
    1) Cleaned barrel
    2) borescope
    3) oil patch barrel
    4) 1st detail - 58+?X's - tracking right, no elevation
    5) No clean or oil patch between?
    6) 2nd detail - 59+?X's - no tracking right, no elevation, group shape?

If the sequence is correct, I'd say you lost it with the oil patch.

If the first three steps were instead:
    1) oil patch barrel
    2) Cleaned barrel
    3) borescope


I'd say you left oil in chamber instead.

Can you confirm the sequence?

One thing... second load was fireforming brass with VLD's jammed. First load was formed cases with hybrids jumped. Will be doing the other way round on sunday.

Those 3 points that lead to right hand fliers I have been working on in particular. There is a chance I can do some more 300m testing tomorrow morning as I have to re program some targets.

A follow up today I shot fireforming loads first for a 90.1 from 15 shots. Then shot an 89.7 from 15 shots with the hybrid load. No horizontal apart from one lost shot where the rifle came off the front rest. Still working on technique as that shouldnt have happened, but straight away the horizontal has gone. I guess it shows just what happens when your not consistant during your string. The day was actually scored with 10 shot strings that ended in 120.6X so quite happy with the result. I will do more practice on shooting technique more often I think.
