Take things one at a time!
#1 break the barrel in with about 20 to 30 rounds and clean
after every shot for the first 10 shots,Then clean after every
2or 3 shots for the next 10. By then you should feel the bore
#2 Now after a good cleaning Shoot several groups to see if
they group or string (dont worry about the size just the shape)
because a line of hits horizontal or vertical normaly means a
poor stock to action/barrel fit.
#3 If it shoots a round group then all it may need is some load
development.If not go to step #4.
#4 Bed the entire action but leave the tip pressure point.(It can
be removed later) to help align the action during bedding.
#5 Shoot to see if bedding helped ,if not remove the pressure
point and shoot again.with barrel floated .
#6 Only take one step at a time and you may find that it shoots
well with out a lot of work.
#7 At this point it should be just a mater of load development to
get the most out of your rifle.
It sounds like a lot of work but it's worth it to get a good shooting
rifle in the end.
I guarantee 1/2 MOA on all of the custom rifles
that I build and this
is the method that I use because it works for me.
If a factory rifle has a good barrel it can be made to shoot well.
