Gun is ready for the range.  I have 190's 200's and 210 loaded and ready.  Now to figure out what bullet and load it likes.

Good Luck !  3 bullets x 10 loads x 5 seating depths then move out 300 yards and adjust and repeat    hehe     Enjoy the journey

75 bullets loaded with .5 grain incremets 3 bullet weights.  This is a solid 6 hour range day in and of itself......guess I will pack a lunch.  In my experience, I wll know what the gun likes by the end of this day.  Then I can fine tune with .2 grain increments and playing with seating depth.  The problem comes when it shoots multiple bullets loads well.....then I have to start making decisions.

What components are you using?

What components are you using?

Nosler brass, Federal 215 primers, H1000 powder. Trying Nosler 190 gr and 210 gr ABLR AND 200 gr AB's.

you poor poor man  Those ABLR are amazing performers on game but gosh dang are they finicky to load

Those stinking ABLR . Lost sleep trying to get them to run hard and accurate.

I ended up getting more out of the 215 Berger Hybrids than the 190s and it wasn’t close.

Why do you think they are so finicy......first time loading the ablr so any insight may be helpful.

They are very sensitive to seating depth and powder charge. Very narrow accuracy nodes in my experience.
I worked with 190s in a 300 win and got them shooting pretty well then tried 215 bergers and the same powder charge and bto measurement shot with equal accuracy and 50 fps slower.
I’ve tried them in a few guns and always had a rough time getting good results, when other bullets were easy to get shooting well.
I’ve read a couple things online that the ablr like long jumps and faster burning powders but haven’t messed with them enough to confirm.

I'll echo the long jumps.  My wife's .270 WSM couldn't get near the lands while still fitting the magazine.  I was nervous about it, having come from Bergers which typically like being right on or near the lands.  Ended up finding a sweat heart load that shot clover leaves at 200.  That load was for the 150 grainers.  It did use a slower powder though, H-1000.

As has been echoed by others they are very sensitive to seating depth.  I've loaded them in 4 different chambers and all too quite a few rounds to find that money spot.  Like I said before, they are straight killers if you can get them to shoot.  I really wanted them to work in my main  hunting rig but I couldn't find the money shot at a velocity I was happy with.  BC was inflated 10% as well.

Live and learn. Pick a bullet and work it out. If it doesn’t perform, choose the next and work it out.

Holy smokes! I don't think I've ever spent that much effort trying to get a bullet to shoot.

I was pretty happy with the 200gr AB in my 300 Win Mag. I just crunched a case full of Retumbo under the AB at mag length and it shot right around .75 MOA, good enough to hit an MOA sized target out to 800 yards.

When it comes to the .300 Winchester. Seating depth is the least of you worries. The .300 is very forgiving when it comes to seating depth.

As much as finding a great shooting round.....this is equally about trigger time and experimenting.  I anticipate I will find a shooter in each of the three tested loads.  Then I will chrono each and decide which one I like based on ballistic data.  Then I can fine tune from there......All the mean while I will be getting plenty of trigger time. 

Usually I have a bullet weight picked out and a caliber I am very familiar with.  In this case, I am not overly familiar with the caliber so might as well play.
