Accurizing my weatherby

[buckhorn2]

One of thr biggest mistakes is trying to make a gun shoot what you want it to shoot instead of what it likes to shoot. I have wby accumarks and they shoot as well as I can shoot and I use H4831 and accubonds and seat them out as far as I can. I read about barns and other bullets that I wanted to shoot but they diod;nt work in my gun my guns don't shoot partition or flat base either. If they sold bullets in packs of ten ir something like that a guy could try them all. I shoot 79 grains of h4831 it's not a maximum load but shoots great.

I would highly recommend getting a hold of some 215 grain berger hybrids.

They do sell little packs of test bullets, I've ordered them through Sinclair before but different bullets like different powder so I like to make loads with several powders for each bullet. For instance I used to get horrible groups with the Barnes with IMR4831 but with RL19 it shot pretty good, just changing powder made a big difference.

have you tried the e-tip by nosler in 180 gr with 82.5 grams of IMR7828 it shoots with in what you are looking for out of my 300 Whby

Im curious as to how this works out for you. I tried Barnes triple shocks out of my mark V 300 and they did not group well. Accubonds Were much better. Mine is currently at the Shooters Shop getting some work and a load development. I will post up when she is done

I shoot a Mark 5 ultra-light in 300 Win mag.  I started off with groups around 1.5” to 2” at 100yds.  I ended up spending cash and having the action blue printed, barrel free floated, cryo, trigger job, glass bedded.  It has been shooting .5” groups ever sense (last 14 years).  I also picked one up in 25-06 about 9 years ago.  I knew more at that point and glassed it myself, floated the barrel and did the trigger.  Also became a great shooter.   I had many people tell me the ultra-light barrel would not shoot free floated, they were incorrect in both cases.  Try a good glass bed for the action and float barrel, I did glass in under the camber of the barrel.  The trigger is adjustable and worth looking at too. 
I also discovered that the way I was absorbing the recoil was affecting my accuracy with the 300 in the beginning.  It took practice to absorb the recoil consistently with the lighter rifle.   Love the 300 take into the woods every year. 
Good luck

My ultra light is a 270 Winnie shooting hopped up 150 sst's I free floated it I get first two holes touching at 200 then the third is about 3/4 inch high . with the barrel bound I could only guess the third shot would be even higher .
