Re: berger 300gr 338 bullet accuracy nodes
3050 wow!! The old design had problems with nose slump at high velocity. But that's supposed to be fixed on the second gen. Do you know which ones you have? It's prolly more likely the rifle didn't like the load.

I was shooting with him. The rifle is a 338 Rogue. It's LM with less body taper and a 37° shoulder. He chose the load based on this ladder test. I believe the loads were 111.0, 111.5 & 112.0
At 300 yards, the groups had about a 6" vertical with no consistancy (other than they were consistantly bad).

If these are Gen II 300grainers the speed your sending them at isn't the problem. Guys with 408 based 338's are sending them down range well over 3200 without problems. I would say you have something in your recipe that your gun doesn't like.

They are Gen II's. Is there a known node between 2900 and 3200fps?

Re: berger 300gr 338 bullet accuracy nodes
Berger bullets typically like 0-10 thou off the lands and you could be trying to drive them a bit to hard for YOUR gun. Back it down a little and play with your seating depth and you may find something it likes.
How well does your gun shoot the 300 SMK???

Re: berger 300gr 338 bullet accuracy nodes
My Ex 700p in Lapua Imp shot the 300 Scenars & shoots the GenIIs really well at 3050-3100 with 1-10 barrel.
I would say you have a seating depth issue.
They also shoot really well in my Norma at 2780-2850 & Edges at 2850-2950.

Kiwi greg- what powder are you using? </div></div>
Currently N570 as it gave slightly more speed than Retumbo with the Scenars.
When I use up the rest of my N570 I will change to Retumbo.
I have a 33.5" barrel which may account for some of the speed

Check torque on stock/receiver bolts, scope mount torqued and secure?
I'd make twin loads for each pwd wgt charge and try again(help remove some doubt), going no higher than 109. @ 109 you wrote hard bolt lift on the target.

Re: berger 300gr 338 bullet accuracy nodes
The load with 109 must of been a bad piece of brass it was the only hard bolt lift and I am going to take out some loads and try them at different seating depths if that don't work then I will slow them down. Thanks for therefore input!!
