I am getting about 3100 fps out of the 190s with Retumbo at 91.5gr
20 rounds fired and not a single issue. I was firing a 2 rounds then I would let it sit for few minutes and fire other rifles.
About an hour into it I then switched over to the 230 grain rounds. I fired the first round. 3129fps and I couldn't lift the bolt.
3100fps with the 190s and then 3129 with the 230gr round??? I think he had that puppy stoked with 91.5gr of powder, rather than the 86.8 he had been using. Lucky he's able to tell the tale.
