[QUOTE="yorke-1, post: 2459273, member: 11960"] Like I said, the charges surprised me too. I calibrate my scale and verify it with a check weight before every load session. I loaded ammunition for 2 other rifles using known loads on the same day, and those performed exactly as I would expect. I don’t think it’s a issue with my scale. I do use a 6” drop tube for all of my loads and the 96.0gr RL 33charge is slightly compressed. It’s not enough to feel when seating the bullet, but it’s definitely a lightly compressed charge. I’m not hearing crunching or significant resistance when seating bullets though. I don’t plan on pushing the RL 33 load any higher just because the velocity is so far above the norm. I a 300 RUM if I really want to chase velocity. I used a charge of 76.0gr of RL 26 and the same 208gr ELDm bullet while breaking in the barrel, and I was getting about 2760 fps. I chose my RL 26 charges posted here based on what I saw with those initial loads. I’m leaning towards a slightly oversized bore in this barrel. I’ve had this before with different barrels chambered with the same reamer, by the same smith. One would pressure out at a lower powder charge but similar velocity and the other would require slightly more powder to hit the same velocity. [/QUOTE]
