Well yesterday was the calm before the snow storm. Wind was fairly calm so I decided to test out a node with the 22" barrel 300 norma improved and the Berger 245 gr LRHT. Id gotten the barrel broke in/done speeding up last weekend. I tested n570 and there was two nodes that were each over a half grain wide. 2760 fps and 2795-2800 fps. The lower node didn't shoot near as good as the upper node which is still a very mild load. I shot 3 shots of the upper node into 1.6"/.171 moa@890 yds and it had .82"/.088 moa vertical. When I did the ladder test this powder charge also impacted the same spot on the target as the charge right next to it. As a side note the 245 LRHT impacted at the same spot vertically at 900 yds from a velocity window of 2765-2810 fps. So the harmonic node is a mile wide as is the powder charge window. Seeing as this is a very mild load the brass will last 30+ firings. At 2800 fps this 245 berger has about the same amount of wind drift and energy at 1000 as a 215 gr berger with a muzzle velocity of 3200 fps. After 1000 the 245 pulls ahead. I cant hit 3200 fps with a 215 unless its in a 26" barrel and the top node of n570. Im using a mild load of n570 with this 245 lrht and a 22" barrel. For a comparison to a 6.5 prc and 156 berger the 245 gr has as much energy at 1000 as the 156 berger at around 350 yds

Recoil with the Silencero Hybrid 46 and a 30 cal anchor brake on the end makes it super easy to spot hits with. The brake on the end of the suppressor makes a huge difference in recoil reduction. Was noticeably less recoil than when the 338 ultra suppressor was on it. Itll be interesting to try out the TBAC SR magnus S RR when it gets here in a few weeks.
