Today- 18" barrel 37gr CFE223, not max pressure. 110gr HPBT=2855fps chrono did not read above 37gr. 40gr was not max pressure. 37gr CFE223, not max pressure. 120gr SST=2736 39gr CFE223, Max pressure 120gr SST=2860 primer starting to flatten, no cratering. 38gr CFE223, 130gr Berger=2692fps-no signs of pressure.
Just a swag here, the 110s should hit 3000 or close, 120s as shown 2850-2900 and the 130s 2750-2800 out of a 20". 85gr TSX 3300???

38gr CFE223, 130gr Berger=2692fps-no signs of pressure. That's a pretty serious long range load right there.

36gr 8208 130 Berger=2788fps Holy Flippin Moley! -Primers show light cratering here. I had 1 shot at 2855. Either load is 260 Remington with a 24" barrel territory!

H335 turned out to be a little slow with the 85gr TSX 40gr =3139 with no signs of pressure-max case fill. RE7 on the other hand worked out great-36gr RE7=3291 with no signs of pressure, could probably go to 37gr which is pretty close to max case fill. RE7 For the light ones, 8208 and N530 for the 130s. 10x, H335 and x-term may work for the 100s. While all powders may not produce the most velocity, everything from RE7 on the fast end to Varget and RE15 could be used with some bullets.

For those that asked about Varget. 35gr +2560fps. It wasn't near max pressure so it maybe possible to get 36gr in the case bumping the vel another 50-60ps. 2600 max IMO. RE15 will likely be the same. N530-35gr=2801fps max pressure not max fill.
