That should be doable in a 27" barrel, the 150smk with a moderate charge of H4350 in new Lapua brass at .015" jump averaged 2680fps from my 23" Bartlien barrel.A little update on this new bullet. This baby is long. I mean I guess that is to expected but OAL to touch the lands in 2.95". I will be jumping them .050" to keep them magazine friendly. This rifle has a little longer than average chamber and to touch the lands with a 140 ELD i am at 2.86". I decided to do initial load development with imr4831. I have lots of it and it is slower burning than H4350. I hope that means less pressure overall. If I get 2800 fps from my 27 inch barrel without pressure I will be happy. I will update this thread with my results.
Man that’s screaming fast. Wow! These peaked my interest for sure!I was able to get some load testing done today. I loaded 17 rounds up. I am using IMR4831. Starting at 42 and ended a ways above max at 46.5 grains. I am doing 2 things. Checking where the pressure ceiling is in my rifle and looking for flat spots in velocity. My results are as follows.
42.0 2710 fps
I have a 15 fps spread from 44.1-44.7 and I think I will look into this a bit more. This barrel is a bit faster than others I have had but I did not expect this much speed.
Book max is 44.3 gr according to the hodgon load manual. I did not see pressure till 45.9gr and have no intention of loading that high.

That shouldn't be too hard, with rl16 and norma brass I got a great node at 43.3 grn and a great group sd of 5.4 moving at 2834 with the 144 gr bergers. mine was out of a 26 inch barrel. If i was you I would try some loads between 43.0-44 grn.Just ordered a few hundred straight from Barnes. Hopefully I have them before the weekend to see how they do in my creedmoor. I would like to see 2800fps with RL16 and a 24” barrel.
