Yes, nothings free. A dear friend gave me every thing I need to shoot 223's for many years to come. But can you get 3800 fps with 27.0 grains of powder?
Sure, shooting a 40gr bullet in a 24" barrelled .223 Remington!! The Nosler 5th shows a max load of 28gr Benchmark with the 40gr BT or BST at 3860fps, whether your rifle can do that is another matter. They show other loads that do it too, 23.5gr N120 @3810, 25.5gr AA2015BR @3796, and 27gr N133 @3812.
Get yourself a
current manual or two, and work up the load, be sure to read first, shoot later!! Read the sticky in the Handloading forum, it has good advice for new handloaders.
