I had a Seekins element with a 20" barrel and was pretty disappointed. I have recently bought a HCR with a 16" barrel and love it. In my opinion it is the best option to carry expansion velocities to 800 yards with a 16" barrel. Compared to a 7PRC is shines with a short barrel. I sold the Seekins because with a 20" barrel there was no meaningful performance difference and the ammo availability and cost favored the other 7mm's. The factory 7BC guns seem to be regarded as finicky, not dissimilar to the 28 Nosler. There have also been some significant QC issues with Federal's ammo, to the point that two of the original program developers paused manufacturing rifles until Federal fixed the issues. Hope that helps.
