Good afternoon, my wife recently came home with a used omen 300wm because it was a gun I wanted at one point. I live in a non AR friendly state so they aren’t seen very often let alone come up for sale. I’ve been searching around and have come up on a lot of omens for sale, and Nemo made you tube videos but not much of info from the shooters.
this is an older version with a 22” 1:8” twist barrel and non adjustable gas block. I spoke with Nemo about upgrading the gas system and it’s about 800 bucks. I plain on loading my own 215h hybrids with h1000 because that’s what I have on hand for my bolt gun.
I’m just looking for general feedback and load data from anyone who has any first hand experience with the older Omens 2014-2016

You may want try a faster powder for a gas gun. Sometimes the slower powders are too slow for the gas system, resulting in incomplete burning of the charge, as well as, other signs of over-pressure that you may not see in a bolt gun.

thanks , I’ll start looking into it. I emailed Nemo about it today and they gave me the legally safe answer. What burn rates do should I be looking at h4831sc? With it being a 1:8 I’d like to run 215/230s

I've got the Falkor 300winmag and it has an adjustable gas key on the bolt. You can get the adjustable gas key from Rubber City Armory. I started at 75 grains h1000 with the 215 bergers and worked up from there. I was over 2800fps with my 22inch barrel. I have since switched to RL26 for more velocity. Currently have a 20 inch proof carbon 1:10 on it. Make sure you use good fundamentals, hold firm into shoulder and get straight behind inline with rifle, to follow through/absorb recoil.

I don’t know why the photo didn’t attach. Years ago I had an opportunity to buy the first Oman, I was torn between a bolt gun and the omen, obviously I went with the savage first, put 1500 or so rounds though it the first year I had it, I tell everyone it’s just a savage but it shoots very good. I have a 338Lap two 260rems and a custom 6.5SS in the work. Having the Nemo now rounds out the long range collect.
I’ve been searching for a few days and I’ve found some good starting info. Once I get the mount for the mark5 and some fresh brass I’ll start with the load work

Thanks for the info, I shoot my 13 lb 300wm bolt gun with out a brake. I put one round thought the gas gun to get some fired case measurements... it’s barks a lot louder then it kicks
