That is a nice lookin' shootin' iron.
The SIL had a bipod and put it on the grandsons rifle during assembly.
I purchased a Hogue full bed block stock for his to use on his.
They are nice firearms.
They do have some nice rifles, but with the offerings today, you can build something for a little less money.I use to visit the Sniper Hide Forum years ago and they offered a start up long distance rifle build based on the Howa or Remington action with a choice of short action calibers, barrel length, stocks, scopes, bipod, scope rail, etc. Always thought those were neat.
I actually read an article on another forum about SWAT cutting barrels down on a .308 an inch at a time and checked for a loss in velocity. It was not noticed until they got down to 18" and then it was only 33 fps. So, keeping the rifle. Gifting it to my son and I will be getting another in 6.5. Our future plan, when things change, is to take a beginners long range shooting class in Montana.USAF Ret: despite all the naysayers, the 308 Win has more than proven itself over the years. It held records at almost all ranges for many years. It is very easy to load for and get astounding accuracy.
Just for your info, I bought the Howa barrelled action from Brownells with the 24" heavy barrel. It was for my grandson to put together a rifle capable of shooting competition as a beginner. It is very accurate wven with cheap FMJ ammo.
I recorded his first shot, and he barely moves. He is 16 and at 6ft tall weighs maybe 180 lbs. Recoil is right at comfortable with no brake, so your rifle must be a dream recoil wise.
The only thing I can add is that you should have purchased the 24" barrel versus the 20", but no worries because your's will still shoot gnat's asses at 100 and beyond.
For grins, someone said that a 150 will not stabilize at long range.
Do some study on Palma Match and see what they shoot.
I have a Savage 6.5 Creedmoor. It is a hunting rifle. Yes, this is a .308. With the muzzle brake it is not bad.
