I would go with the 1:8 barrel 28" you will have no regrets it will handle the light as well as the heavy bullets, and the extra velocity is nice when you go long range. A good brake and you will be able to shoot all day without a sore shoulder. Keep in mind that the added rifle weight will help with the recoil. I have a tikka t3 with a pac nor ss custom barrel and 28" with 1: 8 and 11 lbs with scope. it is almost 3 shots in the same hole at 100 yds. As technology evolves so will better bullets and heavier wts, and 1:8 or faster will be the norm of the day. Twenty years ago 225 gr. were rare or unheard of.
I'm shooting on a Remington 700 platform in .300 win mag. I built it with a 5R 1:10 twist and a magpul LA stock with a detachable mag. I also went with an M-16/Sako extractor and a .250 recoil lug. I've worked up a 165gn Hornady sst. At 500yrds and a fair wind I can cut .750" groups. It's a bit heavy at 11#'s but not all that hard to carry. It's also set up with a 3.5# timney trigger and a brake. Felt recoil is super light, so my follow thru is much better without the muzzle jump. Last Saturday I took a head shot on a Doe at 375ish yards in a cut corn field. The bean field right next to it hasn't been cut yet so it was out of bounds. I just figured on a solid hit or a clean miss cause I didn't want to drag her out of the beans. I hit her right where I was looking just below and behind the ear. I picked out the hair I wanted and sent it. She dropped like a rock! Super cool except for dragging her out. Anyway, this rig took me 3yrs to put together, I'm disabled and moneys tight. But it's been an awesome build for me. Maybe it'll give you some ideas towards what you're looking for. I didn't know it unti after I started, but it's close to the Remington 700 Sendero. Good Hunting
Why wast time and money on a custom build when you can get a Christensen arms rife line fo 1600. I have one and it will shoot .5 mos all the way out to 1000yd . I shoot the ELD-X in 178 gr. at 2978. Most rifles will shoot better than the shooter. I live in the west and hunt deer to Elk with it any where from 200yd to 1000yd. There is no need for any bigger than 180 to hunt or steal with. Optics will make the difference.

Building rifles is always a fun time, and they seem to hold value a little better than an off the shelf gun, given, they cost more initially too though.
I built and shoot a .308 Norma Magnum (very similar to .300WM) and I went with a 28" Bartlein 1-9 5R Sendero contour. I shoot the 208gr ELD-M with excellent accuracy. I chose the 9 twist over a 10 so I could shoot just about any 200+ grain bullet available. People say too fast twist won't shoot as well, but if you stay to heavy for caliber bullets you won't have a problem. Now with 150-180gr bullets the 1-9 is probably too much, but I believe it's smart to go with if you are building a magnum and intend to use heavy, high BC bullets.
I always say I would rather be a little over stabilized than be under stabilized and have to jump down to a ballistically inferior bullet. You can go too extreme with too fast of a twist and you'll potentially blow up bullets or distort them. A 9 twist in a .300 with heavy bullets is perfectly fine.

If you have the reamer with the correct freebore it's best to do it in one shot. Less chance of anything going wrong that is why people send dummy rounds to reamer makers like JGS or Mansons.
Yes throaters done properly are the next best option.
I agree with L.Sherm. Why do something in two steps when you can do it in one with the same results. There's nothing wrong with throating a chamber longer if you already have a reamer on hand. If you're going to order a reamer though from the ground up, make a few dummy rounds with the bullets you intend to shoot at the O.A.L. you want them at and send them to the reamer maker.

The smiths listed above don't make those mistakes.
The concept of too fast a twist is a myth.
I'm not sure why you quoted my comment, and said the smiths above don't make that mistake. I'm confused
It was - but spinning it too fast makes it stay angled nose up as it descends creating an awful angle of attack /yawl that is not aerodynamic so starts to tumble. What you want is a "gracefully thrown football" remember how the perfect spiral noses down as it heads into the receivers arms. But bullets are not football shaped - yet. And yes it is the newer science in extr long range shooting
Oh. To my limited understanding, that is true - until it begins to go transonic to subsonic

OK, ya really got me wondering, what is the diff. between the sami reamer and the A191?? Thanks in advance.I would steer clear of SAAMI reamers and order a 'A191' reamer.
You will thank me later, trust me.
As to barrel length and twist, I prefer 26"-28" with a 1-10" twist. I shoot 230's in 28/30/32" 1:10" twist barrels every other week with ZERO issues regarding twist rate.
Sure, a 1:9" twist will give some margin for error, but a 1:10" twist IS actually fast already in 30 cal.
Cheers.
