I have a Remington model 700 PSS in .300 Win mag that I have been slowly upgrading over time. I have dropped it into an AICS Chasis stock, installed an over sized bolt knob, and installed a Badger Ordnance extractor.
I am now going to have the rifle sent to my gunsmith to have the following modifications:
- Install a match grade Bartlein barrel.
- Install a Badger Ordnance Thruster muzzle break.
- Bead blast and coat with flat black Cerakote.
- Tune the Remington trigger (The gunsmith talked me out of installing a Jewel trigger).
My question is regarding the barrel twist rate. I handload Sierra HPBT's from 180gr to 220 gr, and need to know what barrel twist is best for these weights?
The barrel that Remington manufactured the rifle with does a great job in my experiences, but I'm sure I can do better.

remington factory barrels are 12 twist for 30 cal, and i don't think in a 300 win mag a 10 twist is realley necessary. having said that, you tend toward the higher end of bullet weights, and since the cost is the same, i'd reccomend a 10 twist.
good luck!

How far are you going to push that 300 Win Magic(Yardage) and what grain bullet are you gonna use in her?

Actually, the factory spec on the twist rate is 1:10". I'm sure that a better twist rate exists...

I have been sticking with the 220 gr Sierra HPBT, but I may go down in weight depending on what I am looking to do (hunting deer, wild hog, ect).

In my 300 Magnum rifles, I always tend to go for the heavier bullets. If you are going to hunt big game, the 220g Sierra HPBT or the Game King are an excellent choice. If what to tune this rifle for 1,000 meter paper punching, I would learn towards the 168 g Sierra Match king
I believe the Remington spec is 1 in 10 twist.

Opinions are many but in my 2 cents worth.I do load 168 grain Matchkings but I relegate them to 600 yard fire from my 300.
I do like the 190 grain MK for over 600 yards..
I experimented a bit with the 175 grain Matchking and though it is good bullet for long range performance,I prefer the 190 grain.The 220 MK is also a valid choice and most suitable for 1000 yard shooting...as well as the 220 grain Spitzer for whacking big critters.
Ballistic coefficients and terminal performance aside..If I wanted to hunt whitetails and hogs with my 300, which I do.I use a 165 grain Hornady SST and have used 150 grain ballistic tips..The 165 grain Hornady bullet smacks the living crap out of hogs as well as whitetails....when it comes from a 26 inch tube.

It has been my observation in the realm of 30 calibers the the 1:10 twisted rifles are best suited to the 165-168 grain class of bullets to stabalize fot best accuracy as the 150s on the bottom of the heap and maybe the 180s on the top but if I were gonna be shootin lots of those 220s I think I would take a serious look at a 1:9 twist barrel,and thats just my 2 cents on the matter...................

It has been stated that a 1 in 12" twist will not stabilize 220 gr. bullets. Who stated that nonsence so very many years ago is way beyond me. I doubt if anyone knows for sure. A very long time ago, I quit believing some of the crap that some of the gun writer spewed from their typewriters (remember them?) as what they said did not go along with my experences. So, when a friend who built custom rifles offered to rebarrel an FN Commercial sporter that I had that had a bad barrel (I got it cheap to use as a donor.) offered to rebarrel the gun for me at cost, I jumped on it. As I shoot a lot of cast bullets, I went with the 1 in12" twist as that's a better rate for lead bullets. I kept hearing that BS about the 1 in12" being no good for heavy bullets so I loaded up some and found out otherwise. An article by Jack O'Connor saying that it was all BS as well made me wanting to find out the truth of the matter. Jack was right and the "egg-spurts" in the gun rags were wrong. I even went to the trouble to take on one of those "egg-spurts after he wrote (parroted) than old line of BS in one of his articles. I even sent him targets, and told him that if he was anywhere near my neck of the woods, he could watch me load the ammo, and the watch me shoot some and he could shoot some and learn the truth. He declined. No guts no glory sez I.
