I decided to load for my Win mag
I would load 210 or 215 bergers but as most know ...cant find em and might not stabalize them
bergers twist calculator says they are
I can buy 212 eldx but dont really want to same issue, they need a 10 twist
PLEASE
ANY experience with 300wm reloading success with 1 in 11 twist
and any with the Bergers
Thnxx in advance

What is your altitude, and the most common altitude at which you will be shooting. This can make a considerable difference in stability. What I can easily stabilize at my hunting altitude of 9000+ feet of elevation, others can seriously struggle (or outright fail) to stabilize at sea level.

If you have not already played around with this, Berger has a great resource available on their website that will allow you to do quite a bit of predictive analysis on bullets of your choosing. Link: https://bergerbullets.com/twist-rate-calculator/

One additional advantage to Berger's calculator is that because it is their resource, it is pre-loaded with all of their companies offerings. This should benefit you, as you asked about the Bergers in particular. You can also add your own data to calculate other non-Bergers, as well by entering specific data from the bullets that you'd like to try.

For the short answer in your twist, you should be able to stabilize the 180 gr (and below) projectiles quite well. Many in the shooting community feel that some Euro/Nordic rifle manufacturers have chosen poorly in putting 1-11 twists on their 30 cals. I generally love rifles from these manufacturers, but strongly agree that they need to update their twist rates to common heavy-for-caliber offerings.

Shoot what shoots well in your gun. You will certainly discover what works for you in your given circumstance. Then, when possible - re-barrel your rifle to exactly the length, chamber, and twist that you want!

Hope this helps.

Edit - I just re-read your original post, and see that you are already familiar with their twist rate calculator?
 
Drop down in bullet weight to something fully stable for proper terminal performance. Want your bullet to track straight and not tumble on impact. H1000 with the 215 Berger's is great in my 300 WM.
 
A 190g will be stable in a 11" twist, they are in a 12" twist.
I can't get ANY Berger bullets at all, not even on my lookout list anymore.
Try something else, the 212 might work depending on altitude, but there are dozens of bullets to choose from and Berger just aren't on the shelves.

Cheers.
 
I have some 190 VLD Hunting I will sell you. I think I have 3-350 of them if I remember correctly. PM me and maybe we can make a deal.
 
Just saw 175 and 185 Berger VLDH at Bruno's yesterday. I am loading the 175 Berger's and some 168 Sierras to try in my 300 Win Mag.
I just bought 200 175s and realizzed even though I have 20000 LRP I dont have any magnum large rifle
New quest me thinx lol
Now I need to find if the large will work or if I NEED the magnums

yup, tikka 1 in 11
I did see Walts bullets will stabalize in an 11 (210 and down)
Ive got 175 grain .334 and .335 bushings
LOTSA H1000 and reloader 23
20000 LRP but no magnum primers
ALMOST there lol

turns out the web site says the 210s will stabalize.
 
Temp is the 2nd most factor with altitude being 1st. Velocity coming in 3rd. 1st edition states 11 twist up to 210gr. Bullet length of the shorter heavier could be manageable with 11 twist? Go to JBM and try your inputs.
 
Has or does anyone load Win Mag with large rifle primer
or is it a must for LR magnum?
There has actually been a considerable amount of research/testing done on exactly this topic.

Many shooters have found great results in using standard (non-magnum) primers in 300 WM & others.

Magnum primers are certainly not essential for these loads, and you may actually have better results with std primers.
 
I have not had any problems with shooting 180 gr Partitions or Accubond bullets and can't remember any running away and having to chase them.All fell close to where the bullet impacted them.
My longest range was 610 yards,601 yards,500 yards,437 yards an many that I never ranged as I knew how far it was from each electric line stands and some 200 yards and some slightly over that.All died.
Even with that I know those that shoot farther may have a beef with 180 gr versus over 200 + gr bullets as they carry better at long range.
Just a thought.
