North...what is the LOA of the bullet seated to the canelure in the .350 RM?...do you have to seat deep to keep the LOA under 2.800?

Thanks...Bob

Bob, right hand cutaway cartridge below is the 350RemMag at 2.820" with a 300gr Barnes Original seated. There are no canelures on the Barnes Os I have. That bullet is out of print now. I have a small number of them but never actually loaded and fired one myself in the 350RM. But Con has elsewhere in this thread (bottom page two) reported using 310s with satisfaction from his Ruger77 in 350RM - 12" twist I believe. The 300 Barnes Os and the 310 Woodleighs are the same length.

L to R
35 Whelen - 310Woodleigh 3.280"
350WSM - 310Woodleigh 2.865"
358Win - 310Woodleigh 2.865"
350 Rem Mag - 300 Barnes Original 2.820"

Quite a few years ago I bought 2 boxes of the 300gr Barnes Originals from an outfit that was going out of business. They shot very well in my Rem 7400 (1 in 16" twist)at around 2340 fps.

Also, in my Rem 673 in 350 RM. It too had a 1 in 16" twist. Atkinson is right, H414 is an excellent powder for that bullet, as is RL-15. They are no longer produced by Barnes but I expect the 310 Woodleigh, being the same length, would be similar in performance.

Guys you lovers of 35 cal may want to check out www.hawkbullets.com as they make 275gr and 300gr bullets....

Awesome stuff guys!!

I’d be looking at stability programs before I’d try, even before I’d buy a box of bullets. There’s several programs on the internet.

Elevation and temperature, humidity are some variables that could effect stability. Just because one guy says it works well for him doesn’t mean it would for everyone in different environments.

I’ve been shooting 35 caliber bullets since the 60’s but have not shot anything over 250 grain - maybe 275 grain once, but I do not recall accuracy and had no chronograph then.

My biggest 35’s are a Whelen and a couple 350 RM’s. A 358 Norma likely would push a bullet faster.

Any more information here like links to some data?

NOE and Accurate offer 310 cast bullet molds. I have a Accurate. I have 358 Win, 35Whelen and 358 NM firearms.
Twist calculators say 1:16 works fine for the 300g. All mine are 1:14. But that always comes up.

Little is found across the webs and RL15 is the Whelen powder and us about all that is found. (I have 1/4# and no prospects for any more anytime soon)

Try adi 2209/H4350 with the 310gn Woodleigh RNSP
I use an 600mm or 2 ft drop tube to load 63gn of the above powder and get 2,455fps at what appears safe pressure in my rifle with a 25 inch barrel 1 in 12 twist.
62 gn of the s a me powder gives me 2,340 fps
These loads are safe in my rifle only.

If you don't use the drop tube you will get 60gn of 2209/H4350 and very compressed. The drop tube allows more powder and minimal powder compression

Whelen B
I was using the Woodleigh 225gn PPSP in my standard Whelen with a 1 in 12 twist, 25 inches long. The load I used was using Hogdon CFE223 and chronoed velocity was 2,900 fps. This is 200fps over the Woodleigh recommendation. I used it in Namibia to shoot my big burchells zebra stallion. Impact velocity was still around 2,700fps and bullet performance was faultless. It broke the near shoulder destroyed the internals and then broke the offside shoulder. The bullet was found under the skin on the off side and retained 74% of it weight.
If I could upload a photo I would.

Talking to the owner of Woodleigh Geoff McDonald about velocity he said you can push them a bit and they should still work well.
The following are the velocities I get in my standard Whelen using Speer loading data and Sierra data as well as load from a disc
225gn 2,900fps
250gn 2,700fps
275gn 2,60p fps
The above loads are using Hogdon CFE223

The 310gn Woodleigh RNSP is at 2,455 fps with no pressure signs but my working load is 2,340fps. This is using adi 2209/H4350. I plan on using this projectile on a scrub bull hunt next year

All loads were chronoed with a chrony chronograph 4 meters from the muzzle. Rifle is a Stevens 200 rebarreled with a magnum profile 25 inch stainless steel barrel with a 1 in 12 twist. The rifle is stupidly accurate.
When I was in Namibia 3 hunters and 2 PH were given 2 projectiles each. 2x225gn accubonds, 2x 225gn Woodleigh PPSP, 2x250gn hornaday round nose, 2x250gn Hornady spire point Interlock and 2x 250gn speer hot core. The resulting 10 shot group at 100 yards was 1.2 inches nicely centred 3 inches high . My PH wanted to keep my rifle but that wasn't going to happen.
I have had great fun working up loads for the Whelen over the last 4 years and have got to know what it is really capable of when loaded to its full potential SAFELY, NOT HOT RODDED but using reliable load data from speer,Sierra, nosler and load from a disc.

Wow, old thread, good stuff though, my 14 twist JES rebore 35 Whelen will spin the chit out of the 310gr Woodleighs, i cant think of a beter big bear, timber elk or moose load, cape buffalo in Africa where legal would happily be added as well.

I had one of the very first 700 Classics in 35Whln and damned if I could find a load that stabilized the common 250 grain bullets. At 200 yards they flew like bottle rockets.

LOL. There's a reason this thread was dormant for 11 years--time for a new chambering!

Sure thing…..😂

Anymore info on the 35-06 is appreciated. 👍
