First, 35 Whelen rounds are impossible to find in these environs. Second, its one heck of a shooter and a killer. Our Shaw barreled Ruger 77 is as accurate as any rifle we own excepting the RPR. Brenda Lea’s CVA (for Primitive use in Louisiana) takes down critters like a sledge hammer. (Two deer harvested this year with this rifle). It is really versatile with rounds heavy enough to take down anything that walks in North America, it can also be downloaded with plinking rounds using .357 bullets And pretty much everything in between with BOOK Certified loads.
The Whelen was created during the early 1920’s when the only way to get a Big Bear rifle (.375 H&H) was to order a double square bridge Mauser action and having a custom rifle built. The action alone was outside the affordability of the average North American Hunter. With many affordable 1903 Springfield rifles for sale and .30-06 brass very readily available, somewhere between Col. Whelen and the gun makers Griffin and Howe, the round was developed. Controversy still exists as to who actually created the round. Not that it really matters.
With the advent of the affordable, long action Model 70 Winchester in the middle 1930’s, the big Whelen became somewhat irrelevant. Still it hung on. In the late 1980’s, Remington standardized the round and started chambering rifles for it. Unfortunately with a 1-16 twist. Now, many will report that with today’s bullets, this twist rate and the light bullets are all’s one needs for the Whelen. Still, bullets as heavy as 300 grains are available and a 1-14 twist is better for these bullets and a 1-12 twist will stabilize the light bullets and shoot the heavyweights just fine.
180 and 200 grain bullets designed for the .35 Remington are killers for smaller game such as Whitetail at reasonable distances. The heavier bullets such as the Nosler Accubonds work pretty good for heavy game. For my money, a bit too much for deer but I have taken two with the 225 Accubond. One went from stern to stem and really messed up too much meat (bad, BAD choice of shots on my part but I had not seen a decent deer in two years and the durn critter would not turn to give me the traditional shot. So, I tried to put one up the tailpipe and missed by an inch. Destroyed an entire side of that deer). 225 and 250 grain bullets work much better when the shots have to be stretched out a bit, but good, solid 180 grain and 200 grain mono bullets can provide good results, just the BC suffers with a wide short bullet.
Danged important. Be especially careful not to set the shoulder back. Not much of a shoulder to begin with and it is easy to set it back. Otherwise, as said it is a really versatile round. As mentioned, the improved round provides a more secure headspacing.
Now for a real block buster, while maintaining .30-06 action length and standard bolt face, check out the 400 Whelen. Elmer thought it was the round. Just make sure you get the improved round. Headspacing is a bitch.
