I bought a used '88 700 Classic in 35 Whelen back in '95. I had it reamed out to the 35 Whelen Ackley Improved. I took that rifle in '96 to South Africa for plains game, using the older Barnes 250X at 2600fps. I killed Blue Wildebeest, Red Hartebeest, Zebra, Kudu and Gemsbok with it. I only recovered two bullets ( lengthwise shots on the zebra and Kudu) I later foolishly rebarrelled/converted that rifle to a 416 Taylor and promptly sold it, too brutal in recoil, wow!) In '99 I found another pristine 700 Classic, also an '88 model and had it reamed out also to the Ackley Improved with the same reamer. This time I worked up the 200X ( the one with the secant ogive) to 2970fps! I took it back to South Africa in 2002, and shot another Zebra ( at 250yds) and a Black Wildebeest ( 347yds) no bullets recovered. I used the same rifle and the Woodleigh 310 soft nose going 2400fps on a Eurasian hog up on the Michigan UP a couple years ago. Big hole, no bloodshot meat! I have a load with the 250 Nosler partition and the Speer 250 going over 2700fps and the newer Barnes 200 TTSX going 2950fps...but no kills yet with either.
I have been impressed by the milder recoil, yet tremendous killing power of the Whelen ( a standard Whelen like yours loaded properly does everything my Improved does on game, no biggy) In fact, I no longer use any magnum cartridge, and I have used the 300's, 338's and 375 H&H! Up to 350yds, I could never tell any difference on elk size game and down between them and my Whelen! As far as I have been able to prove, by using it, it is indeed an "all around" cartridge! I use a Leupold 1.5x5 and a Bushnell 3200 2x7, both with Leupold QD rings. I like the 1.5x5 overall but the 2x7 has the Rainguard coating which I pair with my Brown Precision synthetic stock in early elk season ( rain/snow) I use a CDL wood stock in really cold weather, lots warmer to hold! ha R15 with the heavies and H322 with the 200s work best in my rifle. I only use a magnum primer with the Nosler 250 PT load, the rest get a CCI BR2, all in Remington cases. I love my 30-06 Mountain Rifle, have a strong sentimental attachment to an older Belgium BAR .270 and a soft spot for my gee-wiz custom Model 7 in 22-250 Ackley...but this 35 Whelen Ackley is the one that just "might" get put in my coffin with me, lol! Good luck to you!
