Having fun indeed!- I'll check that thread out.
I'm going to do a 35 WSM another time, that really sounds like a good round.
At this point, I feel like I've concluded I want to get into the 35 Whelen AI through RKS in Wimborne. I just need to find a good gun to bore out.
I think for a pad I'll be going with a FalconStrike or the AirTech from Pachmayr. Depending on geometry, I'll have a drop plate on the butt to get me more upright on the gun... it looks goofy, but I'll never go back!
Air Tech is a Limbsaver pad. Effective enough, a bit spongy, but would do the job. Pachmayr grind to fit is imo a much nicer, classic look, that performs every bit as well or better without the gaudy factor.
I'll never begrudge a shooter for building what he wants but for the marginal performance difference achieved in AI'ing the Whelen (roughly 2%) it wouldn't be a preferred option in a custom rifle for me.
Re the Whelen chambering itself I really, Really like it. 225 ABs at 2750 that I could squeeze an extra 100 out of are its sweet spot, along with the occasional 200gr ttsx at just under 2900 perform very well also and keep the mono speed up.
Mine is a semi custom Rem 700 action, 22" barrel, in a Wildcat that both Gary Flach and Nobby Uno had a hand in and all I can say is if I had to dump any of my mid bores it'd be the last to go. Consistent 5/8" groups with the ABs and many cloverleafs which with my marginal shooting talents says a lot. It is far beyond the expectations I had when it was a pipe dream.
Any way you slice it the 35 Whelen is a very capable 400+ yard chambering that runs close to the 338wm speed and energy wise using same bullet type and weight to 275 - 300 yards. After that the 338 ballistics take over. If ballistics ever became a prime concern I'd just carry one of my .284s.
Been hunting and shooting a long, LONG time in AB and Sk and if I had to count the number of times I've taken hunting shots beyond 300 yards on one hand I'd have fingers left over. Performance wise I've never seen the need to add in the 10 - 12 lbs of recoil the magnum adds and can't say I've ever felt undergunned when hunting elk and moose in heavy g bear country along the Simonette. Chances are it doesn't make much difference what cartridge you're carrying should an ugly situation arise and more important factors like, what can I shoot competently while crapping my pants kick in.
For what its worth my 35W weighs in at 8lbs scoped and its a pussycat on the recoil side loaded at average. Next to zero difference between it and a 7rm/06. If you'll reload don't be afraid of using newer powders than many manual recommends and use at minimum Speer #14 and newer as reference. Much of the Whelens load data was assembled during the Paleolithic era and didn't include newer at the time powders like IMR 8208 XBR, Alliant Pro Varmint, CFE 223 and Alliant 2000-MR. It wasn't legitimized by Remington at Saami until 1988 after living as a wildcat dor 66 years, and prior to that date guys were already reloading 250 gr to 2550 - 2600 fps without knowing true pressures until 52,000 CUP became 62,000 PSI. That made 250gr bullets loaded to 2700 possible in 24" barrels. 225gr is optimum "everything" tho imo. Bullets, powder, and obviously brass are easy enough to find. Factory loads not so much depending on where you do your shopping. I had Prophet River special order several boxes of factory Nosler Trophy 225Abs for me back then and I had what I needed for brass to last a while.
Enjoy whichever .358 you choose.
