Been kicking around putting together a carbine-size 35 caliber since earlier this September after this year’s season.
I had to hunt some new areas due to fires around me and I found my current setups to be unsuited for these new places.
Specifically, I spent my season in some very heavy timber and the river bottom foothills rather than my typical high alpine where stops can be far and fairly open.
My go to rifle the past several seasons has been a little 7mm wildcat set up for chasing bear/bucks in these areas around me. It has a 4-20x Tract which was actually a step down from the 6-24 it wore last season.
4x is still too much for the areas I found myself locating critters this season so I opted for my little ultralight 6 ARC which wears a 2-10x36 Credo HX. Excellent scope! Sadly, I just didn't have the confidence to send a round on a monster bear at 150 yards which left me wanting more. A lot more! Like .338+
I considered creating a wildcat or rechambering my ARC for one of the AR rounds that are fairly new to the industry before my practical took control and pushed me towards the 338 RCM. I thought I successfully had one purchased only to have the sale fall through which sent me back to the drawing board.
This deal fall through the day before Lipseys announced their limited run of the Alaska Bish Rifle in 35 Whelen and 9.3x62 and try as I might, I could not find one anywhere but gunbroker with a massive price bump attached. I also looked into ordering myself the new 16” 358 Hawkeye Hunter. It would seem this has also been a very popular choice because neither of my dealers could obtain one and put me on a wait list.
After trying my best to find/buy a damn Ruger through a few dealers constantly failing I started cruising GB this past week…
I picked up a stainless Montana Rifles 300WSM and will finally have myself a 35 caliber carbine!
I’m currently debating sending to JES as soon as I pick it up this week to get bored out and rechambered to 35-300 WSM or just buying a new Douglas #4 and having my gunsmith install and true and tune the barreled action up for me while it’s there.
I also ordered a Bansner Miller stock to drop this barreled action into once it’s all finished up. I’m hoping for a rifle in the 7.5-8.5lbs range scoped and loaded and figure this will be an excellent everything rifle going forward.
The ARC, 7mm Moses and 30 Nosler may get jealous as I imagine they might be left sitting a lot going forward with this new 35 and my custom 30-30AI getting most of the attention.

Already bought the 300 WSM.
It’s gonna be a rebore regardless and realistically require necking up 300 WSM brass to load as well.
There are several advantages the 35 has over 8mm, not the least of which being the ability to plink with very inexpensive handgun bullets loaded with Trailboss for smiles all day.
 
I built a Sambar and used it for several years while guiding and hunting... it was a pleasant and effective cartridge. After I built a .358-375 Ruger, I let the Sambar go to an admiring friend. Subsequently, I built a .375 WSM and have used this cartridge on moose, black bear and eight species of African game. Personally, if I was starting from scratch and looking to build a cartridge on the .300 WSM case, I would go with the .375 over the .358. The .375 version has more applications and does everything the .358 version does, only slightly better. As far as plinking goes, MEH... rimfire and .223 and PCC's are better in every way, rather than running pistol bullets down a medium bore bolt action rifle.

HAD OUR R-93 300WSM BARREL BORED TO 35 SANBAR (358WSM). SADLY HAVE MORE GUNS THAN TIME TO SHOOT EM ALL AND WE HAVE NOT EVEN TRIED IT OUT YET TO REPORT.

I’ve kicked around doing a 375 variant off the WSM case and I guess nothing is final until I send the rifle off for rebore or buy myself a new barrel
My friend, Rich Sherman, designed the 375 Yukon before selling his company and I continue to be tempted by this powerful little thumper.
There’s a gentleman who built a rifle on the 375 Yukon and slings 300gr Chinchaga bullets at 2720’ from his 20” barrel!
The 375 is definitely tempting!

To the best of my knowledge the 35-300WSM was the brainchild of an Australian called Briel Jackson who called it the 35 Sambar.
It appears to be a good cartridge but isn't doing much the 35 Whelen isn't already doing.
To me any 35 is a good choice.
Have fun with your new toy.
JES will do a great job but get a 1:12 twist.

I have to say I'm very impressed! The trigger is wonderful, the action feels great and everything is better than I expected.
The barrel is heavier than I thought it would be based on photos so it will be going down to JES for a rebore.
Very happy with this purchase
Just ordered myself some 35-300 Redding dies
Considering rings and bases for this rifle and think I've landed on Talley's steel bases and steel non-detachable vertical split ring. Eventually I may swap to the detachable option and add iron sight but for now, I'm going leave it alone.
Anybody use this combo on their heavy hitters? I've seen the combo used successfully on a 378 Wby and figure it's plenty good enough for my little 35-300 WSM.

Great choice going with JES. He did a great job on my 35 Whelen rebore and it's very accurate. You will need to be patient as he is very old school and doesn't even answer the phone, lol, but it will get done and back to you for a great price. I would highly suggest getting a bunch of those pistol bullets, load them light and run a hundred or so through the barrel after you get it back, makes all the difference after a re-bore (luckily with the .35's you have this option to do it for cheap)

I’ve got thousands of 147gr XTP bullets and about 16lbs of Trailboss… gonna be a fun winter

Nice to have that trailboss! Can't find it anymore and it's good to have for oddball stuff like this. Used to load 5744 in .375 for light whitetail loads as well. Worked great.

@Wilkup
You only have one issue.
DO NOT USE CASES USED FOR SQIB LOADS FOR FULL POWER LOADS USE CASES NEAR THE END OF THEIR LIFE. or load up twenty and use them exclusively for your SQIB loads.
Bob
 
What is the reasoning behind this? I’ve never had a warning shared like this before.
@Wilkup
Apparently it has something to do with the case not sealing properly with those light loads and alters the brass in some way. WSM brass is thicker and harder to work than some other brass.
Our local gun writer and guru Nick Harvey always exposoused that this shouldn't be done because of the possibility of brass failure of brass used for squib loads if then used for full power loads.
If that's his advice with well over 60 years if experience before he died I will follow his advice and not tempt fate.

Guess I’ll be buying some cheap Winchester cases for Trailboss loads and save the Lapua stuff for the working loads.

Personally I'm not going to risk life, limbs or rifle to prove him wrong.
Brass is cheap the rest can cost big time.

I just traded for a 358WSM from a friend of mine. We went to S.Africa in 2024 and that's rifle he used. It is a real "Thumper".
1999 Montana receiver, Lilja 26"Barrel,Magnaported,Pendleton Composite Stock.
It's a real sweet rifle - would be a great choice.

Load that girl up with some nice 225gn TTSX and go have fun
Or if you can get them depending on game and distances a nice Woodleigh 225 or 250 RNSP.
Both those put a lot of big hurt on big critters.
Problem is it ain't doing much more than a good Whelen.

I started with Winchester 325WSM brass for my 416WSM. Expanding up to 416 noticeably thinned the necks. So much so that the resized neck only bearly grips the projectile, they must be crimped. The Bertram Brass with the 416WSM stamp on them have much thicker necks and resize perfectly.
Going from 325 to 358 is only 0.023" so you should be OK, but a lee factory crimper might be worth the investment.

Jerome, do you think my last post in rough camping must maybe shift as an article?

Good afternoon,

I'm trying to get in contact with Mr Butch Searcy. I have the opportunity to buy one of his rifles chambered in 577 nitro Express however the seller does not have any of the paperwork with the information about what ammunition or bullet weight was used to regulate it. I know he is not making firearms anymore but I wanted to reach out after seeing one of your post about him.

Hi - the only (best) method of sending you the .375/06IMP data is with photographing my book notes. My camera died so the only way I can do it is with my phone. To do that, I would need your e-mail address, as this
new Android phone is too complicated to upload to my desk computer, which would be easier and to down-grade, reduce the file sizes.
Best wishes
Daryl
