Anyone have a recommendation for rebooting a rifle from .270 win to 35 Whelen??

If so have you actually used them and pleased with the accuracy. Was it cut rifling or button rifled?

Any opinions on which type of rifling is better for this caliber. Twist rates?

Call Jesse at JES Reboring.

I bought a rifle they did and had been rebored to a 338-06 from a 30-06. It's performed flawlessly and accuracy is very good.

I think they cut-rifle everything after they rebore. Not for sure though.

Just remembered this...Arjun posted just last week his 35 Whelen that JES did.

I used JES to rebore a 30-06 with a tired bore to 375 Whelen. He did a great job. and turn around was ten days from my door back to my door. Never heard anything but good about JES.

Ten days door to door, that is remarkable service. Hell I do not even need a rebore but maybe I will make one up!

Another vote for JES. Had them rebore a Rem. 7600 to 35 Whelen. 3 grove, 1:10 twist. Shoots 275 gr Woodleighs into a skinny inch. Less than 2 weeks and it was back at the house. My "new" Idaho timber rifle! Andy3

I talked to him yesterday and I am going to send my 1885 to him ASAP. He said about a week will be all the time he needs.

Just had a 35 whelen rebore done by Jes, good shooter. To be tested very shortly in Zim!

I plan to use Jesse to rebore my Lee Metford to .375 NE 2 1/2 Flanged this summer, so I can have my "Von Gruff" Lee Speed ready for fall.

I have used High Plains Reboring a half a dozen times. Norman Johnson, 701-448-9188...they all shot an inch or better and the cost is half the cost of a new barrel..Leave a message, he will email or call you back..

Another recommendation for JES reboring. Very good service and 10 days door to door.

One poster has suggested a 1/10 twist on your 35 Whelen. I am very happy with my 1/12 twist on my Whelen and it shoots 310s very accurately, with no trouble at 200 yards. If you like the heavier bullets in your Whelen, I'd personnaly go with one of these two twists. Others may disagree.

As I have posted before, I am thinking about having a Ruger Hawkeye SS in 338WM rebored to a 358NM.

I have never done a rebore, so please excuse my ignorance and inexperience for this question:

For those who have used JES before (or anyone I suppose), is part of the reboring process, besides reboring the barrel, also rechambering to fit the longer cartridge (358vs338), and restamping the barrel to the new cartridge?

And does anyone yet know for sure the answer to the OP's question of cut rifling or button from JES?

Thanks for all your expertise.

Amazingly the 1885 is already back from JES. I have Ammo and will take to the range very soon. I'm really looking forward to shooting this rebore. Maybe next a 300 Ultramag to 404????

surefire7, Yes, rechambering was included with the re-bore, along with restamping the barrel. Pretty plain job on the stamping, but good enough for a Rem 7600. Can't answer your question on whether it was cut or button rifled...but a phone call to JES would take care of that. Andy #3

Andy#3,

Thank you for the information!

JES uses cut rifling. I have a 35 Whelen Ackely Improved he did that shoots fairly well. But nothing beats a full custom barrel for accuracy.

Thanks Truck Driver for the answer on the rifling question!

Received the rifle back from JES about 12 days post to post. Went to the range with Federal fusion 200 grain bullets ( factory Ammo) and had three primers fall out. Damn, now what?

Had the bore slugged, head space checked and chamber cast made and measured. To my relief everything was in spec. Took it back to the range, this time with different Barnes fctory ammo and some hand loads. Eureka, no problems at all and the primers all looked normal.

Conclusion was bad lot of ammo. Pulled the rest of the bullets from the factory stuff for reloading.

Had JES rifle the 1885 in 5 groove 1 in 12 twist. It shoots into less than 1" with the Barnes 180 TSX and my 200 grain reloads.

Sent a rifle off yesterday to JES to have rebored to 35 Whelen. 1/14 twist.

Hope to get it back in a couple of weeks.

Thinking about trying Remington ammo loaded with 200 gr Core Lokts, Double Tap ammo loaded with 225 gr A Frames, Federal ammo loaded with 225 gr TBBC's and Nosler ammo loaded with 250 gr Partitions.

Any suggestions? Comments?

Maxie, just sent an old JC Higgins (FN action) in .30-06 off to JES to have it rebored to .338-06. The bore had some pitting and as a result it suffered in the accuracy department . . . would shoot several shots close together then a flyer, several more together, then another flyer. I look forward to seeing how it works out.

I love the .338/06. Great bullet selection and enough powder capacity for good performance. I bored for the .35 Whelen for the LA. primitive we dalton season. When it comes back lets get them both to the range.

That should have read " primitive weapon season".

I'll bet that old FN turns into a shooter with the JES treatment

A friend of mine had a Marlin 336 in 30-30 rebored/rechambered by JES to 38-55.

The gun shot great. It was the 3 groove rifling.

I only got to see down the bore after/during shooting before cleaning. I did not like how the bore looked. The lands were swirly and the grooves were very shallow.

Now let me be clear, the gun shot great. The guy was shooting cast lead bullets and was moving them pretty good. I don't know if they were gas checked or not. But like I said it was not a pretty bore. I wish I could see it clean. He has since sold the gun. That is nothing to be concerned with as that is his hobby; buy/use/modify/use/trade/repeat.

. . . if your bore is pitted and accuracy is off to start with . . . what do you have to lose?

I have heard enough positive stories about the work JES does, both here and on the Marlin owner's forum, that I am willing to take the chance.

Maxie, please arrange for cooler weather for the range trip.

Mike, as I am leaving tomorrow for the AK moose and griz hunt, I'll try to bring some cool weather back with me.

Maxie

Stay alert, it happens quickly.

Mike,
What loads are you planning to use? BTW, great choice in the 338-06.

Thinking about 200 grain Nosler Accubonds on top of something like 53-55 grains of RL15. I asked JES to do a 1-in-10" twist on the rebore so I think (hope) I should be fine with either light or heavy bullets.

You should be just fine with the 1:10. That load combo you're planning should work well. I'm using RL-15 and 210 gr Scirocco II in mine.

I'm a fan of the RL-15 as it also works great in my 375 H&H and 22-250.

Put me in the RL15 fan club as well . . . I wish there was not as much lot-to-lot variation in the powder but otherwise it is great. I probably shoot more RL15 than any other powder . . . I particularly like it in big bore rifles since it reduces felt recoil over powders like H4831 and the like.

Mike, Dustin recommended a 5 groove rebore to keep the bullet more concentric. JES does a lot of 3 groove. I'm no expert by any means, I just took Dustin's advice and discussed it with JES.

Jesse's perspective on 3-, 4- or 5-groove was that in his experience one did not offer significant advantages or disadvantages over another. His feeling was that 3-groove would be absolutely fine for purposes of the .338-06. We'll see . . .

I'll have to look tonight, but I'm pretty certain mine is a 3-groove.

Just doing a little reading on line, it seems that there is no clear answer as to whether 3, 4 or 5 groove is better. This is a hunting rifle so I cannot imagine that 3-groove will not be more than adequate.

I know the 1/2 dozen or so animals I've taken with the 338-06 didn't protest any the number of grooves.

I think the groove argument is just the same as button vs. cut rifling, Ford vs. Chevy, etc.
