Speer #11 manual shows loads for Speer 140 gr bullets in the .357 max. May have to adjust downward a bit to start, if Barnes bullet is pure copper and longer bullet with deeper seating.

H110 24.5 (2031, 26.5 (2177)
IMR4227 23.0 (1869), 25.0 (20.38)
2400 20.5 (1867), 22.5 (2058)
296 26.5 (2116), 28.5 (2258)
Loads were developed in 14" contender 1:14 twist.

For the Barnes products get the data from Barnes only unless the powder company is using that specific bullet for their testing. These bullets are lighter for length than lead and thus have different internal ballistics than other bullets. The shop where you bought the bullets should have the Barnes literature, if not get on the web and check their website. If it's not there e-mail them.

I have already talked to Barnes about the 357 Max and a the 35 Remington, they have no data on these two rounds.

If your T/C has a long throat, no problem, simply measure a regular 357 140 gr bullet from base to cannelure and seat the barnes that deep or less and load em up. As long as not seated deeper the only thing that matters is the weight. In fact, my .357mag barrel for my T/C was so long throated I bought bullets with the double cannelure and seated them out to near .357 Max length and worked up a load much hotter than you can for the magnum length. Not quite Max but I can sure understand someone
wanting that cartridge in a contender, what a hoot.

My chrony was broken, but I could sure tell the increase in power in the palm of my hand. And no sign of excess pressure. Your mileage may differ. :D

Do you have the reloading data for the 35 Remington, I shoot this in my Marlin 336 and in one of my contenders.

Thanks for your advice and help,

I do at home, I won't have access to it til after 5:00pm. If no one has posted a good sample by then, I will consult my manual.

By all means measure where the canalure (sic) is and compare to the 125 and 158 gr bullets for the 357 max. It should be a fairly easy load trial. Depending upon the OAL, I'd start with the beginning loads for the 158 bullet and go from there.
In my experience Barnes is often a little higher than other reloading manuals for like weighted bullets, probably because their bullets are longer for weight than traditional lead based bullets. The absence of load data per Barnes is no problem. You're dealing with a straight walled cartridge with known bullet weights, and has been mentioned, Speer and others have data for that weight. I dont' know why the 35 Rem was mentioned in this thread. Don't use 35 rem load data for 35 max, not that you were.

.35 Remington for the 14" barrel Contender Speer#11 Manual.
No load data was worked up for the 140 grain bullet weight range in the contender, but was for teh Marlin 336 (data below). It starts at 180gr to 220 gr. for the contender data. You can use the 180 gr baseline info, compared to the rifle 140 gr info below, to start and work up from there if using the 140 is your goal for a contender.

180 grain bullet
748 40.0 (1714) 42.0 (1879)
IMR4895 38.0 (1789) 40.0 (1896)
IMR3031 36.0 (1734) 38.0 (1837)
H335 36.0 (1871) 38.0 (2023)
H322 36.0 (1825) 38.0 (1997)
BLC2 33.0 (1736) 35.0 (1885)
IMR4198 28.0 (1683) 30.0 (1808)

Loads for Marlin 336 20" barrel show bullets from 125gr to 220 grain with 125 to 158 being .357 pistol bullets. This may help in cross extrapolation and load workup, perhaps using the powder common to both tables. IMR 4895.

140 gr bullet
IMR4895 37.0 (2011) 39.0 (2131) 41.0 (2255)
Reloader7 36.0 (2247) 38.0 (2392) 40.0 (2539)
680 26.0 (2007) 28.0 (2162) 30.0 (2334)

Corresponding loads for the 180 grain for the Marlin are the same as posted above for the contender but with slighlty higher velocities due to the 2" longer barrel.

Hope this helps in working up a suitable load.

PS: for the rifle, watch overall length for cycling in the action.

Sierra has two pages of data on the 357 Maximum (170-200gr) and two on the 35 Remington (158gr-200gr). These pages are available from Serria and I would suggest you get them. Both sets of data were shot in a 14" TC Contender.

Note: The Serria manual is a loose leaf binder, individual page sets are available.

I picked up a hard back speer reloading man.#13 at cabelas which is on sale for about 10 bucks right now, and has loads of info in it (haha).I used the 357 max info to try a few loads.They use speer boolits but I used remington & hornady and came up with some real good loads.I'm pretty sure it has 35 loads indeer to.Good shootin.
