WARNING, MOST OF THIS DATA EXCEEDS PUBLISHED MAXIMUM LOADS. USE WITH DISCRETION.
You didn't say what rifle. If an older Remington auto loader, stick with published max loads, or less.
Most published data for .35Rem is to "Burrito Fart" pressure levels.
My .35Rem loads usually start at published max and go up from there.
Many powders give good results. However, best are H4895, IMR3031, and LVR.
My pet loads are:
#1.
40gr H4895 under a 200gr Remington Corlokt (no longer sold as a component), or Sierra 200gr RNSpt. I seat to cannelure and crimp with a Lee FCD. Gets 2,275fps from my Marlin M336. It will shoot 1" 3-shot groups at my 185yd backyard range. Done it multiple times. However, after 3 shots, barrel will heat up, and poi "walks".
#2.
39.0gr BLC2 under the RCBS 200gr FNGC cast bullet. Likewise crimped to crimp groove. My mold casts to 220gr lubed and gas checked. Cast from 50/50 wheel weighs and plumbers lead, this is a powerful accurate load suitable for anything in lower 48 states up to 200yds. It's running 2,050fps. Noticeable recoil.
Since 2008 and all jacketed.358 rifle bullets being unavailable, I now use this load exclusively in my .35Rem. Jacketed bullets go in the BLR .358win.
A few observations on the .35Rem.
The Marlins have a very short throat. Most suitable bullets seated and crimped to cannelure are very close to touching the lands. This greatly aids accuracy but also requires that close attention be paid to trimming the brass for uniform seating and crimping.
I don't care for the 200gr Hornady RN or FTX. I've had the FTX get the rubber tips get wedged between case head and magazine tubes jamming them in the magazine tube. I've also experienced failure to expand with both bullets. Likewise the 180gr Speer. Both Hornady bullets are accurate though, and available. MidwayUSA has them on sale for attractive prices. However, the Sierra RN is the best available IMO.
Starting out, I'd recommend starting at 36.0gr of IMR3031, work up, with the 200gr Sierra. 38-38.5 is where most users usually find best accuracy.
I had a Rem. M760 in .35 Rem that would shoot clover leaf groups at 100yds at 2,400fps over a full case of H322. This load will "lock up" most .35's so I don't suggest it.
But from a suitably strong action, the .35 will reach within 70-90fps of the .358win. A very underrated and unappreciated cartridge.
