This is my first time loading for the .350 RM and I'm sending it through a 16" bull barreled XP-100 I bought from tclubber here at the 'fire last winter. I thought recoil would be wicked with this thing, but due to the stock design and weight of the barrel it's more of a slow roll of recoil up and back. The only .35 caliber bullets I have are the ones I cast - 190 gr. Ranch Dog LFNGC and a 215 gr. NOE LFNGC and a bunch of Speer 180 gr. HotCor that I've been using in my .357 Maximum TC Encore barrel. Cast bullet results weren't terrible - best group was 1.25" at 100 yds with a stiff charge of 5744 and the best 180 gr. Speer load is 57 gr. of XBR 8208 that gets me 2400 fps 10 feet off the muzzle and puts five shots in an inch at 100 yds and I took apart a bunch of 6-8" diameter pumpkins at 250 yards on Tuesday afternoon. I plan to use that load for deer in January. I don't have a lot of powders in the burn rate class that work well for the .350 RM. XBR 8208 was extrapolated from .35 Whelen data. I also have RL15, Varget, and H380. 58 gr. H380 also got me excellent groups and 2400 fps. Should I be looking for some Hornady 200 gr. Interlocks for this or will the 180 gr. Speer hold up? I'm running them at 2050 from my .357 Max and have yet to catch one in a deer. Hopefully they're stout enough to take another 350 fps. Where I'll be setup it looks like shots will be 100-250 yds, so it will have lost some steam by then. Other powder suggestions? I've got 8 pounds of H380, a pound of RL15, and less than a half pound of the XBR 8208. My first loads with RL15 yielded acceptable groups at 100 yards, but I haven't put them over a chronograph yet. Finding published data for .350 RM and 180 gr. bullets is hard, but there is some out there. Other powder or bullet ideas? I don't think the 200 gr. bullets will make the recoil unpleasant, but I won't know until I try. It's a lot of fun to shoot! Selmer

I can tell you that the 200 Hornady spire point works like a champ out of a rifle when started at 2600 fps. I had one go through a inch and a quarter grape vine that I didn’t see as a buck trotted by about 40 yards away. The bullet broke both shoulders and ended up under the skin of the far shoulder. .

Finally found an online published source that has the data I need. Looks like I need to find some H322 to feed this thing for max efficiency and velocities.

I shot the 350 Rem Mag for over 40 years. Here's my most accurate loads for my 600 - these are all five shot groups - most averages of multiple groups.
350 RM, Remington 600, 250 grain Hornady Interlock SP, 9 1/2M, 57 grains WW748, 0.66 MOA 350 RM, Remington 600, 250 grain Hornady Interlock SP, 9 1/2M, 53 grains H4895, 0.71 MOA 350 RM, Remington 600, 250 grain Hornady Interlock SP, 9 1/2M, 55 grains WW748, 0.80 MOA 350 RM, Remington 600, 250 grain Hornady Interlock SP, 9 1/2M, 55.5 grains IMR4064, 1.22 MOA 350 RM, Remington 600, 250 Speer Hot Core, 9 1/2M, 56 grains IMR4320, 1.33 MOA 350 RM, Remington 600, 225 grain Nosler Partition, 9 1/2M, 56 grains, IMR3031, 1.77 MOA
The 250 grain Partitions as I recall the Inerlocks and the partitions were interchangeable for accuracy and POI (but I cannot find the data). I sold the partitions to a guy in Alaska through 24hourcampfire classifieds forum.
The load I settled on was the 53 grains H4895 and 250 grain Interlocks. I found that the WW748 was temperature sensitive. The 250 grain interlocks were all that was needed, IMO.
I used magnum primers as I found standard primers sometimes left powder in the barrel.
I didn't try loads under 225 grain and the best load I had for the 225 grain is listed.

you will have trouble burning all the powder in 16" barrel I shoot 58.5 gr of 4064 Hornady 200gr SP out of a Remington Model 7 with a 20" barrel

Selmer, Here ya go... https://stevespages.com/358_3.htmlyou ought to find something in there for your needs.. bunch of info with a with variety of bullet weights. With the barrel length you've got, not sure of the distances you plan on shooting at, but I'd consider using 358 Winchester load data, or even 35 Remington with 4198, either one, or RL 7. Sounds like quite the kicker with a 16 inch barrel, while pushing 50 to 60+ grains of powder Even 356 Win Data with the 4198 or RL 7. Never really had any interest in the 35 caliber cartridges until I shot one down in New Mexico at a Campfire Get Together. with 200 and 220 grain Speers, loaded with RL 7. I was impressed with the low recoil level, yet the accuracy of it, breaking rocks at 200 yds. 3031 would also be a powder I'd look at or AA 2015. Thtat 358 never sold me on a cartridge so quickly.

I load for a good friend’s .350 Rem Mag. It shoots 48 grains of Reloder 7 and a Hornady 200 grain Spire Point quite well.

Steve’s pages is one place I went for data, but I never know how much to fully trust the info there. After I had done the initial load development and decided to then run over a chrono, I loaded up 15 extras of the 57 gr. XBR 8208 to dial in for deer hunting. I anticipated 2400 fps and wanted a 225 yd zero, as that’s about as far as I can see to shoot where I’ll have the blind. We had Grace practicing with her .357 Max before she heads back to college and then comes home to hunt over Xmas break. So we gathered a bunch of frozen and then partially thawed pumpkins to shoot after verifying on paper. Her TC and Leupold 2.5-8x32 handgun scope held perfect zero from last year, so she shot a few pumpkins at 150 yards. Then after I zeroed at 3.5” high at 100 I set pumpkins out at various ranges and proceeded to smash every one and then smash visible pieces with my XP100. We were shooting at a parishioner’s place and her brother was here from Colorado for Thanksgiving and clearly wanted to shoot, so I offered. His handgun experience was limited to revolvers. He dry fired it a few times and then wanted to shoot. I told him to center the farthest pumpkin and see what happened. I watched him blow the back out of an 8” pumpkin and he looked at me with a grin on his face and asked if he could shoot some more. I let him try to take that pumpkin apart because it was still standing. He kept shooting with no visible impact so we walked down. He had stacked five shots in the center of the pumpkin and made a hole he could stick two fingers through. “I’d never thought a pistol could do that.” We walked back and he asked if he could take the top off of it. “Sure.” He put the bullet right where it belonged and blew the top into the air about ten feet and he watched it fall, laughing. I’ll have zero qualms about shooting at a deer at 250 yards with it and could probably stretch to 300, but no place there allows for that distance. I’m hunting the edges of timber that open onto corn and bean fields. We’re about two miles west of the Mississippi River in great Iowa deer country. My ground blind will be at the edge of the farm yard, which is one of the higher points that gives us good visibility in all directions. I’m excited to deer hunt this year.

I've used the 350 Rem Mag for about 10 ~ 12 years. Until this year it was only for black bear. I used to use the Hornady 200 gr. SP/IMR4320, but switched to the 225 gr. Sierra SBT. I used it for deer hunting this year, and all went well. Bullets are harder to find than other calibers, but I can get enough for hunting.

Of all the newer powders Reloder10X works well in my Rem 700BDL 350 Rem Mag with 24"bbl
58gns H4895 & 200gn Hornady.......2762fps 56gns RL10X & 200gn Hornady.......2851fps
The above velocities are a 5 shot average.

I've used IMR4320 under 250s and 225s with good results. I've just started playing with TAC now and it does show some impressive velocities under the Hornady 200 SP Interlocks. The Barnes guys list it for their 200 and 225s with 2900+ for 200s and 2764 with the 225s. A big plus for me is that's it's my favorite .223 powder for my 3Gun loads so I'm sitting on 10lbs of it.

Tac is the king for velocity of all powders I’ve tried. 200 gr barnes using their load data 2700 fps in an 18” barrel at pretty much the starting load. They claim 2900 feom a 20”. I was getting 2700 with a max load of R17 and 26” barrel. Same bullet. Not sure how it would work in your barrel.
