I am working on a couple 350s. I have read a couple places that RL15 is the way to go, and I have some of that on the shelf, but I am having a hard time finding any data for it. One website I found talked about 52-54 grains max and anther the guy is running over 60 grains! Folks have said use 35 Whelen data, and I beleive the Nosler book states 55-59 grains. I guess I am just looking for a start load, is 55 okay? Anybody have any specific recipes? I have Sierras and Nosler Accubonds, both of which will fit into my magazines no problem. | ||

What bullet weight do you plan to use? I have a Rem. 700 Classic in .350 Rem. and have had good luck with 56.0 gr. of IMR-4320 and several 200-220 gr. bullets. This is not a maximum load but it is accurate and kills deer. I would use data for the bullets you want to use, i.e. Nosler data with Nosler bullets. About the most accurate bullet I have used is the 220 gr. Speer FN, but it is a little fragile and can damage a lot of meet. The 225 gr. Nosler partition also shoots well in my rifle. | |||

As I always say; NO one can give you a load; no one. Your rifle and components are completely different from anyone else's. I have 4 350s and have built a few more. I always make them on long actions, and have a throat reamer, so I can seat bullets out and use that powder capacity, so any load I "give' will not be germane. Or it might. My fav is a Ruger 77 tang safety in a boat paddle stock. Yes, it can be done. You would not believe the loads if I told you and I do not want others to even try them. Too many variables. Now if you just want to fling bullets, pick a starting load and use that. You will have to work up your loads, like for anything else. | |||

Yup, I agree with that comment dpcd, but I am having trouble finding published data for 350 Rem Mag and RL15. I plan to use the 225 SMK and 225 Accubond, both will work in this rifle, I have already checked. My best starting point right now is about 54-55gr RL15 based on Whelen data. I was just hoping somebody could confirm I am on the right track. | |||

257, You might want to rethink using 225 Accubonds in your .350 RM. The bullet profile doesn't work well with the standard chamber/magazine dimensions. That's why Nosler specifies .225 Partitions instead. In fact I think they mention it on their website.

OP, 57-58gr of IMR 4895 pushing Sierra 225 SBT will run circles around 4320 or RL15 in accuracy & velocity...at least in my 1/2 dozen Rem 700's,660,XP-100R in the last 40yrs. | |||

Nosler lists 55 grains of RL15 with a 250. With regard to bullet profiles and magazine compatibility; that is why I always build them on long actions. It is a waste in a short action, although I do have one. Just for fun. | |||

I have a pair of the old Remington model 600s; one in 6.5 and the other in .350. My loads are as follows: 200 grain bullet, 55 grains of 3031 250 grain bullet, 50 grains of 3031 Simple, works for me, and both loads have killed several caribou.

For my rifles, I actually use only 3031; load it like black powder and it works. Stuff as much as you can and seat the bullets out. I get velocities you wouldn't believe. Do not try this method. | |||

I could find no data published by manufacturers for RL15 and 225 grain bullets. Here is the data for RL15 & 250 grn bullets that I have found: Nolser 51.0-55.0 grains Steves pages* - 46.1-57.3 *This data is not lab tested A quick load run that was published - 49.9-53.9 Since, you didn't get a 350 Rem Mag for its velocity characteristics, I would do the following: Load 1 round at 51.0, 51.5, & 52.0 to check for pressure/safety Load 4 rounds at 52.4, 52.8, 53.2, 53.6, & 54.0 and shoot round robin on individual aim points and look for your accuracy node. Mike Legistine actu quod scripsi? Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.  What I have learned on AR, since 2001: 1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken. 2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps. 3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges. 4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down. 5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine. 6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle. 7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions. 8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA. 9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not. 10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact. 11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores. 12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence. 13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances. | |||
