Hey guys looking for some recipes for a 338 RUM with a 210 grain partition,

I dont have the Nosler reloading manual yet, but there website lists the load data... Wondering what I should go with in concerns with powder, they list H4831sc, IMR4350, IMR4831, and H1000. Just wondering if anyone has reloaded this caliber out there and what they found to work best with there gun. Oh and its a Remington 700 XCR with a 26" barrel that there coming out of. I realize that not all guns are the same and everything needs tweaking, just wondering a good starting point as in which powder etc.

Thanks!
 
I agree with the heavier bullets. That caliber is kind of a waste of time with the 210's as the .300 Ultra and 200 grainers get you a better BC and sectional density. Life really starts at 225 grains with the .338 Ultra and H1000. My choice in that weight is 225 grain Accubonds and a max charge of H1000. Accuracy is great and it is good for 3150 fps or so out of my Rem 700 LSS and a 26" barrel. I recently have been trying 250 grain TSX's with Retumbo. Velocity is not where I want it, so I may be returning to the Accubonds.
 
Okay, I have no problem upping it to a 225 grain bullet, what bullet would suit best though? Is the accubond just as good as the partition penetration wise? Just with better flight characterisitcs?

Im not stuck on nosler bullets by any means, just want the best performing bullet for this caliber for hunting. All Ive ever shot out of this gun is federal ammo with 225 grain accubonds and then handloads made by my buddies dad which were the 210 grain bullets.

Definately not opposed to change anything, just got into the reloading as stated before and want a good combo bullet weight/powder to start from. I didnt know the 210's were not a good choice for the caliber, just sort of learning on the fly here lol

Thanks for the advice!
 
I have shot a moose and 3 deer with 225 gr Hornady Interbonds and they worked great every time. I recovered the bullet from the moose because after about 2 feet of travel through the animal the bullet ended up in the spine in the neck, expanding to 0.800" on the wide side and retained over 75% of it's weight, an excellent bullet for the price IMHO.
 
I've been looking at the interbonds, they seem much the same as the nosler accubond bullet?

Also have done some reading on the net on various sites and a lot of guys are apparently using the 225 NAB and loading with RL-25 powder... Anyone have any experience with this? Seems the more I read about bullet selections and powder the more confused Im getting with the choices lol

I think that the Interbonds and Accubonds will perform much the same. I only have experience with Accubonds in .338 RUM, but have used the Interbonds in .30-06 and they have been fantastic. Can't speak to RL-25, but I know that H1000 is fantastic. Everyone I personally know that shoots this caliber uses H1000 or Retumbo and Accubonds. I am sure that there are some other powders out there that do well too.
 
Okay thanks! I'll be getting some accubonds, now just have to decide on the powder... Theres lots of reviews on the net for both H1000 and Retumbo just not sure what to go with yet.
 
Nosler 250 gr. Accubond with 100 grs. of Retumbo, CCI 250 primer, 28" barrel, 3100 fps, accurate. This is a max load in my rifle even though its 1 gr. under Hodgdons max load.
 
Okay so another question... I finally got my 225 accubonds on the other night so I sat down and reloaded 1 of them tonight and encountered something, not sure if its a big deal or not or normal but I figured Id ask before going and blowing something up.... I decided to go with Retumbo powder, the manual says starting load is 97 grains, I poured this into my sized and primed case and then went about setting up my seating die... Heres where the question lies, I measured the chamber in my rifle, then went to the manual and looked at the max C.O.A.L. then measured my magazine, what I found is that basically the max bullet length (measured overall length not using comparator) is 3.6", this gives a little room at the end of the magazine for easy feeding. So I went to set up the seating die to obtain the 3.6" and everything was going good up until I heard the sound of the bullet "crunching" the powder. This somewhat concerns me as the manual does not state anything about the starting load being a compressed load. I know 100% that I have the powder charge correct as I dumped out another shell and measured how many grains of powder. I've only made up 1 shell so far and figured Id ask before I go and do anything else. The shell that I made up is 3.6" long which is exactly what Im going for.

Has anyone else experienced this? Is it something to worry about?

You are going to have to deal with compressed loads in this caliber. I use a homemade drop tube and tap the case a bit to get everything to settle down and it does make a difference when seating the bullet. Your mileage may vary.
 
Okay perfect, just figured Id ask the question to see if this was normal or not... I know on some other reloads I had made up by my buddies Dad, he used H1000 powder with the 210 grain partition and they are not compressed at all, you can clearly hear the powder when you shake the cartridge, this is what made me kind of leary about the retumbo and the compressed load.

Theres room for the bullet to seat for sure, its just that last tiny little bit you hear the powder "crunching" I cannot believe the amount of powder behind these bullets! Lol
