It looks like a great load for my .338WM and elk, but I wanted your opinions. Thanks. | ||

Not a good load if it shoots 6" groups at 100 yds. Someone else's success is no substitute for your own efforts at the reloading bench and shooting range. However, if you intend to buy the components and then duplicate the load in your rifle, with judicious adjustments in load, overall length, etc., then go for it. The trajectory will do fine.

I think that numbers in inches on the website are the trajectory of bullet. | |||

RIght JABS--I'm saying that you need to test the load in your gun--might not shoot well. My .25-06 shoots W-W 120 gr Pos Exp Pt loads under a half-inch and a friend with the same rifle and caliber gets 4" groups with ammo out of the same box. However, we've worked up a load using Hornady 120 gr HP bullets that shoots 3/4" in his rifle. So, you gotta do the trial and testing unless the load just happens to be spot on for your rifle.

Now I get what you are saying. Yes, I guess I'll try out a box and report back to y'all. | |||

I have been playing with the 338 since 1988, and I have to say it is one of the least fussy rounds to reload. Almost any stout charge of IMR 4350 will yield good results if the load isn't excessive and cases are properly trimmed. Another thing about the 338, almost all available bullets in this calibre are serious hunting bullets. That's something that can't be said about most other calibres, especially those below .30 | |||

I second the 210 Partitions. My .338 Mag spits them out at 3050 fps and .75 MOA. The elk that I've killed with it have dropped like they were hit by the Hammer of Thor !!! The trajectory is also a lot better, only 14" of drop at 400 yds instead of 21" for your listed load. This allows a top of the back hold at 400 yds instead of holding on air.

According to my ballistics calculator they are using a ballistic coefficient of .560 for that bullet. It is no longer on the Nosler website but even the 260 gr Accubond has only a BC of .473. I think those ballistics are grossly exaggerated. For me, it's the 225 gr TSX with 75.5 gr RL19 at 2800 fps. ____________________________________ There are those who would misteach us that to stick in a rut is consistency - and a virtue, and that to climb out of the rut is inconsistency - and a vice. - Mark Twain | Chinese Proverb: When someone shares something of value with you and you benefit from it, you have a moral obligation to share it with others. ___________________________________ | |||

Well, I just placed my order for some and I'll let you guys know how they work. FWIW, I asked the guy from DoubleTap about the ballistic table and he said: "We use a BC of .480 for that bullet per Nosler and the testing is ran a 6,000ft." Which makes sense. When I ran it through the ballistic calculators at www.biggameinfo.com , it made a significant difference when the altitude was changed. | |||

Personally, I prefer the 230 gr FailSafe in a 338. If I was going to use a partition type bullet, I would use a Swift A-Frame. I also like to use a 250 yard zero with a 338. | |||

Just curious, why a 250yd zero on a .338? | |||

This sounds like a real blue darter. The 375 with a 250 only runs about 2750-2800 with more bore capacity and more case capacity and moderate pressures. But the energy/ballastics are impressive. It will sure as hell kill an elk. | |||
