From Hodgdon (I suspect 24 inch barrel, too short!) 7mm STW- 160 GR. SFT SP Hodgdon US 869 .284" 3.565" 85.0 2922 46,400 CUP 90.0 3041 50,800 CUP 160 GR. SFT SP Hodgdon H50BMG .284" 3.565" 88.0 2929 46,100 CUP 90.0C 2970 46,600 CUP 160 GR. SFT SP Hodgdon...

SS- I don't see where there is a problem. Your load is shooting 1.5 MOA or less. This has been common for me with NP's. Shoot a few groups with 5-10 rounds to make sure. Remember, an elk is minute of pie plate. Some thoughts: Your 56 grains of IMR 4350 is 1g high according to Nosler #6...

Supposedly, Nosler did not include the 7mm RUM in their #5 because they could not get realiable/consistant pressures. Might have been that they were trying powders that were too fast. Seems they worked it out for #6. To get a good comparision between the 7mm STW and the 7mm RUM, take a...

One of the "best" rules I have found to live by is 1 gun, 1 load, 1 job. If for some reason you need another "job" done, you buy another gun. Works for me. :grin:

Of course, different reloading books vary on their recommendations. They were shot from different rifles/barrels. However, if its recent data (within about the last 10 years) in those books, all have been well pressure tested. QuickLoad is just a programers scientific wild a$$ guess. For...

Got Nosler #6? 160g AB, max RL22 - 63g 150g PT, max IMR 4831, 65g, about the same for RL22. YMMV.

Go with a non-temp sensitve powder. Take a look at Hogdon's site for H1000 and Retumbo.

223, 40g BT or V-max, VVN120, 3800fps. See Nosler #5 or #6.

Several of us want a 300g AB for the big 338's. Just saying, again.

It works well in my 7mm Remmag with the 160g Accubond.

It does not matter if one is a good shot or a bad shot because one is not aiming at the coin! YMMV. :wink:

Pop- Thanks for the info. Where did you come up with an OAL of 2.430? Nosler #6 has 2.350 and my rifle is 2.487 for .005 off the lands. Oh well. Funny that H4831sc and IMR4831 did not show up in your data. They are listed in #6 for the 60 grain Partition at 95% and 93%. ETA: Pic below...

Since Nosler has yet to have any loads for the 22-250 AI and the 60 grain BT in their on-line database, let me offer this. RL22; 44-45 grains, CCI 250 primer, for 3525-3550 fps (26 inch barrel, 1:12 twist). Happy varminting!

+1 Only to add: SD only applies when comparing bullets of like construction; lead to lead, copper to copper, Partition to Partition, etc. ETA: Once you reach full penetration as in a high speed Barnes, Failsafe or E-tip pass through, your only concern should be a not too short blood trail...

Whatever!

Exactly my point above! To get the most out of the high speed, heavy bullet 338's, most would NOT want a rifle light enough to carry. You would want to bench it. 8)

Thanks for the article!

Just FYI: The guy I mentioned, Ray Weller, is building an EDGE with a 36 inch barrel tying to break 3200 fps with a 300 grainer for elk hunting at a max of 1500 yards (he is in a wheelchair). He has been begging Bob Nosler for an AB in that weight for a couple of months. His alternatives are...

I think we agree for the most part. A 338 Lapua, Ultra or EDGE rifle firing a 300g bullet at 3000-3200 fps SHOULD not be a carry rifle. It WOULD kick the snot out of most including me (I'm a wuss). Higher rifle weight, a rest or bench and a break are the easiest ways to tame it. BTW, I...
