Most likely Berger or Sierra, since Lost River is defunct. Possibly Lapua or Barnes.

The Berger 90 gr Match VLD has a claimed .517 BC - not too shabby.

The Sierra 90 MK has a BC at useful vels of .504:

I have only been able to safely seat 77gr and below and get them to feed out of the mag. So i guess highest BC 77gr and under

OK, then better make it a Berger, Fries, & a Shake...

That 75 gr VLD Berger is .447 - that beats the comparable Sierra MK (77 gr @ .362) & Lapua Scenar (69 gr @ .321) by a wide margin.

Let us know the results please.

You'd probably ought to re-post in the reloading forum on that one....

The 77 grain Berger, BC .389; and 77 grain Sierra, BC .362 are the heaviest bullets I know of meant to load to magazine length; barring the oddball 100 grain that I think was made in the tracer jacket.

There was some work done to convert a magazine to single stack for a longer OAL with heavy bullets, but I think it also required mods to the rifle.

What do you consider "long range" and what type of shooting are you doing that you think you need to run through the magazine?

NRA "across the course" only shoots rapid fire at 200 and 300 yards where the 77 gr is ample. At 600 yards it is slowfire and competitors seat long and single load.

Yeah, but Jim, look at the 75 gr Berger - it has a *higher* BC than the 77 grainer - odd, but there it is.

Folks I know that shoot the Berger say it won't load to magazine length and still function reliably, even if they seat it to the edge of the ogive. You could seat it deeper, but then you can't get the velocity becasue it takes up powder space and has too long of a jump to the lands to be very accurate. I don't know anyone who shoots the Sierra 77 gr. Everyone I know that shoots the heavy bullets single-loads them at the slow fire portions of the range. I shoot the Hornady 68 HPBT gr for every station because they have a high BC (.355), can be loaded to mag length, and still fly good enough for the 600 yds slow fire string.

First: The 77 gr Berger is not a VLD, the 75 is.

Scorch: Just repeating what the Highpower shooters told me. The Army shoots all the 77 gr magazine length ammo they can get... at Iraqis.
Certainly you load long and shoot single shot at 600 yards.

No, I don't load long. Lots of shooters do. I suppose I could, but then I'd have to keep the rounds separate so i don't wind up on the line in a rapid fire string trying to load a mag with rounds that are too long to fit. I'm just too simple, I guess. I know where my rounds are at every point along their trajectory, so any benefit to be gained by seating long is not important enough to me. I still manage to score in the 90s.

Might I be so humble as to propose that you look at the VLD offerings from the Swampworks / JLK Bullets line.....

To shoot a longer than standard bullet, have your rifle rechambered with a shorter case - If you need a tenth of an inch, move the shoulder back a tenth of an inch.

Welcome to the world of handloading hell...

Nice thought, except most folks don't want to shoot a wildcat in NRA or DCM shoots. Or a 222, or a 221 Fireball. You lose velocity, which will hurt at 600 yds.
