You need to shoot a series of groups, five or ten shots each, to evaluate that load.

I finally got around to pushing the 3031 charges up beyond 39.5 grains with a 168.

I used Federal brass, Remington 9 1/2 primers, Nosler 168 gr. match bullets, and 41 grains of IMR 3031.

Overlaying the two, five shot test groups produces a composite ten shot, 2" group. That's at 300 yards, so the load definitely has potential.

That's really fine!

Is it from the Brux on the Stiller?

It is. Seems like lately that it likes everything I put through it.

John, I've noticed your 308 brux was good from the start but it really started to sing after a few hundred rounds down the tube.

I can say that with a 6.5 pound rig all up shooting max 190 grain loads, recoil does get your attention after a bit...grin...

RL-17 - topped out at 2,550 or so. Accuracy was bad, all over map.

RL - 15 -topped out at about the same velocity as RL-17. Accuracy was better. Didn't get to the high node, low node was at 2,450 to 2,500, too slow.

Big Game - topped out at 2,575 or so. Accuracy was so, so. Likely will not pursue further.

TAC - topped out at 2,625 or so when bolt lift started getting a bit heavier. Accuracy was great. Hit high nodes between 2,575 and 2,625. 4 shot group with a 1.5 powder charge range (range may be higher but hit pressure) went into a bit over 3 inches at 300 yards. I am going to play with charges and seating depths but I think there is a good load in here in the 2,600 range -

PS - I can provide charges if anyone interested.


The TAC load that showed promise during the ladder fell apart at 400 yards.

6 to 10" groups...back to drawing board and I retract my good .308 load above...grin...

Maybe you folks could give me some advice. My b-in-law and I have several rifles of various brands (Rem,Ruger,Win,Sav,Wby Van, etc.)in standard big game calibers. We have been able to tweak loads and get good consistent 1 minute accuracy out just about all of them. B-in-law bought a Mod.700 26" heavy barrel .308 that will shoot a 2" 3 shot group at 200 yards only occasionally on its best days. Usually much worse. The magazine won't handle much over a 2.815 COAL round. To get a Nosler 150 BT to touch the rifling takes a COAL of 3.000. Is this acceptable? Can this rifle be expected to be accurate if the projectile has to almost jump out of the case to engage the rifling? By the way, the Nosler BT is its most accurate hunting bullet, 168 MK maybe a little better.

I would check the bedding first. There should be enough clearance between barrel and stock for a business card to pass freely. Other things to try would be checking the rings and bases to be sure a screw or two isn't loose, and then check the action screws. I usually shoot Savage rifles and they are famous for needing a thread or so taken off the screws to keep them from bottoming out. Also the scope could be part of the problem. If possible substitute a known good scope and try again. And check to be sure the recoil plug is not bottoming out.

Good stuff. In addition, make sure the mag box is not binding. With the floor plate down, you should be able to reach in with your fingers and move the mag box a little. There should be a little float. If not, it is likely the box is a little too tall, causing the action to flex around it. Make sure the scope base screws are not too long thus pushing on the barrel shank.

I shoot several heavy barrel 700 Remingtons in 308 Winchester. With 168 grain Sierra Match Kings or Nosler Custom Competitions set to magazine length, they're jumping roughly 1/8" to the lands. Nevertheless, 2" five shot groups at 300 yards are common.

So no, jumping them isn't necessarily going to be a cause of inaccuracy.

has anyone tried the 165 grain speer bullet with the .52 b.c. It appears to be just a cup and core but it does seem to have a really good b.c.

I tend not to believe Speer's bc figures. For example, the one you're asking about is supposed to have a higher bc than a 175 grain Berger VLD. Suuuuure it does.

I'm with Mathman on this. There is no way a 168gr BTHP Match, from anyone, is going to have a BC that approaches that of the Berger 185gr VLD. Not happening. Yet that is what Speer is claiming…

45gr R15 behind 155gr Bullets seems to be a good accuracy node in my rifle. Two different bullets, two different cases, two different primers but the same powder charge produce great accuracy for me. These are 10 shot groups.

John,

If you want a really easy shooting practice load, try close to 40 grains of IMR 4064 under a 168. Maybe a couple of tenths less in your shorter throated rifles would be better.

Out of my 5R Milspec I've put twenty into .85" at 100 yards with thrown charges. It's gone .52 MOA at 300 yards for seven shots as well.

Just got back from the range today. In my .308 M70 fwt:
44.3 gr. of Varget,
165-gr. Hornady BTSP
Fed. brass
CCI 200
COAL - 2.810


0.4" at 100 yds, velocity in 22" barrel - 2726 fps. I'll load some more and test further at 200 and 300, but I think I have a winner.

I just got some hornady cases and 165 grain interlock boat tails. Are these bullets a good multi purpose deer, bear, and slightly longer range target bullet?

I have
748
blc2
2520
varget
reloader 15

where do I start
