With a 300 win mag step up to the 190 or 210 grain LRAB to take full advantage of the cartridge. I wish I could go with a bigger grain but I can't. I have an A-Bolt Browning in 300 wm and the detachable magazine FROM the factory is so short I can't load a longer bullet. It either won't fit into it or its so tight it will flatten the nose of bullet when shooting. Don't have any idea what the he ll Browning was thinking when the designed this. I tried to adjust bullet depth when I first got it so the round was closer to the lands trying to get better accuracy and that's when I discovered the problem. I have loaded 180's but I have to watch how far I seat them. Just seat the bullet to mag length and tune your load from there. Yeah you loose a little case capacity and velocity but you more than make up for it in retained velocity, wind drift and energy at longer range due to the heavier bullet. Seating to mag length is the name of the game with most magnums and heavy bullets if you want it to be a repeater hunting rifle. Just because the bullet has a lot of jump does not mean it won't be accurate.

This makes sense. Litz tested G1 BC for the 168 LRAB is .624 while the Berger G1 BC is .617. At 800 yards with all things being equal there should be about an inch difference between the two in drop.

Wow great deal on some awesome glass. Good luck on the sale.

I sure don't. Ive got data where he has tested just about every thing but the .284 cal Scenar. Given the fact that Lapua has recently upgraded the way they do their ballistics testing with dopler radar to determine very precise drag coefficients along the bullets trajectory I would say that their advertised numbers are very close. Doing some quick calcs with the Lapua 180gr in 7mm I come up with a drag coefficient of .963 to achieve the advertised G7 BC of .331 which is very believable. The Formula: 180/7000 = .0257 .0257/.284 squared = .3188 (Sectional Density) .3188/0.963 (Drag Coefficient) = .331 G7 BC

Try not even close. .625 advertised vs .543 Litz measured actual. The .277 150 is actually the most over estimated over any of the new long range accubonds.

Gone.

The Barnes bullets are pure copper resulting in a longer length for a given weight and more bearing surface. Add all that together and you got yourself more fouling.

Most impressive group there lance. Did you do any break in on the barrel at all? only reason I ask is that when breaking in a barrel I have seen groups with similar results with groups starting around an inch and end up about half that with the same bullet and load by the time break in is over. I have a large target with multiple aiming points and I will start shooting from right to left top to bottom and literally watch each group shrink in size from dot to dot.

Not near enough gun. Only a .338 Lapua with 300 grain bullets is capable of taking elk outside of bow range. Just kidding, a 7mm Mag and 150s is more than plenty to tackle elk. Good luck on the hunt.

Not shooting one but I am sure it would work great. Brass for the WSSM cases are getting quite difficult to find these days, if you don't already have a supply of brass you might look into the 6XC for another option. Brass is easily made from .22-250 cases and definitely different.

+1 lance we have all had animals that should have dropped dead on impact but the truth is that's not always the case. Heavens knows I have seen some coyotes run off deader than heck with a hole through them big enough to see through and others drop like a rock on the spot.

I am a firm believer in hitting bone with the Bergers especially on a small coues, gives the bullet something to work with and allows it to open up like its supposed to. They are designed to open up 2-5" after penetration, that can be 3/4 of the way through a coues deer before it even starts to open up if hitting soft tissue. The way I look at it is if I hit shoulder bone and for some reason have a bullet failure I still have an animal with a broken shoulder and he's not going far.

By the looks of that shot placement I would have to chalk that deer living so long up to sheer will to live. I would try the bergers again before writing them off completely because of one incident.

I'm with lance. 115 berger is the best there is. By far the best ballistics of any 25 cal bullet made and awesome terminal performance. Prairie dogs to elk the 25-06 and the 115 berger got you covered.

Second Amendment sports had tons of primers when I was there last weekend. Powder was pretty sparse except for IMR 4064. Sportsmans didn't have anything other than IMR7828, IMR4895 and H50BMG. Again this was all last weekend so things could have changed but I struck out. Good luck.

Fact of the matter is velocity probably plays the smallest role when it comes to stabilization. Its all about the length and shape of the bullet. The more stable a bullet is the more optimized the B.C. and while velocity does help its only a small percentage when compared to other factors that determine the stability of a bullet. Temperature and elevation are much bigger factors than velocity. For example, using Bergers twist rate calculator and running the numbers for the 230gr Match Hybrid in standard conditions being 59 degress at sea level the stability factor is 1.51 at 2650fps and only 1.64 at 3400fps. Run these numbers again at 75 degress and at 3000 feet elevation and you get a stability factor of 1.74 at 2650fps and 1.89 at 3400fps a much bigger difference. This particular bullet is still stable down to 1000fps with a stability factor of 1.1 in standard conditions but the B.C. is reduced by 12%

Seems to me you already got it figured out. The .25-06 worked fine last time why not use it again. No need to reinvent the wheel or waste money. If you really just want to spend money upgrade the optics.

128 5/8

Chances are the bullet isn't the problem. Have you tried a different powder or primers? Is the rifle bedded and barrel floated? In my experience if the bullets in the green box (Sierra) don't shoot you got a problem somewhere. If given the choice though I will always choose a Berger over anything else.

The two deer I have seen them used on exited but massive internal damage was done. One deer took three steps the other fell where he stood.

Amax works extremely well especially at long range. I have had solid results shooting them in a 6.5 120gr and 140s.

You say you have less than half a box of ammo through this rifle? Any particular reason you took an un-proven rifle on a possible once in a lifetime hunt? I am not trying to bash you here as you were obviously successful in your hunt and good for you but how certain of that rifle and ammo combination are you? Was this rifle sighted in using the Bi-pod or simple sand bags off a bench? How many groups did you shoot and what size were they? Did you have consistent high flyers? Lots of things to consider than simply chalking the success up to the magnum cartridge which is only doing 200fps more than the standard cartridge.

Darn you Lance! Good pick up buddy.

Runners is why I quite using a .223 for Coyotes. I don't care about pelts so I steped up to my .250 Savage running 115gr Bergers at 2850fps. Needless to say the runners stopped. As far as dies go contact just about any die maker and the should be able to make you a set. MidwayUSA shows an RCBS set available and in stock currently.

I don't have a .284 Win. But it will definitely be to long to work in a standard short action with the heavier bullets. My 6.5-284 has a C.O.A.L of 3.214" with a 140gr Berger vld, the .284 will be every bit of that with 168s or heavier im sure. Your best bet for a 7mm cartridge would probably be the 7-08 Improved as mentioned above. A custom rifle in a 6mmXC would make an outstanding long range deer rifle and on my list to do. .243 Ackley 6 Creed Even a fast twist 22-250 improved able to handle an 80gr bullet would make a sweet rig too.
