The only time I've seen loads with primers backed out and no other symptoms were present was when the pressure was under normal operating pressures. High pressure does not leave primers backed out. It can either flatten primers or loosen the pockets to the point that the primer will just fall...

It depends on what you're using the rounds for. If you're just target shooting, where you are simply loading the ammo in the gun and then shooting it, your seating depth should be okay. If you're using the rifle for hunting, where the ammo may be in and out of the rifle several times before it...

A 165gr bullet would work fine, but I prefer to use 180s. The whole reason I bought a RUM is to push fairly heavy bullets at high speeds, so to me, light bullets just don't have much appeal for such a cartridge.

Definietly go with Magnum primers. The CCI BR-2s are fairly mild even for a standard LR primer.

Right now I'm using an RCBS press and scale. As for dies, various tools, etc, I have a mix of just about everything, but RCBS and Lee make up the majority. I've been loading for 7yrs. A lot of people on the net are kind of surprised to find out that I'm just 23, so I haven't had time to be...

I seem to be brand loyal when it comes to rifle powders. In the last 2-3yrs I've come to prefer Hodgdon's "Extreme" line of powders, as they really do seem to be more tolerant of temp changes, so I generally try to use one of them if the burn rate will suit what I'm working with. With pistol...

Here's a good free online ballistics program... http://www.eskimo.com/~jbm/ballistics/traj/traj.html

There's an endless assortment of variables that could account for the differences. They data was tested by different people, on different days, with different equipment, in different barrels, with different components, with different lot numbers of powder and so on. The things that immediately...

The calibers I load for are always changing as I buy new guns and get rid of old ones, but at this point in time, I'm loading... 308 243 300 RUM 454 Casull 45 Colt 44mag 357mag 38 Special 9mm I still use some factory ammo in rifles that I don't shoot very often and don't require extreme...

Did you examine the wound for any sign of a destabilized/tumbling bullet? My theory is basically the same as NOSLER1's. You got wood which damaged the nose portion, destabilized the bullet and resulted in the rear core getting squirted out due to the bullet not hitting straight on. The...

My thoughts exactly. If you're just starting out, I would stay fairly close to the manual's recommended OAL for a given bullet weight. After you get more experienced at the loading process and tuning a load with different powders and bullets, then you can worry about altering the OAL to better...

It sounds like the load is just too light as mentioned above, and it is toward the lower end according to most data sources. There's no real danger to that though. Usually when you have a headspace problem, the primers will end up getting flattened, making you think you have high pressures...

155gr and 168gr

I would go with the 100gr Partition for deer. The 95gr Ballistic Tip will work too, but since the 243 is toward the small end of the spectrum for deer, I prefer to play it safe and go with the 100gr Partition. As for the 55gr BT on coyotes, I haven't tried it. I use the 70gr BT for coyotes. I...

I haven't read the article, but it sounds like Barsness was getting at the same thing I said above, . Modern centerfire cartridges in modern rifles generally operate around 60k-65k PSI. Well, at 65k PSI, if everything with the rifle is okay, then you won't have the traditional pressure signs...

Except for the the Palma shooters who're using 155s, the vast majority of long range shooters (F-class, tactical comps, and the weekend hobbyist) seem to be using 175s in the 308 and 190s in the 300 Win mag.

Is it a drastic POI change or just a couple inches at 100yds, and does the POI seem to come back to where it should be after several rounds have been fired? I see people all the time who sight in their rifle, and of course the barrel has a decent amount of rounds through it when they're done...

I think the 7mms are starting to get just a bit more popular. I've always loved 7mms, and while there has been a wide variety of excellent hunting bullets available, the selection of match bullets has been very small by comparison. Maybe the 7mm will increase in popularity enough to cause...

I've had very good luck with Varget and CCI BR-2s. Second choice would be RL-15 and 210Ms.

All things being equal, yes. However, things are never equal and there are several other things that can affect velocity. So in a way velocity can be an indication of pressure, but yet some barrels are capable of producing extraordinary velocities at safe pressures, so you have to keep other...
