Ladedata Barnes Triple-Shock 168gr i 30-06

[Osse]

Skal prøve Barnes Triple-shock i år, skal lade for 30-06 og 308W, men har ingen ladedata eller hastigheter. Noen som har ladedata? Kan også bruke data for 165gr X som referanse.
Noen som kjenner BC for denne kula?

Hej Osse,

Välkommen till forumet!

Triple-X är en spännade kula, själv har jag laddat Barnes XFB, XBT och XLC mest i .270W och .280Rem.

<i>Triple Shock X Bullets - Questions and Answers.

1. What load data do I use for the Triple Shock X Bullet?

We recommend that you use the minimum X-Bullet load data to start. To compensate for the reduced pressures associated with the Triple Shock, you may have to work up 1 to 2 additional grains above listed loads to achieve equal pressures. Pressures can jump dramatically; therefore we recommend that you work up in 1/2 gr. increments until you are no more than 1 to 2 grains above the listed max load or until signs of excessive pressure are evident, whichever comes first. You should watch for excessive case head expansion, sticky bolt lift, flattened primers or shiny spots on the base of the case. If you have case head expansion of more than .0005" with a once-fired case, this is a sure sign of excessive pressure. You will have to measure your case head with a Blade Micrometer just in front of the extractor groove, or you can use a regular micrometer and measure the belt on belted cases, before and after shooting. When any of these signs appear, back down one full grain and you will have a max load for your gun.
If you do not feel comfortable working up a load, or don't have the proper equipment, then we suggest following the recommended X-Bullet load data. For the 168gr .308 cal Triple Shock X Bullet, use the 165gr X-Bullet data.


2. Since the Triple Shock and the XLC coated bullets are similar and both reduce pressures within the bore, can I use the XLC load data with Triple Shocks?

No! While the Triple Shock and XLC both reduce pressures, they are very different and each bullet has it's own strengths. Reloading using the XLC load data will cause excessive pressures in some cases.


3. How much velocity is gained using the Triple Shock X Bullets over the X-Bullets?

Between 50 and 150 fps can be gained over the X-Bullet when a proper load is worked up.


4. Will I see reduced fouling with the Triple Shock Bullets vs. the X-Bullet?

Yes. Due to the reduced surface area touching the bore, you will see reduced fouling.


5. How do the Triple Shock X Bullets compare to the X-Bullet and XLC Bullets?

The Triple Shock and XLC Bullets are designed around the time-tested and proven X-Bullet. You will find the terminal ballistics to be the same with all three.


6. How is the accuracy with the Triple Shock?

In testing we have found the Triple Shock X Bullet to be very accurate.
To view another test on the accuracy of the new Triple Shock- check out the July issue of Shooting Times and Rick Jamison's article on " New Loads for an Old Favorite - The .270 Winchester.


7. Where do I seat the Triple Shock X Bullet?

As with the X and XLC Bullet, we recommend seating the Triple Shock .050" off the lands {rifling} of your rifle. This length can be determined by using a "Stoney Point Gauge" or other methods. You do not have to seat the bullet at or on one of the annular rings.

Takk Mecke og 6,506

Har funnet en post på accuratereloading med data fra Barnes manual #3.
Der oppgis ca 2900fps som max for Barnes X 165gr. Og ut fra det jeg leser av Meckes post kan jeg regne ca 2950-3050 fps som maks for 168gr triple-shock.
Høres dette ut som en sikker ladning?

Kommer til å bruke Norma 204 og CCI 200 knall.

Kom gjerne med betraktninger!
