Hey Guys... I just picked up some 175 grain Bergers for my .300 Win Mag. Where did you find your reloading data??

Once again thanks..

 

Jason

 

ps...

Casey mentioned that you could put multiple in the magazine because they are so long... has that been shown to be the truth?

Jason,

they are supposed to shoot the best when seated to touch the lands. If you make a dummy round so, you will see if it fits in the magazine (the 130s fit in my 6.5WSM seated to the lands). With the 175 grainers, I'd use 180 grain data and work up as usual from starting loads to max for your rifle.

Is there a best way to seat it against the lands...

did you do this?

Bullet Seating Depth

Bullet seating depth has a great impact on rifle accuracy. The bullet seating depth for each individual rifle and bullet varies and should be set accorgingly.

 

Step 1. Insert a bullet into the neck of a unprimed resized case. Do not fully seat the bullet but seat it deep enough that it is gripped fully by the cartridge neck.

 

Step 2. Using a black magic marker or dykem steel layout blue, color the entire bullet.

 

Step 3. Insert the case and bullet into the chamber of the firearm and gently start to close the action. Stop as soon as you feel resistance.

 

Step 4. Remove the cartridge from the chamber, now look at the bullet, it should have well defined marks where the bullet contacted the rifling in the barrel.

 

Step 5. Continue seating the bullet deeper and chambering the cartridge until you only feel a slight amount of resistance when the bolt is closed completely. There should only be marks left on the bullet from the lands of the barrel.

 

Step 6. Now take another resized casing and with your bullet seating die set, repeat seating another bullet in the cartridge case to verify that this is your maximum cartridge length.

HELLLPPPPP!!!!! Okay as you guys know I am new to reloading... I loaded my first batch of Sierra BT last week and they shot pretty well. So I thought I just need to fine tune my loads and I would be good to go... Well, I finally got some official load data from Berger so tonight I decided to try to load a few rounds of the Bergers. Well I also got a Precision Mic from RCBS tonight from Midway and I was going to put all the pieces together to make my super load. WELL... I looks like I am going to need a bullet puller. :) The Headspacer part no big deal... That is just measuring, subtracting then adjusting the die.... NO PROBLEM... Okay So now I am trying to find the SEATING DEPTH... Okay not so good. I placed the free bore tool into my chamber and I got .080 cool... Now I figure I just need to make some dummy rounds of .070, then create the load and repeat the process for .060 and .050 depths... RIGHT... Please correct me if I am wrong.... So I setup my RCBS Press as indicated I place a shell in the hold drive the ram up(adjust the die) and then back the die up one turn. Okay... That looks good, I then test my dummy round in my SAKO... and it works fine.. NOW.. I test it on the Precision Mic. Well, that is were the problem starts. IT IS WAY OFF..... If the purpose of the Precision Mic is to be able to modify the seating depth then I am doing something way off but the Mic just about bottoms out with the Bergers. Is it because the bullets are so long and the shoulder(don't know what it is called) is so far back from the tip? My bullets would be WAY LONG....

 

Any Ideas?

 

Jason

The magic marker works OK, seating deeper until you get no land marks on the bullet.

 

I use the Stoney Point (now Hornady) OAL length guage, dummy case, and Comparator.

Might be cheaper to buy the comparator base and 30cal body separately than the whole comparator kit

I am assuming you have a dial/electronic caliper needed to use both.

It looks like I have some research to do... In most cases could i have used the Precision Mic but because of the particulars of this bullet I can't?

My reloads for my 1885 high wall are always a lot longer than the manual calls for. I let the gun determine my length, not the manuals. Most manuals give you a length acceptable to fit rounds in a magazine. The rule i was taught was, if you have at least the diameter measurement of the round worth of the bullet seated, you're okay. say you're reloading a 30-06, you want at least .308'ths worth of bullet seated into the brass, not to include the boattail. I'm sure the more experienced reloaders here will have a more solid way of doing things.

reloading is so fun and addicting! nothing like watching a buck or bull fall to a bullet you made!

I never even thought about it,but the buck I took in Oct, was the first I've taken with a reload. That is pretty cool. Thank you mister accubond :D
