Favorite mass produced bullet?

107 Sierra a real shooter

Almost everyone in my group shoots it. I'm the maligned Hybrid shooter, but I know they can hear the steel ringing even though they appear not to...
When the Berger 105 first came out Berger said the minimum twist was a 1:8 twist and after a couple of years they changed it to a 1:7 twist. I called Berger and talked to Brian Litz the Berger Bullets Ballistician and asked him about this change. He said some further testing resulted in the 105 Hybrid twist rate change and also the Berger Twist Rate Calculator was changed to reflect this. After the calculator change my stability went from the Comfortable Stability area into the top of the Marginal Stability area with the BC being compromised by 2% and it showed a new minimum twist rate of 1:7.75. Brian said not to worry that I should not have a problem with the twist rate of 1:8 and that appears to be what I have found. I am not sure what the elevation is where you shoot but at 1000 feet elevation, 80 degrees and bullet speed of 2800 FPS a twist rate of 1:8 is optimized, I shoot at sea level. With all the variables that apply you really need to use the Berger Twist Rate Calculator to check the twist rate needed. The published Twist Rate on the bullet box or advertisements cover a generic situation and not necessarily yours.

Here is the link to the Berger Twist Rate Caculator.

I also looked at a newer box of Sierra 107 HPBT MatchKings and they also say 1:7 twist only. I believe that was also a change from 1:8 a few years ago.

Good observations. Guessing many do not realize how altitude affects ballistics, even though they might plug in the variable
 
Good braggin' rights for distance! No so much for fragmentation. Where did you hit her?...and don't say "over on the west forty.";)

Thanks Stan for the pic.
The bullet recovered came out of her upper back but good penetration considered the distance I didn't shoot it one of the gentleman that I set him up on long distance shooting did this an I have the video of his success I was impressed with the bullet performance even it is not logical to do that kind of shooting on game with such a small caliber not much on bragging just a guy that likes to shoot long range.

Stan, I didn't mean to suggest bragging-just that is quite impressive a shot. Thanks
 
For a slow twist and short freebore

60g sierra Hp-super accurate

Speer 70g TNT- you will just have to experience this bullet's accuracy to believe it

Ferg, what distance are you shooting? Are your loads all the same except the bullets? Does each bullet have the same SD?
Ben

We shoot steel, 500 to 1000 and groundhogs in mid to late Spring into Summer. Loads differ by bullet weight, 115s are quite a bit different than 105s. I get 3075 FPS from an XC or 243win with 115s and 3125 FPS for 105s - w/30” Broughtons or Bartleins throated accordingly.

The list of bullets is based on 1000s of bullets measured/sorted by ogives and weight and then shot in carefully prepped Brass. If the want low single digit ES and SD, start with the best bullets you can find and concentrate on Brass prep. If every case isn’t the same you’ll struggle to maintain consistenty with ES and SD. Your trying to create the same explosion, pressure, vibration, compensation etc.

New Brass Prep
You can weight em now/later
File case head to datum length
Square primer pocket to proper depth
Clean up any burrs in primer pocket hole
FL resize with proper bushing
Tumble
Trim to overall length
If your gonna neck turn do it now
Chamfer case mouth
Weigh again
Tumble

Your done with Brass, now drop powder to just under your specified/known load and weigh to .02 grains, seat a quality sorted bullet. I would be shocked if the load with the prep above doesn’t hold a waterline with a good trigger puller.

When you consider price, quality, ACCURACY, availability and the fact that these bullets are almost benchrest in quality and accuracy I would give the nod to the SIERRA 87 BTHP GAMEKING.
 
i have tried them all. hornady cheap for a reason. won't waste my money. sort a couple of 100 and you will see why.

Match Kings are nice bullets they are in second place.

but my money goes to berger.
VLDs can shoot lights out. A little finicky to find the right seating depth. i usually shoot them jammed but they will jump. my experience when you get them dialed they will outshoot the hybrid but not by much
the hybrid is my go to bullet. Easy to dial in. much more forgiving on seating depth. shoot lights out.
