300 gr Sports Master Bullet in My 45 Colt

Written by Sierra Bullets Ballistic Technician Phil Mahin

My testing continues with my Henry carbine in 45 Colt and I have found out that it likes the Sierra Bullets #8830 300gr Sports Master JSP. I was hoping to catch one and show what kind of expansion it gives and it took some doing but I finally did.

The bullet to the left weighs 288.84 grains and the fragments weigh in at 11.04 grains for a total of 299.88 grains from a 300gr start. This was made with an impact velocity of 1,604fps and it went through 54 inches of water just to bounce off of the large blue barrel I had placed behind everything, just in case (and thank goodness I did). With this kind of performance, it should break bones easily and still keep going. It could easily be put to other applications where maximum penetration is required. This velocity and likely more could be better obtained from a 454 Casull and Big Horn Armory just happens to make a Model 90A .

The accuracy from this bullet is fantastic as it gave me a 0.76” center to center group size with a lighter charge (slower velocity) from my firearm. One thing I noticed when crimping, it doesn’t give in as much as our 240gr does so the crimp looks and feels different between the two.

I’ll be the one at the range with the kids sporting large smiles screaming “Shoot another one!” when a refilled liter or 2 liter bottle blows up.

Till next time, enjoy your shooting and be safe.

Editor’s Note: Due to the fact that this is a rifle, this bullet had no difficulties traveling from the case to the end of the barrel. A revolver having a gap between the cylinder and forcing cone can be hard on this and our other bullet so a velocity cap is put on both. Keep our 300gr bullet under 1,550fps and our 240gr under 1,400fps from a revolver style firearm.

FAQ: New Sierra Bullets Ownership By Clarus

As many of you have recently learned, Sierra Bullets has been acquired by the Clarus Corporation (NASDAQ: CLAR). We are excited for this opportunity to expand the great service and top quality products we offer to you moving forward.

Prior owners, BHH Management, acquired Sierra Bullets in 1969 from the founding partners and owned the company for almost 50 years. In the twilight of their careers, BHH Management set out to find new owners who could be diligent stewards for another 50 years and beyond. Clarus Corporation’s matching organizational values and intense focus on quality made this an easy decision for them.

The leadership behind Clarus Corporation have a rich heritage in the sporting market, which is what attracted them to Sierra Bullets. Their other companies such as Safariland Group, Black Diamond, and Pieps demonstrate their commitment to the outdoor industry. Many of you will be very familiar with The Safariland Group and their long history of providing innovative holsters and protective equipment to consumers, military, and LE customers around the world.

We will be happy to answer all your questions about the transition.

  1. Will Sierra Bullets be moving?

    No – Clarus has committed to keeping Sedalia, MO home for all 140 Sierra employees and their families.  Unfortunately, our dreams of moving the plant to a private tropical island were quickly squashed. =(

  2. Will I will be able to get the same great bullets I have come to love?

    Yes! There are no planned changes to the existing product line, but watch for exciting new additions in the future! Perhaps our dream of making a self-propelled gravity defying gold core titanium bullet will finally be fulfilled! =)

  3.  Are there any changes to the staff?

    Nope – you are still stuck with all of us from the President on down.

  4. Can I invest in the company that now owns Sierra Bullets?

    Yes – Clarus Corporation is traded on NASDAQ under the symbol “CLAR”. Or you can continue investing in Sierra Bullets one little green box at a time! =)

How Accurate is the 7.62×39 Russian?

Written by Ballistic Technician Gary Prisendorf

When someone mentions the 7.62×39 Russian cartridge, accurate isn’t usually a word that comes to mind.

The cartridge itself is capable of decent accuracy, the problem lies with the type of firearms usually chambered for the cartridge are not usually designed to be tack drivers.

We are all familiar with the SKS and AK rifles that are rugged and reliable, but we feel lucky when we can hold a 3 inch group at 100 yards.

Around ten years ago, I bought a CZ527M chambered in 7.62×39, just to see how accurate the little round can be.

I played with it some and the little carbine usually averaged around 1.5” groups at 100 yards.

A couple of weeks ago I decided to actually attempt to tune a load for my little CZ, and see what it was capable of.

I ended up settling on a load using a Sierra 125 grain Pro-Hunter #2305 and 24.5 grains of Accurate 1680.*

This past weekend I shot three groups at 100 yards, all were 5 shot groups using sandbags for a rest. The results are as follows:

Group #1= .990”

Group#2= .829”

Group#3= 1.083”

The three group average was .967”, not too bad for a factory carbine.

*While this load was safe in this rifle, it may not be safe in all firearms.

How Much Difference Does Ballistic Coefficient Make?

Written by Sierra Bullets Ballistic Technician Paul Box

Judging by the calls I’ve had through the years, I think some shooters might be placing too much importance on ballistic coefficient. The best example of this comes from a call I had one day. This shooter called wanting the ballistic coefficient (BC) of one of our bullets. After I told him he seemed a little disappointed, so I ask him what his application was. Long range target, deer hunting in the woods? Talk to me.

As it turned out, he hunted deer in open timber. Very rarely shot beyond 100 yds. I pointed out to him that under 200 yds. B.C. has little impact. Let’s compare a couple of bullets.

Let’s look at the trajectory of a couple of bullets and see how they compare. The .30 caliber 180 gr. round nose #2170 and the 180 gr. Spitzer boat tail #2160. The round nose has a B.C. of .240, the SBT is .501. Starting both bullets out of the muzzle at 2700 FPS and zeroed at 100 yards, at 200 yards the #2170 RN impacts 4.46” low and the #2160 SBT impacts 3.88” low.  A difference of only .58” in spite of a huge difference in B.C. If we compare out at 500 yds., then we have a huge difference of 14.27” between these two bullets.

In a hunting situation, under 200 yds, having a difference of only .58” isn’t going to make or break us. But elk hunting in wide open spaces it could mean everything.

The next time you’re choosing a bullet, give some thought about the distances you will be shooting. Sometimes B.C. isn’t everything.  If you have any questions, please give the Sierra Bullets technicians a call at 800-233-8799.

The Changing Times

Written by Ballistic Technician Duane Siercks

We all certainly remember how in the very recent past certain types of ammunition have been difficult to find. At times, it seemed almost impossible to get your hands on 22LR ammo. And you could forget about the 22 WMR. That was virtually impossible. But in the last few months we have begun to see the 22LR supplies being more visible. I had one of the fellow employees remark that he was able to walk into Wal-Mart and buy all the 22 ammo he wanted. I did get an e-mail notice from a major distributor concerning the 22 WMR ammo now being available in good quantities. They were also offering special prices on certain offerings as well.

We have also seen the availability on firearms becoming more steady. Prices have also backed up a little bit. For the most part, if there is a purchase you have been waiting to make, now would be a good time to start really shopping on prices. It is more of a “buyers” market at this time.

With hunting seasons rapidly approaching, getting that new rifle set up and fine tuned is a great idea. It would be an great time to get that young hunter into their first rifle or shotgun. Give them plenty of time to get familiar and comfortable to insure that you have a ready hunting buddy for a long, long time. Maybe it could be a new .22 rifle to hunt small game. Many of my best memories were small game hunts that were very rewarding. Especially with my wife and daughters.

Reloading components for the most part are in better supply. You will still find a few items missing from the shelves, but those grow fewer and fewer by the week. I know there was a major stocking spree in the last several years as people wanted to make sure they had their needs covered. While inventories are flush, now would be a good time to practice. While you can use some of the older stock of supplies and refresh it with new. You could also work on and possibly improve your loads.

Even though this seems to be a slower time in the shooting industry, this makes it all the better for the shooter. You can now enjoy your sport with less worry about supply. Go out and enjoy. Include the family. Teach them the joy of the shooting sports. Help them learn to be safe and responsible and have fun.
