What bullet weight is, in your opinion, the best for general purpose defense out of a 20" 1:9 twist bbl.? What are the advantages of a 62 grn bullet opposed to a 55 grn? Thanks!
1x9 - good all around twist ratio. Best suited for 52-69 gr, but either end of the envelope will be questionable.
Q. What ammunition does Troy recommend for self-defense, storage, plinking, training and match use?
Self-defense ammo: Self-defense/home-defense ammo should be selected to match your individual situation. For example, you might compromise penetration a bit if you live in an apartment and have little control over what happens on the other side of an interior wall.
Special needs aside, I would recommend using the load that will give you the best terminal ballistics available out of your rifle. You probably don't need thousands of rounds of this ammo, but at least 80-90 rounds (four 20-round mags or three 30-round mags full) is a good idea. You must consider the barrel length and twist rate of your "go-to" rifle as well.
As I have 1:7 barrels available and have access to Black Hill's "Mk262 Mod1" loads (77gr Nosler or Sierra), that is my first choice. I can also handload these bullets for practice, allowing me to have some training with this load at a lower cost. An excellent alternative would be either Mk262 Mod0 or the nearly identical Hornady TAP load, both featuring Hornady's 75gr OTM bullet.
For 1:9-twist rifles that have at least 14.5" of barrel, the best performing loads use either Hornady's 68gr OTM or Sierra's 69gr OTM bullet. Loads are available from Hornady and Federal respectively, as well as from Black Hills. I prefer the superior terminal ballistics of the Hornady bullet over the slightly better accuracy that's often found in the Sierra bullet.
For an older 1:12-twist rifle, M193-class ammo is the way to go. And if you can't afford or obtain one of the more expensive loads above, M193 will serve you well in any barrel twist.
Plinking ammo: Plinking is supposed to be fun, and give you time behind the trigger. As such, any ammo that works reliably in my rifles is fine for plinking, and the cheaper, the better. My rifles don't have a problem with Wolf ammo, so I use that sometimes, but I often use my own reloads or inexpensive surplus ammo.
Training ammo: Real training is ideally done with your carry ammo, but for most folks, myself included, this would be prohibitively expensive. Thus, I generally use M193-class ammo for training, since it at least is a hot load that gives realistic recoil and muzzle blast. I try to use surplus ammo with Berdan-primed brass on ranges where I won't be able to retrieve the cases. It's a reloader thing...
Storage ammo: By definition, this is duty ammo that you're buying now, in the event that it won't be available in the future, for whatever reason. This ammo should be top-quality ammo (and if it isn't, replace it with better ammo as you can), and it should be ammo that gives good terminal ballistic performance. While I have a supply of my preferred "heavy match" duty ammo, I also have M193 and M855 ammo stored. You should always test your storage ammo in your rifles first, then store them in ammo cans and LEAVE THEM SHUT. Keep the cans cool, and it will out-last you.
Match ammo: I load my own, primarily using Hornady 68 and 75gr bullets, since I also use these for my training ammo. Match loads are typically only loaded to 90-95% of max pressures, as maximum loads tend to suffer in the accuracy department. If I didn't load my own ammo, I would shoot Black Hills loads.
Q. What ammunition does Derek F. recommend for self-defense, storage, plinking, training and match use?
Self-defense ammo: It all depends on the rifle I pick up. With a 1/7 twist rifle, I’m a fan of the Nosler 77gr., which I handload myself as close to NATO pressures as possible. With a 1/9 twist rifle, the 68gr Hornady gets my nod, which I also handload. With either of these rounds, I expect to be able to defend myself out to a distance of approximately 200 yards and no farther. Anything beyond that distance and I’d rather retreat/evade. I have no idea what kind of weapon I will be facing, and I’d rather not take the chance of engaging a scoped rifle with iron sights at long range. I try to cycle through this ammo as quickly as possible, so long term storage is not a concern for me with my defensive ammo.
Plinking ammo: I’ll shoot just about anything…as long as it is relatively accurate, goes boom each time and cycles reliably. I’ll use this ammo for hitting reactive targets out to 300yds such as fruits, steel plates and propane tanks. Basically, if it goes “clang†or explodes, I consider it plinking.
Training ammo: I alternate between Q3131A and XM193. I don’t really have a preference as far as accuracy/reliability are concerned, however Q3131A is easy to find locally, thus it is the slight favorite. For training ammo, I want the utmost in reliability and accuracy while still keeping M193 spec. This is probably the most common ammo that I will find in a SHTF situation, so it is what I train to use.
Storage ammo: When it comes to storage, I'm more packrat than human. I currently have in
excess of 20k rounds of Q3131A and XM193 stored on stripper clips in bandoliers in both .30 cal and .50 cal ammo cans. Each ammo can contains 2 stripper clip spoons for ease of loading along with a pack or 2 of desiccant. I rarely drop below the 10k mark, and when I do I make sure to pick up another case or two. My BoB consists of 1000 rounds of Q3131A in 20 round mags and on strippers."
Match ammo: I don’t do much match shooting, but when it comes to absolute accuracy, I usually go with the Sierra 77gr MatchKing in the Federal Gold Medal Match loading. With this round, I am able to get sub-MOA groups out to 300yds using a 16†M4 barrel.
Q. What ammunition does Tatjana recommend for self-defense, storage, plinking, training and match use?
Self Defense: My self-defense ammo selection is driven by several requirements.
1. My rifle (16" Bushmaster 1:9) is my primary self-defense weapon. My pistol is used to fight my way to my rifle.
2. I doubt I will ever be in a situation where I have to engage anything beyond 200 meters. Even 200 meters is hard to see happening.
3. Because terminal performance is critical to me a short neck and severe fragmentation is important in gel testing.
4. I need a round that will be available in enough bulk to practice with. Cheap would be nice, but I'm not all that concerned with price for this stuff since I only really need around 500-1000 rounds for long term use. My self-defense round is used to augment my M193 stores and for home defense. 5 or 6 twenty round magazines are near the rifle at any time.
Given my requirements above. For self-defense I have moved from the 69 grain Sierra Match King to the 77 grain Nosler NATO loading from Black Hills. These rounds meet all my needs particularly in terminal performance. They are expensive but I think them worth it. I have two rifles in which the 77 grain Nosler works well out to at least 150 meters, both of which, ironically, are 1:9. I intend to switch my home defense weapon to a 1:7 barrel as soon as I can get my hands on one. That will make me even more sure of my 77 grain loadings.
Plinking ammo: I usually use plinking as an excuse to burn off old M193 stores. Q3131a and XM193 figure prominently in my plinking use. I don't shoot Wolf.
Training ammo: I don't distinguish much between plinking and training. Accordingly, I tend to use NATO loadings for training. Usually this is a mix of M193 and Nosler 77 grain. "Train like you fight," is an important concept for me so I take it to heart and use the ammo I am mostly likely to have to fight with when I go to the range or when I'm just plinking. M193's cost (or lack thereof) makes this work well.
Storage ammo: My circumstances are somewhat unique so I store more than 5000 rounds of XM193 or Q3131a (though I prefer XM193) at any given time. As soon as I get close to coming under the 5000 mark (rare) I buy more M193. I cycle out the old ammo with the new so at any given time my storage ammo is as recent as it can be. One exception is the emergency "bug out" pack I keep of 1000 rounds. I don't ever break into that unless I have another prepared pack to replace it with before I open the first.
I don't store Nosler 77 grain since it pretty much sits out ready to go all the time. My M193 stores are on strippers, in 7 pocket bandoleers stacked in ammo cans. I use the dry ice method to purge air from my cans and then use a moisture absorbing pack to finish them up before I seal them.
Match ammo: I am a big fan of Swiss GP90 for military or service rifle match ammo. It has the disadvantage of being a horrible terminal performer though so I don't keep much of it around. For more serious match ammo I am partial to 69 grain Sierra Match King and 77 grain Sierra Match King.
M855 62gr. ammo was designed to penetrate. Good for shooting through light cover, but this is not what you want in a personal defense round. IMO, 62gr. offers no advantages and only dissadvantages for civilian defensive use.What are the advantages of a 62 grn bullet opposed to a 55 grn? Thanks!
Note I said maximum distance. Think of the longest possible space you have in your house to shoot across. For me it is from the end of my hallway to the far end of my living room. Probably about 15-20 yards. More likely the bad guy will be closer than that.Any home defense is more likely to be @ 20' or less, not 20-30 yds.
