Factory Ammo

Post by lowndsie »

Who uses factory ammo and what do u find is the most accurate brand??

Ive used PMC 55gr factories in my 223 for awhile but they shot into 2moa so I just blasted them off for the brass.

I also had mixed results with winchester 64gr factories for the 223.

It varies a lot, but one ammo that is poor in one firearm can be gold in another.

However the most consistently well performing factory ammo i have seen would have to be Remington Accutip in various calibres. It can put down some respectable groups.

But like i said it will vary a lot as to which is best from rifle to rifle.

G"day All

Shane- A mate of mine used the remington in 204 cal and it was junk ,he took 100 rounds or so back and exchanged them for hornady which were brilliant.(rifle was a kimber).
I have used the winchester factory 25/06( i think its xp ammo, silver box for varmints ) and it was very accurate , i purchased 160 rounds and shot them off and then reloaded the brass, their on their fourth time round now and no sign of having to throw them yet.
I Think its a matter of you get for what you pay for as the expensive premium ammo is usually better in most rifles , same goes for rimfire(but usually more ammo sensitive).
Regards
Damien Webb.

Damien,
It's funny isn't it that the rem 204 ammo has hornady vmax projectiles loaded in it, yet they dont shoot as good as the hornady ammo in your mates rifle even though they are the same projectile.

The reason for this is the muzzle velocity, which effects barrel vibration. That is the main difference between the accuracy of any ammo, it's whatever velocity makes the barrel vibrate less.

BTW hornady make those vmaxes for remington but put a gold tip in them instead if a red one just to make remington feel special.
cheers,
Shane

Shane you might know the asnwer to this.....

Why wont my ruger vt shoot soft point pills??? The 50gr noslers BTs go into .5 moa or less!!!! The barel is a 1-9 twist so I the thought the pills might be too light but yet the 50gr and even 40gr Vmax's went into less than an inch. I tried several different brands all seating just in from the lans but they all shot over 1.5moa......Doesnt make any sense to me. I mean I've heard of picky rifles but mines just a flat out snob....

Normally I wouldnt worry because the BTs shoot so well, but I need it for a backup rifle for my roo shooting business and my wallet isnt feeling too good about using premium pills for that.

PS. I also tried 64gr power point hand loads and they were were on par with the group size of all the other sp pills....

Lowndsie,
The weight of a projectile has a ball park effect on the accuracy from a given twist rate but the thing that it is mainly governed on is the length of the projectile.

ie. the longer the jacket of a projectile the faster the twist needed to stabilize the projectile.

The 50gn BT's you run will be slightly longer than sp's so they have an advantage that way. But they also have a different balance point which will make a lot of difference also.

The 1:9" twist in your ruger is idealy suited to longer jackets which are usually around the 69gn mark. By using the 50gn's they are being over stabilized which will hinder accuracy a little but thats much better than being under stabilized which is detrimental to accuracy.

Hope this makes sense.
cheers,
Shane

Yeah thanx shane, it makes sense. So basically its more to do with the bearing surface than the actual weight of the pill. I'll have to get some 69gr pills and see how they go. Surprised the 64gr winny pp's didnt shoot a bit better though. Really if I can get any load into and inch then it's fine for what I need.

The 64gn win's are a farly stumpy projectile so they are similar to the standard 50-55gn sp.
