Can we talk about 700s?

[jmf_tracy]

I have also considered converting the BDL to the Gen II HS precision DBM on a 700P, but I can't find too many reviews on it and the few I have found contradict each other. If, once you're done converting and have spent some time with it, you wouldn't mind doing a write up on the quality, construction, feeding/functionality of HS precision DBM system I'm sure there are a few of us that would appreciate it.

I will give it a try. the only reason that i went with the HS Precision DBM is that it is a HS Precision stock and it will readily accept without having to machine it out otherwise i would have went with something cheaper that uses AICS mags. I am sure HS Precision will function just fine.

If a 7mm kicks too hard maybe you should consider a nice 22 ?

Only with a recoil pad.

But cereal, how many rounds can you put down range with a 7mm in a day? With a .308 I can have a good day with 50-100 rounds. 7mm it's like 10-20. Too old to play "quienes mas macho". I'd much rather be a better shot with a smaller caliber than be a terrible shot but a range tough guy.

Got to shoot a 500 something or other handgun a few weeks back. Helluva gun. Probably kill with a near miss but no way in hell would I ever buy such a hand cannon.

Gotta agree with Thorax. A .308 feels like shooting a BB gun after shooting magnums. Heck, sometimes I gotta look down my barrel to make sure I didn't squib when shooting those BB guns.

We could but it's a boring subject really, Ho hum!

When I got started in precision rifles, I used an HS precision DBM setup (against everyone's advice) for the same reason (drop-in) as everyone else.
The issues I ran into were also the same as everyone else.
The mags are only available in 4 or 10 round instead of 5 and 10 round.
The mags are exorbitantly expensive.
The mags are often difficult to obtain.
Nobody else uses HS mags so if you needed to borrow a mag at a match, you are SOL.

In the end, I sold off my HS precision DBM and mags at a significant loss and went to AICS compatible setup.
This was a while ago before PTG was selling AICS compatible bottom metal for $99.
Nowadays, it's a total no-brainer.

I know know difference. So take the wind out of the equation. how is the longer barrel more accurate?...

A stiffer barrel will group better but a short barrel looses velocity. At a certain point you need a longer barrel to get more velocity. If the barrel was both long and stiff (relatively speaking) you would have trouble lifting it out of the car. So barrel length and weight is always a compromise.

Thanks, Randall. Maybe I'll hold off a bit and convert to a AICS compatible system when I upgrade stocks.

When AI has a viable option, it's virtually ALWAYS a no brainer to use them. Their rifles are a bit expensive, but for good reason. Meanwhile, do to an economy of scale that has evolved, they make great accessories for a very reasonable cost, mags, slings, mounts, etc...AI is a good value. There's no manufacturer that I'd rely more on than AI. You just don't hear about a lot of Accuracy International horror stories because they make great stuff.

Actually I was thinking 20-22", especially after reading the long distance rifle thread. Not likely that I will be taking any 1,000 yard shots. But accuracy is always nice.

You might not be taking 1,000 yard shots. But 600? Sure you will. And once you do, you'll want to try 800.... And it goes on.

But, I have to ask; how many rooms do you plan to clear with a bolt gun? Many less rooms than times you'd ever shoot the rifle long distance. So, I purpose it for that. 24" is what I shoot and will recommend.

IDK, when the zombies attack I might be forced to. When I shot the barrels out of all my other guns.

I'd like for pigs as well so humping this thing around is a bit of a consideration. I'll go check with my LGS. Maybe they have 5r vs. SPS varmint that I can fondle. And local ranges don't go past 400 yards.

The shorter one will be stiffer or more rigid. Not the longer one, assuming all other factors are the same (contour, quality, caliber, ect). But we were not debating the point of a stiff barrel vs a less stiff barrel. We were debating weather a longer barrel was more accurate than a shorter barrel. IMO I do not believe that you can say just because a barrel is longer or shorter it is more accurate or less accurate. Although I see Randall's point that a longer barrel yields more velocity therefore it minimizes shooter error by bucking the wind better.

Stiffer barrels are more precise.
Longer barrels buck the wind better so they will be more practically accurate.
Longer barrels also reduce elevation error due to miscalculation of the range to target as they shoot flatter.



Another good example of precision vs accuracy:



The 3 shots at 500yds were more accurate while the 3 shots at 600 were more precise.

Also remember this is why you hand load. To find a load that works well with your rifle. To take out the extra whip.

The way you said it there "more practically accurate" makes perfect sense. And I also mixed up the words precise and accurate in my last post so could have got confusing. Longer barrels are more practically accrate. I hear what you saying and that makes sense to me. Interesting topic. Like talking this stuff.

And also. Handloading?? What's that? I just shoot military surplus ball all in my precision rifle. Jkjk!!

...IMO I do not believe that you can say just because a barrel is longer or shorter it is more accurate or less accurate...

For any given weight, shorter (stiffer) is better. If you calculate the moment of inertia you will see the short barrel has a higher resonant frequency and a lower deflection. The shorter stiffer barrel is better up until the loss of velocity affects down range bullet performance. That's when we need to add barrel length and compromise the stiffness.
