Hope I'm in the right place guys, if not sorry for my bad.. Opinions on PRVI 175 FMJBT for a Rem 700 milspec 5R .308, barrel break in and just kickin around?? P.S out to 500 yds and maybe then some.....
 
Re: Ammo question

175 seems to be the right weight for mine (626 being my longest so far... a 'yote with a witness... but no pics, so maybe it didn't happen?).

I use the Black Hills BTHP Match

Burning barrel life with crap ammo doesn't do anything but make noise.

If that's what you are after drive on.

I would suggest you get some quality ammo and break the barrel in by sending it at some targets. (P.S. do a search on barrel break in).

I ran exactly 20 rounds of Prvi 175 "match" through my AI just to see. It sucked. No better way to put it. It did good to group 1.25" at 100 yards.
 
Re: Ammo question

I took a 50 hour sniper course in October and used 168 Prvi match ammo. It worked very well in my Remington 700. I had setback the barrell so the bullet was close to the lands and at 100 yards shot 3/8" groups. We shot steel out to 1400 yards with a little less than a full value wind. The 175 grain would have been better in that wind. That's my experience.

Yeah, what he said!! All the 168's I've tried to shoot past about 800 yds from a bolt gun would keyhole because of the lost velocity. When shooting paper, you can see where they are tumbling through the target. I've shot the 168's from a m1a however, and they worked a little better. For most applications from a bolt gun in .308, you are usually better off using heavier bullets (175 or heavier).
All of my shooting was done at sea level up to 8000 ft elevation. If you are in higher elevations, I would still think the bullet would run out of gas at 1400 yds. Educate me on this one please!!

Well, it can be done either: a) in a vacuum; or b) with a MV of around 3600fps!! Take your pick!!

To the OP, the 175gr load from PRVI is decent enough for practice ammo just to get some range time, but it isn't going to be the most accurate ammo you can buy by a long shot (but then again...you aren't paying the price for "match" ammo with the PRVI). I would expect 1.5MOA or so, all things being equal, with the 175gr PRVI load.

How in the hell would you get 3600 fps with 168's out of a 308 Win without blowing the bbl or the chamber? Would think the pressure would blow the gun up!! Holy shit!! Thats nuts IMHO...

Easy, tiger. I am not...nor is anyone else...getting 3600fps out of a .308...that was the point of my post!

Find a vacuum to shoot in or some other way to defy physics/gravity or find a way to push the bullet to around 3600fps which is what it takes to keep a 168gr SMK supersonic to 1400yds.
 
Re: Ammo question

No offense intended...I initially read your post too fast and started typing!! Just wanted to make sure I wasn't losing my mind or something. We are on the same page.

Re: Ammo question

No worries, Chad. I didn't take offense at all. I didn't figure anyone would take me seriously on the 3600fps thing.

As for losing your mind...wouldn't worry about that. Most of us, me included, lost it a loooong time ago!

Re: Ammo question

The PRVI 175's are FMJ and I agree with what has been posted above, they are mediocre at best. However, the PRVI 168's are HPBT and are definitely better, still not great but are ok for close in work if your expectations aren't too high.
 
Re: Ammo question

Obviously the 168s as is any 308 round at their outer limit at 1400 yards. The course was in Phoenix at about 1200 feet. The temperature was about 80 and it took 74 minutes of elevation to get there. In the spotting scope you could watch the con trail on the bullet and the flight time was about 2.5 seconds. They would literally dive into the target with that much elevation on them. At that distance the speed was under 500 fps and would not be the best choice for a serious encounter, but they did function. Others were using Black Hills and Federal Match with similar results. Obviously, we were in a zone that should require at least a 300 win mag for decent results.

I'm throwing the BS flag on this one!! 168's lose supersonic wayyyy before 1400 yds out of a bolt gun, especially at only 1200 feet elevation. What you are saying doesn't add up to what most of us have personally experienced using 168's from a 308 Win. Thats why most of us use the heavier stuff. You MIGHT hit something at 1400 using a 168 from a 308 Win, but it sure as hell won't be consistent, much less accurate. Guarantee that bullet is tumbling in the air. There isn't enough gas behind that pill at that distance. Ain't happening, my friend.

Re: Ammo question

Its not the indirect fire with 168's that I am calling "shenanigans" on. You didn't say how big the steel was, or what your hit ratio was. So I have no need to call BS on that. You could have been slamming the side of an old M60 tank at that range and calling it a hit. I can guarantee you that the 168's were not anywhere near stable at that range.

It's the 3/8" groups @ 100 yards I am calling BS on. If you said 3/4" groups I would have believed you. If you are talking about one or two 3/8" two shot groups I might even believe that.

Consistent 3/8", five shot groups from 168gr Prvi I would have to see to believe. If it were true I would be more than happy to have our department to start buying Prvi over Federal Gold Metal Match for practice. Hell, I would even start shooting Prvi at matches where I didn't want to handload.

I have gone out on the same day, with the same rifle and shot 1/4" five shot groups with Hornady Custom, then shotgun pattered Prvi. It really is only good for minute of steel.
