HARD TO PRIME
I primed these cases with a bench mounted priming machine, even with this machine it was a hell of a workout. I used Remington primers don't know if there is better brand easier to load that is. Great value for the money though. Some body said they were looking for long range cases the only ones i saw for sale were 454.00 a thousand and they were not matching lots.

Excellent price for the quality of the IMI brass
I have now bought two separate 1,000 case lots of this brass from Wideners. It is reasonably priced for the quality. I am partial to IMI ammo loaded with SMKs so feel the brass will likely match the quality of IMI's ammo.
I weighed and measured ten cases pulled haphazardly from a box of 1,000. AVG weigh 180.32, ES 2.4. OAL AVG 2.00935, ES 0.0065. That is a tad heavier than LC brass, although in testing I found the IMI cases to have slightly more water capacity than LC cases. Please make your own measurements and draw you own conclusions. I consider these IMI cases a good proxy for LC brass which I have been unable to find new. Not Lapua, but not Lapua price either :-)
If you do not have or cannot buy any WW LR primers I'd suggest you skip this IMI brass. The primer pockets are quite tight and I deformed several Federal, CCI and UG primers trying to seat them. WW LRPs are a tad smaller by my measurement and go in OK. S&B primers might work too, but I haven't tried them. The primer pockets take a 0.208 pin gauge easily, 0.209 needs a push so let's say 0.2085 would be a press fit? The tight fit was quite frustrating, honestly, but the upside is the brass will probably last through more reloads as one can switch up to larger primers.
Being bulk packed, some case necks are a bit dinged up, but salvagable. As they come from the box the neck tension on these cases is quite tight so I'd recommend at least running them into an expander ball before loading even if you don't neck size them.
At risk of stating the obvious as I said I think the IMI cases are a good proxy for LC cases, please remember they have less volume than most commercial cases so you *will* have to adjust loads down if they were developed in commercial cases.
Overall take: Good, tough, LC-proxy brass for a reasonable price.

IMI is the best bulk brass around.
Excellent service from Wideners as usual.

Outstanding new quality cases
I was looking for new unprimed military weight cases like Lake City National Match or M118 Long Range. Unfortunately, these cases are hard to find and not new. IMI cases appeared perfect. I ordered one afternoon and received the IMI cases two days later. Excellent service. With shipping the cases were around $300.00 per 1,000. Thirty cents per case. The 1,000 cases arrived loose in one big box. Prior to reloading I neck sized the cases to insure the necks were uniform. I immediately loaded twelve rounds. In six I used CCI 200 primers and in the other six I used CCI 34 primers. For nine of the cases I used a primer pocket uniformer and reamed the flash holes. I didn’t have any primer seating problems. The three untouched cases primed easily also but I felt the primer pockets were slightly tighter. I used an RCBS Automatic Priming Tool for all twelve cases. All cases were checked with a L.E. Wilson case gauge and were within SAAMI specifications. Case length was between 2.005 and 2.012 inches unfired. The majority were around 2.010 inches. All lengths were within SAAMI specifications. I did have to chamfer the inside of the necks.
Three cases from each primer group were fired in a 308 bolt rifle and an M1A. All chambered well and extracted well. Most of the bolt gun fired cases would still fit into the Wilson case gauge. The M1A cases were a little oversized. After resizing, the M1A cases exceeded the maximum case length, any where from 2.016 to 2.022 inches. But they did fit inside the Wilson case gauge at just below maximum headspace. The bolt gun cases, after resizing, were still under the 2.015 maximum case length and won’t need trimming, unlike the M1A fired cases.
Bottom line, these are quality cases. They should be reloadable several times. The second reloading averages out to fifteen cents per case. This is fairly inexpensive compared to more softer expensive cases that get chewed up in an M1A. If you buy 1,000 cases I would expect you to be a serious reloader. As such, you probably have a primer pocket uniformer, case gauges, flash hole reamer, case trimmer etc. I didn’t have to swage any primer pockets. After dry media tumbling the cases still looked brand new. The Speer reloading manual #14 uses IMI cases for some of the 308 Winchester data.

Comparison of 30 random cases to like numbers of LC cases:
IMI - Avg 179.8 grains, Extreme Spread 1.8 grains, SD 0481; LC 89 Match - 177.7, 3.1, 0.826; LC 75 - 177.9, 5.0, 1.21
Caveat: LC cases are once shot then head spaced prepped and trimmed to 2.005" case length
Review by Rufnek (Posted on 10/22/17)
Excellent brass, cases were already prepped and ready to load. Primers went in smoothly, I checked a lot of cases with a case gauge and every one was spot on. Never tried the IMI brand before and won't hesitate using this brass again.
Review by Mike (Posted on 5/22/17)
This brass exceeded my expectations. I am new to .308 and didn't want to deal with machine gun fired 7.62 brass and thought I'd give these IMI cases a try. I recommend this product.

All I ever use for long range rifles
VERY GOOD BRASS, I like it better than any other.
My hand loads out of the Rem 700 PSS,to the GA Precision high dollar bolt 700's,have consistently shot half inch and Below w/175 Sierras@ 0.15 off the max.
It's case thickness requires you to start approx 2grs off max.
Drive them to approx 2710,FGM 210, or CCI BR2's.
Will get you unreal accuracy if you do your part.
Used thousands over 20 yrs.

Best choice for self-loading match guns.
As others suggested, this is traditional military weight. Unlike .223/5.56 and .30-06, for which U.S. military and commercial brass tend to be close in weight (actually LC is slightly lighter in .223), the .308/7.62, second only to the .300 WM, has more weight and powder capacity variation among headstamps than any other. This difference grew after Winchester designed the semi-balloon head brass for the 1992 Palma match, which got down in the 150 grain range, and which they adopted for regular .308 and some other brass later. Original Lake City brass was always closer to 180 grains. However, I understand that in 2012 ATK put out a request for new military case designs to reduce cartridge weight by 10%, and I don't know the status of that undertaking. But this IMI brass is like the orininal military spec brass, but tighter in weight tolerance and with cleaner mouth trimming, as mentioned.
The first 30 cases I measured ran 179.3 to 181.2 grains, for a mean of 180.25 grains and an SD of about 0.55 grains. But I'll caution that this was grabbed off the surface of the box and was not a carefully random sample, so until I get time to weigh a few hundred, I won't be fully satisfied on either figure.
My 0.0760" (minus 0.0002" tolerance) pin gauge was the fattest to pass through the IMI flash hole, where the new Starline brass I was evaluating recently passes a 0.0800" gauge, more like other commercial brass. So the IMI has about an 11% smaller gas vent aperture. But this is not as small as the 0.069" flash holes in some European brass, so I don't anticipate special treatment. If you are using one of the spherical powders that needs a magnum primer to ignite it consistently, this may actually help the gas pay out a little more gradually into the case and influencing pressure variation slightly less. But if you see ingition issues (high MV SD on the chronograph is a clue if you don't own a Pressure Trace or a standard pressure barrel), figure to use a 0.080" or 0.081" flash hole reamer on a few to see if that helps.
The primer pockets on all IMI brass can be tight. I had some of their .45 Auto MATCH at one point that I had to run through my Dillon primer pocket swager like crimped brass before my Dillon Square Deal could seat primers in it properly. The SAAMI spec for large primer pocket diameter is 0.2085"-0.2100". My 0.2090" pin gauge will not fit either the IMI or Starline pockets, but the 0.2080" gauge drops to the bottom of the Starline and wiggles slightly, while it will only go about half way into an IMI primer pocket. I figure IMI may be targeting 5.28 mm, which is 2.079", and is slightly below U.S. standard size range. So don't expect the tight TulAmmo or Wolf primers to squeeze into these willingly. You'll want to swage or open the pockets with a #4 reamer (0.209") for those. The Federal primers will squeeze in, and folks using maximum pressures will be happy to have a little extra tightness for primer pocket diameter to grow a little over several load cycles.
Like military and commercial brass here, the neck wall total indicated runout is typically somewhere around 0.002"-0.003", with a some smaller and some larger. For bolt gun match loads, you'll either want to sort the best ones out or outside-turn the necks uniform. But in self-loaders I don't think you benefit much from going to that trouble.
So, if you still shoot Palma or other 1000 yard disciplines with a .308, you may want lighter brass to be able to squeeze an extra couple of grains of powder in and gain a few feet per second. But for M1A, .308 Garand, and AR10 type rifles, the IMI brass is the thing to have at the moment. If you shoot Benchrest, you probably want Lapua or Norma brass for its tight wall runout. But for rugged brass that doesn't cost an arm and a leg, especially for self-loaders, this IMI Match brass is the ticket. Impossible to beat at this price. I gave it 5 stars for being the best match to this purpose.
Review by Unclenick (Posted on 2/14/17)
Purchased brass looking for something between machine gun fired LC Brass and the expensive Lapua Brass for my bolt guns. This brass is extremely nice, very uniform and loads right out of the box with minimal prep. The brass is heavy like LC brass so when working loads start low and work up watching for pressure. Some data tables will give loads using lighter Winchester brass and you will not get to the max loads listed in those manuals. Other than that, this brass is high quality, match grade material. Might buy another 1000 :)
Review by Robert (Posted on 2/1/17)
Bright consistent brass.
Found brass to be uniform and case mouths chamfered ready for loading. A few cases required a pass over the sizing die expander ball to round up the mouth. Primer pockets are tighter than other brands of brass, but should extend loading life of the cases. I use Federal 210M for bolt gun loads, and Remington 9-1/2 primers for M1A loads. Both required 'firm pressure' on the priming tool handle to seat the primers below the bottom of the case. Overall, these cases can be put into service with minimal prep work; more so than all other brands except maybe the most expensive. Test loads with match grade 168 gr bullets resulted in sub MOA groups at 100 yds. Next test will be 175 gr loads at 600 yds. Expectations are that this brass will not detract from accuracy performance at that range based on 100 yard test firings.

High quality, great value!
These are beautiful cases, nice polish, nice finish. Some out of round mouths due to bulk shipping to be expected, they all go thru the process anyway. Overall great value! Will buy again!
