    I listened as a hot shot guy from up north said he had the most accurate rifle he had ever seen and how no one could come close to his beloved lazzeroni custom made gun . I asked if he'd be interested in shooting one day and he took me up on it . I had to meet him and one of his friends at a store , he knew of a place we could shoot out to 500 yrds . It was a nice property , long story short , @ 100 yrds he had a tighter group than I did but that's where it ended at 200 , 300, 4&500 yrds. I got him ! I don't talk much . We did 3 shot groups each time . I felt good going home . I know most don't like the RUM's because they think they are overbore etc. but they can hit and are accurate . That was the first time I ever took my Rifle out to shoot against anyone and I haven't seen many custom rifles in my day . If you have a 7RUM it's a good Rifle . That custom Rifle Is Beautiful I had never seen anything like it and I was afraid when he handed it to me , it was alot lighter than mine with a large scope on it .

    My buddy's factory 700 CDL 7RUM was lucky to shoot a 2.5" group @ 100 yards. Cold bore it was dead-on, but shots 2 and 3 were always a crap-shoot. It has since been rebarreled to a custom 7mm STW.

    And you best believe that when I get behind the wheel and try to group one, and it won't group...It's the gun, not me.

    He bought the gun used from the original owner (who is a friend of both he and I), and the gun had had less than 20 rounds through it. He put 20 more down it, and called it quits.

    Not saying they're all that way. But his was junk. His was a "Minute Of Pie Plate" gun, which is sadly what most hunters in Alabama are ok with, because most shots take place less than 150 yards down here (not for me, of course, I strategically set myself up for longer shots). And if MY guns won't put 3 touching, then I won't take it in the woods till I get it tweaked where it will.

    I had a "minute of pie plate"7rum also.... But the last two 7rum's I've had will deliver 1/2 moa with decent loads with ease. My brother also has a sendero 7rum that is a fine weapon. I'll take a 75% chance of a caliber doing well in a rem any day; that's better than their rifles in general from what I've seen.

    I know they use alot of powder in each shot so I make it a point to really clean my barrel really well, sweets 7.62 is what I use . I know that with production Rifles alot of them will shoot good but after a while some Won't shoot so good but some Will Shoot Very Well . I must have been very lucky I guess it has a Beautiful Wood stock too . I don't over use it but it has no problem with long shots at all .

    I've been thinking about the 300 RUM a bit too I see they use it in the Military so it must be pretty good too . :)

    I've got both the 7rum and 300rum.. the 7 seems to like being a screamer (140 grains or so) while the 300 is a mid to heavy pill rifle (180-225grain).

    They don't use the .300 RUM in the military...They use the .300 WinMag. Different caliber completely.

    The .300 WinMag is based off the .300 H&H case, which is smaller and belted. The RUM calibers are based on the .404 Jeffery which is a larger, non-belted case.

    I consider the 7mm RUM to be VERY OVERBORED but like the accuracy it can produce if the right bullet is used.

    The mistake most people make is to try light bullets. The big RUM needs 160s to 180 grain bullets
    to reach it true potential with all of that powder.

    With all of that velocity and twist rate they like bullets with long bearing surfaces (Bodies).

    Just my opinion based on my experience with the 7mm RUM

    I'm just kind of curious how you deem a rifle a complete POS in only 20 shots? That's not enough rounds downrange to try different loads or work up a load. Not really enough rounds to properly evaluate the firearm itself for proper fit, function, etc. Maybe working up a load, bedding the action, etc. would have reaped different results. Maybe you did all that... just curious.

    Exactly! Just like the STW really flourishes with the 180 Bergers, and if you have the right twist, the 195 Matrix bullets.

    When the best group I got was 2.5" and majority were 4-5"....That's how.

    It was a sporter barreled 7RUM... Enough said. A huge overbore caliber, in a whippy skinny pencil barrel is never a good combo.

    Plus, when I had a spare heavy 26" 7mm STW barrel waitin in the wings, and he knew he could buy it from me, he decided to build a custom, and go that route.

    While it might not be optimal, I have seen plenty of overbore calibers shoot great with the standard sporter barrels, so I don't think you can say it's never a good combo. In fact, it can be a great combo if you have to tote it around the mountains deer or elk hunting.

    An extra 1½ lbs of barrel (sporter vs Sendero/varmint contour) ain't gonna break your back. I've walked for miles toting my Senderos and Accumarks through the woods. All weighing well over 10 lbs with scopes and ammo. Just my thoughts on it.

    I hear ya...but the woods of Alabama are a little different than the woods of Colorado :D Either way, my main point is that sporter barrels can shoot just fine in overbored calibers. 1/2 MOA is 1/2 MOA and 1/4 MOA is 1/4 MOA, regardless of what contour your barrel is.

    Well, my family is from north Alabama in the southern end of hte Appalachians. So we do have mountains up there. LOL

    But I rarely hunt up there, mostly in south Alabama.

    And as for shootability...I agree. If it shoots good, it shoots good. But a sporter contour barrel and a huge magnum cartridge is not an ideal combo, and more often than not, it will less accurate than a heavier contour barrel in the same caliber.
