7mmBR

[skeetlee]

Why or for what reason would anyone want a 7mmBR rifle? It sounds kinda interesting to be, but i just dont really know were it fits in. I did a search and didnt find much, thus telling me its not all that popular. I did read that a lot of the pistol shooters use it in silhouette shooting, but thats about all i could find. Whats the 7br's claim? Is it just as accurate as the other BR chamberings??? Thanks Lee

It's a heck of a pistol deer cartridge with 120 Ballistic tips at any sane distance, don't let it's size fool you any, it will get the job done...
In a good barrel with good loads it's pretty accurate......
The few I've used have been honest .750 shooters at 100 yards.

It's claim to fame lies in Silhouette pistol shooting which requires a certain amount of knock-down energy on the steel targets.

Not enough boiler room, (powder capacity) to do much for you with 7 mm bullets in a rifle. However, both the 7 and 6.5 mm versions are outstanding in handguns for silhouette. Rifle silhouette goes out to 500 yards, (meters) and handgun goes out to 200. Lots of XP style and falling block pistols use them very effectively. More recently I would say the 6.5 mm version is more popular.

I can't see where your coming from'
How does it compare to the 30br? A few thou difference in bullet diameter? I bet it would shoot just as well as the 30 BR with the proper twist and bullet, any one trying this yet? The 7br bullets would have a higher ballistic coefficient. Think we can get them to 3000 with safe pressures? I have been thinking on this one.

The 30BR is a very good short range score cartridge and will shoot impressive groups with good bullets. As stated, the bullets are the problem with the 7BR. Make up some good lightweight bullets and it'll probably shoot very well too..but won't likely beat a 30 in score shooting, where the 30's are dominant, because of the bigger whole it'll punch. The BR case is just too small to be able to take advantage of the BC of the heavy 7mm bullets at long range IMO. --Mike Ezell

That's something to think about But.....
The few thousand differance in bullet diameter is not the question?
I'm thinking Bc What's the BC of a 118 bib versis the 120 thats available. It should be higher with the 7mm due to length. I can't see a pressure problem unless we fool with a faster twist. Right now the 30br is being used with 17 16 and 18 twist barrels. Can't we use a slow twist in the 7mm br and acheive similar or better results?
Gaining Bc should more accuracy via less wind drift etc.
Not a lot but some. I'm looking at the wind drift maybe it
just isn't worth it and then maybe it is.

I shoot a 7BR in an Encore 14" SS barrel, I mainly shoot target, and a ground hog or two with 120 grain Nosler ballistic tip bullets. It will destroy a ground hog. Never tried it on deer but I can't see why it wouldn't do a number on one, within a reasonable distance. I hunt all summer on crop damage permits, not fond of it, but if I don't the farmer won't let me hunt during the regular rifle season. Next year I may just try to take a deer with the 7br. Have taken several with the 6br so why not the 7br. But never really gave it much thought till I read this post. Lou

I know this is kind of an old thread but I didn't want to start a new one. I was wondering this exact same thing, and why more people don't do it. Is it primarily because of the poor target bullet selection in the "light weight" range. Is there any good brass out there without having to do all of the prep work? Is the remington brass 'good enough' for pistol sillouette but not 'for score' benchrest rifle? Are people thinking that if you have to neck up 6br brass anyway, just as well go all the way to .30br ? What is everyone's thoughts on this? What twist rates should be used to primarily shoot something in the 110g to 120g bullet range?

Probably the biggest issue here - assuming BR quality bullets in the 120 Gr. or, < range: for bullets of equal weight, why put up with the same recoil as a 'thirty', which makes a bigger hole? For 100/200/300 Yd. competition, there just isn't big enough BC gap to make up for the price of recoil and the smaller hole. ;D RG
