Default 7MM BR Sisters

I got those work from home quarantine blues. May as well take some pictures and tell some stories.

Not long ago I posted about a XP-100 I found. I got some discouraging feedback about how difficult it is to make brass. It turns out that making 7MM Remington BR brass from Lapua 6MM Norma BR brass is quite simple.

Anyway, I recently stumbled into a dream gun... my favorite model in my favorite caliber, never commercially available. It's a Model 700 BDL Varmint Special in 7MM BR. Imagine that. The barrel is factory Remington, converted from a 7MM-08. All the factory logo on the barrel conveniently ends up underneath. Sleek and stealth. The gun is actually a switch barrel setup, and I also got a 308 barrel, 22-250 barrel, and the tools to switch barrels at home. I've got 308's and 22-250's, so this will be a dedicated 7BR.

The gun doesn't disappoint. Maybe the funnest range toy in my toy box. I'm still working loads, but she's got some real potential. The XP-100 is also pretty sweet. The target in the center on the bottom is 5 fire form shots out of the XP.

I took the 700 out to 200 meters and gave it a go. I'm still learning how to deal with wind and stuff, but this should be a dandy long range tool.

That's a good looking rifle and you did some nice shooting.

I've never heard of 7mm BR Remington so I had to go look for my book and learn something new. Wow, had no idea. Introduced in 1979 and declared obsolete in the early 2000's.

It says it's essentially a shortened .308Win case, necked down to .284 inch.

I had an XP100 in 7mm Benchrest for 15 years. Shot it in silhouette matches. I sold it to a forum member along with its scope, cases, bullets, dies, and some loaded ammo. It is a wonderfully accurate round for hunting or competing. I used to load 139g/140g spitzer bullets.

The 7mm BR pistol was the preferred gun for the long range event at the Masters International Shooting Championship for nearly 40 years. Various variations were built, in 6mm, 7x47, 6x47, and numerous 6mm and 7mm calibers, adapted from Silhouette game. Front grip, rear grip, center grip. Several custom gun makers built guns to order for customers. Frank Glenn build many for the top competitors, and he was one himself.

I just got a 16" barrel in for my Encore pistol in 6BR. Haven't taken it out yet. I hear the caliber is tops in long range rifle competitions.

Lapua 6MM Norma BR brass didn't exist 35 years ago so you are very lucky

Here is an inexpensive way to learn wind. First lets make a chart. Whatever the Velocity is goes in the title line With gun and Temp and distance to zero. Second line:
Distance, Elevation, Wind 3, Wind 5, Wind 7

Note on elevation & windage: I just wright in the clicks for the scope, buy some charts have inches. There are numerous ballistic calculators on line to get the data from. I use the Sierra ballistics program on my laptop.

After the chart is made, fire a well aimed shot at the zero distance. The wind will blow the bullet somewhere. Looking at the wind chart for that distance will tell how much. You now know what the wind feel like and how much that wind will move the flags, the trees and the grass. Make corrections to your scope and shoot all you want, when done shooting at that distance be sure to return scope to the zero settings!

Why 3, 5, & 7 MPH? Below 3 really won't matter! The rest is simple arithmetic. The click value of the scope is just added to figure higher wind values. Example 10 MPH is the 3 value + the 7 value! That's 10! 12 is just the 5 value plus the 7 value! 15 is 5 +5 +5 value. You get the idea. I started with 100 yard increments, and found them to be wat to course, and 10 yard to be way to fine, I ended up with 25 yard increment, and for my long range guns, I went out to 1160 yards. (that is what fit on a piece of paper!!)

Environmentals: The most important is wind (covered), the second is your choice of Temperature or Barometric Pressure, the other is third. Unless you regularly shoot beyond 800 yards "spin drift" and the earths rotation won't need to be considered.

Good news/Bad News: The ballistic coefficient and the velocity are what determine the trajectory of all bullets. It would be hard to find ammo combinations, that more than one ammo would use the same chart!

Feel free to PM me if you have questions.

Shot story of how good this works (and how lucky I am too!) I had a recently acquired rifle (6x284 on a 700 action) and had developed a pretty good load for it at 100 yards (70 grain Sierra Blitzking & IMR 4931SC). A match came up, and I decided to use this gun. I made the first of these charts using Hornady's on line ballistic calculator. But the only distances I had were 100 thru 800 yards in 100 yard intervals. and 5 & 10 mph winds.

The match was as follows; one target per round, all targets at same distance, Distance unknown, no wind flags! Only one shot! NO SPOTTERS!

First round, target: 2 liter pop bottle of orange soda, hanging by fishing line 3 feet off ground, tall weed all around, so you couldn't gauge by someone else's miss! When my turn came up, I used the cross hairs to figure the range, (because I knew size of my aiming dot at distances, 1/2 the width of the pop bottle) I guessed the range to be just over 500 yards (later lasered to be 523) I felt a very slight breeze from the right, so my sim point was half way up and just in from the right edge. I was the 8th shooter and the first to hit the target. 2 other shooters hit their first target! Second target: same everything except it was a 20 ounce bottle of Diet Coke. I knew from the first shot to aim dead center. I was the first shooter and the only person to hit the target. I won $60! I was allowed a free shot at the 3rd target, a 6 ounce bottle of Coke, which I missed. everyone could shoot at these targets for $5 per shot. The 4th target was a golf ball! I quit shooting, but I saw guys drop $100 @ $5 each truing to hit those targets. Only one guy hit a golf ball, the promoter probably had $1000 that day!
