7 mm Rem Benchrest

Looking to load up for XP100 any one have a favorite bullet weight. He probably won't hunt with it just wonts to shoot it.

It's been quite a while since I used the 7mm BR, but I went with the 120 - 130gr bullets.

I hope you have cases, or are ready to form them. The death of the 7mmBR was (to me) very sudden. I intend to try forming cases from both 7mm-08 and 6mmBR and see how it goes.

Anything 140+ and believe it or not the Remington 150 Core-Lokt shot as good as anything out of my XP and used to be able to buy them in bulk from Midway. IMO H322 is "the" powder and Federal Benchrest primers to light em up.

I'm a big fan of 22 BR in a rifle! My friends all had Savage Target models in 6 BR. I was the outcast with a tuned 700 action and a cut off and rechambered barrel from a Winchester 70 "Coyote".

I was slow to getting on the firing line. The game was called "Whomping Rocks". Place a football sized rock at unknown distance (325+yards) and take turns shooting it. Because I was slow, I missed the first three relays. When the 105/106 grain 6mm bullets struck, a small (thumbnail sized) chip would fly off. When my 50 grain 22 caliber Combined Technolgies bullet hit it at 3900 fps, it dissolved into a pile of pea gravel! Like Roudolf The Red Nosed Reindeer, I was never invited to play that Reindeer game again!!

I formed my brass from 6mm BR Lapua Brass. Because I have the old Remington Chamber, I had to turn my necks to .010 thickness. That took hours for 200 brass. I thought about having it changed to 22BR Norma with the "No-Turn" .015" neck, but after seeing how it shot, I didn't want to change a thing.

FROM THE HORNADY SILHOLETTE LOADING DATA PAMPHLET from 1983

The 130 Spitzer Soft Point bullet isn't listed, I would use the 139 Grain data.

Case Rem BR (I use Lapua 6BR necked up)[reformed rifle cases can need huge amounts of work to fit in a Bench Rest Chamber!]
PRIMER Rem 7 1/2 (Sm Rifle Mag)
Powder: IMR 3031
25.4/1900fps
26.5/2000fps
27.0/2050fps
27.6/2100fps
28.1/2150fps
Barrel Length 15" /1:10 Twist
COAL 2.33"

On single shot guns you are not required to crimp! The neck tension should keep the bullet in place. However, I always use a medium crimp or .004" Neck Tension depending on the die set used.

No data was in this pamphlet for IMR 4064.

The loads in this pamphlet are some of the best starting data I've found on the cartridges that I load.
