There is no better bullet than Barnes. Nobody else even a close second. I load the 7mm with a 120 grLazzeroni Lazerhead. Madeby Barnes for Lazzeroni. (a coated triple shock) You can get them from Midwayusa.com. I take 7mm Weatherby cases (has to be Wby headstamp)and fireform them in a 7mm Rem Mag gun (10 gr of Bullseye and cram cornmeal on top with a little cotton ball to keep it in place,no bullet) then trim to Rem mag length. My load is 83.5 gr RL 22 and velocity is 3850 fps with no pressure signes. (using a browning BPR 7mm Rem mag) Yes the Triple shock grooves in these coated bullets are awesome. Also these solid copper X bullets hold together 99+ percent, always expand double diam and nearly always go out the other side of a deer. Seat them .050" from the lands (starting) for best accuracy. Yes this load in this rifle shoots well under an inch @ 100 yards.

My son's middle name is Remington!

Thats increadably impressive numbers your talking. E-mail me more about that technique you use with the WBY brass. Last time I got some brass off E-Bay, it had some 7mm WBY MAG headstampted brass in it. Would love to get a 3800 fps load.

Here are my load stats now

7mm Rem Mag
Rifle- 700 ADL
Case- Frontier or W-W
Bullet- Barnes TSX 140 gr
Charge- 67gr RL-22
Primer- Federal Match Large Mag Rifle
FPS- ~/= 3200 fps
I'm shootin perfect clovers at 100 yds.

Nice Middle Name on the kid!!!!! I'm a Remington Slut! Only thing I shoot other then my Grand Daddys 32 win spcl. You gotta understand that though.

Rick
I grew up there in NC Northern MO. 10 mi N of Salisbury. I too was weaned on beanfield fence rows. 1/4 mile shots were the norm and hard to get closer. 2" @ 100 yds is a scrap/loaner gun there.

It is just fireforming the 7mm Weatherby in a 7mm Rem mag chamber. The rem mag chamber is slightly larger than the 7mm Weatherby but the Weatherby brass (and it has to be Weatherby headstamp not RP or Win etc) is thinner so after fireforming you now have more capacity. I take a fired 7mm Wby case, a mag primer 10-15 gr of Bullseye powder then fill with cornmeal and pack a cotton ball on top to keep the cornmeal in place and firein the 7 rem. I then trim to 7mm Rem specs and load. You can trim the case a little first if you want but I don't go full short length.

Also I use the Lazzeroni Lazerheads. (lazzeroni.com)They are made by Barnes dimensionally undersize and 3 grooves cut in them then Robar plates them with "NP3" for lube and to bring them back to size. Then Lazzeroni sells them for $1 apiece. Midwayusa.com $53 for 50. I have worked up to 85 gr of RL22 with NON-Magnum benchrest primers (they have the little capitol B on them) but came back to 83.5 because I need the accuracy. after 5 loadings the primers are still tight @ 83.5.

If anyone has a lot of time you can try front ignition loading and reduce recoil, narrow the velocity spread and increase accuracy, but the max velocity does not seem to rise for me. There is a good explanation in the 10th ed Cartridges of the World book page 482. Oh yah there is less muzzle flash and the cases are to hot to pick up with wimpy fingers. (another story)

I tried multiple powder, primers and brass and could not find a combination with the accuracy I want. I recently started loading the Nosler AccuBonds and can't belive the accuracy and nock down power of this bullet.
