Re: Len's new 7 LRM - first day at the range
Thanks for a great thread, Len. Thanks to all who contributed. I just ordered a 7LRM reamer from Genwerks today to build one for myself.
Over the past 10 years I've become captivated with the 7mm/.284 bullet and the factory casings pushing them. Living and hunting out west has made me a follower of the long range hunting order. My first rifle purchased was a Browning BAR Safari II w/BOSS in 7mm Rem Mag. Great gun, super accurate, killed several animals, great novelty rifle but not much good for long range hunting. Since then I've built other rifles around the 7mm Rem Mag, 7mm WSM and the 7mm Ultra Mag. The 7mm Ultra Mag being the most potent and accurate at extreme distances. On it I used a factory Remington 700 barreled action, Wyatt's extended box magazine, Timney Trigger and a VAIS muzzle brake all bedded into an H-S Precision sporter style stock. At an elevation of 5,000 feet and a temperature of 50 degrees it pushes a 180 grain Berger VLD at 3,250 fps. 3/4" to 1" three shot groups at 200 yards from a bench. Load is 92.0 grains Retumbo, Fed GM215M with a COAL of 3.820". From first hand experience I can tell you this bullet and cartridge combination is way to much for mule deer and pronghorn antelope.... like shooting prairie dogs with 95 grain VLD bullets from a .243 Win. But it's awesome on big bull elk and Alasken moose.
Now it's time to tame it down a bit and try this new 7LRM. Again, thanks for all your comments. Very helpful.
