[QUOTE="daveosok, post: 24061"] Rifle type Remington action, trued and blueprinted bolt lugs lapped Caliber 7 MM STW Barrel Lilja 34 inch Stainless Steel 4 groove 1:9 twist Stock Choate Ultimate Sniper, bedded Firing Pin Speedlock firing pin and spring Trigger Remington, precision ground, 1.5 lb pull Muzzle break Custom my design OVER ALL LENGTH info OAL 3.042 (Stoney Point measurement tool) TIP TO BASE OAL 3.755 All bullets seated at lands. Temperature 50 degrees Barometer 30.34 in steady Humidity 54% Dewpoint 34 Altitude 429 ft Distance for tests 200 yards measured. All groups 5 shot groups or as noted otherwise. All cases Remington, all primers Fedral Match 215'3. Oehler 35p used for velocity results 25 feet in front of muzzle. FIRST GROUP POWDER RL - 19 GRAINS 71.4 AVG VEL 3347 HIGH VEL 3382 LOW VEL 3314 GROUP SIZE 2.265 2 fliers SECOND GROUP POWDER H4831 GRAINS 74.0 AVG VEL 3315 HIGH VEL 3334 LOW VEL 3328 GROUP SIZE 3.125 THRID GROUP POWDER N560 GRAINS 75.0 AVG VEL 3460 HIGH VEL 3493 LOW VEL 3428 GROUP SIZE 1 **3 SHOT GROUP FOURTH GROUP POWDER N165 GRAINS 77.0 AVG VEL 3442 HIGH VEL 3479 LOW VEL 3411 GROUP SIZE 1.0 2FLIERS*CAUTION TIGHT BOLT FIFTH GROUP POWDER RL-25 GRAINS 80.0 AVG VEL 3524 HIGH VEL 3556 LOW VEL 3495 GROUP SIZE 3.5 CAUTION TIGHT BOLT SIXTH GROUP POWDER H1000 GRAINS 81.0 AVG VEL 3415 HIGH VEL 3429 LOW VEL 3402 GROUP SIZE 1.375 2 FLIERS SEVENTH GROUP POWDER H870 GRAINS 92.0 AVG VEL 3426 HIGH VEL 3471 LOW VEL 3406 GROUP SIZE 1.125 2 FLIERS 8TH GROUP ****168 GRAIN JLK'S**** POWDER RAMSHOT MAGNUM GRAINS 79.0 AVG VEL 3197 HIGH VEL 3223 LOW VEL 3173 GROUP SIZE 2 2 FLIERS 9TH GROUP ****168 GRAIN SMK'S**** POWDER RAMSHOT MAGNUM GRAINS 79.0 AVG VEL 3171 HIGH VEL 3191 LOW VEL 3147 GROUP SIZE .625 2 FLIERS More testing should produce tighter groups. N560 showed the best possibilities with more load development. Overall conclusion Lost River Bullets will work, however it will cost you and arm and a leg to find the right loads if you dont get lucky the first go around. When working up loads with this same rifle using Berger 180 grain I used load data from Accurate Reloader website. More load development should produce better groups with LRBT. My thoughts are for the cost and what they claim to be able to do (LRBT) the Bergers win hands down as they required no bank loan to procure enough bullets for testing purposes. I do like the LRBT and will order some more but for the low budget reloader, he or she may see better gains using Sierra, Berger, or JLK's. Lost River Bullets require finicky settings and I'm sure I will dump a few hundred into buying more to find the correct load. **********DISCLAIMER************ Information contained herein should be used as a reference only and all loads should be started 15% below stated weight.
