[QUOTE="Stonewall2, post: 163122, member: 6935"] I phoned Weatherby over twenty years ago on the fore end pressure question . I was told that they used 12 -15 lbs. -the higher # on the larger Mk V calibers. One .240 with a #1 barrel that I bedded for a Br shooter shot 5-5 shot averaging .420 at 100 yards in a hunter match 6 X scope . This was with the barrel bedded for aprox 2" forward of the receiver ring and floated the rest of the way. I had a 7mm #2 contour barrel Mk V that would shoot .3 for 5 at 100 yds. (160 Nosler factory loads ) after I cleared the top edges of the barrel channel by .010 + . That's all the bedding work required on that rifle. Unfortunately I lent this rifle to a friend for two days hunting and it came back with rust in the barrel - I hope that I learned something from that !! The point is that both methods work well done properly . A point that most forget is mounting the scope in a stress free manner after the bedding work is done. You can screw up a excellent bedding job this way......... I torque the front screw at 40 in/lb -back screw 25 in /lb. I check this with a dial indicator after I bed the rifle. Another point -when bedding under the barrel shank mask the barrel .010 for aprox .3 below the stock line parallel to the top edge of the stock . This allows it to heat up and prevents POI change -flyers. It also lets the barreled action drop free when the screws are removed-easy to check bedding with dial indicator. The ppressure point should have a V cut thru the center so that it is not bouncing on a center point and not returing to the same place after each shot-think V blocks. Even with epoxy I leave a small strip down the center masked. I read this first in Mike Walkers comments about Rem 700 bedding in Gun Digest years ago. He said then to slightly relieve the center of the pressure pad . Glenn [/QUOTE]
