Re: 34" 300 win mag When bullet drag overcomes barrel pressure, velocity falls off. Read Dan Lilja's article here: http://www.riflebarrels.com/articles/bullets_ballastics/long_barrel_velocity.htm It gives a good "feel" for the subject. I have a 338LM 38", barrel length pays off. Also...

Re: 7mm rem mag build Select the bullet you wish to shoot. Go to the Mfg's website, the recommended twist is usually there. If in doubt, twist a smidge faster than recommended. I use 9 on 180 and 189Gr 7MM's, but very high MV's.

Re: Competition Die Set? What they have done for me is remove another excuse for my own inconsistency...........

Re: Krieger Offering 5R Rifling Most custom barrels I have owned foul little and clean easily. 5R may have advantages in certain applications (I like mine), but once you get to 1/2-5/8MOA (which is doable with either), the advantages have to be perceived elsewhere. Most 5R barrels I have seen...

Re: 105 AMAX moly wont shoot in my .243 Moly can change barrel time, and therefore accuracy. Plastic jar inside the tumbler keeps the tumbler clean, if it is a tumbler and not vibratory......

Re: Best way to convert CDL to 30-06 Heavy Barrel? If just looking for a shooter, inspect the lugs, if both are bearing evenly, buy the rifle, shoot it. If it shows promise, add the desired whistles, and work up a load. If it doesn't, sell it and do it again. You can lose $50 several times...

Re: .338 Lapua Ackley Imp I've had good results with VV N570, but it's hard to find. My LM isn't AI, but has a very long barrel, 37.75", set up specifically for 300Gr bullets. MV's w/VV N570 are very good (>3000), and 1/2MOA or so accuracy. Settled on best ladder results. Have good loads in...

Re: 7mm projectiles Gilly Haven't checked the numbers, but a useful exercise is to run JBM at 1800Yds and at 1820-1850Yds. Observe the time of flight numbers and the additional drop from which one can estimate (or calculate) the vertical speed of the bullet. The vertical becomes a...

Re: 1000 yard scope power If shooting man sized targets FFP works well. If shooting MOA sized targets, I've found reticle size to be problematic with FFP reticles. Reticle tends to obscure the target Powers above 20 are seldom usable here because of mirage. JMHO

Re: tumbler took a shit on me I've had similar problems with other tumblers. Since I have a motor shop, I did an autopsy. Dust from media deposited in the motor bearings over the years, and gradually increased the torque requirements of the motor. I added to the problem by leaving the lid off...

Re: Loctite question Does anyone know if Loctite application requires the use of the lubricated screw torque vs. the unlubricated value? Most larger fasteners require a 20-40% reduction in installation torques when lubricated. installing to lubed fasteners to unlubed torques causes thread...

Re: Trouble justifying USO I have and like both. USO may be a tad bit sturdier and less variation unit to unit. If you are trying to sight small targets or tiny groups at long distances, the FFP reticle may be too large to accurately sight on the corner of a box or the tip of a diamond at...

Re: My 1000 yard dope was off while hunting "(HELP)" JBM indicates: 1000 -0.0 -0.0 35.3 3.4 2111.6 1.891 1781.7 1.176 207.0 19.8 1020 -6.2 -0.6 36.9 3.5 2094.2 1.876 1752.6 1.205 212.1 19.9 For stated velocity @1000Yds, 8500' Pressure altitude. Impact point varies 6"...

Re: My 1000 yard dope was off while hunting "(HELP)" Atmospheric conditions can be a big factor, and error increases greatly with range, as vertical component increases. Our problem (with white tale), was ranging. My Swaro has trouble with white tale beyond 600-650Yds (operator error?). It...

Re: 140 Amax out to 1000yrds May be a little late, but Moly AMax's work well @ 3100FPS in my 6.5x55. I found them to be as accurate or slightly better than JLK's. I havn't tried Bergers in .264". Sub 1/2MOA at @1000 when I do my part.

Re: Neckturned Chamber? +1 for C Dixon's reply. Has application for very long range or BR, but limits your options considerably. JMHO Been there

Re: Want to see how well your rifle really shoots? Very interesting posts. I'll have to do some thinking about the data presented. It appears that some of the bullet hole descriptions described above represent marginally stabilized bullets. Since the linear velocity degrades more quickly...

Re: Any experience with Barnard P-Chey action PS: Bases, action wrenches, other accessories available from MT guns. Also high quality stuff.....

Re: Any experience with Barnard P-Chey action Don't have a P-CHEY, but have a P and 2 PL's. 6.5X55, 338LM, and not yet built 7MM-338LM. I'd add to Later's statements above (with which I agree) 1) Best trigger I've ever shot. 2) Very fast lock time 3) Very high quality from threads to bolt...

Re: 7 RUM Neck Bushings Thanks Brain. Correct on SAMMI 'Minimums' chamber, but I don't know how to define it yet. I loaded assembled dummy rounds for throating, and have measurements for assembled rounds, but don't know how to equate it to bushings. Should I just wait and measure fired...
