does this scope still availbale ? good shooting DAN TEC

To Jr hello , you are right chambering lothar Walther need very stiff machine tool and mostly carbidereamer IF you want to keep your reamer a long time ( same time as regular High Speed steel reamer ) Lothar Walther are made in SS stel from 700 serial ( close to 17/4) they are not harder...

[ QUOTE ] Or you could just buy a Kestrel hand-held, two Oehler 35's, and/or a Model 43 and be done. [/ QUOTE ] if you happy with this stuff why not but dont forget that will be very strange to get real metrology result in the aim to compute something near the true with generic hobby design...

ok more informations first some tipes on the basics of instrumentation /measurement equipement calibration : for every thing /every stuff you use you need to calibrate exmple a thermometer probe will be dip in a bath od melded ice to check the zeo ( temperature of melted ice in water is a...

I not agree with you if you plan to measure ( metrolgy operation and not pretty display on a computer because display on a computer is NOT a true thing EXCEPT after to have check all step of the measure from adta aquisition , to A/D conversion to final sofware equation checking and software...

Matt from pure metrology I agree than 0.25 moa from scope turret is a bit " un accurate " measurement system BUT that a usefull way to compare and get a delta or gain valiue between two things 300 SMK a well know bullet wich is define by 6DOF equation fly so able to receheck with several...

Ok thanks for the imputs : 300 grain bullet w/ rated bc of .768 at 3005 fps. Rifle zeroed at 1500 yards and is 40" high at 100 yards. It took between 29 minutes and 31 minutes to hit around the gong. Elevation is 4888 humidity was about 30% temp was 50 pressure was around 30.0 wind...

on the short pitch in 0.338 cal take attention to the fact that engraving torque is a concern to check , if you go in short pitch you increase rifling angle value and you increase torque during engraving time so with long bearing bullet that will be a real problem of heavy fouling in the throat...

anybody can share elevation he get at 2000 yards with linked datas as muzzle velocity ? atmospheric pressure? air density ? in the aim to compare with 300 SMK good shooting DAN TEC

id that for home use I use mostly JBM sofware ( free on eskimo web site on line as field software oehler is good , sierra is good BUT carefully avoid transonic aera most software ecpet professional as MPM follow drag curve and drag curve is OK from 1.2 mach to 3.5 mach try to compute...

velocity is nothing is that not link with Bullet BC and air density over 3000 fps with a 250 gr in RUM seem a bit hot , rought computation ( 0.6 BC bullet as scenar lapua ) at 2850 fps ( easdy and safe ) allow to reach 1000 meters ( 1100 yards ) easy and super sonic don' forget too than some...

excellent bullet for what ? accuracy is worth fouling is worth throat life is worth bullet stabilisation is worth in most commun barrel the only excellent fact is to have sucess to sale so bad and so costly bullets good shooting DAN TEC

Gerard nice to meet you on the board , you are welcome good shooting DAN TEC

you are right Brownell 's make a slighty lenghend mag box wich can be fit with minor modification in REM700 receiver short to allow more "room " for WSM and 284 case lenght good shooting DAN TEC

in 7 mm short action go with 284 WIN that real IMP design and you get velocity in the 280 REM range without any fireforming or special costly die just carefully check feeding good shooting DAN TEC
