    Neck Turning - Inconsistent Results for a Newbie (Video)

    It looks to me like there is too much clearance between the case necks and mandrel. I can't get brass over the turning mandrel unless it's lubricated and turning. If the bit was moving, it'd only move out. I also only turn for 60-80% cleanup and wind up with less than 0.000 5" variance if I...

    Bullet specs for Shooter

    The copy on my phone gives numbers that look like the Miller formula actually. Given the stability threshold is somewhere between 1.3 and 1.5, and the 168 is ~1.8 with a 1:12 twist, you just don't need to know the bullet length to thousandths of an inch. You do need to have a number entered...

    Bullet specs for Shooter

    1.215" It's also listed in the Shooter Bullet Library for both the advertised and Litz ballistic coefficient. Litz has bullet diagrams in the back of his Applied Ballistics book. Berger lists their bullet dimensions in their reloading manual. Litz was compiling a length list, check his...

    Winchester Super Target (WST) shot-to-shot variation

    Sounds like the burn rate is about right for mid range 45 loads. It might still give trouble at the top and bottom of the recommended load range. If you're at the bottom of the load range, maybe bump it up 0.2 grains to see if it settles down. If you're at the top, go the other way. What was...

    Winchester Super Target (WST) shot-to-shot variation

    You should be able to keep pistol SDs in the teens, even with mixed brass and dropped charges. Even with meticulous preparation, velocity spreads will open up if the powder just isn't happy in the pressure range you're trying to operate it in. Slow powders may not be able to generate enough...

    Switch barrel savage?

    I'm working on something similar. Stevens 200 action switch barrel in an XLR chassis. I'm trying to use a Remington style shoulder on the barrel rather than the Savage nut. The idea is to have the headspace pre set. I'm going to mill a hex into the muzzle end for a wrench and use an action...

    Ideal 5.56x45 chamber for Berger VLDs seated at AR-15 magazine length?

    I wouldn't concede the point on bolt vs. AR accuracy as a factor in that type of competition. You can shop magazines for more length, or borrow another trick from the service rifle types and slot the front of the magazine. I've shot a lot of those 77 smks to 1km at 28.5 "Hg. They were...

    Leica 1600-B first hand accounts?

    I'm happy with mine. I range, then pull temperature, baro, and look angle for the ballistic ap. I have the simple Kestrel for wind. I use it to shoot plates and scope out new shooting lanes. Gives good numbers to 1100-1200 yards on a steel IDPA target in all conditions I've been willing...

    Thoughts on Quickload

    I'm pretty much with this guy. It's like anything else reloading, not 100% infallible, and should be used with care and a big dose of common sense. Combined with a chrono, it's brutally effective for load development once you get some experience with it. It's great for keeping you off...

    advice on first time reloading components for 223

    For a first time reloading shopping list, I suggest: Hornady 55 grain soft points. These are ~9 $/100 and more accurate than similarly priced FMJs. They also have better terminal performance. For temperature insensitive powders, Benchmark would be my first choice. It's extruded, but fine...

    Range Report Horizontal Coriolis - Computing Average Velocity

    Litz gives that equation as 0.00007292 radians/sec * Range in ft * sin(Lat) * TOF, with Time Of Flight in seconds. Using Range / TOF as the Average Velocity gives the same result if you substitute TOF = Range / Average Velocity into the Litz equation. So Yes, Average Velocity is Range /...

    sinclair comparator & 140gr hybrids and 140gr A-Max's issue...

    According to the Litz book, the Amax has a nose length of 0.689". The Berger reloading manual gives a nose length of 0.816" for the Hybrid. To get the front edge of the bearing surface at the same position, the Hybrid will have to be loaded 0.127" longer than the Amax.

    Dillon 650 question on powder charge volume

    I load precision ammo on the 650, and you can too. I also load high volume stuff, but the process is different. The more precision it becomes, the less like pistol ammo the process is. For real precision stuff, I only take advantage of the 650 features to size and trim the cases. The cases...

    Rifle Scopes 20 MOA Base for 5.56?

    The F TR guys wouldn't be overly impressed. I embellished, that's the firing solution for 1070 yards. We have another firing position 100 yards back, so it averages out. A waste of bullets to some, but I've learned a lot doing it and it's cheap entertainment. Hardest part was finding a place...

    Rifle Scopes 20 MOA Base for 5.56?

    Pretty much if its a wash on price, always go with the 20 moa base with a long range rifle. Just about any 30mm scope suitable for long range shooting will work with that base. I shoot those SMKs to 1 km pretty regularly and it's a 14.4 mil, 50 moa solution. You have to pull your muffs back...

    Rifle Scopes Vortex PST or SWFA SS for FFP Scope

    I have both and intend to keep both. I like the reticle better on the PST, and the zero stop is handy. My pet peeve is it won't focus below 75 yards. At 25, it's unusable. Some more travel would be good too. The glass is ok, but is bad enough I'm not really curious about it's higher...

    Should I choose.223 for a "trainer rifle"?

    The 223 is an excellent round to train for long distances. The distance and wind effects basically scale to the bullets ballistic coefficient, so it also solves the problem of finding an extremely long range to shoot at. Shooting a bullet with a 0.250 ballistic coefficient at 500 yards is...

    Help selecting a proper tumbler

    Definitely don't go smaller. The rotary tumblers are limited by their drive capacity, not the volume of the can. A 15# tumbler only has room for 2# of brass after the weight of the can, pins, and water is subtracted off the capacity. 2# of brass is only ~150 308. A 17# tumbler has twice...
