Customs have several advantages. First - consistency is likely to be good. This isn't necessarily just fantastic accuracy, though it's likely to be pretty good. Some of them will put multiple loads - powder and bullets - into the same place, over and over, year after year, even if ignored for...

You might also consider that when you adjust the die to the general dimensions, it isn't really set to your chamber and may not be actually bumping the shoulder back at all. (Usually is, but not always.) If it doesn't bump the shoulder, the brass that was expanded in firing still has to go...

Good comments. I'll add that brass is made by machines, and machines wear over time and use, so one batch of brass may differ from another in the same caliber. Also, it depends how picky you are. I'm pretty picky, so I sort mine by neck thickness variation. I prefer Winchester to Remington, but...

In my pursuit of the elimination of flyers - it couldn't be me! - I changed two things. I bought benchrest primers and measured case necks. John Barsness thinks he can get the same results with a bright light and a magnifying glass. Apparently, he can see thickness differences. I haven't tried...

I measure caseneck thickness variance with an RCBS Casemaster. If a case varies more than some arbitrary amount - I use 0.0015" - there's a noticable change in group size. I don't necessarily throw away those that vary 0.0025, but I sure don't use them for load development. There's been a real...

stinky, You seem to have more than one question, and not all revolve around headspace. Yes, you can buy tools to measure headspace. I do, but many people don't bother and still "adjust" it fine without actually "measuring" it. "Headspace" is the amount of room left in the chamber for a...

Thanks, 2ndtimer, that certainly has the ring of truth. Jaywalker

Just wondering, Nosler... How did you decide on the 130g weight? Was it something that's easy for you to produce for some reason? Jaywalker

True enough, but it's better than 300 rounds of Swift or North Fork! Jaywalker

Blammer, I agree that a larger case requires more than a couple of tenths of powder change to make a difference. OTOH, I haven't read about any of your changes to a couple of important factors: seating depth and primer. IMO, these are much more likely to produce change than simply changing...

What kind of powder makes a lot less difference than the bullet and the seating depth. I'd pick a powder that's appropriate for the case and stick with it - just change the seating depth on your bullet. If that doesn't work, change the bullet and start over. I get good results with this method...

Blammer, I agree with you about the five-shot groups. If I shoot three and they're all together, then no harm, no foul. That almost never happens, though, and then the "two in, one out" leaves me questioning which is the "real"group. "Four in, one out" tells me something, as does "three in, two...

I might be able to drive a 130g bullet fast enough out of my 6.5x55 to need a bonded one - maybe. It is not a 264 Win Mag. The question is whether I'll pay over twice the price for its marginal advantage, and I don't think so. I would pay for 120g bullets' velocity advantage, but since I haven't...

If the BC isn't just a misprint, it could be the difference between theory and reality. Nosler likely wanted a bullet with higher BC and designed for it, but testing showed more drop than theory, and they listed the BC as corrected by teting. Drag isn't always as predictable as looking at it...

deerndingo, you're welcome. I haven't ordered any Nosler yet, but expect to be the same quality as the Lapua I do order, so I'll treat it the same. Personally, I don't bother to resize Lapua, but since it comes bulk-packed, I do expect some neck deformation and therefore run the neck expander...

I thought Nosler brass came already chamfered. Do you remember if it was? Jaywalker

Cazador, Good practice to cycle them. I do the same thing, but with a dummy round I keep for awhile (in case I've made mistakes on measurements, bullet types, etc). I saw your post on another forum in which you were told Nosler's had some acknowledged problems with tips. Okay, could be true...

What kind of rifle? Jaywalker

Actually, though I have neither, I think I'd lean towards the 338 Fed for several reasons. First, there's liable to be a few factory loadings, at least initially. Second, I don't care for fireforming brass, and the few makers get quite a bit of money for 338-06 brass. Third, you need, I...

CW, When using the Stoney Point tool that pushes the real copper bullet into the lands, I only use that bullet for measurement one time. Once it's been pushed into the lands and scored, you can shoot it without concern, but it will no longer yield valid measurement results for subsequent...
