FL vs neck sizing

[Walkalong]

The FL die is still going to touch the body, and if it moves it in enough the shoulder moves forward until the die touches that as well, which can cause issues. I would recommend a neck die only or minimal sizing with a FL die.

Loose depends on the chamber and the die. Most people chasing accuracy have match chambers which tend to be tighter. And of course it depends on what die and how it was made. A couple of sources at least will cut sizers based on your brass. Harrells makes several sizes of FL dies in at least one caliber and match it to your brass.

Yeah that's what I understand. It also seems to me that full-length sizing might actually help to create a smoother, more consistent start pressure. Seating off the lands with fire-formed cases may help for the same reason.

If your reloading time is your get away’ so to speak then there’s no better way to IMO than using a quality FL bushing type die.

Good stuff

No, Nothing gets serious until the case fills the chamber, Again, I have a 30/06 that has a chamber that is .002" longer than a field reject length chamber meaning the chamber is .0116" longer than a minimum length/full length sized case. It takes time for the case to form to the chamber. I always do better when I reduce the time it takes for the bullet to exit the barrel. I* am the fan of the running start, I want my bullets to have that jump.

I get by with Wilson neck sizing equipment for my bolt rifle but with an undersize neck I have to buy premium, necked brass to avoid jamming. Bart B. has always said that most of the top shooters do a full-length size and I have no reason to doubt him but I've never really understood why this would be.

Bart B. has always said etc. etc. that has never made any sense to me because there has to be at least $1500.00 dollars difference in the cost of 'the bench resters rifle' and your rifle. I have purchase 5 very heavy barrel blanks with plans to build something called a bench rester rifle. The first one will to Alabama with instructions. I will instruct the new owner to chamber a round, aim and then pull the trigger. After firing the first round set the scope of the first hole and then adjust the scope to the center of the target. I will tell him he should expect the bullets to make one hole and I will instruct him to make the same adjustment evetime he changes ammo. I will send him at least 20 different loads of 10 rounds each with 20 different head stamps.

Full length sizing: I know the length of the chamber from the shoulder to the case head and I will have to form cases for both rifles.

I will not have $450.00 in both rifles and that depends on the stocks.

Good ole Bart B..

minimal sizing with a FL die...

I can remember getting a slightly larger sizing die from Wilson, for fired cases. The full-length sizing as described by Bart B. is making more sense now thx

Bart B. added that part about 'a slightly larger die' years later if he made the claim. An experienced reloaders should know how to avoid sizing the case back to minimum length/full length size.

Eventually everyone FL sizes
