Trying to neck size with an FL die only "works" if the case has a goodly amount of taper. The 243 is a relativity straight case, thus simply backing the FL die out a touch will still allow the die to contact the case body. Once the die makes contact with the case body, you are no longer Neck...

Cartridge : .270 Win. (SAAMI) Bullet : .277, 140, Nosler BalTip 27140 Cartridge O.A.L. L6: 3.320 inch or 84.33 mm Barrel Length : 22.5 inch or 571.5 mm Predicted Data for Indicated Charges of the Following Powders. Matching Maximum Pressure: 64000 psi, or 441 MPa or...

Case weight has little to do with case capacity. There is no direct correlation between the two. Just because a case weighs more, does not in any way mean it has less capacity. See here. Example, the S&B case weighed 3.2gr less than the WCC yet they both had the same case capacity...

I coat my cast bullets with HI-TEK coating. Foe me it seems a lot easier and less of a mess.

Case weight is a full grain less or H20 internal case capacity is a full grain less?

What are the details of the load, powder, primer, OAL, distance from lands etc.?

It is and it is not. Quickload for example uses the total volume of H20 from a fired empty case. Some like Nosler use the "usable Case Capacity" which is what is left after the bullet is seated.

When posting QL results do this. Your post will be easier to read and look like this. Cartridge : .222 Rem. Bullet : .224, 40, Sierra Blitzking 1440 Cartridge O.A.L. L6: 2.130 inch or 54.10 mm Barrel Length : 20.0 inch or 508.0 mm Powder : Norma 200...

It's tough to beat the 286gr Partition and Ramshot BigGame.

Here it is in an easier format. Also QL will be more accurate if you supply the actual case capacity in grains of H20 of a case fired in your rifle. Cartridge : 6.5 Creedmoor Hornady Bullet : .264, 100, Nosler BalTip 26100 Cartridge O.A.L. L6: 2.775 inch or 70.49 mm...

Cartridge : 6.5 x 55 Swedish Bullet : .264, 120, Barnes 'TTSX'BT S 26430 Cartridge O.A.L. L6: 3.150 inch or 80.01 mm Barrel Length : 22.0 inch or 558.8 mm Predicted Data for Indicated Charges of the Following Powders. Matching Maximum Pressure: 62000 psi, or 427 MPa...

Here it is in an easier to read format when brought up to 62K psi in a modern action. Cartridge : 6.5 x 55 Swedish Bullet : .264, 120, Barnes 'TTSX'BT S 26430 Cartridge O.A.L. L6: 3.150 inch or 80.01 mm Barrel Length : 22.0 inch or 558.8 mm Powder ...

I know nothing about your rifle, but most 6.5 data is very conservative to accommodate older 6.5 x 55 actions. I load my modern action M-70 and CZ 550 to higher than the anemic 55K psi listed in most manuals. Here is what QL calculates if you bring your pressures up to 60K. Again, duno...

Here it is in a much easy to read format. Cartridge : .270 WSM Bullet : .277, 150, Nosler Accubond LR 58836 G7 Cartridge O.A.L. L6: 2.860 inch or 72.64 mm Barrel Length : 24.0 inch or 609.6 mm Predicted Data for Indicated Charges of the Following Powders. Matching...

Note that the pressure does not start to rise until the bullet is seated extremely deep, over a Quarter of an inch off the lands. I have no rifles that can be seated that deep. YMMV. Back to the original question. As case capacity is reduced so is pressure until the bullet is seated well...

Don't know about your "Symptoms", but here is actual pressure tested data.

Actually it's does not affect pressure due to case capacity in a bottle necked rifle round. In fact the longer the OAL (more room under bullet) the higher the pressure. Here is why. From John Barness of Handloader Magazine. Reducing OAL decreases peak pressure, for two reasons. The longer...

I received a reply to my question from Nosler yesterday. In response to your question: That is the remaining capacity after the bullet is seated. Have a great day, Nosler FAQ Their reply answered the basic question, but also left a few questions unanswered. Why is this data included...

In you new #7 manual you list "Case Holds" "XX.X gr Water" In my experience there are two type of H20 case capacity measurements. One being "Case Water Capacity" which is the weight of water in grains that fits in the case under the seated bullet. The other and more useful to the...
