Weighing your powder as consistently as possible is the biggest thing you can do towards getting good results from your reloaded cartridges. I've taken factory cartridges and pulled the bullets, weighing the powder from all the cartridge's and dividing the total weight by the number of...

I haven't use my Forster Competition seater or has it seen the light of day for years, since I got my LE Wilson Micrometer seating die and an arbor press. I used to have that kind of issue with 168 and 175 SMK's as well. I used the Forster seater on a Forster Co-Ax and thought there shouldn't...

That press is a LOT of $$$$$$$$, which is ok if you're a high end competitor. . . or, money is just no object. :eek:

Yeah, I was expecting maybe 1400 or so if I was lucky and have a Krieger barrel I ordered about a year ago in the closet waiting to be mounted. I don't shoot mild loads either, close to the max very often. But, I do keep a close eye on barrel temperature using a temperature strip mounted on...

Usually, I clean my 6.5 PRC at ~100 rounds. As I approached 1900 rounds fired and with a new barrel waiting to be mounted, I've let the cleaning go ~300 rounds thinking it's probably the last round of use for this barrel. But, Sunday's results make me wonder just how long the barrel will keep...

Even with a COAL of 2.955 the bearing surface on the 153.5's is well into the donut area, which is something of usually try to avoid. But . . . we'll see. :giggle:

If you sort by your case's headspace, each batch should have a pretty consistent AOL =<.001", if you sort them in groups with .001" difference. But, of course, there'll be more difference between the batches. And since you don't anneal, there can be variance in springback that can add an...

I also use a Tri-Way. There are 2 key things that contributes to consistency, or lack thereof. As you are aware, the Tri-Way indexes off the shoulder, so if your cases head spaces are not consistent, your trim lengths will not be either. Add to that the second thing: the amount of pressure as...

Thanks. Last August I did find a load that looks very promising for the 153.5's, where I got 5 shot groups very much to those 140 hybrids. But I haven't really tested the load to really see if I can get those results on a consistent basis. I had loaded 57.4 grs of N565 (COAL 3.096 :eek: -...

Why not use check weights like this???: https://www.lymanproducts.com/scale-weight-check-sets

Yeah, I know the following is not the thread's listed projectiles ( do have 153.5's, but not finished load development yet with them), but I thought some viewing here might like to see what some 140 Hybrids did for me out of my RPR (fooling with tuner adjustments 6.5 to 4.0). 5 shot groups (a...

Nope, you're not the only one. I've got 5, three of which are adjustables so that I can keep them set at the seating depth that I've found works best. :D It's like I have more than one caliper, each fitted with different comparator (I hate having to change attachments repeatedly). ;)

In terms of internal ballistics and for a very basic understanding: Seating depth, powder charge (barrel timing for bullet exit), consistent ignition. A good barrel and receiver helps a lot too. ;) Internal ballistics is very complex with many factors involved. Like, just look at what...

There was a time when I was "chasing the lands" to maintain my good results on paper. I measured and tracked my throat erosion and would adjust my seating to keep the same amount of jump. It frustrated me as it wasn't working and tried to figure out why. After some time and reading what...

As mentioned, chamfering virgin brass is a huge help in seating bullets. . . even boat-tail's like 143 ELDX's. The factory trimming to length often leaves a significant burr on the inside of the mouth. Lubing doesn't really help when there's such a burr on the inside of the mouth. I don't...
