Reading through this post again, I see the reference to speed being lost due to case forming. My experience and others that reported the same, was that previous accurate re-loaded ammunition shot well whilst being fireformed. This was the case in my 243AI.

Myself and the other guy with same set up both had velocity highs and lows and no grouping. I think that the issue will be more evident the greater the case capacity and the greater the volume gain.

Cast .308 paper patched goes to .314 very nicely.

A very experienced gun smith once told me that undersized bullets increase barrel wear.

At least you know the source of the trouble!

I have heard that Kriek bullets has done custom work.]]> Reloading Methodology Ds J https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6308 https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6307 Fri, 10 Jan 2025 00:20:55 +0000 Reloading Methodology Bushbuck https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6307 https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6304 Thu, 09 Jan 2025 12:56:03 +0000 Reloading Methodology Treeman https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6304 https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6302 Thu, 09 Jan 2025 06:10:01 +0000
Is it original, with just the chamber reamed, or with a new barrel? 

In many cases, grouping troubles has to do with a shot out barrel, or certain bullet weights, or certain bullet designs.]]> Reloading Methodology Ds J https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6302 https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6301 Thu, 09 Jan 2025 05:45:35 +0000 Reloading Methodology Bushbuck https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6301 https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6300 Thu, 09 Jan 2025 05:17:55 +0000 Reloading Methodology Ds J https://systemz.online/reloading-methodology/303-epps-reloading-data/paged/2/#post-6300
