| Well I finally got a decent day with slight winds so I tested my loads for my 204 Encore barrel with full lenght RCBS dies and Lee Collet Neck Sizing dies. It was a limited test because I had only 5 rounds that were not full length sized that I used with the Lee dies. I used 27.8 grains H335 for the 5 neck sized brass, and then loaded 10 rounds with the same amount of powder with the fully resized brass, which is my best load as of date. All were seated at 2.350". I shot 3 five shot groups so I had 2 of the full sized and 1 of the neck sized. The full sized groups were about 1 inch or a little better and the neck sized was less that 3/4". I was truely amazed at the difference. And am going to order a set made for my 300 RUM. |

I did the same prep with both batches. Deprimed with universal die, tumbled, worked primer pocket and flash pocket, cleaned neck, sized, trimmed as necessary, deburred inside and outside of neck.
I will definately play around with it and shoot more, but the difference in the groups was obvious. The neck sized group was a 4 leaf clover with one outside of the hole. The other 2 groups weren't bad but nothing close to the neck sized group, even though just a little over 1", those 20 caliber holes are pretty tiny. By far the best group this gun has shot ever. Looking forward to trying this at 300 yards... |
