[QUOTE="RH300UM, post: 472135, member: 12469"] I played hooky from work today. I loaded 33 rounds for my 284 Thor that Travis Redall built for me. With the ammo loaded as well as the truck I headed to the range 2 miles from my house. Load info is as follows.Norma brass, Berger 180 vld hunting bullets,Fed. 215 Gold Metal primers. US 869 powder. I started the loads at 97.5 gr. and worked up in tenth incriments ending at 98 gr. I loaded 5 rounds for each weight Except the 98 grain load I only loaded 4 rounds due to fire formed brass I had avialable to load. I cleaned the rifle barrel after every 2 shots as I am breaking in the barrel. Results are as follows: Group 1 1-3144, 2-3144?, 3-3180, 4-3187, 5-3154 avg.fps.3161.8 ES.43fps. Group size .558 Group 2 1-3154, 2-3190, 3-3167, 4-3163, 5-error avg. fps.3168.5 ES.36 fps. Group size .545 Group 3. 1-3161, 2-3189, 3-3165,4-3223,5-3208 avg.fps.3189.2 ES.62 fps. Group size .538. Group 4. 1-3153, 2-3134,3-3158,4-3164,5-3170 avg.fps.3155.8 ES.36fps. Group size .550 Group 5. 1-3203,2-3186,3-3195,4-3177,5-3205 avg.fps.3193.2 ES.28 fps. Group size .520 Group 6. 1-3181,2-3253,3-3215,4-3248 avg.fps.3224.25 ES.72 fps. Group size .540 I went back to the loading bench and loaded 4 more rounds at 98gr. and raced back to the range trying to beat the snow that was headed my way. The picture below is the result. I cleaned my rifle completely befor sending the last 4 rounds down range. Not cleaning every 2 shots this time. Here is my surprise. The same powder load as the last group of shots in the previous session. This group is as follows:1-3248,2-3253,3-3251,4-3242 avg.fps.3248. ES.11fps!! Group size .512!!! The group sizes I know can be me. But the avg. fps. and the ES. are what have me somewhat puzzled. Just the same I will continue with the 98gr. load and see if the results I got in the last shooting session today continue on. Thought I would share this for those interested.
