[QUOTE="Moose47, post: 2713963, member: 116196"] Finally got some intial data for some RL 26 / 190CX vs 190LRX I loaded 79gr of RL26, Fed215 primers with both loads .100 of the lands. 190CX @3118, 3885 ft,lb 190CX @3134, 3925 ft,lb 190CX @3114, 3875 ft,lb 190LRX@3173, 4023 ft,lb 190LRX@3138, 3935 ft,lb 190LRX@3190, 4066 ft,lb, Using Shooters Calculators.com the following data was developed: For the 190CX with an average velocity of 3120FPS, zeroed at 300yards sighted at 3.11 inches at 100yards energy would be 3717/ 2968 FPS 300 yards would be 3031 energy/ 2680FPS. At 400 yards energy2728/2543 FPS/ bullet drop - 8.54 For the 190LRX with an average velocity of 3150 FPS zeroed at 300 yards sighted at 3.06 inches at 100 yards energy would be 3766/ 2988 FPS 300 yards would be 3033 energy/ 2681 FPS. At 400 yards energy 2712/ 2535FPS/ bullet drop 8.53 What's interesting is that even though the LRX showed an increased average velocity both bullets show almost identical performance at the 400 yard range. Bullet drop -8.54 vs -8.53// energy 2728 vs 2712// FPS 2543 vs 2535. Accuracy for both was around 1.25 with the CX being a little better. Overall I would say using the RL 26 powder with either of these bullets would be an awesome hunting load. I think some would say this data would be what you expect from a 300 Weatherby. Lastly all of this comes from the Ballistic Coefficients of these high performance copper bullets IE CX @ .575// LRX @.541. [/QUOTE]
