Home Forums Hunting & Shooting Express Rifles and Big Bores Only 375h&h load workup on Hornady and Barnes 270 grainers

Just finished Friday on a load workup for the Hornady 270 grain interlock, and the Barnes 270 grain TSXFB.
Both turned out very satisfactory, but the journey was really interesting.
The Hornady's max on RL15 is 74.3 grains, (The Hornady data max) and I started at 72 grains and worked up to 74.3 (72, 73, 74.3). All three loads shot to the same point of impact, and all three grouped very, very tightly. Velocity was 2640 at the low, and 2705 average at the high.
Here was the last group of Hornady (4-shot group at 100yds)

The Barnes finished well, with a tight group of 4 at 75 grains of RL15 and an average of 2710 fps.... but, my loads at 72, 73, and 74 grains prior to the 75 was very scattered and not acceptable. Here is the last group at 75 grains on the Barnes:

I know the Barnes is superior on penetration and weight-retention, but I will be loading and shooting the Hornady on it's consistency and accuracy in my rifle... it won the day.
(rifle is a classic model 70 crf)
cheers.
