6.5x284 loads RL19,Norma MRP or IMR7977

29 80 ft./s
Very nice. Beautiful rifle as well. Mine is a full weight steel barrel, McMillan(A5) stock set up. Around 13 lbs. Building a carbon wrapped lightweight version, should come in around 8lbs total. Hope it shoots as good as yours does. No experience with the carbons. Probably will be the Bartlein carbon barrel.
 
I was given plenty of info on reloader 26, Retumbo and H1000 but have not been able to connect on any in SE Minnesota. I'm will be using 140 vld's and have 129gr long range accubonds. I have been using rl19 in my 7wsm with really good results. Anyone in the 6.5 using these combos? I have 2 rifles to play with 1-26" light contour 1-8" and 1-24" 1-8" with a Heavy contour. I'm open to other powders to try as well. It has just been tough to find much around at the stores.
The data for H1000 should be very close for IMR7977. I have shot a lot of both in 2 7mm LRMs and my new 6.5 PRC. The 7977 seems to always need a small amount more charge weight to match H1000. Usually its a grain or less. Start with the low end of H1000. The IMR site shows 49gr H1000 as MIN for 140s. They also list data for several other powders I've used a lot, namely H4350, IMR4350, and IMR4451. Most of these powders should be available some place.
 
H4831sc is the most accurate powder I've ever used. Not the fastest but very accurate. 2950 seems to be the best accuracy in my 29" barrel. Ran it all the way up to 3150 but accuracy dropped off to .75. Currently .2 is my accuracy in 5-7 shot strings. Some 3 shot strings are less than .1.
Another vote for H4831sc. I'm getting 2920 out of a 26" barrel with Hornady 147s, and 3 shot groups regularly under 0.3". Again, not the fastest, but it's accurate and temp stable.
