6.5x284 Load Advise

[kenacp]

Have a new bench rifle to play with. Not shooting any competition or hunting, just shooting to 800yds, steel and little groups. Would like to extend the barrel life as much as practical. Have 120's, 130's and 140's on hand. Seems H4831sc,H4350 is mentioned the most. Won't run it hot. What powder should I try first?
Thanks

Bullet Blowup 140 gr Mid and Michelle spent much of the holidays loading the 950 rounds shot during this test. The ammo was loaded in Lapua cases with 49.5 gr of H4350. Very HOT load when checking Hodgdon Data?

Heavier jackets increase pressure & problems.

I use H4831 and 4831 SC both with great accuracy and low pressure signs. I shoot only 142 Sierra MK and 140 BTSP for hunting. I am getting 3100fps out of the MK in my 30" Benchmark barrel and can lift the bolt with one finger. I shoot the same load out of my Savage 110 with a takeoff 24"factory barrel I bought on a board for $75 to my door. I tried the same load I shot in the long barrel and it loved it, only thing I changes is the 140gr Sierra game King BTSP and it shoots a 3 shot group into .400 or smaller with ease. Have taken several deer with it here in KY, including a 12 pt at close to 300yds head on last year. Center punched him in the chest, and made a 7" long and 2" wide exit hole out the left rib cage.

Hodgdon has data for "6.5-284 Norma"
and "6.5-284"

AI Overview


There is no practical difference between "6.5-284 Norma" and "6.5-284"
because "Norma" refers to the standardized, CIP-approved version of the cartridge, while "6.5-284" often refers to the same standard or the original wildcat version which has variations in its specifications, particularly regarding chamber throat and overall cartridge length. In essence, when referring to the standardized version, both terms are interchangeable, but "6.5-284 Norma" is the official and more precise name.

H-1000 with the 140's. Good velocity and great barrel life. Since I dont know your set up start at 50gr and work up. Depending on your lot you will probably find a node around 53gr and 54 to 55gr. 55gr will be getting around max or warm again depending on your lot of H-1000.

4350 and 140vld

H1000 is a lower temp, slower burning powder. Will give u the velocity with longer bbl life shooting 140 gr. bullets.

142 SMK’s and about 55 grains of N165.

Thanks for all the replys. Now to find some powder!

H1000 and Retumbo are my go to powders. You will be surprised with the accuracy and velocity you will be able to get.

I have 2 6.5/.284 handguns. Started out with WW760, but found out later that Hybrid V-100 gave about 150 fps more velocity. I use primarily 130 Accubonds & 125 Nos. Partitions. Killed about 18 deer from 500 to 565 yds., #2 handgun Cape kudu at 201, another Cape kudu at 365, plus hundreds of WV deer, and a good many more African animals and western game. Never had problems with Hybrid. Great accuracy.
Shot out 1 barrel after 2200 rounds. Working with a Douglas barrel now. Still great accuracy.

When I started shooting registered IBS 1K matches, the 6.5-284 was the new kid on the block, so I jumped on the bandwagon. My 1st barrel I was too focused chasing ES, & burnt up a third of my barrel life. I finally said enough, & just ordered 6 eight pounders of H-4831-SC. Every barrel after that was shot with that powder till I moved onto the Dasher.

Here is a 400 yard target testing loads in a new Heavy Gun barrel with 4831-SC and Sierras:

VV N-160 and N-165 are among the coolest burning powders suitable for your case capacity, and they may noticeably extend your barrel's accuracy life. I use N-160 in a 7-6.5 PRC (N-165, too, but N-160 shoots a little tighter in the current barrel) F Class rifle and the last barrel was still shooting acceptable match-level precision at ~2,000 rounds when I pulled it off. Its steady diet was N-160.

I load N-165 in a 7mm Walker and have had similar results.

If it won't shoot with 4831sc and 140 Bergers there is something else wrong...I read that in an old magazine
