6.5 Creedmoore

[Terry wickenheiser]

I run 140gr bullets H4350, Superformance, and 4831SC the 4831SC was actually the most accurate powder for me if I was shooting inside 600yds it would be my accuracy load it simply lacked the speed I was looking for to shoot 1000-1200yds.

I'm not having great success with H4350. What is your load data for 4831? Superformance? According to Hodgdon the two produce similar velocities.

45.0 grains of Superformance with 143 ELD-X and other 140's shoot good out of three 6.5 Creeds I have. A Tikka. A TC Encore 28 in. Hunter barrel are two. Hybrid 100 powder good also and about same velocity . I haven't had much luck with H4350 and IMR4350. Have RL17 and others to try.

I use 42.6 gr of H4350 with 140 ELD-M, BR4 primers and Lapua brass. Ruger Precision Rifle. I can consistently keep my SD around 4.5 - 5.5 (as low as 3.1 measured last year) and my muzzle speed measured with a MagnetoSpeed V3 averages around 2800FPS. My overall case length is at max of 2.825 inches.

7.215 inch group at 1,000 yds, score=49

5 shot group at 100 yds, the SD is 3.1 not 31

Nice group at 42.4 but the SD was double digits.

I have settled on the exact recipe (with 42.4 of H4350) Excellent results so far in my tikka superlite.

I'll try in my Tikka T3 Lite. I may have been too mild at 41.0 grs.

according to hodgdon website 41.8 is top for the 143 and when I hit 41.8 I had ejector marks and my bolt was sticky on my Browning x-bolt.

I had no pressure signs with 40.0 hrs. In the Tikka, Encore or TC Compass bolt action . I'll try up to 41.0 next.

I had really good luck with the 140 gr. Barnes Match Burner #30230 and H4350. It seemed to be really forgiving across a broad range of charges but seemed happiest between 39.5 and 41.0 in my Savage.

 

[WYO300RUM]

I've shot a lot of Barnes bullets for many years but never the match burners. Just TSX TTSX. MRX. LRX in 24. 6.5. 7mm 30 cal. and 45 cal.
The match burners a decent priced.

it seems like h4350, varget and RL16 are the most often used powders-- RL26 would be great if it could be found . seems most are shooting the 130-140 class bullets

I'm thinking of trying some 110 HH bullets, I checked with steve and he said they had luck with varget--anyone else load the light 110 HH bullets yet?

I know this is an older thread....I did load some 110HH with Varget. Started @ 37.5gr working up to 39gr
loading in .5gr increments
I got a 3/8" 3 shot group 100yds with 39.0gr
The biggest group was 3/4"
This was the first reloading I've done with this rifle/caliber
I would have kept moving up but only had 15 bullets.
Book says max load is 41.0gr
Can you really go up to 45gr ???
Seems like a big stretch

I settled in at 41.9gr of Varget with the 110 Hammers in Lapua brass. I believe I could only get about 42.7 in yhe case, but showed some pressure.

Did it show signs of pressure at 41.9 or 42.7
Have you choreographed the load.
41.9 should get right close to 3000fps maybe a tad faster
Thank you for the info

Got my notes out, I got pressure at 42.5 with Varget and 110 Hammers. Targets were all shot from 100 yards, Magnetospeed was used for velocities.
