[jesse71]

I am currently working up a Barnes 120grn TSX load using H1000,does anyone have any experiences or recipies for this projectile or projectiles of this weight?

Might be a bit slow for that bullet weight.

I was thinking of trying H4831 as next step.
In a perfect world I would be trying RL19 but this is rare in NZ.

I can get Vihtavouri powders but can't find any data for STW.

19 loads available in 7mm STW with bullet weight equal 120

Cheers Ridgerunner,

Has anyone loaded Barnes 120grn TSX?

 

[Tyler Kemp]

Why not try the 140 grain Berger? You can get it over 3500 fps and the BC will help it past a couple hundred yards.

Thanks for the information I didn't know Berger made a 140grn for the 7mm. I will investigate availabillity.

The reason I am trying a 120 Barnes load is I have found the Nosler 140 grn BT quite explosive on the Chamois we have in this country.
Nice neat hole on entry and a fist sized hole on exit. They tend not to run to far though.
I have had better results with the 140 Accubond but thought I would try the Barnes, (as they are quite often raved about) and go to a lighter bullet.

Using 87.6-87.8 grns H1000 (ADI AR2217) I have achieved groups of 18-20mm(3 shots) @ 100m using Remington brass,CCI 250 primers.

I have had keyhole groups with both the Noslers using the same but with 83.5grns of H1000.

I am yet to chrony these loads as I do not own one and usually load for most accurate load.

I have found I can get hold of RE22 and I looking at trying some of this over a chrony of a friend along with my existing loads.

Hard to beat the H-1000 in the STW, I run 140's to 3550 in my bansner UR-1 with 86 gr of it.

I know H1000 is great with bullets 160grn and above but alot of the reloading manuals quote other powders such as H4831,Reloader 19/22 etc with the lighter bullets.
Have you found H1000 the best across your loads or is another powder more suitable with the lighter bullets?

 

[Ridge Runner]

never shot anything lighter than 140's in mine. I tried re22, H4831, IMR 4831 and couldn't come close to matching the velocities I got from H-1000, the only other bullet I've shot in that rifle is the 160 accubond, running it with WC872. tried a few 140 original x-bullets but they didn't shoot well at all.

jesse71,
This combo to me is a total mis-match ( like Ellen DeGenerate getting married to her girlfriend). For a 7STW you should consider mabey a 160grain Accubond or a Berger168gr-180gr VLD and leave the 120gr copper foulers to the 7mm-08 crowd.

Cheers for all the input gentlemen.
I think I will stick with H1000 and the Accubonds.
Some chrony time is in order I feel.

 

[jasonprox700]

Accubonds or Scirrocos are great too.

 

[jesse71]

Thanks.
Scirrocos are a quite expensive down here and are not readily available.

Has anyone tried Noslers ETip?

I suspect they are just trying to compete with the copper club?
