1,000 yard load
« on: August 11, 2018, 12:03:24 PM »
Hello out there I'm checking to see if anyone has worked up a round for 1k benchrest that shoots well. I'm working up my brass now and plan to start with SMK 90s. I've got a 7 twr barrel and am hoping these stabilize ok.
Also any thoughts on chamber dimensions? Tight vs loose necks? Freebore? Any input would be very welcome

I have several hundred rounds on 1000 yard targets. Tried several projectile/ powder combos. Landed on 88 gr ELDs and Re-15. 25 grains at 2.300" (max that fits in my Grendel mags) I think I have the out of spec chamber. ELDs are jumping .020+ loaded at 2.3". 24" barrel btw. 7twist
Solid 1/2 moa load but I can only keep it a little under 1 moa at 1000 consistently. It has shot several smaller groups in the 3 to 4" range ( one 2.5")but 7-8" is more the norm

Just realized we were on the bolt gun page! Are you talking bolt action? If so FYI I'm shooting an AR

Yes I'm shooting bolt action. Have a R700 (tweaked action) with a Bartlein Heavy Palma 1:7 twr. The barrel's not chambered yet and I haven't decided on a barrel length.

I'd frame that 1/4 MOA at 1,000 yards target! Too bad you're having a tough time getting it to repeat. That's my goal - a repeatable 1/4 MOA at 1K yds. My problem is finding a 1,000 yd range where I can shoot paper, all the local ranges are metallic targets from 400 out to 1k.

If you get one doing repeatable .25 moa at 1K you will win a lot of matches! Please keep us in the loop as to how it's progressing. I, at first, didn't understand why anyone would want a Valkyrie in a bolt action with all the other options ( for eg. I've been shooting a 6.5x47 Lapua
for a year now and it is a really good round for paper and a hammer on game). But after nearly 1000 rounds through my AR Valkyrie ( I'm not really an AR kinda guy) I see the merits of this round in a bolt gun. My next project will be bolt action Valkyrie!
