What loads are y’all running in 6.5 Grendel’s out to 1000 yards. Mine is a 20 inch 1-8 Odin Works upper. I understand each load will have to be worked up in my rifle,I’m just looking for suggestions I can work on bullet choice, powder, etc. Thanks

No 1,000 yd ranges out here Eastern Maryland But to me I always want to have loads that have the capability to get to 1,000 yds above transonic speed at sea level. Transonic is important because bullet generally do not react well in this range which is approx 1,230 fps at sea level. You can load a 107 SMK and it will not get you there. At a muzzle velocity of 2,693 FPS it get you to 920 yds transonic and and supersonic to 1,020 . So just barely there.

The real pills that get you to 1,000 yds are in the 123 to 130 range. You may even consider the 140 RDF but the drop is up there. At a slow start (2,389 FPS muzzle) at 1,000 yds with a 200 yds zero 10.7 mills drop. Transonic at 1,080 yds. Supersonic to 1,225 yds at sea level. In comparison the 130 RDF with a starting velocity of 2,498 fps at seal level it gets you to 1,095 yds transonic and 1,225 supersonic. 10.3 mils drop

For the 123 gr bullets if you use Lapua Scenar approximate velocity is 2,563 fps out of my 20” barrel. For the 123 Scenar it goes transonic at 985 yds and supersonic to 1,100 yds. These numbers are based upon my barrel a BHW 264 LBC. To get these velocities they are warm loads. It will end up beating your brass pretty bad. 2 to 3 leadings before primmer pockets start loosening up. Powders used are Power Pro Varmint , CFE 223, and AR comp.

For me it just became problematic pushing the t so hard. So I just ordered a 24” BHW 264 LBC barrel this will give me another 100 to 120 fps which will push the transonic out 50 yds with 107 gr MK load and about 90 plus more yds with the 140’s. Which give me a little more room for backing down my loads. Those are the powder and loads also the Grendel like CCI450 primers. You can find load data for all these powders and bullets on 6.5 Grendel forum. For me while the 140, can get you there ar relatively mild starting velocities I leave the 140’s for the Grendel’s big brother the 260 Rem or 6.5 Creedmoor in an AR1O.

Thank you for the advice, I will go to the local gun shop tomorrow and see if he has any 123 scenars or 130 RFDÂ’s and start there then. I have CFE223 and 8208XBR on hand IÂ’ll try both and report back with Chrono numbers and groups hopefully out to 1000. Thanks again

Well I’m reporting back. My local shot had the 130 RFD’s so I decided to give them a go. I tried the with 8208xbr yesterday starting with 25.5grs and working up to 27grs. The hotter the load got the tighter the groups where. My 5 shot 100 yard group was .577 moa with a SD of 8 and a ES of 17 with a average speed of 2347FPS. The RFD’s did disappoint at 1000 with a 8 1/2 inch 5 shot group on the 16x18 plate. End load was 27 gr of 8208@ 2.261 coal in hornady brass with BR-4’s thank for your help. I want to post pics but for some reason I always get a failure to upload message it’s driving me nuts.

First off sounds like awesome shooting to me 1/2” moa out to a thousand yards is pretty sick for your first run out. I would be ecstatic. CFE 223 and Power Pro Varmit should get you about 100 to 120 fps more, but accuracy as we know can vary from barrel to barrel and chambering ( Grendel II or 264 LBC. ) because you can load 130,s and even 140’s out to 2.300. Go to Hunting and Shooting with the Modern Sporting Rifle (AR-15/AR-10) and look up Grendel Reloading project. It’s a caloborative google sheet document give you loads from 90 gr to 140 gr with all kinds of bullets and bullets info.

Thanks again for your help, and let me know how the LBC does, I’ll post group pics if I can ever get this darn phone to do right . Lol,they’ll be more to come for sure Ive pretty much got my little homemade range like I want it; it’s a 1,600 yard long hay field with 10 or so gongs from 200 to 1300 at the moment, 100 yards from the back door, so I’m like a pig in mud.

Lucky you. Have a great day! I’ll let you know how the 24” 264 LBC does when I get it to the range. Great news today it shipped so I’ll get it beginning middle of the week. Put it together over the weekend and then I got to get a range day. But here in Annapolis MD I have to drive an hour to get to a two hundred yard range.

I've been playing with the 243LBC for a couple of years (bolt and AR) and have gotten to know Ritch pretty well, a little hint I was given was to get a Young Mfg. bolt as they will hold up a bit better to pressure. My 6.5 Grendel is just a pig gun, 18" barrel and I'm shooting the 130 Sierra GK and while not a LR bullet they are pretty dang evil out to 300. My 6.5 with the short barrel the Pro Power Varmint didn't give me the velocity I was hoping for so I've gone back to H4895 and having good luck..... pretty sure you fella's with the longer barrels should see some increase in velocity. All the guys I know that shoot the 6.5G are running either the 107SMK or Tipped version but our little match is only 500 meters and H4895 or 8208 with one fella still using up his jug of AA2520. Have fun and Id be interested in what you find out that works for ya.

Kirk thanks for your advice, That is what I bought mine for also we are over
run with pigs here in south Mississippi my first load for it was a 123 SST over
27.5grs of 8208 and they have worked very well on pigs and deer out to 250
or so, but IÂ’ve been shooting my bigger rifles a .300 WM and a 6.5 creedmoor
out to 1300 yards and a .224 Valkyrie 24 inch AR to 1200, and I just couldnt resist
the urge to take the little Grendel on out. The 123 SST does ok on steel
to 600 but after that there is some inconsistencies, the 130 RFD that was
recommended to me seems to have something going it shot dang good at 100
and was able to put all rounds on the plate at 1000. Think IÂ’m going to do
some more playing with that load to see if I can get more speed, but IÂ’m
at Noslers book max for 8208, May try CFE223.

Great [emoji106] insight from the world of realville guys. The Hunting and Shooting with the Modern Sporting Rifle (AR-15/AR-10) reloading project covers everything form 90 gr to 140 gr bullets and is a great baseline of load data. I’m interested to see the amount of velocity I can gain going from my 20” BHW 1-8 polygonal barrel to the BHW 24” 1-8 polygonal. I guessing 90 to 100 fps. I currently shoot 107 MK, 123 gr SST’s, 129 gr SST’s, 130 gr RDF’s. I let you know how it goes at the range

Long as your not seeing pressure signs I'd bump up the 8208 a couple tenths at a time until you find pressure then back off a touch. My load is for the 130's is a bit more than the book says but I've got no pressure and it's shooting wonderful, honestly I ended up several grains over what Hodgedon's lawyers said to print :) The H4895 gave me better velocity but the 8208 was more accurate.

As far as your speed I think you are dead on with your estimate, I have no experience
going from a 20 inch Grendel to a 24, but I have a 24 inch barrel Valkyrie
and a friend has a 18 inch Valkyrie and with the same 80AMAX load I’m
about 120 FPS faster. As far as going on up on the load of 8208 i fully
intend to do that think I’ll work up to about 27.6 in .2 increments until pressure
Or decreased accuracy give me a reason to stop.�� I’ll post back.
