DPMS .260 first 3 loads

[fmsniper]

wet and cold range day today.
My upper arrived in the mail I cleaned it, mounted a scope and headed to the range

loads
1. 140 grain Nosler accubond 5 shot group .464
2. 140 grain Berger VLD 5 shot 1.039
3. 130 Berger VLD 5 shot (only counted 4-called the 5th) .484
testing 100 yards
powder 4831 SC
all loads were 46 grains and COAL was to barely fit in the magazine
needless to say I am happy with the starting loads.

gun is DPMS 24 inch upper 1-8.5 twist, geissele trigger




still need to paint the upper to match

That was my first .260 Rem as well, a DPMS 24" LR-260. My current one is a custom build from GAP with a 22 Bartlein.

You definitely have a shooter if those are your first groups. Try the 140gr Barnes Match Burners too.

What's your brass look like?

 

[fmsniper]

brass look fine, no issues

 

[LRRPF52]

These are my very first groups with the 139gr Scenar and H4831:

 

[fmsniper]

will have to give some of them a try

I have a dpms lr260 that is still going through breakin about 60 rounds down the tube managed a.29 3 shot group but shoots under an inch if I do my part with federal premium 120 grain nosler ballistic tips. It's very hard to shoot well with the dpms crap triggers Good job on your groups keep it up.

 

[FALex]

you folks running the .260's, could you please post your barrel's length and velocities as well? Thanks!

 

[Cnewhouse48]

My dpms is 24" ss with target crown velocity is unknown for me I don't have a chronographer but according to federal I believe they state around 2900 out of the muzzel.

Is this for DPMS only?

I have an LMT MWS w/ 20" SS .260 barrel (1/9 twist) that shoots sub-MOA 5-shot groups.

120gr A-Max
37.1gr Varget
Remington #9 1/2 LR primers
Mixed once-fired .308 brass sized down.

Velocity is about 2840fps.

Problem here is that the gun won't cycle the gun completely. It will extract and eject, but won't pick up the next round or lock the bolt back on last round. Next time out, I'll try 37.5 gr.

I'll take a 1.5 MOA gun that is reliable over a sub-MOA jam-o-matic.

 

[Cnewhouse48]

I will agree with you THEBELLY on the reliable weapon so far I have had no problem with my dpms other than the trigger it seems to like the federal ammo as well I'm going to work on getting my press set up again soon so I can really play... Sounds like you need to ply with powder a little bit

140 gr Amax, Lapua brass, 45 gr. H4831 sc, Fed 210, same gun w/"wet" BCG. Great results. Needed to break mine in with well lubed BCG. No issues now.

 

[LRRPF52]

DPMS receivers/BCG, Bartlein 22" barrel done by GA Precision, 1/8.75" Rifling

123gr Scenar 2950fps
130gr VLD 2810fps
142gr SMK 2740fps

[Thebelly]

How many guys running are varget powder????????????

Not any more.

for 260 I use H4350 for the semi-autos and H1000 for the bolt gun.

Any load development updates?

Ryan

123 gr Nosler CC
41.0 gr H4350
Fed 210 Primer
LC LR 12 Brass necked down and then neck turned

this gives me 2695fps without the can and 2710 with the can.


ETA: the gun is an LMT MWS with a factory 20" stainless .260 barrel.
