r/longrange

15% off code at brownells helped me finally pull the trigger. Still plenty of things I need but I'll get there.

Recently had KS ARMS build me a 308 barrel for my AT-X. Here is a 10 round group with Federal T308T 168 GR.

Factory 108 ELD-M. 2638fps (hopefully speeds up a bit with more rounds down the pipe.

Super fun Team Sniper Match at Venado Springs Ranch outside of Bandera, TX. Elevation changes were brutal (1 hour 13 minutes in zone 4-5) especially with a 45lb pack. Total distance somewhere between 4-6 miles.

We decided to run heavy bolt guns, which probably was not the best choice, but was still able to get 2nd place in the ruck time.

3rd place overall but happy with the amount of hits we had on target. The stages and par times were a little off which made clearing a stage almost impossible. There was only 1 team that cleared a single stage. Gas guns would have been the way to go for sure.

Just picked up this KRG Xray stock as a bday present to myself. Not the biggest fan of the red but it was on sale and this particular iteration has a fore end that has a QD socket.

Not really a long range setup but I typically shoot 500 meters or less so it’s good enough for government work.

Now I need to play with seating depth to see if I can get below the half inch mark. This is probably only possible since the bolt is on the left. /s

Anyone in here from the Texas panhandle? I’m working on the opportunity to help build a range out to a mile up here and if there’s any one in here that would want to help reach out

Found this at a local pawn shop. No box or paperwork with it. They are asking $1100. What would be a good price for this? It'll be going on an AI AE mkii. Any concerns on whether or not it's real?

This is my second long range rifle, but my first full set up for KO2 Lite... Cadex CDX-33 TAC in 300 Norma Mag. Currently developing a load with Hornady 250gr A-tips, H1000, and Lapua brass. Seeing really good promise so far. Just need a more heavy duty tripod now, and will probably stick 2ith Cadex again.

Had a case head separation at my last match. I learned my lesson and will be replacing my PRS brass more frequently.

It looks like I had some gas cutting into my chamber. I can just barely barely feel it with a pick, so it isn’t super deep, but it’s there. Is my barrel cooked in yalls opinion?

Finally built up and did some initial testing with a SOLGW SPR barrel (14.5”) after seeing Preston Moore’s review. I’m not a brand loyalist and have shot and tested Criterion, Geissele, WOA, Noveske, BRT, Triarc, etc. I just like shooting groups and seeing what different gear (and I) can do.

All groups are handloads I had laying around, none were specifically optimized for this barrel, no headspace measurements, no jump measurements or seating depth tests (which I don’t do for gas gun loads anyways).

The smallest group here is actually shot with my cheapest 28cpr reloads using cheaper RMR 75gr bullets, Ginex primers, PMC range pick up brass prepped on a progressive press (no chamfering or checking neck tension), and Midwest Powder MP-424-4 (which claims to be “like 2230” but absolutely is not like 2230, and seems much closer to N140 / Varget in terms of burn rate based on velocity and pressure curves I’m observing from gas tuning needed).

The group over 1MOA is definitely me pulling the left most shot (called before I saw the hit), and is a 0.82MOA 9-shot group otherwise.

I know some folks are pulling off <0.6MOA 10-shot groups from gas guns, but I’m pretty happy with these results (with my skills as a shooter). This is now the most accurate AR barrel I’ve personally tested.

Went to fire form some new unfired brass. I didn’t bother trickle charging the power like I usually do and just used a Lee powder measure (which is usually off by +\-0.7 grains) and used standard CCI 200 primers instead of BR-2.
Not a bad group for little effort put in the process.

I’m working to develop a 6.5cm load and I feel like I’m getting close but I wanted to gut check with the hivemind. In the center, I fired two test shots with factory ammo to make sure I was on paper. The top other circled groups are shots of 10 with ELD match 140g. Then there’s the spray. Two groups of 10 shots using similar charges but with Nosler RDF 140g bullets.

I’m interpreting this as I should do a bigger run of the bottom left group since that looks the best. And I should probably stop playing with the Noslers since my rifle doesn’t seem to like them. With the goal being to tighten up my groups and reduce SD and ES, am I on the right track here?

Shot my first ever gas gun match in open division (placed 7/10) (25/37 overall) this past weekend. Pretty fun stuff, lots to improve on but I held my own for learning my optic, DOPE, and never competing in this type of event.

Sent about 500 rounds of M118LR through the tube this weekend. No stoppages. Lubed once with CLP. Chewed through the moon dust with no problems. Sounded kind of nasty when the bolt would close. Surprisingly stayed within a minute all weekend. Pretty consistent at 1k, even though it would go transonic at 770m. Only change I think it needs is a new charging handle. The gas was getting to a little too much to the face. Also side note, dope with the M118LR matched my hand loads of 42.0gr of IMR4064. Very surprised with no adjustments. Take a guess where I was lol.
