usmc1974 Posted October 25, 2014 Share Posted October 25, 2014 is the built on a ar15 lower or the AR 10? What mags do you use. Thanks B Link to comment Share on other sites More sharing options...
Graham Smith Posted October 25, 2014 Share Posted October 25, 2014 AR15 - it uses its own mags. Link to comment Share on other sites More sharing options...
shootsforfun Posted October 25, 2014 Share Posted October 25, 2014 I did find a place that just sells the followers I can't remember the site. But I have a Grendel and shoot it all the time. It's a fun shooter Link to comment Share on other sites More sharing options...
Tom Freeman Posted October 25, 2014 Share Posted October 25, 2014 I have a 6 Grendel and am very happy. I use PRI 6.8 SPC mags. Link to comment Share on other sites More sharing options...
TonytheTiger Posted October 25, 2014 Share Posted October 25, 2014 Alexander Arms should have all the mags you could need. I think they're made by C-products, IIRC. Link to comment Share on other sites More sharing options...
Bill Schwab Posted October 26, 2014 Share Posted October 26, 2014 AA's new Grendel mags are made by E-Lander of Israel. Link to comment Share on other sites More sharing options...
TonytheTiger Posted October 26, 2014 Share Posted October 26, 2014 You are correct, at least my shooting times magazine agrees with you. And I think it was ASC not C-products previously. Link to comment Share on other sites More sharing options...
Sterling White Posted October 26, 2014 Share Posted October 26, 2014 I've been testing the 6.5 for a while and really enjoy the round. Here's the latest results for several different rounds from last week: Link to comment Share on other sites More sharing options...
TonytheTiger Posted October 27, 2014 Share Posted October 27, 2014 Oooh I love me some graphs! I wasn't aware hornady had a 100gr 6.5 A max. Learn something everyday. Now a wind drift chart would really complete my day, though I think the 123gr A max is the only way the 6.5 can hang with a heavy .30 in the wind. And are you using the same barrel length for this comparison? I ask because it would seem the 175gr SMK load was coming out of a shorter tube.

Sterling White Posted October 27, 2014 Share Posted October 27, 2014 556 was a 14.5; 762 was a 14.5; 6.5 was a 18.5; JP rifles; Tac powder in all. Link to comment Share on other sites More sharing options...
wgj3 Posted October 27, 2014 Share Posted October 27, 2014 Very awesome graph indeed! I love seeing real world results versus silly-long test barrel data. Link to comment Share on other sites More sharing options...
Graham Smith Posted October 27, 2014 Share Posted October 27, 2014 ... though I think the 123gr A max is the only way the 6.5 can hang with a heavy .30 in the wind. Actually, Lapua makes a 123gr boat tail that has a higher BC than the A-Max. Link to comment Share on other sites More sharing options...
TonytheTiger Posted October 27, 2014 Share Posted October 27, 2014 You are correct, I guess I was just thinking hornady products. Probably because they're factory ammo is a lot cheaper than the AA Scenar loads. I think I recently saw a 130gr factory match load somewhere too, don't remember the details though.

Sterling White Posted October 27, 2014 Share Posted October 27, 2014 Muzzle velocities were based on 10 shots to calculate an average. One of my goals has been to set up 2 systems that shoot about the same for 3g competitions, ie., 556/762. And another goal has been to rock the long-range targets at Ironman with the Grendel. This goal has been a challenge and has not been met. For various reasons I haven't been able to put that one together. Link to comment Share on other sites More sharing options...

I haven't got my rifle setup yet so I've got no load data to compare. On paper, the Lapua 123gr beats the Hornady 123gr but I'm not sure that it beats it enough to make up for the cost differential. Distance and wind are going to be more important than drop. Link to comment Share on other sites More sharing options...
JayDee Posted October 27, 2014 Share Posted October 27, 2014 I've had a 6.5 Grendel for the past year or so. AA Overwatch Upper with 24" barrel & AR15 lower. The Grendel mags I have are made by AR Stoner and came from Midway. I've shot some of the Precision Firearms 123 grain Scenar as well as Hornady 123 grain SST. Both grouped sub-moa from my rifle, and I'm just an average long range shooter. It's an excellent round and let's AR15 owners experiment with 6.5mm without investing in a whole new rifle.

TonytheTiger Posted October 27, 2014 Share Posted October 27, 2014 Sterling, any chance you could elaborate some more on your Grendel for 3g troubles? Reason I ask is my brother has a 6.5G on the way from JP and I'm hoping I ccan convince him to dabble in 3g or more likely PRS type matches so his high dollar rifle actually sees some use.

Distance and wind are going to be more important than drop. .1 - .2 mils better to me isn't worth the 60% or so increase in cost. The factory Hornady Amax is a real gem, good accuracy, good velocity and a great value you can find them on sale which makes them cheaper than you could make yourself if using new brass.

TonytheTiger Posted October 27, 2014 Share Posted October 27, 2014 My thoughts exactly Brian. Whenever my 6.5 upper happens I plan on running 123 Amax ammo exclusively. Link to comment Share on other sites More sharing options...
Sterling White Posted October 27, 2014 Share Posted October 27, 2014 (edited) Would like to preface this by saying that I reload and rarely purchase factory. Been like that since I was 12 in my grandpa's shop. In prep for the Ironman 2011 I got the items needed for reloading the 6.5G - bullets, dies, etc... In short order was at the range testing it and the first issue that I had to solve was magazine problems. The problem wasn't the actual magazine but the OAL of the rounds. I had followed recommendation that I had read from others and the rounds were a frogs hair too long and dragging in the mag so I shortened them. Next issue was some brass worked and some didn't. This gremlin liked to have driven me knutz. So I went back to the books, read up on case dimensions, and found that some of the cases had an OAL that was out of spec. I purchased a trimmer that sized off of the neck and solved another issue - now all cases were sized, trimmed, and with a little inside chamfering ready for reloading. Finally after several months of frustration and problem solving I worked through the issues and focussed on reloading. I loaded 108's and 123's for a short period of time however didn't have my dopes properly mapped when I got to Parma. The weather, altitude, and conditions were a lot different - I wasn't ready and hit 50% of long-range. So I go home and forget about the rifle and it sits. Before long its time to get ready for the Ironman and I didn't put the time in so being behind the 8-ball I worked on loading and practicing three maybe four times before 2012 match. This time I managed to rock 80% of the lr targets but timed out on the stage - not a good thing. It wasn't the guns fault or that of reloading errors as I had blundered earlier on some sg slugs that put me behind. It was somewhere in 2013 that I switched to 100 AMAX's. Opted for a little more speed instead of BC. This past year and again this year at Ironman the winds were terrible when it was my time to go on the stage. Not feeling confident calling wind I decided to go with my stage time and not try to create a greater overall time by engaging long-range targets. A roll of the dice. The lessons learned so far with the 6.5G include: you need to spend some time in good shell prep and trimming manage the OAL for magazines so they function test loads with a chrono enter the data into a good on-the-fly ballistic calculator like strelok pro keep notes about conditions, etc... when you do practice and put in some quality practice time at long distances (400 - 1000 yds) A 100-300 range isn't going to cut it when it calls on hitting a target at 650+/- Hats off to the PRS guys/gals. It's a fraternity all to their own. Edited October 28, 2014 by Sterling White Link to comment Share on other sites More sharing options...
TonytheTiger Posted October 27, 2014 Share Posted October 27, 2014 That's quite the tale of woe. Hopefully anyone attempting the same thing took notes. Anyone see that AA had the long awaited Wolf ammo? I'm sure it's not accurate enough for what most Grendel people intend to do but it could really help the cartridge catch on. Ammo cost is what I theorize is keeping the average gun guys away from things like the Grendel or 6.8. Link to comment Share on other sites More sharing options...
Graham Smith Posted October 27, 2014 Share Posted October 27, 2014 Sterling hit the mark on one very important point. Wind resistance is one of the most important factors. You have to know your ballistics. Don't get hung up on velocity and drop but ignore wind - it'll get you every time. Use a good ballistics program (JBM online is a good start) and study different loads. Then find what's best for the shooting you will be doing.

TonytheTiger Posted October 28, 2014 Share Posted October 28, 2014 Wind is the only reason I think I need a Grendel. I shot my 223 out to 880 a while back. Yes the drop was excessive but it was consistent and easy to dial for. I'll give you one guess what caused all the misses. Link to comment Share on other sites More sharing options...
