2014年6月16日 · The other 7mm magnums all had pmaxes between about 60000 and 64000 so i used 62000. When i put everything and adjusted the burn rate to match your muzzle velocity Im getting a pmas of 61460 with 72 grs, so under that max pressure, 73 gr give 64498 which is over, but not by a lot, and 74 is showing 67698 so over pretty significantly (this was ...

2021年12月23日 · Is there any justifiable reason to have my 7mm Rem Mag rebarreled to 7 LRM when the 7-300 PRC seems easier to find components for, cheaper more better? The 7mm Rem Mag has had both barrels shoot sub 1/2 at 3140 for the first one....and 3105 for the 2nd...but I have a feeling this summer will be...

I went back and read 20+ threads on 7mm SAUM so I have a decent idea what that cartridge is about, but it's a little harder to find info on the 7mm LRM. The pros of the LRM seem to be: 1) Increased case capacity for eventual release of 195 Hybrids. 2) …

2022年10月26日 · That 300 win mag is a much better elk rifle than the 7. Do the math. the 220 at 2950 or the 180 at 2950. I know what one I would take. I have seen how 7's work on elk over and over. Nothing wrong with a 7mm but the big 30's and 338's will kill elk quicker and I have been there for the taking of over 300 elk

2018年5月13日 · The 7 LRM is basically a 7mm-375 Ruger with the shoulder set back to give it a longer neck. It's a pretty good design actually. Problem is Hornady brass is the pain in the ass on 375 Ruger parent widlcats. I have a 338-375 Ruger.

2013年6月10日 · Mine is a BAT non-designated action, 7mm LRM (Long Range Magnum), 1-8 twist Krieger W/Gunwerks brake, Jewel trigger, Eric Wallace Benchrest stock, 20 MOA base, Burris Signature Zee Rings (added 20 MOA with inserts), Sightron S-III 6-24 with MOA reticle. Gunwerks factory ammo (180 Berger Hybrid). It weighs around 16 pounds.

2006年4月28日 · 7LRM is my favorite 7mm magnum. The brass is just fine. I have one set which I turned and necked down to 6.5 for my 6.5LRM and I have 10 firings on that set. Still shooting fantastic. I have about 6 firings on a set of 7mm stock variety and it's still going strong. However I run things at sane pressures.

2014年8月4日 · I got my brass from gunwerks, no issues at all. You can also form it from 375 ruger cases. Hornady makes the lrm brass for gunwerks. The problem with the 7-300 wm is the short neck. Ok if you know exactly what bullet you want to shoot. I specd my LRM reamer so all the 180s will work and the 195 hybrid should be above the donut as well when it ...

2012年10月3日 · New build in the works! Going with the 7mm LRM, Anyone shooting this round? Performance? This build started out as a 7mm Rem Mag but liked the idea of the non belted case, 30 deg sholder and the longer neck. Blueprinted Remington 700 LA .705" Bore PTG 1 piece bolt .704" dia Shilen #5 SS...
