Just my two cents, At one time building a rifle I had some primer issues similar and thinking my bottom end loads were too hot already. It turned out the chamber is a hair long not NO GO long but not tight. When the FP hit the primer it would shove the case forward allowing the primer to back...

The +2 is going to give longer for gas’s pressure in the barrel to drop closer to designed operating pressure and timing of the unlocking of the bolt. IIrc most of the short mags have issues with breaking extractors. The biggest reason for this is too much pressure still holding the brass to...

Haven’t been able to get 250’s or any other magnum for that matter. I have used the 34 in 308, 300 WM, 25-06 300 WM has been with all powders I have tried. Ramshot hunter, 7828, h1000, h4350. I have had good results with it but I also haven’t loaded a pile of any load that I have liked, hoping...

This is similar to what I have seen before as well. It was my understanding that with the use of many all powders in nato an military cartridges in general that the cold ignition properties were the reasoning for magnum priming mix. Hot of the email wire as I typed this up! They state that the...

Cci 34 is considered a magnum primer by many and has done a fine job for me igniting the loads I use it for. I have nothing in writing from cci concerning it being a magnum but multiple sources list it as having magnum primer mixture. I do believe I will email them soon and find out from the...

Only “magnum” I have been able to find since I started cartridges that called for magnum. They certainly have gone up in price considerably since I started using them for 7.62’s

One more quick question concerning compressed loads 80.5 is coming up about to the shoulder in the case with these bullets. I have messed mostly with ball powders and done very little compressed loading. In those that have loaded this cartridge/ powder combo what would you consider highly...

As of yet no bullets have pushed from final seated position. My Barrel length=24” load data assumed barrel length= 24” Fire case capacity 92.4 x3, 92.5 x2 Load data assumed 82.3 Difference comes out to 0.6 CC My coal 3.362 Data speced 3.330 I’m going to try using a drop tube to see if I can...

Seeing as how the 80.5 gr numbers are what nosler show for their 77 gr numbers I’m going to see where the last half grain puts me. I also need to double check my numbers for case capacity and compare them to nosler data. There are no pressure signs as of yet. Primers are perfectly rounded...

Sorry, yes 300winmag

So I previously worked up a 300 win mag for load with ramshot hunter pushing 180 AB with Winchester brass and cci 34’s to 3050 on average with 70.5 gr. I know this powder is between 4350 and 4831 in burn rate. While developing that load it increased as expected with charge increases. Working...

I’m not sure if you got this sorted yet. Dealt with my 6.5 not cycling to lock back by contacting the manufacturer once I realized the “matched” gas block was blocking 0.040” of the port. It was a rifle length+2”. In my experience a 5.2 oz minimum buffer is needed in all large frame AR builds...

I just checked earlier this morning and none was available, thank you for this.

300 Win Mag. It popped out perfectly this morning. Will trim the excess this evening. Need to see if I can find some longer screws local. Mag well frame may need to be filed. The front action screw overlaps the hole in the aluminum bedding block but the action hole is lined up perfectly in the...

Bedded with devcon today. Waiting for it to cure will take it out tomorrow. Hopefully it comes out nice and easy. I set it at 030 clearance each side of barrel, might take it out to .040”. Will need longer action screws with the new stock and real bottom metal. Shaping up to be around 10.5#...
