I'd like to agree with you as I find using BR2 CCI (non-magnum) primers for my 300 win-mag yields better (lower) MV ES without any issues. However, using same (BR2...) on my 338 LM causes over 30% misfires. When I open up misfired cartridges, the powder looks singed, but intact. The powder is...

Jasent, awesome group. What rifle ?

That's correct. I spoke to them at a show. The "inventor" was there and seems to know what he's talking about (FWIW I have a degree in optics engineering), nice guy too.

Anyone familiar with the Quigley-Ford DFP dual focal plane scope ? It superimposes a ballistic FFP reticle with a regular cross-hair SFP reticle. https://quigleyford.com/product/5-20x50-dual-focal-plane-scope/

How is Idaho for non-residents ?

Quigley Ford makes a DFP (dual focal plane, FFP + SFP) by (optically) superimposing a ballistic FFP reticle and a regular (crosshair) SFP reticle. The SFP reticle is (obviously) invariable in size so you can see it clearly at minimum magnification and low lighting. The FFP works for any...

I'm up to 4-5th reload on Lapua, Selliers&Bellot and PPU (probably ~2500 loads altogether) with no signs of pocket loosening, ... etc I anneal every time. Hornady cases on the other hand split on me twice - once at the neck at 2nd firing (!!!) and once at the shoulder at 3rd firing. Fooled...

Congratulations !!! You got every reason to be proud !!!

Looking forward to that and Happy New Year, everybody.

But I'm off topic. Welcome to the forum (from California's Bay Area), great place, people, knowledge.

Whereabout the bay area ? I'm from Menlo Park. Knowing the people from here I'm guessing you and I area the only silly-valley people on this forum :)

Awesome shooting. What rifle and what optic if you don't mind sharing ?

In a slightly different vein: I experimented with using non-magnum large rifle CCI primers (clearly not what 300 WinMag calls for) and found that I can systematically shave ~10 fps off the MV ES (presumably because of the smaller disturbance they cause) and never had any misfires (over 30-50...

Below is the measurement data graph. MV was measured with a labradar. Blue dots/lines are for measured data. The confidence intervals correspond to the extreme spread in measurement for both MV and temp. I measured the temp with a thermocouple directly on the brass before chambering it. I kept...

In a nutshell, I wanted to see how muzzle velocity is affected by powder temperature for Vihtavuori N565 powder. I found that MV velocity goes up about 0.33 FPS per degree F for a 300 Win Mag round containing 75.2 G of powder with a 168 G TTSX bullet, CCI large magnum #250 primer, Lapua brass...
