6.5x47 lapua

Anyone who says they are fast enough to hear a delayed ignition in a ceneterfire cartridge do to small rifle primer VS large rifle primer is completely full of BS lol

That or they really need to get there eyes and ears checked by a professional.

Stop by in the middle of January and we can end this real fast... But only if you're prepared to put $1,000 bucks on it.

So what powder are you using that a magnum small rifle CCI primer is having trouble with? Have you tried a different primer? A different powder? What's the problem load in January?

The small primer VS the large primer can someone explain the difference to accuracy in this 6.5x47L caliber? Prime pocket hole L vs S?
The delayed ignition can be felt in a good BR rifle with a sensitive trigger set light at say 1oz.
You may not be able to notice the hang fire if you are chocking the hell out the rifle stock.
When I shot the 6x47L I found the VV560N to be THE powder.

Could be some of us are just more perceptive than others or perhaps hangfires don't happen to every rifle... but I doubt that. But ya... I could not help but notice the hang fires. No super power here.

To you defender of the "all is well" with small primers school...

Have you actually chronographed your velocities in cold weather and compared to chronograph results in hot weather?

Or, have you just not noticed the problem because you are not looking close enough? I can answer this one for you... Ya... you are not doing your homework before tapping the keys to defend what you don't want to believe.

My guess is that you shoot mostly at 100 yards and would not notice the velocity spread manifest in terms of vertical spread at long range.

I haven’t chronographed my loads in the winter but I shot small primer brass in our winter f class League and have not noticed and big vertical spread. 300m,500m and 900yrds. I’m pretty sure there are lots of others that shoot the winter league with small primer as well.

I'm done here... believe it... don't believe it... I don't care.
I cant help you solve a problem if you don't what to know that you have a problem.

 

[backdoorsally]

Pretty sure this problem as all in your head

 

[shockman]

Wow!!!

I’ve been running my 6.5 Creedmoor with Lapua small primer. Shot it all last winter in some pretty cool weather with no noticeable ignition problems. Running a fairly full case of H4350. Are some powders more sensitive to this?

In my 6.5cm Lapua brass, small rifle primer (CCI 400) I was getting hangfires with W760 and CFE223. Switching to large rifle primer Alpha brass solved this. Even with the CCI 450 magnum primer I was getting hangfires and erratic velocity with the ball powders. Temps were around 10c, so it was not cold

CCI450 with H4350, RL16 or any other extruded powder, even RL26, no issues at all

Ball powders have always required the hottest of primers, regardless of size. And they are the dirtiest powders as well. They meter out nicely though.

All my shooting is done from 500 to 910 yds on steel. Haven’t noticed a difference in vertical from shooting in fall at say 15C or -20C in January. CCI 450 and H4350 with a 130 Berger hunting. 26” Broughton built by RBros running at 2950 fps. Defiance action.
