Well don't go deer hunting with a magnetospeed. Point of impact is of little use getting your correct velocity. So remove it before sighting in
Explanation anyone?

Yes it can. I always find my accuracy loads first and then use it so it makes little difference to me.
Yeah, probably a good idea to remove it before hunting. lol
That's my plan, now that I've been educated from ya'll here on this forum. Thanks much.

Funny story; I had said this many times while doing velocity checks of a load with the magneto speed attached. Not only does it change POI, but with some, if not all, my lighter barrels it tightens up the groups! Acts like a barrel tuner. Some of the groups are tight enough that I "swear" I should hunt with it attached....lol....maybe just a tad awkward carrying it through alder swamps!

When I make 6.5-06 out of 25-06, I use my Dremel tool to grind away the 25 portion of the head stamp so I can keep them straight.
Ball powders need a magnum primer. Even more so with starting loads.
The primer photo shows flattened ones. Not a true pressure sign.
Hard bolt lift/extraction is.

Is that true even in warm temps?

Here's a user tip for the magnetospeed. Make sure the bayonet is tight every few shots. On my Proof Carbon barrel its so slick I have to check it on each shot. On my steel barrels it stays tight better. As with any chrony have a few test rounds to verify you have the device setup properly.

No experience with carbon barrel but another tip is to place the unused rubber spacer on the top of the barrel and wrap the strap around it also. With cartridges like my 6.5-06 it stays put and does not slip and no need to retighten. I do this with sporter and varmint weight. It works on blued, polished stainless & matte finished barrels.
I don't have any "magnums" so cannot say what they might do, but I do know it works 1000% better than the strap alone with smaller stuff.
Mysteries And Misconceptions Of The All-Important Primer
Magnum Primers: Use As Directed
Most primer makers offer a standard and a Magnum primer in each size and application. The Magnum primer offers more power for challenging ignition scenarios. A large-capacity case, a heavily deterred propellant, or extremely cold weather (less than 20 degrees Fahrenheit) typically makes the Magnum primer desirable.
We tested loads at both maximum normal pressures and at the starting loads (some labs calculate start loads — we shot them). Standard primers caused no ignition issues at the max load but posted higher extreme variations in pressure and velocity in the lower pressure regimes of the start loads. In extreme cases, the start loads produced short delayed firings — probably in the range of 20 to 40 milliseconds but detectible to an experienced ballistician. Switching that propellant to a Magnum primer smoothed out the performance across the useful range of charge weights and completely eliminated the delays.

FYI you can by 6.5-06 brass made by Quality Cartridge.
I've read that the 6.5-06 brass is lacking in the quality department, but I have no personal experience to validate that
