He did a video on primers available in the US, and one thing of much interest was that the standard old lowly-regarded Winchester Large Riflr WLR primers had a hotter, longer flame than many big name LR magnum primers.
Not as hot as the big names that are essential in the RUMs, 300-378 and 338-378 Weatherbys and the 338 Lapua like Fed 215 magnums etc, but apparently, very close.
The Win LRM's are hotter !!!!
I used to watch a few of the old gunsmiths vids, but haven't seen any for a while now; I almost clicked on him the other week, but didn't. It was about a hunt, so he must still be doing it.
He did seem to build some good rifles, then loaded to get the best from them.
Also staunchly pushed the "use a projectile designed for hunting" on game.
It had me wondering about boat tails and stuff, as they could let the jacket separate more easily, when you think about it.
I must have tried about 6 different primer brands during the great primer shortage.
Just fear as I was buying a box of CCI every gun shop visit during the lead-up years.
Those #34s were the only real change for my loads, and only that Swede 2213sc load really.
It shot about an inch higher at 100m and got close to 100fps more velocity.
Still do them to take that advantage.
It's funny, but the other 6.5 in Gaylord, shooting 140 target pills, didn't show much change regarding where the group hit on the 500m big plate. That is just your std 41gr of 09, like most blokes' load.
Sort of shows a primer can make a difference, but only sometimes: a longer case loaded with more, and slower powder.
Sort of makes sense to me, and makes me not jump away from magnum primers for their recommended uses.
Just my view, and other stuff sure does work as well.
Sadly, primers don't cost 7c anymore.
