This a common sense warning for cast bullet rifle handloaders.
It comes under the heading: words to the wise.
Gas checks WILL dislodge from the base of bullets. In bottleneck
cartridges, this may result in an obstruction in the case and SERIOUS rise in pressure.
(Read damage to rifle and owner.)
EXCEPTIONS: straight wall cases. I also trust a long neck more, like the 30-40 Krag.
Once the bullet goes into the case and is seated, you no longer have control
over that bullet base gas check.
Iuse lots of lead bullets in a Sharps and a 1885 Winchester Hi Wall made in 1887. No gas check needed.
I no longer use gas checks in bottle neck cartridge rifles-good luck to those who do. For 270, 348 WCF, 338-06, 35 Whelen & 375-its
jacketed bullets or they stay in the safe with cleaned & oiled bores. I will save money some other way than buying gas checks/GC bullets.
