Hello,
I have acquired a Gewehr 88 in 7.92x57J.
It takes 0.318" bullets.
Folks keep urging me to try cast bullets in it. I've resisted this because I like to use what a particular firearm was designed for -- in this case, jacketed. (If I were shooting .45-70, I doubt it would see anything but cast!).
Now, realistically, the 0.318" bullets come at a custom price and I'd like to shoot it more.
I've zeroed it for a 150 grain spitzer at about 2500fps. This is not as easy to zero as my Mosin-Nagant as I've not made up a finely adjustable sight for it, but used a tall front sight from Brownell's.
That means a cast load moving fairly fast to hit the same point of aim -- or close to it, at least on elevation.
That means gas checks.
I know nothing about gas checks.
I cast for the .45acp and for my muzzleloaders. I use my own dry lube on the .45 bullets and nothing on the lead round balls (they are patched).
This means I tend to like the Lee tumble lube bullets when dealing with conicals, and I do not resize. They drop out the right size most times and the ones that don't just go back into the pot.
So, this all relates to gas checks for this reason: I don't know how to put them on! Everything I read says to put them on with a lubrisizer.
How fast can I push a 150 to 170 grain gas-checked bullet?
I'd like to make this come together, but I don't want to tap in the old sight (put up in storage should I ever sell this thing) each time I want to change from jacketed to lead bullets!
Bottom line: How fast can I push a gas-checked bullet, and do I need special equipment to put the gas checks on?
Thanks,
Josh
