45-70 govt, 405g, gas check or not?

Just bought a GG in 45-70 and grabbed some cast 405g bullets to try. It's my first attempt at using cast bullets. I just realized after looking at the Bullet Barn web site that the same bullet is available with a gas check, but mine don't have it. Wondering if I should return them and try and get the one with the gas check. I want to use them as a all-rounder, bear defence and maybe hunting, all with IMR 3031. Searching shows that most people don't get them going that fast anyway and I understand that 1500fps is where you start to need the check. What are most people shooting out there? checked or unchecked? thanks

Both, gc and flat base. I think your 1500 fps may be about right for needing gc, but Ben Hunchak could tell you for sure.
On loading the cast bullet, the case mouth has to be expanded to start the bullet. To extend case life, this expansion must be very small. I open mine up just enough that by running my fingers over the case, I can tell there is a slight rise at the mouth.
Gas check bullets are easier to load, as they tend to squeese in, whereas a flat base bullet will want to shave off lead, and may require more expansion of the case.

bell your cases slightly to reduce the shavings, use a punch to cut .459 pieces of wax milk cartons and stick ti the bottom of the bullet with lube/soft wax. the cost to return would be more than it was worth

Do not stick a grease or lube on the bottom of your bullet. You want to make a grease cookie if going that route. Sticking a wad onto the bottom of your bullet will cause you problems.
The type of rifle you are using will dictate your use of a gas check.Also there a horror stories out there about improper use of gas checks sticking in the bore

Any commercially made 45/70 rifle can shoot either properly applied gas checked or non gaschecked cast bullets.
Your quest for accuracy and/ or velocity usually governs which route you pursue for your particular hunting rifle.

Mr. Teenahlake
I have never heard of anyone claiming that "sticking "or glueing anything on the base of cast bullets to be of benefit....merely placeing it between
and in direct contact with powder and bullet base..yes.
If this works for you could you provide some details plse.
