The 309JDJ is great for deer, but the 375JDJ is the best for elk (or even the 338#2 or 358 JDJ's). Parent cartridge for all is the 444 Marlin.
I'd love one of those if I thought I could find one at a reasonable price...
Prices are reasonable for the SSK JDJ barrels - they are worth every penny they cost.
Since TC jumped on the 375JDJ bandwagon though with their factory barrels chambered for it you can go cheaper from them. SSK probably still has the best deal on dies.
What the hello is a G1? Never heard that term in over 30 years of shooting Contenders until sometime soon after the G2 came out in 2K. IMB there are Contenders and there are G2's (or G2 Contenders).
