If you like short barrels (10") you'd be better to handload the 30 Herrett
14" or longer barrels will deliver the 30-30 at adequate velocities
If you're bold enough, consider the JDJ's. The 375 JDJ is a real performer!
375 Win is always a consideration, tho.
I appreciate your expectation of accuracy and I have much more experience with my contenders than I probably ever will with the encore.
I find Encore triggers to be a good bit heavier than any of my contender frames.
Hand-loading for the specific cartridge has always been my first attempt at...
They already have the 400 Legend out now!
Here's my '400', it is a wildcat 405 Win barrel on my Encore
Furniture is walnut with Boxwood accents by me... a real shooter!
