Gunguirs, they will work in a .140 FB dasher, maybe too long for the Hammers.... jim
 
Ok thank everyone for the input.
I don’t have a lot of time for testing would y’all have any info on where to start the seating on the gunguirs.

In .010 and back out .002 at a time and you will hit it. 31.0 to 31.1 of H4895 will give 2970 to 2998 depending on the barrel after you get a 100 rounds down it. Fire form with 29 gr. of H4895....... jim

Maybe your jug of H4895 will do that - not sure mine would. Take care of the powder lot variances, perhaps take the suggested velocity instead of the suggested powder charge from this advice

I have 5 different lots and all will work with that or more but only two will shoot. Your free bore is a bigger factor, mine is .125 and with the short ones you may get pressure ..... jim
 
Hoping for a good Weekend! Shooting a the East West which is a points match for the World Team.

Hello Bart, I shoot primarily 7mm, in Fclass, and saw on your website that it says this caliber is coming soon.

With range closures, I’m trying the 190 A-Tip’s tomorrow for the first time at 1,000.

I was curious what your 7mm general plans are? Hornady seems to have gotten some shooters willing to ante the next “node” up for jacketed target bullets.
