New Howa Mini Action in 7.2x39

Post by eddahenry » 15 Dec 2018, 7:33 pm

So picked up my New Howa last week took it for a little range time
Very fun little rifle to shoot ,, low recoil super short action
They action is so sort that you cannot short stroke it even a little bit or you wont pick up a round
Is in A boyds thumbhole stock
with a 1-4 FFP 300BLK bushnell optic

I’ve put two mini actions in Boyd’s stock now. The 223 wouldn’t even pick up a round and the 6.5 Grendel which I’ve put in Boyd’s At-one won’t pick the last round from the magazine unless I push the magazine up with my hand.
I’ve fixed the 223 now.

I didn’t experience the same problems in the factory Houge stocks.

Does it use 308 projectiles or 312? And what twist rate do they come with?

I thought they might run a slower twist like a 1:15 and use 110 to 125 grain pills. What are you going to shoot in it.

The chrono results aren't too bad. Are you sure the SST is the same bullet as the ZMax. The ZMax shoot great but the SST are a pain to get to shoot anywhere near half decent. I thought the ZMax was a Vmax with a different colour tip.

I've bene toying with buying one of these but how does the 7.62x39 compare to the 300 Blackout? Might take the advice I generally give and just get both....:)

in most cases yes
they have never Made a Vmax in .310
i have measured every part of them ,, weighed them , cut them in half they are the same thing
the biggest giveaway is the CANNELURE ,, No VMAX has a CANNELURE only SST and AMAX
Only in the 123gr Zmax SST
all group sizes where similar through the powder range for both SSt and Zmax , best group was both the Zmax 27 Grs and the SSt 27 grains (pictured above) most groups where around the inch ,, biggest being 1.5 inchs
all loads where 40tho off the lands
i did this test buy loading 5 shot groups of
ZMAX 123 Gr 25Gr 2207 AVG FPS 2331
SSt 123 Gr 25gr 2207 AVG FPS 2324
ZMAX 123 Gr 25.5Gr 2207 AVG FPS 2372
SSt 123 Gr 25.5gr 2207 AVG FPS 2379
ZMAX 123 Gr 26Gr 2207 AVG FPS 2399
SSt 123 Gr 26gr 2207 AVG FPS 2423
ZMAX 123 Gr 26.5Gr 2207 AVG FPS 2478
SSt 123 Gr 26.5gr 2207 AVG FPS 2482
ZMAX 123 Gr 27Gr 2207 AVG FPS 2507
SSt 123 Gr 27gr 2207 AVG FPS 2503

Very interesting to see your data. I know nothing of this case but it is similar to the 30 BR. With that case you can stuff 34 grains into it and get velocities around 3,000 fps with a 125 grain projectile. Are you able to get much more powder into your cases?

I see what you are saying about the .310 bullet from Hornady. The ZMax is half the price of the SST so I wonder where they save the money. In a .224 the 50 grain ZMax has a cannulur but the Vmax does not, not sure what Hornady was achieving putting it there.
