Home Forums Hunting & Shooting Ask The Gunwriters 9.3 x 62 and big bear?

I believe you, and am not questioning your experience or results. However, gunner500 is reaching that velocity using Re17.

I know you are aware of this, but every rifle is different. I knew PO Ackley personally, and he told me one time that, just to see what would happen, he made a very long barrel and cut it into two equal lengths. I can't remember the length, but he made it.

He then threaded, chambered and headspaced the two barrels to the same action using the same reamer. When he chronographed the two barrels there was around 40 fps difference, IIRC.

Perhaps Re17 is the magic needed for really heavy bullets in the '62. I know it sure is in the 308 Win with 200 gr bullets.

Thanks Yukoner, my rifle is long throated to allow a COL of 3.340 with the big Woodleigh, the charge of RL-17 is just slightly compressed, that coupled with a 24.5" 12 twist barrel is the reason i believe these vels are possible in my rifle.

These are the RNSP's, the 320 gn Woodleigh protected point has a little higher BC and should be an excellent hitter at a little longer range if one was so inclined.

I didn't try R-17, and maybe that is the ticket. My main motive for suggesting caution is that pressures can skyrocket in the 9,3X62 with heavy bullets.

The 9,3X62 kills fine at the usual velocities. Blue-pilling it just doesn't seem necessary to me, but to each his own...eyes and thumbs...

i mainly conducted my podunk test to see the un-real efficiency of the '06 case in this dia, heck it rivals the 338 WM and the great 375 H&H in much larger hulls.

luv2safari,

I believe I bought that VZ24 from you and rechambered to 9.3x64 Brenneke. Test firing blew the primers out of their pockets with moderate loads.

After casting the barrel, it was discovered to be undersize. That is why you never got the velocity expected out if it. I replaced it with a Lothar Walther and issued resolved.

THAT explains a LOT!

I was shooting moderate loads with cheap Previ 286gr bullets into the same hole with it, but when I tried to hot rod it I wasn't happy.

I'm happy with a 9,3X62 that shoots 286gr bullets 2,300-2,350 FPS to match my 9,3X74R guns.

Did you shoot any groups with Norma or Previ factory ammo? I tried both, and it shot same hole groups off a steady bench.

My Husqvarna acted about the same as the ZV 24 with the 320s. I wish I had kept it, but a surgery needed funding.

Totally agree with you, and that is why I have stayed with 286s at 2400. The 9.3X62 has only had 105 years to prove that 100 fps less than that is plenty!

270s at 2500 work very well, too.

Ted

I never shot it as a 9.3x62.
Barrel was changed immediately after it blew the primers in two test firings. At least the action was proof tested, with no lug setback.

The LW barrel is fantastic. Shoots RWS factory 293gr TUGS at 2575fps consistently about 1". I cannot get it to shoot any 250gr bullets. Going to try the 286 Partition & Hornady's next week.

I'm sorry you had trouble with the gun. It shot my fodder well...so well that I almost kept it, but it went for the same reason as the Husq. Those cheap Previ bullets at around 2,320 were the most accurate 9,3 bullets I've ever experienced! Go Figure.

No worries. It is a solid, functional, performing rifle. Had CAS Cerakote and paint the stock, you would not recognize it anymore.

Definitely one of my favorites rifles now.

I can't get my LW barrel to shoot 250's either, except the AB at Max+ loads. Shoots everything else fine including 232 Normas and Woodleigh 320's.

Talking about the 9,3x62 it always amazes me the popularity of this cartridge and the obsolescence of the 9,3x64.
Even in europe, where metrical cartridges are far more common, you very-very seldom see one.

Will either know the difference - or care?

BBerg - Prolly b/c those wise Europeans figured out back in the 1890s that the 6.5x55 will drop all game when hunters do their part

LOL.

djs,

I don't know what you mean, but your same question would apply to 7-08 and 280, .308 and 30.06, 30-06 and 300... and for many other pairs of cartridges where both share the popularity of their diameter.
