Good Hunting,

Have you ever tried down loading your big bores?
About the most fun I've had with my 35 whelen was launching 150-200 gr pistol bullets at 800-1300 fps. I plan to work up similar loads with my 500 Jeffrey using 350-450 gr pistol bullets @ 800-1300 fps.
The nice thing about downloading powerful rounds is you still have the option of runnign them full patch. A properly built gun will be accurate with mild, mid level and full patch loads.
I totally agree with Paul on this.
There is something about reduced loas in bigger bores.
My current favorite load in the 375 is 39 grains of our Australian powder ADI 2205, which I think is sold as H4227 over in US land and with a 220 Hornady flat nose.
It shoots ragged hole groups from a match grade barrel and does a bit over 2000 f/s.
These reduced loads almost have a "slow motion" feel to them. They feel more like a big rimfire rather than in this case, a super accurate 375 Winchester lever caliber.

I�m not recoil shy, but I have my limits regarding shooting big rifles accurately, and like to take that into concideration before jumping into a new project.

Anyhow, I did find that 15 gr unique will push my 200 gr cast bullet 1420 fps, and it'll group them pretty well at 100 yds, and with basically no recoil. The funnest part is hearing the wap the bullet makes when it hits the cardboard backer just a tad after the report of the rifle. I'll be shooting alot of these in the future, very, very fun!
I still have some work to do on the stock, but yeah, I'll have to post some pictures. I just need to figure out who to borrow a digital camera from.
As you know from my other thread the odds are very high (in fact I think I am over the line) of me chaning over M70s for CZs.
416 CZs are cheap and perhaps my original suggestion to you on 350 Rigby may come back and bite me hard
Do you think if Bertrams are used or 375s with rim reduced to .520" that they will still be OK through a CZ 375.
You don't need a barrel lug on 375 so a switch barrel could be done between 350 and 375. I hav eno real experience with Mauser based actions but I imagine that with the screw position on the CZ, it should be like a Rem 700 or M70 and not need bedding under the barrel.
Maybe 416 and 350 Rigby and 465 H&H and 375 H&H The CZs open up some other opportunites.
I would think the 375 extractor and bolt face should be OK as there would only be about .006" per side.
Do you have to alter extractor groove on 375 cases for your rifle?

I'm also curious about how the 350 case would feed through a 375 magazine. Since the body taper is the same on a 350 as a 375, I would see if you could get ahold of a CZ 375 and run some 350 rounds through it.
Yeah, you infected me with the 350 bug, but I'm glad you did. The re-chamber cured the ills of the original sloppy whelen chamber. I do burn a few more grains of powder now, but other then that, no problem.
Tell us more about the .400 Tembo! This round sounds like it strikes a great balance between adequate power for anything not extinct and dinosaur gun.
