Plenty good enough for deer hunting.

Is fatigue a problem when shooting groups with heavy bullets ?

Not really .

I generally take 4-6 rifles and don't shoot any of them all at once .

Last trip I carried a pair of 444's , one for the heavy stuff and then another I was shooting a 265 grainer with 31 grains XMP5744 . Thats a pretty light load by my standards think it was running about 1650 over the chrony for the average of 10 shots .
Also carried a 243 and a 25-06 .


Also with the heavy hitter I shot exactly 12 shots with the older mold and 12 shots with bullets from the newer mold . So 24 shots from that shoulder cannon spaced over two hours isn't so bad .

Think between the 4 rifles not counting foulers I shot 93 shots .

24 with the heavy 444
30 with the other 444
15 with the 25-06
24 with the 243

I felt no ill effects after the fact .

The very last shot was lackadaisical and went a bit high and made the last group pretty worthless for comparison. The 35gr groups were very consistent, but consistently a smidgen over 2" (2.13" avg.). The best group was with 36gr but the groups are less consistent and of course the last shot was with the 36 gr load. I am still trying to decipher today's data and I am not sure how to feel about it yet.
In the pic below, the two shots in the middle are the fouling/sight in shots. The 35 gr groups are on the left side and 36gr groups on the right.

They aren't so bad !

They'd be good enough for deer and black bear where I generally hunt . As 75 yards is about as long a shot as I can get most of the time .

I thought about this a bit more . When I worked up loads for my 375 H&H MAG it wasn't to bad as I was using a Nosler 260 grain bullet . When I did loads for my 416 REM MAG I got a load for the Speer 350 that wasn't bad , then later I worked a load for the Hornady 400 grain RN and that one would work on you .
Later I did my buddies 416 Rigby with 400 grain Noslers and it wasn't to bad . But when I did his 505 Gibbs with the 525 grain Barnes TSX it was a bit mucg after 6 shots .
With my old Marlin 1895 shooting the BallistiCast 550 grainer that one was okay for maybe a dozen shots and the BRP 462-465GC was okay for about 24 shots .

I will say however with a Ruger #1H 458 WIN MAG I used to have a 3 shot group with the Hornady 510 grainer was all you wanted . I never shot more then 9 shots of that load over an entire range session !

I am a firm believer that undue recoil causes stress and or fatigue !

And with that being said "generally" my 444 heavyweight bullets don't kick to much as I have a KickEez recoil pad that takes care of a good bit . Also had the thing restocked with a monte carlo and it kinda gets your face up and away or atleast I think so .

For me, I hardly notice the recoil if it wasn't for the fact that I have to re-set after each shot. I Don't feel any sort of discomfort or even a sense of concern about the recoil. I am built kinda like an offensive guard and I kinda like the physical nature of these big bullets.

Latest casting weigh an average of 418gr and that is with added tin/antimony, so I can imagine that straight wheel weight will be right about 420 as designed.
I dont think I have found the max load with H335 so I am going to proceed with caution. So far, I have tested this bullet with three powders, RL7, H4198 and H335. Of the three, H335 seems most agreeable with the Huckleberry.

I have about 20 pounds of Lino I may work in an alloy mix sometime soon .

To be honest I've had Lino in my stockpile for about 5 or 6 years and never bothered with the stuff .

I think RD goes 50-50 with WW's and Lino plus a teaspoon full of #8 magnum shot .

Long story about my last two weeks. I'll try to sum it up by saying I experimented with my Lyman M-die with seating depth and that experiment failed. Second issue was that it turned out that 43gr of H335 is a case full with the Huckleberry. I loaded up to 45gr but decided to using anything after 44.25gr. My first run of this test was negated by my M-die experiment so I repeated the test this week.
6-23-13 Chino Valley Shooting Facility H335 and Huckleberry max test 80 degrees 50 yards

This was the best group. The 4th shot on the left was my Sight-in/fouling shot but loaded with 42.5gr, the same as measured 3 shot group. The first shot of group went connected with fouling shot. The next two shots are connected above.
