I am finally getting back into the reloading mode and now with a Chronograph I am learning a lot more.

I have an angle eject Win 94, I shot the last Remington 150gr loads over the Chrony and had a range between 1919 and 2375fps, that was brutal. I have 60 150gr RN bullets I want to get rid of, not really concerned with accuracy as it is a lever gun. I loaded up 5 rounds with H4895, 30.5gr, 31.5, 32.5, 33.5 and 34.0gr, the start load was 2015, then 2211,2269,2300 and 2336 fps, no ejection issues or brass pressure signs, nothing that says stop.

I wanted to know if anyone else has a pet load, I was thinking of just staying with 32.5gr for the rest, middle of the road round, they all hit pretty much the same point of impact at 50 yards and this gun is not setup for benchrest.
 
Question, at the 34.0 load of H4895 are your primers flush with the base of the case?

NOTE, P.O. Ackley did a experiment and removed the locking bolt on a 30-30 Winchester and fired the rifle remotely. And nothing happened other than the primer backing out.
And my point being at the 30-30 max pressure of 38,000 cup or 42,000 psi the chamber pressure was not great enough to make the case stretch to meet the bolt face and the primers will protrude. Meaning when the primers are protruding and contacting the bolt face there is only approximately 400 psi on the bolt face.

The primers do not look flattened at all, they are Winchester WLR primers.

Lay a straight edge on top of the primer, is it flush with the base of the case or above and protruding?

The primers are not popped, there are no noticeable pressure signs on the brass or primer, the primers are flatter than the factory remington but not flat and not popped.
 
Depending on the manufacturer, it would still take 60K minimum (probably more) to start showing any degree of pressure signs in the brass. If you get to that point in a M94 action you're in an interesting place.

That was my thought too, 32.5gr felt good, looked good and hit about the max of the Remington factory load, so decent.

Funny thing, the 5 shot 3.5gr variation in powder had less spread than the Remington factory ammo, the remington stuff was really bad for consistancy, maybe this is why they say a 30-30 lever action is not accurate, the 450fps range for 4 shots is pretty bad.
 
All my primers protrude from the base of the case in my Winchester 94 Trapper model even at the listed max loads in the manuals with its shorter 16 1/2 inch barrel.

I have even had unburnt powder granules left in the barrel with IMR-3031. I now use 748 and a magnum primer to get complete combustion using Hornady 150 grain RN bullets.

And the bullets are all crimped and in over 30 years of loading and unloading I have never had a crimped bullet move.

This is why I asked about protruding primers and if you have protruding primers with your 20 inch barrels at or near maximum loading.

In the Lyman manual in the single shot Contender 30-30 section 748 is the accuracy load in a 14 inch barrel, and my load is 38.0 grains of 748.

I bought this 30-30 in 1982 and it has the Winchester name but the rifle is also marked U.S. Repeating Arms logo. And this is about the time Winchester sold the Winchester name to the workers in the plant.

Just wondering why about protruding primers in a short 30-30 barrel and apparent low chamber pressures and its possible causes, or if this is normal.

450 fps spread is incredible even in factory ammo.
 
the 4895 powder h or imr is good powder but for me in my jm marlin and savage 340 bolt 30-30s is w748 but never change the h or imr 4895 in my 35 whelen thanks have fun

Grab some leverevolution and load up that 30-30.
You'll never look back. D.

My wife has a Savage 340, I will be going to LVR when I go to load up ammo for her but at the moment I have 1.5lbs of H4895, 60 150gr RN and 95 170gr RN, to me there is no point in LVR unless I am going to FTX bullets or in the case of the savage spire point Partitions.

I so like the idea though, just not in the budget for it so going with what I have and shooting this gun more than the last number of years.

I just checked again, nothing at all.

Have you checked your headspace? I have had primers pop on very light loads, primers only for testing, not enough pressure to push the case back to seat the primer again but I have not seen this with any powder in it. I have seen some backed out primers on old Imperial ammo and the 303 Brit with very loose but passable headspace though too.
