Quik load Question

[baltz526]

Is there a 300 Weatherby Magnum Ackley Improved listing. If there is, Can you run 165gr Ballistic tip at 3.585" and 180gr Etip at the same. I have 8lb of H1000 and IMR7828. 26" barrel.

 

[Ridgerunner665]

That round is not listed on mine...I looked the other day when this was mentioned.

 

[kraky]

All you'd need to do is change the case capacity from the normal wby to the measured h2o capacity of the improved casing.

I believe that to be true...but since I wasn't gonna be the one risking my fingers and eyeballs I didn't go there.

Same goes for long free bore (saw it mentioned here somewhere)....adjust the QL capacity and/or seating depth to make it match.

 

[baltz526]

No freebore to speak of on this chamber. I have read where 5-7% increase in powder capacity after fireforming a 300 weatherby factory load. It will be interesting to see if this is true. I'll wait for the New Bolt to fireform. Nosler lists 88.8gr of water capacity when using a 165gr. If I adjust for the OAL I can go to. then add 5%-7%I get 93.5gr to 95gr of water capacity when using the 165gr BT. I think this is a conservative # due to it list more case capacity under the 180gr-190gr & 220gr. It lists 96gr capacity for the 125gr Ballistic tip. If you run a 165gr BT at 3.585" in a 26" barrel using 96gr of water capacity And post it with disclaimers or PM it to me I would be grateful.

 

[Ridgerunner665]

Will do after supper

 

[Ridgerunner665]

I went with 95 grains capacity (6% over factory)...use at your own risk.

[baltz526]

Thanks a lot. 90gr H1000 is about where I assumed the max would be. 3200fps and 55,000psi might not be too bad for Recoil. But only 75fps over my 300 win mag. I'll post chronograph results as I do load work.

 

[kraky]

Be careful w/that work up. Years ago a friend w/lots of play money had 2 300 wby's made up. One a lightwt w/freebore and one w/a "match" grade barrel and no freebore. We got a load for the freebore gun first and it was well within published wby load data and did fine. We dropped it back 3 grains and fed it to the one w/o freebore and promptly blew primers!
Start w/ some conservative loads then run the results against the forecasts and see where you land.

Its real possible you won't exceed a normal factory wby.

And of course wby brass vrs rem is a whole different story as far as capacity goes.

The wby brass is softer and will give you feedback re loosened primer pockets and extractor marks better.

 

[baltz526]

After fire Forming a couple cases. The above Data is going to be very helpful. Water capacity of a case filled completely to top is 100gr in RP brass. I will be able to load up to 94gr of H1000 to base of neck If Pressure is not overly high. So the case is just Slightly larger than a 300 weatherby 2% is about it.

Baltz526,

If you don't mind, fill a case to the top with H1000 and weigh the resulting amount of powder and letting me know how much does it weigh? I want to try something over here and see if it jives with quickload and your test results when you get them.

Thanks!

 

[baltz526]

99gr H1000 completely full

 

[Wyo7200]

Thanks baltz526 for that info.

Ended up being ~10gr below the Noslers published min. That's the farthest I've seen it away from published load data. Very good to know and thank you again for your help.

 

[baltz526]

I ran a Couple rounds over the chronograph, 165gr Ballistic tip, 84gr H1000 gave 3170fps. From the Quick load Run

Hodgdon H1000 107.0 92.7 6.01 3308 99.5 61056 13033 1.163 ! Near

With The Weatherby Data as a Base Line, It looks like I'll get the Velocity at a lower powder charge. About 87gr should give 3300fps. I suspect this will also be at max for this rifle using H1000. Accuracy was apparent

Some very nice People Dropped off a Box of once fired 300 Weatherby Brass yesterday. After they left, I proceeded to Compare Measurements of the once fired cases against each other. Useable Capacity of once fired 300 Ackley Magnum 90.5gr H1000. 300 Weatherby 90.5gr. With IMR7828 88.5gr in each. They have Exactly the same Capacity. Next I measured the case, To see if I bought a 300 weatherby Die set, Could I use it to Size Fireformed Brass for the 300 Ackley. Every measurement Showed, with A Die Adjusted to Neck size, Too just off bumping the shoulder. It should work. I ordered A set of Lyman 300 Weatherby Die from Amazon for just under $42 shipped Free. If My Gamble works, It will save a Couple Hundred $ for Custom Die set. Stewing on the Logic Someone used to Justify, Cutting a Chamber for a Wildcat With Exactly the same capacity as a Commercial Available Case. I can only come up with Efficiency. Without the Freebore of the Weatherby, Bullet seating is Traditional. This Chamber is cut to Seat a Bullet Like a 165gr HPBT Match at Max Magazine Length and Get .015" jump to lands. The Logic Is sound. But is it Practical for a Hunting Rifle. Not so much in my Opinion. A standard 300 Weatherby would do Everything With Factory Ammo, The Custom Chamber Needs Custom Ammo for. With the Additional Hazard added. While 300 Weatherby Fit the Chamber, Cycle through the Action Perfectly Well. It is Over Pressure in the Ackley Cut chamber. Because it was Loaded for the Weatherby Freebore. While it is Nice I can Buy 300 Weatherby Brass and just Load it Exactly the same as My Fire Formed Brass. The 300 Ackley Magnum Or 300HH Improved 40deg, Depending on What you want to call it. Is not A real Good idea for a Hunting Rifle. Long Range Target Rifle? An Argument could be made for this Application and Justified.

I'm not sure if this will help , and please do some checking on this before spending any money . " I think " a 300 weatherby AI is known as a 30Hart . I don't know about the freebore in a 30 Hart . Bobby Hart , R W Hart gun smith , nescopeck , Pa has this .

 

[baltz526]

Here is a bit of Result Data. 165gr Ballistic tip 86gr H1000 3250fps. 165gr Ballistic tip 82gr IMR7828 3320fps. These are Close to Max loads. In Fire Formed Brass. OAL 3.590"

 

[baltz526]

My Thought is at 5gr less powder I'm getting Equal Velocity to the Quick Load 300 Weatherby data Above. This might be interpreted as the 300 HH Ackley Imp 40 is a More Efficient Case.
