I've used the A Frames in .30 and .416 calibers. Like you stated they are very good bullets when used for their intended purpose. Your pressure problem may be due to the brass if you are using fired factory loaded rounds. I've had trouble with factory loaded Rem 300 Wby and Federal HE 338 WM...
I would read and heed the pressure signs you are seeing on your cases. the Swift bullets are pure copper jackets, as well they have a heavier jacket than most bullets. You also have to consider the bearing surface is different for all bullets. You could give swift a call, they may give you a...
Another way to estimate pressure increase that you don't hear much about anymore is measuring the case web OD .200 above the case base for non-belted cases. It is best to use a micrometer but a good caliper will give an idea of what is happening. Rule of thumb I use on once fired cases is at...
All good thoughts posted above. Getting a swipe on the case base is way to much pressure. You want to look for faint ejector marks on the previous fired case as you should see signs of pressure before a swipe. I would back the charge down 2 to 2.5 grains and work from there. RL 26 is great...
I've been using a Lyman Universal for years. Has worked great, I generally don't trim over 50 to 100 cases at a time so it's plenty fast. universal shell holder works good and it comes with all the pilots I use.
Anyone used Nosler brass in 300 Weatherby ? I'm needing to build some new loads and thought I would give it a try. Currently using the Nosler brass for my 30-06 AI and have had great results. May have to look at Hornady also.
Midwest Gun Works has a good schematic on the model 70, as well all the different parts used for different calibers. Think the magnum mag box (375H&H / 300 WBY) is 3.6 inch coal.
Good call, Thinking on this It would have been better to not put any percentage on the thread and just said where to find the information. Hodgdon does a good job of explaining the process. Hope everyone would go to the original source before using this data.
Hodgdon has a reduced load formula for H4895, it is 40% reduced load from the max powder charge. You can find the info on it on the Hodgdon site. It is under the reference data section. I used to load 6mm Rem and 30-06 loads for my son when he was starting out. Trick may be finding a H4895 load...
Don't know if you sent your dies with the gun. If not I would load 5 dummy rounds of the primary load you will be using. Box them up and send them to the smith with a note of any concerns your having. Doing this will eliminate any doubt as to how the gun functions and what you expect. Hope you...
