reloading for 300 Win Mag - Shoulder Bushings for Redding S die for

[Mudduck]

New Rifle and about to try something new - could really use some help

Reloading Benelli R1 semi 300 Win Mag - thus I need to go full length die but wanted to try out one with bushings.
I have never used bushing die sets before - Im considering Redding Type S FL with shoulder bushings for better bullet tension which they say is better for semi's

Any suggestions on which bushings to start with since I dont have the rifle in my possession yet? and I assume someone has used this die for a Benelli?

I shoot Barnes TTSX and Nosler Accubonds 150 - 180 grain. Any suggestions of which powders you get the best results with.
I was looking at IMR 7828. Retumbo, H1000 and Hybrid 100V

Any inout appreciated

I assume you mean neck bushing die. There is also a body bump die.

Neck bushing will depend on the size of your loaded round at the neck.

If you can't load one up yet then take the (neck thickness x 2) + .308 will give you loaded size [eg: (.015 x 2) + .308 = .338]

Then decide how much neck tension you will want. .003 would be a .335 bushing .004 would be a .334 bushing, etc.

Hi CyaN1de
From the Sinclair website this is what they say about the die
Redding's Bushing Full Length Die will full length size your cases and allow you to control case neck tension at the same time. These dies use the same bushings as the Type S Neck Sizing Dies or the Competition Neck Sizing Dies. The adjustable decapping rod allows you to size all or a portion of the neck. Decapping rods come with a standard expander ball and a decapping pin retainer like the Type S Neck Dies. These dies give better neck tension control- especially for semi-auto rifle shooters who need to full length size their cases every time. Available in over 70 cartridges. Bushings not included.

I do have the equipment to turn the necks so I was hoping someone who shoots this caliber ans rifle might be able to give me a starting point as to which bushings I might start with - or can it be done that way? I do understand about getting the measurements after you have shot a round and are reloading but where do you start when you are starting from scratch with a new rifle/caliber etc

I've got both neck and FL Redding bushing dies for the .300 Win. When I checked them it seems that I have .334" in both of them.

You asked for input; so here's mine. Unless you are shooting a match chambered tight necked rifle with turned necks I'd forget you ever heard of the bushing dies. The comp seater is nice if you don't have anything else to spend money on.

Thanks for the input Dogleg
I have a Forster sweater die - so far they are my favourite out of any I have tried
What powder (s) do you find work well for your 300 win mag . Plan to use Barnes and/or Nosler Accubond. 150-180 Grain depending on if its moose or deer we are going after

I've got 4 .300 Wins and am using H1000 in all of them with 180s. There is one that I use IMR 4831 and a 168 Barnes TSX in much of the time. Its managed to drag me a few places and kill a few things.

You don't need the rifle at all to determine the proper neck bushing. You don't determine the proper bushing by measuring a fired case. You load a round using the brass that you intend to use, and measure the neck diameter of the loaded round. Then you subtract .002" or so depending on the action, and the usage of the rifle, and that is your neck bushing size. Just be sure that you use the brass that you intend to use in the future, because the neck thickness of the cases does vary from brand to brand, and even from lot to lot. If you know anyone that has dies, and can load a dummy round for you, give them a few cases and bullets, and seat the bullets, and measure the neck diameters, and you are good to go.

Hi Stubblejumper
Thanks so much, now i understand what I was missunderstanding when trying to figure bushing size. I had mixed up some information regarding other measurements for other purposes.
