Browning Bolt 300 Winchester Short Magnum

by The Norseman » Mon Jun 01, 2020 10:05 am

The Browning A-Bolt, Deep Blued, Walnut Stock, Engraved Receiver,
Adjustable Tuning Muzzle, and Scope.

I have shot it several times. Very nice. Appears to be accurate. Not
use to something this powerful, since I shoot Revolvers mostly.

If you Reload for the 300 Winchester Short Magnum,
what are you using for a Reload? Elk?

I had 20 300WSM (prep'd ready to reload) sitting on the Bench.
I did the Research; my Manuals, Handloader Magazine, and Internet.

I decided, 5 rounds, Hornady 165gr BTSP #3045/65.5grs IMR4350/
CCI LRM #250/Win. brass/3000fps? (Hornady 10th Edition).

Thank you in advance for your replies.

Good afternoon Norsk. I have a Browning stainless A Bolt. Without the BOSS system mine is picky. It shoots three bullets well. The Hornady 150gr SST, but I can't get it to factory velocity without pressure and the recoil is a quick jab and bothers me more than the heavier bulets. So now I shoot two bullets, the Hornady 178 gr ELD-X and the Nosler 180gr Partition. For the past three years I have only shot the Hornady ELD-X with 67.8 gr of R19. Velocity is just over 3000 fps which is faster than factory, but not unpleasant to shoot.

I shot a large black bear in Montana at 397 yards with the Hornady ELD-X striking it in the right front shoulder and recovering it from under the skin of the left rear quarter.

Say. As I was doing my Research, I noticed some Reloaders using
Magnum Primers and some Reloaders using Standard Primers.

What Mag. or Std. primer are you using and why?

As you can see above I am using CCI Large Rifle Magnum
Primer #250.

thanks

I use magnum primers when I start dropping powder charges over 60 gr. One of my old Speer manuals recommends magnum primers for spherical powders in cold weather. I have only encountered one sort of hangfire with H414 in a 270 Winchester at a temperature around 0 degrees. In my high volume shooting like with a 223 or 22-250 I like to use spherical because I don't need to trickle every charge. I don't use magnum primers in those smaller cases and have had no problems with spherical down to -20 degrees. I have had no problem with TAC in a 6.5 Grendel or a 308 Winchester. Also no problem with CFE223 in any of my rifles that I use it in including the 200 gr ELD-X in a 308 Winchester.

I do the same in my rifles, except 55 grains is my cutoff. Had a hangfire in a 3006 using IMR 4895 at 20 degrees.

In my 300 win mag I use 165s for deer sized game, 180-200 for elk and such. My preference is Noslers as the rifle really likes them and shoots them well. Accubonds and Partitions for the 180s to 200s.

My rule of thumb for heavier game is shoot the heaviest bullet you can get close to 3000 fps.
