I suspect, but am not certian, that my loads are safe given that Factory Federal Loads I have tested would appear to be even more dangerous than the IMR4831 (and H4350) loads I have tested (i.e., have the same craterering but EVEN MORE PRONOUNCED EJECTOR MARKS THAN MY HANDLOADS). However, as my...

with the H4350 loads, the temperture was in the 10-15 celsuis range - July temperatures in Iqaluit, Nunavut - i.e., the Canadian Arctic with the IMR4831 loads, the outside temperatures were approx in the 20-30 celsius range - Hot August temps in Ontario, Canada. However, my test loads where...

Thanks Divernhunter. However, the Barnes #3 manual has data for both H4350 and IMR4831 for 180 grain pills - the max's listed for these powders in this manual all higher than the loads I used (should be lower, as the Barnes#3 manual is for the "stickier", and since discontinued X-bullet). I used...

Hi Rick - interesting findings - fired factory brass tonight (Federal 180 PSPs - 2 rounds) I measured the headspaces. The results are as follows: 2 Factory Federals rounds Round 1 Before = 1.725 (same as twice fired brass that I used to determine the headspace of my chamber as...

Do you PFL resize or neck size your .300 WSM brass for hunting loads and/or your brass for reloads? I have read a number of posts that suggests FL resizing in not always necessary for the .300 WSM (and other calibers), whereas, the general advice in popular magazine articles is to FL resize your...

Thanks Desert Fox, However, I am actually using the Barnes TTSX. I only mentioned the Swift Scirocco because the Hodgdon online data for 180 g bullets of this flavor are pretty much idential to the Barnes #4 data for the 180 TSX/MRX data (and supposedly, TTSXs). Where there is a difference, the...

Check out the 6mmbr website - in the archives section is a very informative article on neck turning - I am confident that you will find it extremely helpful.

I am loading them .050 of the lands. I don't know about compression. However, I have I used 63 grains as my max. I find that load data for the Swift Scirocco is generally identical and sometimes slightly higher than the TSX data - 62 grains is the min and 66.3 COMPRESSED is the max for the...

Getting frustrated with my .300 WSM load development. Tested IMR4831 with 180 grain TTSXs with phenomenal results (3 holes touching on one loading) - unfortunately the two chronies were not picking up the speeds AND upon examining my brass, I started getting clear ejector marks on the brass with...

Regardless of whether the brass is new or not, you should make sure to FL resize all your brass to ensure the shoulders's of your brass are consistent. Otherwise you will have inconsistent trimming (e.g., some cases trimmed into the shoulder, other not). I personally trim my cases after...

Hi POP, Hoping you will help me out. What is the the Quickload Max for a .300 WSM + IMR4831 + 180 g TTSX combination. Using data from various sources (but none for Barnes Bullets), I was going to use 67.6 grains as my Max. However, I am somewhat uncomfortable, as the IMR4831 Data that I have...

POP (or Anybody Else) Read the Berger Article - Interesting. Have you had an opportunity to get results for your planned .300 RUM test yet. I don't want this thread left by the wayside. I am close to selecting a powder for my .300 WSM, so bullet-seating tests are on my to-do list. If this...

I hunt Caribou- but polar, seals, beluga, Narwhal and Walrus are what the local Inuit would hunt (Qalunaat, or non-Inuit, do not have to hunt this other fare). Muskox, barren-land Grizzly, and more recently, "Grizzlors" (polar bear/grizzly hybrids) can be taken on the mainland of Nunavut, but...

Thanks for the input guys. Shoot it is and leave annealing for after. Neck sizing is now in my future - I just orderd a Lee Collet die and an sinclair body sizer (for when I may need it). I wish ordering primers online was an option - life would be so much easier (I live on Baffin Island in...

My predicament is this - I have primed my resized brass, some of which may have been fired as much as five times. I am concerned that if I fire this non-annealed brass (yes - I just learned about the need for annealing), I may (a) be taking a safety risk and/or (b) it will negatively affect the...

Measured the various Barnes Bullets I do have - answered my own question. Bullet shapes do make a difference - sometimes a big difference in distance from case head to ogive Examples of various 180 and 165 grain Barnes Bullets (OAL to ogive at a distance of .050" off the lands 180 Barnes MRX =...

I have both the RCBS prescison mic kit and the Hornady OAL guage. I personally preferr the Hornady product for determining seating depth. However, I have often wondered if the common criticism of the RCBS precision mike is valid (i.e., different bullets have different ogive lengths). If the...

Would I be remiss in using a 150 grain Etip, TTSX, or GMX with a .308 Winchester for moose. I hunt Eastern Canadian Moose, and I'd say the majority of shot opportunities will be 100 yards or less. My uncle has harvested 17 moose in his lifetime, and only two exceeded 100 yards - a 120 yard shot...

Sorry for causing confusion - I meant neck turning (not case trimming). I believe 30-338 got it right. As I trimmed the cases to minimum specs for a .300 WSM (2.090) using an theRCBS case trimmer, I am certain the shaving I am taking off the shoulder is not due to an uneven case length...

I just started trimming my .300 WSM cases with my brand new Sinclair trimmer. I followed the instructions provided with Sinclair NT-1000 case trimmer to a "T". After trimming 12 cases, I noticed that about half-way up the shoulder on 6 of them, a small, thin shaving of brass from the shoulder...
