Hello Gun Nuts,


So thusfar we have had a 375 bullet test and a .366 on the way.

I have made this thread to gauge interest in having a .338 bullet test along with these. I would be willing to load and shoot the projectiles into some kind of dense test medium. If anyone in the Calgary/Bow Valley area has private land where this could be done that would be great, but not strictly necessary.

Here is a list of the projectiles which are currently avaliable:


200 gr. Hornady Interlock # 3310
200 gr. Nosler Bal. Tip.
200 gr. Speer Spitzer.
210 gr. Nosler Partition.
210 gr. Barnes X.
225 grain Barnes Solids
250 gr. Hornady Interlock # 3335.
250 gr. Hornady Interlock # 3330
300 gr. Woodleigh PPSN





If this goes ahead I would like to solicit donations for a handful bullets in the 275 and 225 grain range, more 250's and 300 grain noslers.


A shout out and big thanks to the venerable Kevan, who donated many of these projectiles.


Let me know what you think, fellow nutters. :wave:
 
^ would be nice to have a 250 grain spitzer in the mix. Did you get your hands on a .338 fed Brad?

For now, I am just gauging interest.
 
Pretty sure this is something BC Steve has done before. Might want to get some ideas from him. Think he uses wet newsprint....lots of it. Uses a chrony and sets a velocity. For example, i think he set the 6.5mm test to mimic typical performance of a 6.5x55sm>>>>>a projectile thrown at 6.5x55 velocity is going to perform much differently than one at 264wm or 26 Nosler velocity.

I have a good supply of various 338 projectile, let me know what you are looking for as i might have it.
 
I'd be very interested! As NWS said, different velocities will have very different results. Will you be firing the projectiles out of a couple different cartridges, if you have access to a few .338's?

I'll be following this thread closely. I currently only have some 225gr Speer SPBT, which I could part with a couple. I also have some 210gr Partitions that I managed to find in a haystack....you can't have them! :p

EDIT: I see you have the 210gr Partitions...excellent!
 
Thanks for your responses guys.

I don't own a chronograph which may be an issue. My plan was wet newsprint backed up in a wooden box ala the "ballistic buffalo" without the inner tubes.

My plan was to use the .338 wm and load all at the median charge suggested by their manufacturer. My reasoning behind this is that different bullets perform at different velocities; this is a function of their design, no point shooting bullets at a velocity they aren't intended to be used at.

The .338 win mag shoots a wide variety of bullets at a wide variety of velocities, this is the variable which changes in this test. They would all be fired into the same medium; and use Hodgon H4831 for all loads. Our "responding variable" here would be performance of the bullets in the medium at their intended velocities.

I think this has just as much info to offer us as a test with a fixed velocity; simply because of the wide variety of bullets. I suppose if a 340 weatherby was used we could put 300's at the same velocity as 210's but that precludes me from doing the test and doesn't make that much sense.


Like I said just in the idea stage atm.
 
What range are you shooting the target at. A 100 yard impact would be nice if possible. I'd like to see how the sst 225 gr holds up if you choose to test it. I may add a 338 federal as a common hunting gun
 
Because of bullet cramping for some of the bigger projectiles, the velocity is going to be all over the place. Say a 250 gr Partition at 2600 vs a 210 Partition at close to 3000, the resulting bullet expansion and penetration is going to really give the wrong impression about terminal performance without a chrony. Tough bullets at a slower speed are going to penetrate without expansion, and frangible bullets at high speed are going to explode with little penetration.

Need the chrony readings to put everything into context. Further, if your 338wm can only push a 300gr bullet at say 2350, someone with a Wea,Rum, or Lapua could still use the expansion and penetration results for a idea of what bullet performance would be like at 100...200....300. Based on their starting chrony velocity and yours.
 
I have some old 250 Speer Grand Slams, some original WW 250 Silvertips and some what might be 210 Partitions or 225 Hornady's I can send you.

Actually curious how the Silvertips will stack up.

Send me a PM if interested
 
^ I can borrow a chronograph. AFAIK the recent 375 bullet test fired all the different weights at their starting load velocities.

Thanks for your responses everyone and to Phil, Pickles and NWS for your PM's and offers of bullets. Like I said we are more in the ideas phase atm.

I did size and prime 100, .338 WM brass last night though.

I would really like to have a spitzer and a roundnose at least for each bullet weight, and preferably a variety of manufacturers.
