Who shoots the 240Gr Sierra Match kings?

[JDJones]

I'm inthe process of building a new long range gun for shooting 1000yds+ and was wondering if anybody has shot the 240gr Sierra Match King bullets and if so whats the real BC for them? The gun is going to be a 30-338 Lapua Improved with a 31" barrel 1-9 twist.

I had a 30/338 LM Imp with a 34" 1-10" twist barrel about 5 yrs ago and was shooting the 240 SMK at 2880 fps at 2300 ASL using 80grs of H1000 which was very accurate.
When I shot it at 1 mile using the published BC of .711 it was right on for me.
That load was not a max load, with 105grs of WC872 I was at 3150 fps but not as accurate.

JD:

Scott Fletcher has shot the 240 SMK with great success at Hawks Ridge and in National matches in his light and heavy guns -- both switch barrels with additional 338-378 chamberings.

Scott's 30 cal case is based on an improved and necked down version of the .338 Lapua created by his gunsmith David Tooley.

Scott and David have done a lot of testing and they might have the BC answer based on their 43 chrono work. Scott and David also enhance the meplats by inserting tips in the SMKs, so the BC on their bullets is probably considerably above the unmodified 240s. You might want to give David a call.

Good shooting,
Jim Hardy
