Nice shooting Alan! What is the approx bc for that bullet? What barrel length do you have? Is this a hot load?

Hey Riley,
It's the 2nd of the two 6.5x47's I have. They were both built by Chris Matthews of Longshot Rifles, Missouri, now out of business. Great 'smith, horrible businessman. This one on a Pierce SA, 24.5" #3 Broughton/1:8, McMillan Remington Sporter stock, Harrell 2-port brake (so I can see the impacts) Rifle Basix Trigger @ 2.2 lbs, Pierce 20 moa base, Farrell alum rings and NF NXS 2.5-10x42mm with MOAR reticle. My brass has something akin to 22 firings on it since the barrel has over 2200 rounds though it. I using 42.3 gr of Reloader 17, Fed 205m primer and the 142 Matrix VLD seated .085" off the lands (3.003" using the Hornady Comparator) for 2917 fps and 5 SD for 10 rounds. In my rifle the load is stiff but i'm not seeing ejector marks nor stiff bolt lift and I ran it up to 42.6 gr with the same results. Not sure if the base of the brass is work hardened (anneal every 3x firing) and doesn't show ejector marks and since the bases don't get annealed or the Pierce action just handles the pressure, or doesn't show the pressure.
Published BC on the Matrix site is a G1 of .625. I used a G7 of .318, suggested by the folks here on LRH.com. Not cheap and Marshal's (owner of Matrix) shipping is ridiculous.
