Chrono'd some Buffalo Bore 10mm...

[Mountain10mm]

After numerous chronograph sessions with some 200gr. Double Tap XTP and some really dissappointing results, I bought a few (expensive) boxes of Buffalo Bore.

DT's 200gr. xtp consistently clocked at 1106fps in my G20 - not anywhere close to the advertised 1250fps on the box. Not cool. I reclocked it again while testing the Buffalo Bore loads and this time the average was a whopping 1113fps. DT's 200gr. loads in a G29 came in at 1072.5fps.

Buffalo Bore sells 180 and 200gr. 10mm loads. The 200gr. is advertised at 1200fps and the 180gr. at 1350fps (both in a 5" barrel - I think). I didn't get to try the 200gr. load as it was not in stock.

Here are the results for the BB 180gr. Gold Dot JHC. Measured at approx. 12'.
G20 average = 1272fps G29 average = 1222fps.

Result Summary
180 gr. (Buffalo Bore)
(G20) 1272fps = 647ftlbs = 228,960 (power factor or momentum)
(G29) 1222fps = 597ftlbs = 219,960 (power factor or momentum)

200gr. (Double Tap)
(G20) 1113fps = 550ftlbs = 222,600 (power factor or momentum)
(G29) 1072.5fps = 511ftlbs = 214,500 (power factor or momentum)

Perhaps Buffalo Bore is money well spent.

Buffalo Bore is very good ammo. In 10mm I have found the 200 grain BB to be a little hotter than the DT. The DT is a little hotter than the CorBon 200 grain Penetrator. All three are very good loads for protection in the field. I would carry any of the 3. The CorBon is loaded with their own thick jacketed bullet designed not to expand on game. The DT is loaded with a very tough Hornady FMJ. I am not sure what bullet BB is using. It looks like a Speer TMJ. I am glad we have some options. If it was not for companies like these three the field and hunting load options would be pretty slim in 10mm.

That is complete crap that DT performs that way despite how they advertise. Might as well go with Speer Gold Dot .45 +P so you don't have to rely on ammo made in someone's garage. I've always suspected his ballistic claims were bunk too.
