Henson Aluminum tipped bullets test

Ok, now that I have a minute, I will be doing the testing of the 280 grain HAT bullets in wet phonebooks and comparing them to the 300 grain SMK side by side. I will also be doing a ballistic coefficient test as well.
It probably looks on schedule for Saturday but I thought I would start the thread tonight. Here's a pic of the test bullets:

The bullet on the far right is the bullet seated out a ways to show how long it is. The bottom of the bullet is actually at the body/shoulder junction! The other two on the left are loaded to fit a REM long action magazine. I loaded the 300 grain SMK with 50 grains of N170 and 48 grains are behind the 280's. I loaded them VERY light to simulate a 1200 yard (roughly) impact.

GG,

What about the 265 HATs? Any chance you have any left?

My 800 # boar arrives at 0800 in the morning. Am loading down to approximate 1K w/300 SMKs and 225 NABs in the 338 RUM.

Pretty poor selction of bullets but Cross from I/F may show up with several more guns.

Looking forward to your results.

It would be interesting to know what percentage of case capacity is lost with that much bullet in the case. It would be hard to order a reamer with a 1/2 freebore and hope those bullets liked that barrel. Have fun with your test.

Roy,

I have the 265's loaded up as well. They are in that loading tray but just out of the picture.

I don't think I will have enough phone books to test them this weekend too so they will probably get their own, independent test the following week. I already know what they do in comparison to the 250 SMK's thanks to Davewilson so I'll just shoot them into a different media than he did to see if anything changes.

I don't know about the HAT bullets, but I lost about 8 grains capacity with the 300 SMK's seated out to a similar length and then pushed in to fit the magazine!

Holy batcrap Robin! I totally lost a week here somewhere! I thought the br match was next weekend and I learned this morning it's THIS weekend! I'm getting senile in my old age. Better make the bullet test report the first part of next week. I've got to get my crap thrown in the truck and haul arse to the range if I'm going to make it in time! GG out.....
