Sooo... Where to start?
I picked the 53Gr VMAX cuz I really liked the potential numbers, well... Ive got some good ones. I started with BL-C2 and got no where.. slow numbers and no real accuracy.
i was getting 3150-3200 and averaging OVER 1" groups.. Switched to TAC, much better! Decent speed and some nice groups, well under an inch.. But I kept thinking, WWFD?? (What Would Frank Do)
Speed! This bullet has a BC of .290, Im gonna find a way to take advantage of it!! So pushed TAC a bit and the groups got bigger
On to Benchmark. I worked BM up to the book listed max of 25.0 and got some really sweet groups, like .5-.6" but the speed was averaging about 3187. Interesting tidbit, Hodgdon website lists the max charge for a 53Gr bullet at 26.0. So, you know where I went next! Groups got bigger at 25.2, 25.5 and 25.8, but at 26.0..... BANG! Back to .7" average and speed is averaging 3327! I checked lots of cases before and after and I don't see any signs of pressure problems, so I went for it! As of today I've now shot 50 rounds of this load, I put 10 more over the Chrony in 2 groups of 5 and got .63 and .73 with an average 3328 FPS, Extreme Spread of 36.57, SD of 12.64. Im impressed with Benchmark! Those are really good averages to me! I know lots of you guys can shoot better than .7" average, but 2 things.. Im shooting off a bipod and bean bag and Im really only concerned with "as long as it beats MOA" which means its plenty good for "Minute of Varmint" out to 400+ yards! (and honestly I get SOOO bored shooting paper, my A.D.D. gets the best of me quick!)
The 53 Vmax is pretty impressive with these numbers, if you use a ballistic computer, plug them in and you'll see what I mean. Plug in one of the heavier bullets like 68/69Gr and see just how close the numbers are, kinda cool.
Back to the title... It is seriously rewarding to put in all that researched and time to develop a load and then REALLY have it pay off. Im hooked! Buying a .300 WinMag soon, THAT will be the next BIG challenge!
Thanks again Gang and thanks Frank for recommending BM and inspiring my speedy side.
