Re: LONGRANGE 6.5-284
Hello Seal, Steve and Prime.
Seal, good choice.
Steve, As per the added length of the 30" barrel, my shooting friends and I have found that, the difference of 4 more inches will give at LEAST 100 FPS in almost any caliber.
100 FPS additional velocity works out to at least a 21" (using the 6.5 bullet, 155 gr, at 2900 and 3000 fps) flatter shooting gun at 1000 yards.
I know that John Hoover (shoots nothing but 6.5/284) who is an excellent shooter at Williamsport, maintains 2950 to 3050 FPS with 30" barrels and 140 to 142 gr bullets on all 4 guns that his family uses at the club matches.
30" barrels are a bit long to most hunters/shooters who have been used to 22 to 26" most of their life.
Point is, it's worth the added length for longrange shooting if a velocity gain can be made and 100 fps is certainly worth that additional 4" of barrel steel.
Prime, As per the BC of the 6.5 bullet, I can only come up with a .615 for the 155 Gr Sierra MK and .585 for the Sierra 142 MK.
If JLK is advertising the 142 at higher then that (.655), I will have to adjust my records as per his listing.
Please double check that listing, if it's true, I will shoot some of those bullets in my 6.5s AGAIN.
