HPBT and OTM bullets - Sniper & Sharpshooter Forums
May 24, 2011 · 68 posts · Joined 2008. #5 · May 26, 2011. Maybe so because OTM started out as a military acronym for HPBT match bullet. Look at the box of AE 168gr OTM. It states ".308 Win (7.62x51)". It is really a 7.62x51 cartridge. The bullet is a Speer manufactured HPBT with a cannelure. HPBT or BTHP is not "Hague" friendly.
223 load recommendations - Berger 77 gr - Sniper
Jun 19, 2015 · The Berger 77 OTM is a magazine bullet intended to be left at 2.255" COAL, not loaded out to touch the lands. It might be POSSIBLE to do so, but it may (or likely may not) shoot best there. "Berger" does not, in and of itself, mean that a given bullet is a VLD. It's what they were known for early on, but they make a lot of tangent ogive bullets.
What bullet does the 5.56 NATO FBI OTM round use?
Dec 28, 2011 · I think it added 50 meters to the 5.56 NATO. It actually performed worse terminally, because the bullet was too stable. It made .22 caliber holes, because of the tighter twist rifles needed to stabilize it. This problem has led to the development of the MK 262 Mod 1, which uses a 77 grain SMK, by the Special Forces.
77gr SMK vs Black Hills 77 OTM | Sniper & Sharpshooter Forums
Jan 18, 2015 · As according to Hodgdon's data, BL-C (2)'s max load with the 77 SMK is 24.9 grains @ 2800 fps out of a 24" barrel. Using some rough guesstimating, it's possible a charge of 25.9 of BL-C (2) could yield 2750fps from an 18" barrel, but the shorter base of projectiles in the Black Hills load could help keep pressures in a safe range which may be ...
Ballistic Coefficient for PRVI .308 168gr BTHP
Sep 5, 2008 · The sectional density for the PRVI is no different than any other .308 HPBT 168gr bullet, which is .253. With the known form factor of .532631579 the BC for 2600 -2100 fps is .447. The muzzle velocity for the PRVI .168 HPBT is 2608. Please excuse me if this is elementary to you. I'm a rookie trying to figure out ballistics.
Berger 175 OTM vs Berger `185 Juggernaut OTM in .308
Jan 17, 2017 · Thinking of trying the Berger 175 OTM and the Berger 185 Juggernaut OTM in a Sako TRG 22 .308, 26" barrel, 11 twist, shooting up to 1200 meters/1300 yards. I understand the rifle will eventually let me know what it likes better but was curious to have SC shooters' input on which bullet they would recommend and why (any load data welcome).
77 grain on 1:9 twists. Can it work?!?!? - Sniper & Sharpshooter …
Apr 19, 2008 · The 1:7 and 1:9 may hold similar groups at say 300-400 yds, but the 1:9 may destabilize sooner and produce a horrible goup at 500-600 yds were the bullet from the 1:7 barrel is still truckin. You may find your 1:9 likes stuff in the 60-70gr range too. There's a lot of match and varmint bullet choices and match factory ammo in that weight range.
338 lapua/300 gr bullets/2800 fps minimum? - Sniper
Feb 19, 2015 · Hi, Working on load development on TRG42/338 lapua mag with H1000 (89 gr), Berger OTM 300. As of now, good results up to 400 yards but didn't stretch it yet; MV is 2680 fps, very little SD. On the subject, I know a little, there is a lot more I do not know. I keep on hearing bullets (300 gr) should reach a minimum MV of 2800 fps.
reload thoughts 77 gr SMK .223 with Varget - Sniper
Feb 5, 2017 · It so HAPPENS that Sierra's own accuracy load for the 77 is Varget at 24.4 grains. They don't list max until after 25 grains, and Sierra is noted to usually be conservative. Last tip: ignore the speed if the accuracy and pressure look good. -Nate. NRA A2 …
So I was reading about the M852... - Sniper & Sharpshooter Forums
Apr 12, 2010 · I was reading an article online from the December 1996 gun-tests.com (reloading for match m14) and they were discussing a duplicate round for the LCM M852. They said that the load consisted of LC brass, a 168 grain sierra matchking bullet, and a powder charge of around 41.5 grains of IMR 4895. Bullet was seated to 2.800 OAL inches.
