Here is the test: Set out w some loads being saved up for the USH. Hope you like it. Pictures accompanying.
C-
Date: Fri 26 July 2013
Elevation: 764ft
Temp: 95 degF
Wind: 7 mph (
Humidity: 47%
Platform: NEF/H&R Ultra Slug Hunter, chamber reamed to 3.5”, 24” fully rifled bbl, forcing cone polished and smoothly blends w beginning of rifling, stock and forearm weighted: balance point ~1inch forward of trigger , total weight 11-lbs w/o scope, hammer w/ offset spur installed
Scope: el cheapo BSA 1x25 red dot w 3 MOA dot, which held up surprisingly well
Target distance: 30 yds unless otherwise specified
Notes: gun was heavy, fired from seated “double gun” position (hand under forearm and resting hand/wrist on stand, gun to shoulder, body leaning in; pulling snugly both down and into shoulder. No shooting jacket nor shoulder pad though- too hot outside!) Buttstock has really squishy pad on it (*)which made every recoil impulse ABSOLUTELY PAINLESS, even when kick was substantial. In fact, the muzzle flipped a lot (need to move balance forward w/ more weight but wont do that until a proper barrel clamp is had) and stock slipped down off shoulder w each shot of heavy loads; but still absolutely no discomfort at all. NONE!
(*): this pad, in fact: http://www.amazon.com/gp/product/B00081Q7E4/ref=oh_details_o04_s01_i02?ie=UTF8&psc=1
Load: Brenneke 3” KO Sabot for sighting in only
Hull: Brenneke
Primer: whatever Brenneke uses
Powder & Charge: whatever Brenneke uses
Wad column: whatever Brenneke uses
Load: 10z Sabot slug
Overshot (if any) & Crimp: roll from factory
Notes: shot well, about 3” at 30yds, even though not trying too hard, no pictures. Cases did not eject nor extract, needed tiny wooden dowel tap to pop out. Wad petals sheared off probably from being a short load and hitting that forcing cone, but there is no pattern to it- some are just worn down, some had all 4 petals ripped off, and some had a couiple. See pic.
Load: Hardcast Lead slug, fullbore
Hull: Fio 3”
Primer: Fio 616
Powder & Charge: 48gr IMR 4227
Wad column: X12X over powder, then 3/32 cork wad, then .17 hard Nitro Card under slug
Load: 1043gr hardcast lead slug .729 diameter, rolled in 0.5micron hexagonal Boron nitride powder
Overshot (if any) & Crimp: clear BPI Over Shot disc, roll crimp
Notes: shot well, lots of unburnt powder in bore similar to same load described in my old thread: http://castboolits.gunloads.com/showthread.php?199731-Safety-of-hubel-Sabot-in-875-muzzle-thickness-barrel/page5
Ejected easy.
Load: Hardcast Lead slug, fullbore
Hull: Fio 3”
Primer: Fio 616
Powder & Charge: 50gr IMR 4227
Wad column: X12X over powder, then 3/32 cork wad, then .17 hard Nitro Card under slug
Load: 1043gr hardcast lead slug .729 diameter, rolled in 0.5micron hexagonal Boron nitride powder
Overshot (if any) & Crimp: clear BPI Over Shot disc, roll crimp
Notes: This was my favorite load today! 50gr burned cleaner than 48, so I may go higher to 52gr. See pic, the three holes almost touching, though w such a big slug, its still abt 2 inches at 30yds. This may well be my go to load for this gun! I sighted in scope to this load and left it w/o adjusting for the rest of the day, letting bullseye float.
Load: Hubel sabot
Hull: Fed 3” plastic
Primer: fed 209A
Powder & Charge: 50gr A. Steel
Wad column: X12X, fiber wads to raise, .17 hard NC, Hubel Sabot
Load: 440gr .578 minie ball, lead cast
Overshot (if any) & Crimp: no overslug, roll crimp
Notes: picture attached. One sabot not recovered, one sabot recovered at abt 25yds w petals splayed unevenly (see pic), one sabot recovered at 10yds w petals widely splayed evenly
Load: medley of facotry rounds: 3” brenneke Black magic, brenneke 2.75” SuperSabot, Hornady H2K Heavy magnum sabot, and Sauvestre 3” Gros Gibier 329gr sabot (yes, the really expensive, funny looking one) (**)
Hull: per factory
Primer: per factory
Powder & Charge: per factory
Wad column: per factory
Load: 1&3/8oz Black Magic Slug, oddball 7/8oz .63caliber piston-like slug (***), hornady 300gr, Sauvestre torpedo fin stabilized slug
Overshot (if any) & Crimp: all roll, except Hornady which was star crimped.
Notes: That Supersabot zinged almost off the target. Wont be returning to that load in this gun anyway. I really wanted to harvest the Super Sabot and the Sauvestre since they are so odd. Maybe they’ll turn up someday.
(**) Sauvestre slug: http://www.centuryarms.biz/proddetail.asp?prod=AM1845 yup, like $10/each. All in the name of science, of course!
