Yet another IMR7383 range report

[sundog]

With jacketed at 200 yards for high power. Match was yesterday. I'm shooting a souped up many year old Mdl 70 in 30-06. Load is Sierra 168 BTHP match, 50.0/IMR7383, Win several X fired case neck sized, and a Rem 9 1/2 primer. Sights on the gun are Redfield Palma and Olympics - irons. My slow fire prone was 199-11X - kinda purdy, and I saved it. The onliest round dropped was solidly all in the 9-ring at 9 o'clock. Match started with foggy, hazy, clearing while shooting and bright sunlight by the time we got to SF prone. Had to contend with fogging glasses. Many sight elavation adjustment while shooting. My OH, RS, and RP were all good groups, but I just couldn't get them centered up right with the changing light conditions. So, for now I'm not going to change a thing. I'll take a 199 anytime. Aggregate was 724-15X. Good match and excellent training in light conditions. Two sighters were a tad low and I took yet another 2 clicks up. Time for record. My first shot on the SF prone didn't even show in the spotting scope, nor in my buddies. Damn hate to waste a shot, but gotta go. Second round an X. Mirage was terrible and the bull was in a boil almost the whole time. sundog

Sundog: gotta love that 7383- I've always liked a true bargain. A year or so ago there was talk about how "peaky"it was, want to see "peaky" try some of that Bofors manu RL15 once you exceed a true max load- now that is truley "peaky".

Scooter, It's not so peaky if you use starting charges for IMR 4350 with it and jacketed bullets. I've done this in both my .243Win. and .30-06 and was rewarded with excellent accuracy and moderate pressure levels. If, however, you try to substitute max. charges of IMR 4350 for IMR 7383, high pressures most certainly will result. I.e., don't even think about doing it!

Quit being so all-fired reasonable sounding about IMR 7383 pull down .50 cal spotter powder-- you are going to cut off my supply of free barely-used jugs being sent in to me for "proper disposal" if you keep saying the stuff works just about like a normal rifle powder would be expected to do ..........

Remember, Sundog's excellent accuracy and complete predictability aside -- every jug of IMR 7383 smells of ammonia/sour milk when you pop the top off of it. Every jug is exactly the same -- it smells like it is going bad. Let your wife sniff it, she'll tell you immediately that it is going sour and should be disposed of. It completely fails the female nose jug full of sour milk smell test.

All jugs IMR 7383 should be packed up immediately and shipped to me.

I have discovered that this soured disposal grade IMR 7383 (when stuffed slam full and slightly snugged up by bullet seating in a 30-30 case) gives me 1,635 fps on a FAT 30 slug and shoots like I should be ashamed to say out loud. You don't want your kids exposed to that kind of talk, so tape those jugs shut and send them on in.

The flag, Mom and apple pie must be preserved, send them sour, evil, bad smelling jugs of IMR 7383 on in for proper disposal !!!

Has anyone sent you the first one yet? I am hanging on to my supply. What's not to like about a powder thats usefull in 30-06 and 308 based cartridges. Gianni.
