    so, i was out today sighting in one of my (my wifes) deer rifles. i put a different scope on, and i wanted to zero n @ 150 yards, instead of 100. so i was using some home loads that i just popped out of one of the reloading manuals. i loaded 1/2 way between the start and max load. using remington core locts (30-30) and i was using them just to get close before swithcing to what we usually shoot. which is winchester 150 grain hollow points. anyawy, the accuracy of these re-loads was not really all that great:barf:. and i guess i have just been lucky in the past. because usually, most everything else i have loaded (which admittedly is really not that much) has been fairly accurate. well, at least i thought so. i actually am entering into a whole new world here, as now i have a portable shooting bench, and a solid rifle rest from which to shoot. instead of the old "lay it across the hood of the truck" method. so what is the best way to go about getting great accuracy from my reloads. start at the starting point and work up by 1/2 grains? i really can not afford to work up by 1/10ths of a grain. the cost of bullets would break me very rapidly. especially since now i am going to have to do this for every rifle i own. sometimes i wonder if it all is worth it!?!:banghead::banghead:

    Since you need to crimp on the cannelure you can throw out adjusting OAL at least. IMO 30-30 is not the easiest cartridge to reload since the brass is thin and it's long neck makes producing concentric cartridges difficult.
    Moving around 1/10 grain isn't going to change much. 1/2g increments should work fine to start with. Maybe you can tell us more about what powder primer and charge weights you've tried.
    This article has some fine tuning tips along with some basic accuracy hints:

    moooose102...Is that for a lever gun? If so...Try 32 grains of W-748 with a 170 grain Speer Hot Core bullet. Or look at a powder charge of W-748 near maximum (but not maximum) with a Speer 150 grain Hot Core FN. I'm getting 1 5/8" three shot spread at 100 yards from an old (1949) Winchester Mod 94.

    i have imr 3031, imr 4198 and reloader 15 (i have more, but it isnt suited for the 30-30). i used 30.0 grains of imr 3031 with 150 grain remington core locts round nose bullets, cci lg rifle primers, rp brass. out of a mid 70's glenfield (marlin) lever gun (microgroove barrel) about 4" groups at 150 yards. not terrible, but certainly nothing to write home about either. the winchester 150 hp's were averageing 2.5-2.75" groups. which is better, but still not great. the barrel was clean just prior to shooting and i am certain there was no copper in the bore. i had a problem with that a while back, and now i am a freak about it. maybe it isnt possible to improve on the factory rounds, but mine need some help.

    I'm afraid that is about all you are going to get out of that micro-groove barrel.

    I wouldn't have a clue as to how good my Ol' Jack Handle would do out to 150 yards. If I feel I'll be shooting to that range or better I take the .30-06

    Your accuracy is very good at 150 yds. I like IMR 4895 powder in my 30WCF .

    I'm loading a 125 grain Sierra flat nosed hollow pint with 31.5 grains of H322 and I am getting a 1- 1 1/2" group at 100 almost anyday. Usually I am resting on sandbags on the hood of my truck or laying on the groudn with sandbags. If I went to a higher magnification scope I could probably close thar group down some but for what I am using the gun for the low profile straight 3 power is fine.

    I read about a 1" 5 shot 100 yard group ~15 years ago on user groups [on rec.guns before there were gun forums on the WWW].

    I was getting 6" groups at the time, and so began my 5 year quest.

    Here is some stuff I learned:

    I spent a lot of time and money trying to find a 30-30 load that shot as good as the factory Winchester 150gr loads. I finally gave up. I shoot my 94 so seldom now that I just use the off-the-shelf stuff now. It's the only caliber (besides 22LR and 22WMR) that I don't load for.
