    Milling mag slot HBR

    So I've got a singleshot Time Precision action I'd like to make HBR legal for IBS/NBRSA

    If I mill a slot in the bottom how big does it have to be for it to be legal?

    Al, for NBRSA, it needs to be large enough (length/width) to allow passage of a loaded round, held parallel to the center-line of the action. The magazine need not be functional (how carzy is that? ), as in capable of actually feeding a loaded-round: the "follower"/loading ramp cannot be fastened to either the action, or, the stock. I cannot recall the IBS rule. Keep 'em ON the X! RG

    BTW Randy, once't I gotcha' on the phone....... back in the day the rules read "triggers must be "hunting like" triggers. Aftermarket are allowed, but no 2oz triggers"

    How is this being interpreted this day?

    Al, the current rule book makes no mention of triggers.

    Go to the on line Rule Book. Section eleven covers everything.

    So it looks like NBRSA has also done away with the "30-30 capacity" rule........ or did NBRSA never have that?

    NBRSA Hunter Bench Rest allows 30BR?

    I'm so confused.... I've got 3 old "Hunter Bench Rest" projects I'm resurrecting because I'm getting to where I can travel to some score matches. Go, one in 308-.200, one in shortened 300 Savage and one in 30X47L with several barrels. I killed 'em off 10yrs ago when HBR went titsup in this area.

    I thought true HBR was back but if 30BR is allowed then I need to just bite the bullet and start over

    According to the rulebook for IBS the following things seem different than NBRSA;
    -30-30 capacity
    -magazine to hold 2 rds (don't know if "hold" means keep 'em down)


    They too have done away with the trigger limitation compared to my older rulebook. NO trigger restrictions as I read it.



    And BTW...... in either case, if I DO set the mag up to feed a round, can I? CAN I shoot repeater? And does the extra round(s) count against my weight?

    I've never been to a HBR Match

    Magazine feeding has always been and remains illegal. The "old" rules required, "capable of holding AND feeding two rounds" - that went away around the mid-90s. Still, we must have the slot - never have understood that!

    For Hunter Class, NBRSA removed both [minimum] caliber and case capacity restrictions about five years ago, for a " 3 year trial period" - after two years, this change, was voted into permanency beginning 2016. So, yes, just about any cartridge is legal - I believe the top end limit remains .45 Cal. - I once shot beside a fellow using a .460 Wby. Mag!

    Going back, to, at least, 1992 (NBRSA), there have been no trigger restrictions, including the, "operable safety", requirement.

    I'm pretty rusty on the equipment rules . . . all of my (Hunter Class) stuff would be legal under all of the rules (IBS/NBRSA) going back to 1990 or so. The salient features remain: 10 Lb. weight limit; 6X scope limit (or, variable set and taped at 6x); 2.25" fore-end width. RG

    The action also needs to comply with the rules for width (1.400 wide and 10.25 long). -Al

    It does......

    I just don't want to tear up a good action only to find I've buggered it up for one class or another.

    I'm considering opening it up for an AI (CIP?) style mag Justin Case!
