    Summer 2009 THR hunting rifle match

    I deem this my hunting rifle match. This match is for any CENTERFIRE rifle that doesn't disqualify due to the the below guidelines, even if you don't actually hunt with said rifle. As an added bonus it should be good practice for that old game getter what with fall approaching fast.

    Exclusions
    1. Must weigh under 10lbs as rated by the mfgr
    2. No scopes over 12x magnification (scoped class)
    3. Cannot qualify for CMP service or as issued rifle competition
    any one of these disqualifies a rifle for the purposes of this match
    4. No FMJ or match ammunition, all bullets used must be either cast lead or expanding as per the manufacturer

    Now I realize that some of you may hunt with rifles that fall outside these rules but please understand that I have to draw the line somewhere to keep this from becoming a precision match rifle shoot, read $$$$.

    Unlike like the previous match there will now be 3 classes tied to bore size.
    small bore which is up to but no larger than 6mm/.244"
    .257 to .338 for the medium bore
    and .348" up for the big bore guys

    Inside these classes will be the familiar 50yds irons, 100yds scoped subdivisions




    The Rules

    You will fire 5 shots onto the approved target set at a range of 50 or 100yds depending on the sighting system used, ANY shooting position is allowed. Groups will be scored by a smallest size wins for all 5 shots

    The target used will be a "paper" plate, you can paint, color or put any dots you wish inside this target but the "group" shot must be on this plate. For those of you who's range rule prohibit the use of a plate see this post

    you will shoot 5 shots onto the plates adhering to the rules outlined above. When you have a target you're satisfied with you need to make note on the target the following information

    username
    group size
    firearm & sighting system including scope specs
    ammunition
    date fired
    class and subdivision

    then take a pic of it and post it here, if you would please post a pic of the rifle used as well.

    You may submit as many targets as you wish provided one of three things
    1. the new group betters the last (leave the old pic up though)
    2. the new group is for a different class
    3. It was shot with another firearm
    targets can not be recycled from a previous match;)

    this match has a cutoff date of October 1st


    Scoring and classifications
    The three leader boards will represent the current overall match leaders in each caliber subdivision. At the end of the match any action type that has more than one submission will be broken down further into first, second and or third place. This way levergun guys still have a reason to shoot against bolt actions so on and so forth.

    I like it & I'm in if this one is going to run for two months as suggested in last months thread. Also gives me the chance to qualify in a couple of different classes.
    I won't be able to shoot 'till next month since our long range area is a dove flyway and we are shutting down this month to let the critters settle down in preparation for a youth dove hunt on opening day.
    I'll be kept busy this month building new target stands for the range.

    krochus, I'm definitely in this match (100 yards scoped only) with the following rifles, bullets and powder.

    Medium bore

    7mm-08, Savage 16 Weather Warrior, Hornady 139gr SST Interlock, IMR 4895
    300 WSM, Remington 700 Alaskan Ti, Hornady 150gr SST Interlock, Reloder 19

    Big bore

    .45-70, Marlin XLR, Remington 405gr JSP, VV N130 (maybe N120)
    .45-70, Marlin Guide Gun, Remington 405gr JSP, VV N130 (maybe N120)

    This match will put the FUN in FUNctional since I need to work up hunting loads for the Savage and the Remington as well as continue working up loads for the Marlins.

    :)

    I'm anxious to see your two medium bore rifles pitted against one another

    That's what I'm hopin. If you need to sight in anyhow why not do it on a paper plate and join in the fun

    I'll shoot the Rifles I shot in the last match plus I hope to have my rem7400 weathermaster sprung from layaway in a couple weeks. alas I own neither a big bore or a small bore that can compete

    The Remington is VERY accurate with 168gr SMK bullets and Reloder 22 but I'm expecting good things from the Savage too. I have no idea how either will do with the Hornady SSTs but that's the whole point.

    I like the fact that you specified hunting bullets only ... I'll be including some reloads and bullets in my photos ... as evidence. :)

    What caliber is your 7600? I see that they're offered in .270 Win and .30-06. I imagine you opted for the .30-06 but either way ... I'm interested to see what that rifle is capable of.

    :)

    My rifle is the semiauto 7400 chambered for 30/06. It's also one of the cool and kinda rare weathermasters, baciclly a rifle given the 870 marine magnum treatment

    Way to go, Krochus! Both on your great shooting, and on organizing this match! :)

    Here’s a target I shot a couple of days ago. As far as I can tell, the rifle & scope fall within the rules. Krochus will straighten me out if not.

    Group Size: 0.410”
    Rifle: Savage Model 12 FV Varmint Series, .243 Win
    Weight 8.75 lbs (from Savage’s 2008 brochure)
    Scope: Leupold 3-9 x 40 VX-I
    Ammo: Handload, 58 gr. Hornady V-Max, IMR 3031 powder, approx. 3300 fps
    Date: 7 Aug 2009
    Class: Small bore, 100 yd scoped
    Position: Sandbags and a bench.

    The rifle is stock, “out-of-the-box”. It has an Accu-Trigger, but it was produced before the Accu-Stock. I just checked the Savage website, and it looks like they no longer produce this model in .243 Win. That’s unfortunate. :(

    I’ve tried several different bullet/powder combos so far, and it’s not too hard to find a combo that it likes to shoot under 1 MOA. But it seems to LOVE the 58 gr Hornady V-Max and IMR 3031. :D I’m not comfortable posting specific load data on the internet, but I will say that this load is near the lower end of published load data for this bullet/powder combo. Not the very lowest, but close to it. I’ve chronographed it at about 3300 fps, so if you have loading manuals, you can figure it out.

    By the way, it can easily push this bullet at around 3800 fps using published load data, and the results on a 1 gallon plastic milk jug full of water are SPECTACULAR!! :what:

    Safe and Happy Shooting!

    Good shooting Mustang!
    I'm glad that's a different class than I'll be shooting. :)

    Krochus, I'm really going to have to tighten up the groups with my Colombian to better your 1891. :banghead:
    That 7.65x53mm is an accurate round.

    No doubt! I hope this unusually high bar doesn't discourage other participants, Congradulations!

    Well I'm off to the range to take that weathermaster for a spin

    Boy when I said this I never thought this would apply to me as well in the medium bore class:eek: Patience, carefull heat control and lots of dumb luck really paid off today. I figure the least I can do is share my secret


    I fired one fouling shot at the backstop to get the rife up from room temp to close ambient temp (warm) fired the first shot of my group and followed up with the other four at 5 minute intervals

    the hole towards the top of the plate is from a staple

    please don't hate me:eek:

    unfortunately I got the 7400 hot during sight in and as we all know a hot 7400 isn't a happy 7400 in terms of accuracy and at 90 degrees+ I never could get the heat back down to shoot serious groups. I'll try again another day.

    Only if you've been taking lessons from Otrman :(... but I'll get over it.
    I know what you guys are doing. You're getting the best ones out there so you can sit back for the next 7 weeks & watch the rest of us scrap for a place on the leaderboard ;), but the Greyhounds do need a rabbit to chase!
    Fantastic shooting, both of you. Congratulations!:)

    Krochus,
    I hunt with my 1942 Mosin 91/30 that was never a "sniper" rifle. It has a BSA "Contender" 4-12 X 40mm scope on an AdvancedRifleParts mount and I changed the bolt body to one with a turned down handle. I've also re-crowned the barrel to get rid of some serious dings.

    Since it doesn't qualify for CMP and "as issued" rifle matches, and I use it for hunting, is it allowed in this one?

    I also have a much modified Mosin M44 "scout" rifle that might qualify too.

    Ammunition is handloaded using the Hornady 150 grain flat base spire (soft point) using New PrviPartizan brass & Alliant Reloader-15 powder.

    Our indoor range will allow paper plates if they are stapled onto one of their special targets (flip overs to keep the target area low enough so you don't get too high on the backstop.)

    As long as expanding ammo is used your 91/30 qualifies for this match at around 8.75 lbs

    Thanks Krochus,
    Just got back from the range and found your message. Here's a couple of photos of the target with the calipers on the group.

    Center to center at the smallest, .411" and the widest part .484". Not quite as good as yours but pretty dang good for a rifle that was made the same year I was born (1942).

    Neatest thing - another guy was down there (a Remchesterby type) with his Remington 700 in .308. He was grouping 1" to 1.5" at 100 yards. After I showed him my group, he was grumbling a bit, and so I let him shoot my rifle. He put 3 rounds in .5" all touching and it beat the heck out of his shoulder (no wussy pad on the 91/30). As we were leaving the range, he was going on about how much more accurate that old 100 buck Mosin was compared to his 800 buck Remmy with the 200 buck Leupold scope.

    My scope is a 100 buck BSA Contender and the mount cost me 90 so I have under $300 in the gun. On a fixed retirement income, every penny counts these days.

    Do me a favor and measure your group across it's widest extreme points outside to outside. This is the measurment I need to make an accurate placement of your submission

    That comes out to .695", but I always thought groups were measured center to center. That is the way the NRA categorizes them. It's your match though, and the widest outside to outside is .695 That actually penalizes those who use larger diameter bullets though.

    Oh yes, 7.62X54R ballistically equivalent of the 30-06 so it comes out as medium bore. I forgot to mark that on the targets.

    They are but on a one hole group you measure to the grease ring at the two extreme points, then you take and subtract one bullet diameter from this measurment giving you the group size center to center irregardless of caliber and in a more accurate manner than using mkI eyeball to estimate the center of a couple of bullet holes

    .695-.312=0.383":eek:

    So see your group is even better than you thought it was

    I can't get it to work right on my computer though:banghead: but from what little bit it worked it seemed to be more than accurate enough, if others want to use it I'm fine with it

    You're absolutely right. Didn't know what method you were using to determine it. I have a piece of software called OnTarget that will calculate group size from a target picture if you give it a reference size (mark the edges of the opening of the caliper) and tell it what the caliper read and then tell it the bullet size. Now, it gives you a circle with a crosshair in it and you mark the bullet holes using the precision caliper. It then calculates all sorts of neat info. I didn't use that when I initially posted the target info, but running it now, I get exactly the same numbers you did.

    BTW, it will run on my computer and is really easy to use.

    Thanks!

    Fun shoot and I'll definitely enter others.

    Jim
