just got in from a short session @ 200yds. decided to try one of earnhardts power loads 90.0 gns i3031/327mh loose fit speeds-2759,34,20 not bad but did not like the es but partial sunlight was in consideration also.... so last week I shot a decent 3 shot group(1.6")70.0gn i4198/327mh @ 200yds so after some thought just upped this load to 73.0gns/i4198 in which I am considering max territory for this gun. what a surprise a .477grp @ 200yds this is a wallet group & I will start this load going long soon if it keeps panning out/fps 2729,34,20 on the .477grp speeds were nowhere near earnhardts(approx. 200 fps less) & I think it is some due to lrmp & my much looser bullet fit in which this gun seems to especially like. some notes- prior 275mh great groups started opening up due to what I think was temperature related. with the parker bullet shortage I need to keep bullets downrange to a minimum until they are more available. disclaimer- these loads appeared safe in my gun but maybe not in others..... all were shot smooth die sized..

Great group would be an understatement!!! Care to elaborate on the " temp related" part?
Always look forward to your reports and outstanding trigger pullin.

Very nice shooting, 325 MH at mid 2700ft/sec. is good also. Looks like it should be ready for the whitetails.

Deadeye: That is good shooting with the MH's. I would be interested to see how it does with say......the 300 FTX or SST? For comparison. (in view of the fact the MH's are in short supply) Richard

yes that gun is a shooter for sure, trigger puller is obviously doing his part as well...

Always look forward to your reports and outstanding trigger pullin. davew- may be all wet but seems every time we have a 10-15 deg temp drop my bore is slightly tighter. went to 2 mz matches & both times with a am. shots the bullet loaded slightly harder & had to make an adjustments/did not the evening before-it could be fouling but the jury is still out. just after posting this thread the gun was left on the bench for a couple of hours after a sighting adjust to go long. when returning to go @ 435yds I noticed the bore again was slightly tighter.(6 deg drop) this has not happened when it was warmer say around 75deg+,today started @ 62 deg down to 52 @ the long launching. my cold bore shots have consistently been in the group throughout my testing.the 3 shot @ 435 was 3" smooth sizing note- I have noticed w/ this brux bore & hankins die that the # of passes needs to be the same-example- 1 pass,2pass,3-4 pass the bullet fits differently. in the past with straight or duplex loads I can alter the fps reading approx. 80-100fps by just bullet/bore fit alone. I have ruled out plug orfice wear & copper fouling as both have been none. think I just got a touchy sizing bore but time will tell.

ok-temp/bullet/bore fit.... the gun has sit in the house for 4hrs @ approx. 70deg/just reloaded-same slightly tighter reloading resistance as when I left it this eve.//gotta be(powder) fouling imo. fwiw I strapped a small bungee w/note attached "loaded" for safety. thx guys for the positive comments Richard- I'm sure those will work fine as I have in the past but not enough time to play w/ those at this time...trying to get this ready for the upcoming deer season

Great shooting!!
The sizing problems you're seeing I've seen with the .451 MHs in my .458 guns as well. And also in my full form guns. Heat, copper fouling, powder fouling and even different powders will cause bullets to fit different. You have to loosen up your bullets a little with the dirty powders and tighten the bullets up with clean powders.
Who needs speed when your gun shoots like that!

I would feel good with that group at 50 yda. I know it says LRMP but I didn't know you had that system. What kind of gun? What are these matches like? Are you making a good living off your winnings?

I could buy Jeffs gun and still never shoot a group like that @ 200. he is one of the better shooters on the board for sure and with that rig the local bucks are in trouble..

Earnhardt- I was aware of that,have you had any barrels you had to keep adjusting no matter how many shots w/ same powder&bullet? thx all & yes I won both shoots,this last shoot I got an extra trophy! after the main shoot we always have 2$ 1 shot closest to center,usually goes until each is tired of losing their money,pic is deceiving as there is a compressed lump of $ there

one thing I have noticed with H-4198 powder and not so much with N-120. when the barrel sits for a while I believe the residue crystalizes/ hardens or whatever making it harder to get the bullet down. the reason I believe its more powder related than bore related is when you take a plug out immediately after firing the residue is damp and will smear easily, let it sit in the barrel for a while and it hardens.
the true way to find out would be to remove your plug and push a sized bullet down in warm temps and colder temps to see what the difference is. i will be shooting some N-120 in my new .45 and see what it does compared to 4198

Last year I swabbed a fouled barrel with an alcohol & dry patch before starting to shoot as an experiment. It wasn't as easy to load as it is after one shot, but you could tell a difference. Typically for hunting season, my hunting load gets loaded as soon as I am done checking zero. Do the same to check cold fouled bore shots.

Glad to see you're winning a few dollars with that rifle.... Everyone should bring their spending $ with them to the next shoot...... Jeff.

We had this thing in the artillery that was called "tube memory". We would see it very easily when we would change charges and the gun was set up with a chrony. Theroy was that when the tube was stressed it didn't immediatly come back to the same dimension before the stress or stress level was applied. If we were shooting charge 4GB and then switch to heavier charge 6WB the first round shot with the higher charge would be slower then consective shots. Then when we switched back to the lower charge the first shot would be faster. First shot out of the tube would be much like our fouler or cold shot, it would be out there and close but you couldn't put 100% on it being as accurate (maybe the correct term would be predictible) as the next round. We would do these missons called "single round adjust" where the cannon fires one round and then the observer would calculate the adjustment off that single round to hit the target. We had to work with the FDC not to give us a "cold" tube/gun. It would be like you going to the range with your rifle, firing a cold shot and then zeroing your rifle off the cold shot. Interesting reading fas.org/man/dod-101/sys/land/docs/fm6-40-ch3.htm

Glad to see you're winning a few dollars with that rifle.... Everyone should bring their spending $ with them to the next shoot...... Jeff. jeff that would be fun in addition to your great shoot,i have a fellow that loaded some ping pong balls with tannerite that have never been shot-would be very interesting especially out long for $ for fun. thx all for the fine comments but you have to believe me my pockets have been stripped quite a bit as we have some very good trigger pullers in my area,it was just my day finally! the above gun now is in testing w/ 327's @ 435yds & results are looking very good so far,would like to push it farther & will but we have bow hunters in the field with the pre-rut going on so testing is limited.

I'm gonna have to profess some ignorance here. What is this shooting tannerite business? I was in Utah a few weeks ago and I saw a sign at ths unofficial shooting area that said "no explosive targets". So is it an explosive you can pour into containers that detonates on impact? Did Deadeye invent it?

I think I mentioned this before but it bears repeating. I have shot tannerite and enjoyed doing so but be careful. Someone in this area put it in a old closed refrigerator(a lot as I understand) and it was shot. A piece or door handle or hinge blew off and hit a female photographer (I think over 100 yards away) and severely injured her hand. Multiple surgeries later and multiple troubles. Just a word of warning, do not go overboard on the same. A closed container can make it a bit bomb like.

Only chewing tobacco "skoal cans".. packages were used in Kentucky it was the cannon that had everybody's attention for safety,lol....
