Well today I loaded for "load development" Best current group avg, Seating depth powder charge increased by 3 tenths from starting to what I thought was reasonable. I then loaded the truck and headed out to the range: only to find it closed for a Mountain man event. I guess what I learned today is to check the calender before driving.

Went to the range today not great conditions. the Hiviz Bag Rider custom whittled seemed to be a success. Even so there is a learning curve. Brought a long the Chronograph.It seems that I am stuck with 1/2" groups Which I can live with 85 gr @2775 are not exactly what i was hopping for. Not to mention 5 shot groups that look like this are ridiculous Next gizmo will will be a spring loaded hand guard stop for the midway front rest. Thinking that a spring compressed a small distance will be more consistnet the judging how hard I am pushing on a stop. Thanks Paul

Looks good but you need a shinier penny.

Well after today's range session I am going to have to build a rifle that shoots to it's potential instead of mine. today was light rain light to moderate wind. and poor shooting. On the way home a dry freshly graded road washed out from a distant rain for an 18 mile detour on a 12 mile drive. but you have got to love it when you go from vertical strings to horizontal strings the next group. previously this gun averaged 1/2" groups today it only achieved 1 and would have an avg of about 1.25"s 250% is a big change. How could this happen, I do not lack for gadgets.
Paul
Please don't let this rant distract you from any thing worth while.

The barrel shoots as shown by your previous session. A componet change or even atmospherics may be in play. New box of bullets? There is also the bugaboo that sometimes the dragon wins no matter how hard we try.

After studying all the groups it must have been me in archery; I would call it chasing the bull. Some days that is the best I can do. Maybe next time.

Does not seem to be a lot of shooting going on. So I will have to do it myself tomorrow. It got cold last night. and the 5/8" of rain put September above the last several years for rain fall 4&1/2" at my house. the wind has come in behind the front so it may be interesting. Hope fully lessons and loads will coincide, and I will shoot like I think I shoot. instead of how it usually turns out.

Well another day at the range.Shooting 748 this time as it can be used in the 243LBC. Unfortunately I got mixed reviews on my self and the rifle. The sharps and trapdoor Springfield shooters called it a space gun The targets from today where shot through the chronograph. of course the worst group gave the best velocities. then there was the usual frustration Lower right col bore shot next 3 in the 1/2" spot #4 just tried to hard. not to bad velocity high 2800's 9/16" mid 2900s I will work with this Seating depth and such. Maybe next week I will load enough to get some answers. No longer tracking avg group size as today's worst at 1&3/32nds plus the 7/8" group would take to long to overcome. Paul

It may well be you have a 1/2" gun. There are limitations to the platform that we just can't get around. We have so far exceeded the original operational parameters and expectations as to be mind boggling. Bug holes are nice but they rarely get produced CONSISTENTLY by an AR. We read time after time about the guys that shoot groups of 0.375 or so at 200 yards yet we never see TWO of those on a piece of paper or even on TWO pieces of paper. Pretty much Bull Squirt when guys start bandying those about. I shoot the odd screamer at 100 yards and post it up but I also post up the occasional whimper. I tend more to the happy purr groups in the 0.5 to 0.6 MOA range. If I get that with a non-bull barrel AR I am pleased. I strive for a sub-0.5 MOA in the guns I intend to shoot at truly long range of 500+ but in my varmint guns one at 0.6 will kill PD's way out yonder all day long. Reading the wind for those tiny groups is my biggest bugaboo. Some guns shooting high BC bullets at a good pace can shoot through a shift and make me look good but some days as I say, the dragon wins, winds??? I can make 'em talk on my good days but there is that rare occasion where the shooter is better than the equipment. I have one particular rifle that I put right on 800 rounds, that would be 160 groups, down range with shooting around 80 different loads of bullet/powder combinations. Looking at my records I see about THREE that were truly sub-MOA. THREE. The BEST ten shot groups were shot with a bullet too heavy for caliber with a powder charge I guesstimated at. A paper killer it was but I wouldn't take it after something that was warm. This one turned in velocities on par with a similar cartridge but the other one was a straight factory load this one took necking down and case turning with a huge amount of effort. It shot worse across the board and no faster than a standard loading with 1/10 of the work. Basically after spending around $250.00 on components, barrels are the CHEAP part, I pulled that barrel and went with something that was tad more mainstream. I was much happier but the PD's were the worse for wear. Keep us posted on your progress as any one that contributes to the board just expands our experience and knowledge base. Greg

There is only so much I have control of. I still can not find any 8028 so I am grasping at every straw that drifts by Today I shot five different loads. At 100 yds my .243W does not notice the wind the .243LBC seems to, just that little bit slower. Today during a shift West wind to East the first three into .231" the wind opened it 3/8" on each side. Variable @7 to 15 mph. # shot groups might be a better deal do to the shorter time . but I usually ind up chasing a lot more moments of brilliance than I do with 5 Shot groups. Any way today's shooting left me with a bunch of sub moa groups and even a couple I feel pretty good about. So I will load up a bunch of rounds and start just shooting it. I think my shooting improves faster when I go to position shooting practice so off to the pellet trap for me .

Looks like you have proven that the gun can shoot. Look at 3rd Generation for reloading supplies, and no I don't have a link, and you can MO the stuff. They have good prices and four pounds will cover the HAZMAT. I recommend buying 8 pound jugs when you can and every bullet you can squeze in. Having enough componets to shoot for two solid years is a great comfort. I know it was for me.
Greg
PS: Buy PRIMERS too! LOL

Well until this week they did not have it in stock. I spent the last 2 and a half weeks checking between here and North Dakota for it. None available any where, but what are vacations for. Got home found it locally yesterday. I bought it in the 1# can to try loaded last night and started shooting today. shot 3 rounds into the same hole the had a feeding problem. any way for a first try I was impressed. All of my load development has centered around the sierra 1530 85gr. HPBT today I was playing with Hornady 87gr. Vmax's which gave me a new problem. Their less round profile means that seating them 0.010"s off the lands load at mag length every thing works well single loading. put four in a magazine and the won't allow it to lock up. it appears that this due to the bullet being jammed into the locking lugs and then into the chamber roof prior to clearing the magazine. The Sierra bullet loads to about 0.080" shorter and does not have this problem. Once the above has occurred the round will not chamber without the forward assist. So I will start pushing the length back until they feed from a magazine. As the are not noticeably cheaper it is no real loss. except being pointier the ballistics would seem to favor them. Well for now that's all I will post an update next week. The Capitalists say I must work the next few days. I could consider retirement at some point if we had a federal Loadaide type program.
Enjoy your weekend Paul

I hate to reply to my own posts but it seems my thread does not interest many. Today was a bright sunny warm pleasant day so of course I was grand fathering with no car seat until 1/2hour left allowable shooting time on the range. Changes made Added a level to my scope. This really helped with the shape of groups. All bullets where seated deeper. Since initial function testing I have not loaded with a magazine at the bench (shooting). So when I thought I had a load; it did not fully chamber from the bolt release alone. The HDY load is now much shorter 0.110" it scraped in with a sub 1/2moa group 1" at 191yards. The sierra 1530's are only 0.01" shorter (They started about 0.09" shorter due to bullet the difference in ogive) The sierras shot about 0.985". Only had time to shoot 2 groups.
Wish you all good shooting Paul

Wish you all good shooting Paul I suspoecet I was out of town on the previous post and flat missed it. I apologize for that. Now doing what I do best...lets spend YOUR money. I sugest you grab up a Sinclair tool for measuring lenght to lands. It takes about 2 minutes to do one if you are real slow. It will give you dead nuts the measurments you need. I just checked my inventory and will look at the Sierra and the Honaday bullets in my barrels. Not exact but maybe give you a ball park figure to try. I've got three of them so we should have some numbers to look at. Sounds like you are no slouch a tthe trigger congatulatons and keep up the postings. Greg
