If you were to make a gun to "clean" Manatee gongs...

What is the max renge? what is the average conditions? The 6mm Dasher is fun and hard to beat, Very easy to tune. The 6.5's start to show up better at longer ranges (600 yds +) and when you have more wind. The heavy calibers will take a toll on the shooter so number of rounds fired will start to creep in to the "Ideal" caliber. I was looking to build a "windy conditions" gun for mid range (600 yds). I'm shooting a 6 Dasher now. I found it would take a much larger cartridge to drop the wind effect very much. I was looking a 7mm such as 284, 7mm-06, 7mm Rem mag. I hunt with a 7mm Rem mag now using 168 Berger VLD's. The dasher is fun to shoot but a pain to make brass, I'm not sold on the Norma Dasher brass, I don't think it shoots better or as good as Lapua 6mm BR formed. My newest barrel is the 6mm X47L, so far it is not better than my dasher barrels, I'm shooting sub MOA @ 600 with it (10 shot groups) but only have shoot about 150 rounds working up the loads.

I have shot them for 12 years . The best combinations that won over that time .
Was 338 and 300 then 260 Ai rains a couple of years Then the 6 br The dasher has pretty much taken over . Accuracy trumps
BC. Gun weight and design doesn't matter
When you first start Every good shooting gun don't miss . The 3" at 1000 gets hit regularly . Conditions change very fast . Not only between shot but relays . One side of the range has total different conditions then the other . Most matches are won by The shooter correcting for the conditions And not move in the scope .
Dasher is still the case of choice Larry
 
A 338-408 or 375-408 Cheytacs. The wind drift on these are incredible. Something about a 300 grain Berger going 3200. Might be hard on gongs though. My buddies shoots 5 inch 5 shot groups at 1000 and his wind drift in hunting season at 1350 yards was 3 minutes and mine was 6 minutes. It was incredible. Matt

If it's unlimited, why mess around?
 
6BR, 6BRX, 6 Dasher shot about 4:00-5:00 AM with artificial light on the gong.
Only luck can overcome heavy mirage with funky breezes.

Exactly. A true heavy gun, you dont even need to look through the scope. That eliminates mirage chasing issues. Manatee winds get blown out of proportion they aint that bad at all. The mirage is the killer there for sure. Build a true heavy gun that will return to battery and you will have a real advantage. If your gonna do a real heavy might as well go with a wsm.
 
I had a shoot off for first there one time against a fella from Ft. Lauderdale. He was running a .340 Whetherby magnum 80# railgun. I was shooting my 7saum, first time out. My rifle was a Savage BVSS , 30" Shilen Select Match Harrell's radial brake, 180 JLK. The week before Ggmac screwed the barrel on at the Palm Beach county Sheriff's range and I did a little load development at 300 yards. He got lucky, he thought it was going to be an easy win. Coulda, woulda, if.... I'd of had the .300 Lapua I would have kicked his butt.
 
Charley Brown has a 80#. 300 WSM built by someone that shot in Pennsylvania . The wind moved his bullet beyond the post in the next bay . That is about 3'
The reason nobody has cleaned the 1000 is we never have conditions that will let the shooters do it .
Dasher still has the record . And a savage on top of that. lol Larry
 
There are two ranges you will try to clean at manatee. There is the 1,000 yard gong that has never been "cleaned". The 600 has been"cleaned" by many different rifles and calibers. If we get the work done all 600 shooting will begin this weekend on the back 16 bench range. I just measured out the target line for IBS paper and it is 602 yards from the front of the benches. The new 600 gong will now be 625 yards. We will only place steel right in front of the backstop, which is 629 yards.

So now the challenge is to be the first to "clean" the 625 gong and the first to clean the 1,000 yard gong. Charlie Brown did shoot that creature for a while. it sometimes shot well but often was still no better than other rifles. Sometimes, it was worse. My little 15 lb Stolle Dasher with a short-range benchrest stock has beaten it. Same with my "good" Dasher rifle. Weight makes it easier in theory but in practice we have not seen that.

This was the line for this past Saturday's 600 gong. Probably the last on the main range, it did not get cleaned.

Many brought the big guns to show-em how it's done. I tried my 22-250AI and failed big time. Conditions looked perfect for a "clean" The first round seemed to show that might happen. Round two and it all fell apart. One of the finest shooters (High Master) was one of many starting perfect and literally got nothing both second and third round. Think the overall winner hit 9. 8 was second and 6 third. All that equipment, experience and talent could not solve the impact change I saw from conditions changing between rounds.

My suggestion for the 1,000 would be a heavy 284. For the 625 gong now, a Dasher. For the 600 paper a 6BRAI. That Dasher speed just might be the first 1,000 clean as many shoot it. I, like a few others, have hit 13. Most of those high hits have been with Dasher maybe just because most use that. As of yet I have not seen a 6,5x47 do much. Never saw a successful Creedmore but have seen some decent 300 Win Mags.

Gongs are limited to 30 cal for obvious reasons. We have seen major damage to the gongs from non-competitors taking a crack at the larger gongs left up for practice. Those 338's and larger trash everything. We remove our target gongs at 600 after each shoot. The 1,000 ones stay up all the time. Come and practice.
 
Yea like its fair shooting on that line. Jim and I shot it back when it was 565 yds and Jim I think was on bench 29 and I was on bench 31. At that angle we were probably shoot 610 yds and at a 30 degree angle to the clay birds ( no gong back then). I shot the east end of the fence and had to switch to the west for my next shot. I was at such an angle that when my bullet hit dirt it looked like I had missed by 2 feet. If you don't have bench 3 or 4 you aren't in line and it only gets worse the farther away you get. Will the new range have a way to keep the target square to the shooter?
