i like the way my 15.5 lb dasher shoots and handles.( lite gun is under 17 lbs for 600/1000 br)
i have a 20lb 300 win mag for heavy gun, but was thinking of building a heavy
dasher ?
stupid ?
over kill ??
thinking a mini version of the big guns...something that just sits there
but shoots well

thanks
mike
 
I know 22lb dashers shoot very well. Get too heavy tho and if its not on rails so it can move with recoil it may not work well. A dasher is a 600yd gun IMO. For heavy gun 1k i think you need the extreme bc of a big fast magnum

I wouldn't tell that to Mark King. He did as much winning as anybody last year or two with his braked 100 pound heavy gun that would shoot 10 shots in 13 seconds or less. He never adjusted or pushed the gun back. It never moved more then an 1/4 inch or less per shot. The gun consistently shot 4 to 5 inch 10 shot groups at 1000 yard. He also won the 2 gun shooting with his 17 pound Dasher and that 100 pound rig. Matt
 
If it works like our old br guns we called cruisers you reckon he could shrink that group up a tad if it weighed say 75lbs? 55lbs?
 
there is a guy at the nationals with a large dasher....35 plus pounds
1.45' dia bbl, large action,
i can get a 1.45 in my lathe...hmmmmmmm
 
just too big

Keep in mind the law of diminishing returns. Bigger is not better. A lot of years ago Dan Lilja and I did testing on rail gun barrels of a lot of calibers. After 1.450 accuracy started to diminish. It was a little hard to determine but 1.350 to 1.45 seems to be best. This was shot with a stainless steel rail I have with a 97 lb base and a 60 lb top. It has a hydrologic ram that catches the recoil after 2.5 inches. A gun seems to require some rearward motion for the gun to function at its peak.
 
Exactly. Its all been done before. Even ballistics testing labs use return to battery guns. I have tested guns in a barrel block mounted to an unmovable table. Shot horrible groups indoors but the same barreled action on my rail gun went right on into zeros same load sitting on the same table.
 
Most of the heavy guns in 1000 yard BR are 60 plus pounds with 1.450 Diameter barrels glued into a barrel block. They shoot better then the 17 pound light guns and records and aggregates show this. Even the guys that built 22 to 28 pound guns with heavier barrels shoot better. The Dasher holds a lot of the 600 and 1000 yard records. That heavy gun Dasher that weighed 100 pounds won many aggregates and helped guide him to the 2012 two gun at the IBS nationals and the 2014 two gun at Williamsport, The gun just really shoots and the groups and clusters are as good as any at 1000 yards. I wouldn't build one that heavy but I would build one around 35 to 50 pounds for a Dasher. Heavier for a 300 WSM at 60 plus pounds. These are just facts. The gun has consistently won over the last 8 years or so, He sold it to another guy and the guy shoot a low 4 inch the only time he shot it this year. He also won the group shoot off but I don't remember what the group was or how much he won by. In our testing heavier was always better but I believe you can reach a point of no return. Guys have experimented by bolting steel or tungsten weights on the aluminum stocks. Most of the heavy guns have used 1.450 Diameter barrels and it seems to do best. I have seen a couple of 2 inch barrels shoot well but I believe a 1.450 is better. Matt
 
1.450 is best for a ppc. I figure it is good enough for others too. It would be hard to determine where that point is for excess on weight
 
My HV-Gun is a 54-lb 6Dasher, in a Shehane Maxi-Tracker, with the action bolted in with 1.250" floating barrels instead of 1.450" blocked in barrels. I played with the weight from down around 40-lbs up to +60-lbs, settling at 54-lbs and is where it balances and tracks the best for me. If I had it to do over again, I would have made it weigh more yet and I don't see myself ever going back to lighter versions.
And will say to those who have say like a 25-lb HV: except for carrying them to line, betting you would like a 55-pounder or heavier better... or so is my experience.

My heavy gun is a 80 pound 300 WSM bolted in a Mark King aluminum stock. It has a 1.450 diameter barrel glued in a block. It is 6 inches wide in the front running on rails and the back is 2 inches wide with a double rail. The gun was about 65 pounds but on recoil the back wanted to not track. I replace the aluminum butt piece with a stainless piece and now it tracks. The gun really shoots good and it shot 10 shots in 2.815 inches at 1000 yards. The gun has done really well over the last 14 years. It has won a bit of wood and prizes over the years. Matt
 
i think i am too old to carry an 80 lb rifle.....
but i do like the 300 wsm.

Mike -

If I was to build a 300-WSM HV-Gun, it would be heavier then my 54-lb 6Dasher, and +80-lbs like Matt's sounds righteous to me from my experience.
The 6Dasher moves/recoils my 54-lb about 3", and my bags aren't even the "slick" ones......
