My main Bench / Pron rests are :
#1- Henery Remple F Class bypod rest.
#2- Harrison short BR.
The Remple is about $350 Cnd funds / $280 is Usd. This rest could take you to the Nationals easy.
The Harrison Short BR is about $140 Cnd/ $110 ish Usd. Much less in costs, but it can take you pretty close to what the R can do. The vertical adjustments are limited on the Harrison, so I have a small container that hold $2 Loony coins that I stack in the container to shim the rifle level.
There is some adjustments on the Harrison BR rest, but the cup & coins fine tune level for the 700 to 1700m and beyond.
I use a hard packed bunny ear bag and force the back of the stock into it tight, dam tight between the bunny ears,,, the bag also has a 1/2" 6x6 steel plate glued to it so it stays in place.
I use the Remple for F Class matches, in the off season both rests travel with me for the 1000 to 1700m clay bank shoots.
If the rifle is anchored at the back as the shooters cheek and shooters hand pinky holds it in place, then I'm off to the races. My thumb with the lightes of pressure and no hand canting / manipulations.
My free hand raises and lowers the back of the rifle by squeezing the bag.
At 900M + just above the 10" V
1000m + at 14" above the V
1700m + at 24" above V.
That way my free hand needs a firm pressure to squeeze the rear bag firm. The tighter I squeeze the bag, the cross hairs get onto the V ring as it forces the back of the stock up.
The barrel tip and cross hairs drop down to aline.
Remember, hard solid firm rear bag with rear stock ramed tight between the bunny ears.
PS: Don't forget the scope level and watch which way your rifle tracks.
After the shot,,, the optics should fall back on the target.
Both bypods have their advantages.
The Remple is wide and stable, once the bubble is levelled, I pretty much shoot the whole string of 10 to 15 with no further adjustments,,, the negative to this rest is its full time wide and does not fold away to pack off to the bush for Harvesting critters.
The Harrison bypods cover that area.
I have 2 sets of the H,,, short for off season bush treks, the full adjustable medium / longs are for hunting season.
Light weight and easy to use.
Not as stable as the Remple,,, but not the worse either.
Keep your eyes open down there for the super light weight carbon fiber By-pods.
They are like the carbon fiber tent poles with the elastic band in the middle.
If I recall,,, the shooter can use just first legs in pron, 3 extensions for sitting, 4 for kneeling, and 5 or 6 for standing.
There made in the USA, and are dammed pricey up here in Canada.
I'm making my own custom set up here.
Hope that gives you some ideas.
I like to buy stuff that I can use for target to field,,, that way I get a chance wear it out. LOL
