Front sled dimensions for F open

[Shawnba67]

I saw in the rule book that foreend may not be more than 3" wide. I did not find any info on the sled.
1. So I assume it counts as fore end?

I also see most for sale are about 6" long.

2. Is there a rule on how long they can be?
or is 6" just "about right".

I ask because I'm making one for myself, I have plenty of room in the Weight dept. The piece I picked up is about 7" long and if i dont need to cut it I will were out my arm lifting cold begerages instead of sawing.
Thanks

Must be no wider than 76mm (2.99"). Has to be designed to lift straight up out of the front bag; it cannot have an inverse taper to 'dovetail' in the bag. No restriction on length that I note.

Careful...the NRA rule reads, "The area of contact between the front bag and the rifle’s fore-end will not exceed 76mm x 76mm (2.99 inches x 2.99 inches)." 76 mm = 2.992117". Also allow for stock tape thickness if you are going to use it on your forend.

Does that include the area of the side touching. I see stocks with more and more side contact.

Would this be set by the bag you were using? This is a real question, the contact with the bag cant be bigger than the bag correct? Or am I understanding it incorrectly?

Yes, as it appears to be the rule.

The change comes from the ICFRA rules, I don't think the intent was to count side contact but rather just the bottom of the stock. Anyone with any knowledge of FC history would not interpreter it any other way. Time for another change? http://rulebooks.nra.org/documents/pdf/compete/RuleBooks/HPR/2018-hpr-book.pdf

3.4.1 Rifle Rests - (a) F-Class Open Rifle (F-O) - The F-Open rifle may be supported by a front rest bag, which may be fully adjustable for position but may not provide a positive mechanical method for returning the rifle to itts prior point of aim from the previous shot. The rest may not mechanically capture the fore-end of the rifle in such a way that does not allow the rifle to be lifted directly up from the rest or to be placed directly down into the rest. Any rest which captures the fore-end of the rifle and that will not allow for the rifle to be lifted directly up from the rest shall be considered to be an attachment. The area of contact between the front bag and the rifle’s fore-end will not exceed 76mm x 76mm (2.99 inches x 2.99 inches). The F-Open front rest may be employed for either the rifle’s fore-end or for the shooter’s forward hand. If attached, clamped or held onto the rifle in any way, a front rest must be included in the rifle’s overall weight. The front rest may have up to three “feet”. Each “foot” may terminate in a spike, which may be pressed into the ground by up to 50mm (about 2”), provided this causes no significant permanent harm or damage to the firing

I am still puzzled on what 2.99x2.99 means. Like a previous post said just the bottom surface, or total surface, sides and bottom. 2.99x2.99=8.94 total square inches??? If someone from the NRA could chime in and give us the real answer it would be appreciated. Also in L Bart's post it states must be able to be put back in the front rest. Sand moves and once you remove the rifle sometimes the sand moves enough so the rifle needs to be wiggled to get back in. Is this illegal.

This means that the foreend slide cannot be any wider than 2.99" and that the bag that it rides on cannot be any longer than 2.99". Thereby limiting the total contact area to not more than 2.99"x2.99"=8.94". It does not limit the length of the foreend slide under the rifle.

Seems like technically you could have a longer bag if your forearm/bag rider/sled was limited to 3 " of contact length. Lot of trouble just to be contrarian, though

 

[kzin]

There is no indication the rule is meant to completely revamp >90% of current equipment so clearly the sides don't count.

If the sides are tight enough to count as contact they will fail the lift test anyway.

Now if you used a v shaped bag and stock the 'sides' would have to count.

The bag can be 76mm w X 76mm d X 25 mm H. The stock 76mm w by any length by any height. With the side of the stock higher than the bag and at right angles to the forend base you can not get caught on the lift out. Don't use a flat stock, rails are the way to go. The size only has to be in one place at a time not all places all the time.
