Since 2011 I have continued to shoot small bore prone, I have upgraded my rifle to a 1976 version:
As my round and match count has increased, I have been using lighter triggers. I believe the rifle is set up for a 4 ounce first stage and an 8 ounce second stage trigger. I am of the opinion that a light trigger is an advantage as you move the rifle less upon trigger release. You can shoot exceptional scores with heavier triggers, you just have to pay more attention to your hand and finger movements.
I rarely shoot ten X cleans at 100 yards. These are exceptional match targets for me:
For me to shoot a 10X clean (the X ring is about ¾”) it has to be a really good day. Twenty two bullets are so wind sensitive that winds can’t be nasty gusty or swirling. I need enough sunlight to read the mirage. The slightest wind increase will blow bullets out to the nine ring. If the wind is consistent and predictable I can really lay them in the X ring.
You still can shoot exceptionally well with vintage 22 LR’s such as the Remington M37. Unless the M37 has an aftermarket trigger, the pull weight is no less than 3.0 pounds. The stock follows the match rules of the period, which were written by the military, so that a small bore rifle stock was as close in configuration to a type C M1903 or Garand stock as possible. This M37was owned by Larry Moore, Larry is on the front of this
http://www.gunsmagazine.com/1956issues/G1256.pdf Dec 1956 Guns Magazine. The Club President shot long range with Larry Moore and was able to buy this M37 from Larry’s estate. It has an Eric Johnson barrel, which was first class in its day. The President shot in a local 22 LR prone match, but he decided to shoot “F Class”, that is with a rest. These are two of his 100 yard bulls.
For practice, I still drag out vintage blunderbusses, this H &R M12 is one I have been having fun shooting.
Recently I shot this target in practice, prone with a sling at 100 yards.Still, the horrible stock configuration and heavy (3 pound) trigger work against best consistency. With a better stock and trigger this would be a very competitive rifle.
Having enough 22 LR’s to compare, I can say that matching the ammunition to the rifle is critical for best accuracy. As a general rule, the more expensive ammunition is more consistent. However, I have shot some amazing groups with lower priced, Eley Club, RWS Target, SK Match plus. Rifles are picky, for example, the H&R M12 shoots my lot of Club very well, pukes on RWS Target. RWS Target shoots exceptionally well in my BSA Martini. I cannot explain it, perhaps it is due to randomness, but I really think, you have to test particular lots of ammunition in the rifle, and which lot shoots best in one rifle will not necessarily shoot best in another.
For reference, I copied these numbers from the Eley Presentation given at the 2014 Small Bore Prone National Matches at Elkhart IN 2014
Factory Range Ammunition Test results
Anschutz M1913 serial number 3,125, 490
Red Box Tennex

Walther rifle
Same lot Red Box Tennex

Eley has its own in door range, is not shooting these rounds outside where the winds can blow the bullets around.
