I have a tikka forest 260 remington that I loaded some berger 130 vld hunting bullets for. Berger says with varget 33.5 to 37 grains max getting 2481 to 2703 fps. I got with 36.6 a speed of 2593 , i know their chart says they use 24 inch barrel and I have a 20 inch. My question is can I increase my speed safely , not much on pushing the limits but i see speeds of 2700 on this site can iI get there with shorter barrel . Second I noticed in write ups it says 300 plus yards for berger 130 vlds ,I get all my deer here 100 or less. will it not open right ?
