I’ve been scratching my head ever since I got my stryker solution Sl390 back from warranty with lighter pull weight limbs and lost around 32 to 39 fps VS the original limbs. with The original limbs it was quoted 390 fps with 385 grain total weight bolts. I’m now shooting 358 fps with the factory supplied 390 grain bolt. Im sure it’s still plenty powerful and fast enough for my hunting needs. I started doing some looking for lighter bolts to gain some speed back. I found some killer instinct hyper velocity light bolts around 370 grains Total weight with a 100 grain point. I shoot 100 broad heads so I’d drop 20 grains. I only gained 7 fps from dropping to 390 grains from 413 so imo I’m guessing I’m only going to get to approximately 368 fps or so with 370 grains total bolt weight. Guessing just leave it alone and shoot the current 413 grain hunting bolts I have at 351 fps. I am sure it will be less stress my xbow limbs and my guess the deer won’t know the speed difference either. Decades ago I never weighted bolts. I did the other day. I can tell you with my old slow Horton Hunter xs the lightest bolt I use to shoot out of it was the one that flew the best and always seem to get pass-throughs and deer. it weighted 280 grains without a 100 grain field point. It seems like everybody here is worried about adding more bolt weight to gain kinetic energy. I’m sure that helps out when you’re shooting heavier boned game and trying to break bones or hitting tough stuff going through an animal. But to me within 25 grain difference between the xx75 Easton bolts I use to shoot i could never tell any difference. The lighter bolts did group more accurately. I understand if you’re going to shoot 100 grain added weight bolt(500 plus) for something heavier than a whitetail. But I only shoot deer. I have a hard enough time now pulling out a 390 to 413 grain bolt Out of my block target at 358 fps. With the original 390 fps limbs it buried my bolts about an inch deeper or so. If I used a lighter, faster, bolt with less kinetic energy that means less penetration on my Block target an easier pulling out?…I doubt it. My guess is a lighter,faster, bolt would work just fine, but I don’t want to stress out my crossbow limbs In the process. I used to shoot overdraw for years with super white short arrows with bone arrows and never had an issue. But my guess is if I dropped a 370 grains I’m still not gonna get anywhere near my 390 ft./s anyway so it’s probably defeating the purpose and only gaining a half inch of last drop at 40 yards? I’m guessing I’d be better off just to buy a faster crossbow. So should I try the 370 grain bolts out of my stryker and Horton or just stick to the heavier current bolts I have?
