Draw length modules and how adjustment works
DeadLock binary cams with a rotating module in half inch increments. The FlipDisc flips the bow between Performance and Comfort draw cycles.
The published range is 25 to 30 in , which is 5 inches of total adjustment. That range is the single most important number on this page, because a bow set outside your correct draw length cannot be tuned into fitting. If the bow is at the extreme end of its range for you, look at a different model rather than living with it.
Three terms get used loosely and mean different things. A rotating module stays on the cam and is unbolted, turned to a new setting, and re-tightened, which you can do at home with a hex wrench. A module swap means buying a different module for the draw length you want, still usually without a press. A cam change means a new cam and a press visit. Check which applies before assuming a used bow will fit you.
Measure your draw length before you shop, not after. The wingspan method is wingspan in inches / 2.5, rounded to the nearest half inch, and our draw length calculator runs it with a sanity check. Have the result confirmed at a shop with your actual release aid, because switching between a wrist strap and a handheld release changes effective draw length by roughly a quarter to a half inch.
What the speed rating really means
The 350 fps figure is an IBO rating, measured at a 30 inch draw length, 70 pounds of draw weight, and a 350 grain arrow. Almost nobody shoots that combination, so treat the number as a way to compare bows against each other rather than as a speed you will see on a chronograph.
As a worked example, a shooter at a 28 inch draw, 60 pounds, with a 425 grain hunting arrow would expect roughly 285 fps from this bow. That estimate applies the standard corrections of about 10 fps per inch of draw under 30, about 2 fps per pound under 70, and about 1 fps per 3 grains of arrow over 350. String accessories such as a peep and a nock set cost a few more. Run your own build through the arrow speed calculator and chronograph it if you need a number you can sight in against.
Who the Bowtech SR350 suits
- 3D shooters and hunters who want to change the draw cycle for the season.
- Archers who want speed without dropping to a short axle to axle bow.
- The 6 inch brace height is the cost of the speed rating.
Brace height is the quiet forgiveness spec. At 6 in, this bow sits at the fast, unforgiving end, which rewards an established anchor and punishes form errors. Axle to axle length works alongside it: see short vs long axle to axle bows for how the two specs interact.
Setting up arrows for this bow
Arrow spine is driven by your draw weight, arrow length, point weight, and cam aggression, not by the bow model alone, so there is no single correct shaft for any bow. Run your actual numbers through the arrow spine calculator and check the result against the spine chart before ordering a dozen shafts. Remember that spine is dynamic: a heavier point or a longer shaft both weaken it.
Safety minimum. At this bow's 70 pound peak weight, total arrow weight must stay at or above 350 grains, which is the industry standard of 5 grains per pound of draw weight. Shooting lighter leaves too much stored energy in the limbs rather than the arrow, which risks damaging the bow and voids most warranties. Build your real total with the total arrow weight calculator, counting shaft, insert, point, nock, wrap, glue, and vanes. Have any setup work you are unsure about checked by a qualified pro shop.

Frequently asked questions
How fast is the Bowtech SR350?
Bowtech rates the SR350 at 350 fps IBO. That figure is measured at a 30 inch draw, 70 pounds, and a 350 grain arrow, which is faster than almost anyone actually shoots. Expect roughly 10 fps less for every inch of draw under 30, about 2 fps less per pound under 70, and about 1 fps less for every 3 grains of arrow over 350. A typical hunting setup lands well below the published number.
What is the draw length range on the Bowtech SR350?
The SR350 covers 25 to 30 in, a span of 5 inches. DeadLock binary cams with a rotating module in half inch increments. The FlipDisc flips the bow between Performance and Comfort draw cycles. Measure your own draw length before you shop, because a bow set outside your correct length will never anchor consistently no matter how well the rest of the setup is tuned.
What draw weight does the Bowtech SR350 come in?
Published draw weight is 50 to 70 lb. Offered in 50, 60, and 70 lb peak weights. Choose the weight you can draw smoothly while seated and without raising the bow above your head, not the highest number you can muscle once. Overbowing is the most common setup mistake in archery, and it damages form long before it damages anything else.
What is the minimum arrow weight for the Bowtech SR350?
At its 70 pound peak weight, the hard floor is 350 grains total arrow weight, based on the industry minimum of 5 grains per pound of draw weight. Going lighter leaves too much energy in the limbs rather than the arrow, which risks cracking limbs or cams and voids most warranties. Check the bow's own documentation as well, since some manufacturers set a higher minimum.
Is the Bowtech SR350 still in production?
No, the SR350 has been discontinued and is no longer in Bowtech's current lineup. It remains common on the used market, which is exactly why the specs matter. If you buy used, budget for a string and cable inspection, since strings age whether or not the bow has been shot.
How we choose: we compare published manufacturer specifications, verified owner reviews, and pro shop guidance. We do not test gear in person. Draw weight and arrow spine affect safety, so follow your bow manufacturer's specifications and have setup work checked by a qualified pro shop.
