I am having troubles finding the right load for my BLR .22-.250...As of right now some I am loading 50 gr Nosler BT with 36 gr. of Varget powder behind it. Also what have you found for an overall cartridge length that shoots the best for this gun. I know that not every gun shoots the same but will get me close to where I can play with the seating alittle bit. Does anybody else load a bullet for this rifle?? If so what seems to be working for you!! Thanks for your help....

Hello,
I have not loaded for your particular rifle, but have loaded the 22-250 for sometime now and used in long range matches, but with much heavier bullet than you are using for sporting/hunting use. However, might suggest that you determine twist of barrel on the Browning? Probably 12 or even 14, not sure what they use, but that would indicate using the bullet range of weight you are mentioning. You can give Sierra a call and they will be most helpfull on bullet selection. Now for OAL of loads, believe that it is magazine rifle and if you use magazine, that is the max. length of your cartridge. If single loading, different story. Have you measured the length of your chamber or determined just where the bullet touches the lands and grooves?? Browning may have used a long throat in the chamber, but if not using the magazine you would be able to seat bullet closer to the contact point and usually, not always, getting that bullet closer to the lands and grooves will give you better results on accuracy. Stoney Point offers a device which will let you measure the OAL w/ the lever or semi type rifle for the unit is angled to do so. Again, just a few suggestions.

I have a BLR 81 with a steel receiver in 223 that is a real shooter.
As mentioned I believe the magazine will limit the OAL. Finding the perfect load can be fun or it could be flustrating
Do the noslers have a max fps? I have blown Hornady SX bullets apart in flight from too much speed from a 22-250.
Again as said earlier double check your barrels twist rate, it may dictate the bullet weight you need to use.
If all else fails
SELL IT TO ME!!
I am confident you will not fail

Well the rate of twist is 1:14 for my rifle....Can someone tell me how the grain of bullet reflects on the amount of twist there is in the barrel?? Thanks a bunch!!

Hello,
The impact that rate of twist has on the bullet, projectile, is very simply put(could not do it any other way!!) imparts a spin or rotation to the bullet to bring about stability in flight. Now, as to all the physical things that occur during a bullets flight would be best left up to the experts. Let me suggest Sierra for they have as much research on such items as anyone other than the military. The Sierra manual has a great deal of info on this topic. Favor Center!!

I know what the rifling in a barrel does but my question is that someone stated that the grain of bullet is based off the twist rate of that particular gun....So with a 1:14 rate (20" barrel) explain to me what you mean by this....

Thanks for any responses!!

Have you figured out what the rifle likes to shoot yet??

I know this sounds like heresy but try a different bullet. Your rifle should shoot bullets up to at least 60 grains well. Try the 50 or 55 grain Sierra soft points and IMR 4895. I have had spotty results with the ballistic tips in my 22 centerfires.

well I finally found an C.O.L to work for shooting the Nosler 50 gr. CT's. You can spend alot of time trying to figure out what C.O.L that shoots the most accurate out of your gun...I whipped up 20 rounds last night and am going to sight in today.....I have had the press for a year or so but I had so many of those 40 round varmint packs that Winchester puts out and wanted to use them up before I started to load...The funny thing is that them 45 gr hollow points shot great for being factory loaded???? Thanks for all your resposes!!

I imagine you'll do best with 52-55gr. bullets. There's nothing wrong with your load. I use the same bullet and Varget 36.8grs. and find it very accurate, but I'm shooting a bolt action rifle. I seriously doubt you'll do much better than 1" groups with a lever action. Browning makes a good gun, but that action simply doesn't make a great varmint rifle. I'd continue to use the same components you're using. but vary the powder charge up and down a bit, then select the charge that's most accurate. Maybe someone else knows a secret formula, but I seriouslt doubt it. Best wishes.
