INTRO:
I have put together this thread as an informative thread for the new guys or anyone else who needs help with selecting the correct .277 bullets for reloading for the Remington 6.8 SPC.Before I begin, I just want to touch up on the Remington 6.8 SPC. If you are using the 6.8 SPC in an AR-15, there is an OAL that you have to keep in mind. With the Barrett magazines, I would not load the ammo longer than 2.250″. With the C-Products, I would not load the ammo longer than 2.280″. If you have PRI magazines, I would not load the ammo longer than 2.295″. Also, due to the limited powder capacity, it is best to load bullets in the range of 90-135 Gr.

POWDERS:
After doing a lot of testing, I have separated the bullets into the following categories: 90 Gr. bullets, 100-115 Gr. bullets, 120-135 Gr. bullets, 90-115 Gr. bullets, and 90-135 Gr. bullets.

Best Powders for 90 Gr. Bullets:
If you plan on just using the 90 Gr. bullets, I would use the following powders:
1. Reloaders 7. (Extruded)
2. H4198. (Extruded)
3. X-Terminator. (Ball)
4. AA1680. (Ball)

Best Powders for 100-115 Gr. Bullets:
If you plan on just using the 100-115 Gr. bullets, I would use the following powders:
1. H322. (Extruded)
2. Benchmark. (Extruded)
3. Reloaders 10x. (Extruded)
4. 2015. (Extruded)
5. X-Terminator. (Ball)
6. AA2230. (Ball)
7. TAC. (Ball)
8. H335. (Ball)
9. N133. (Ball)

Best Powders for 120-135 Gr. Bullets:
If you plan on just using the 120-135 Gr. bullets, I would use the following powders:
1. H322. (Extruded)
2. Benchmark. (Extruded)
3. Reloaders 10x. (Extruded)
4. 2015. (Extruded)
5. X-Terminator. (Ball)
6. AA2230. (Ball)
7. TAC. (Ball)
8. H335. (Ball)
9. N133. (Ball)

Best Powders for 90-115 Gr. Bullets:
If you plan on just using the 90-115 Gr. bullets, I would use the following powders:
1. H322. (Extruded)
2. Reloaders 10x. (Extruded)
3. 2015. (Extruded)
4. X-Terminator. (Ball)
5. TAC. (Ball)
6. H335. (Ball)

Best Powders for 90-135 Gr. Bullets:
If you plan on using various bullets in the 90-135 Gr. range, I would use the following powders:
1. H322. (Extruded)
2. Reloaders 10x. (Extruded)
3. 2015. (Extruded)
4. X-Terminator. (Ball)
5. TAC. (Ball)
6. H335. (Ball)

BULLET TYPES:
1. FMJ-Full Metal Jacket (Ball Ammo). Unknown at what velocity the Remington FMJ fragments, but the SSA Extreme FMJ is supposed to fragments at 2100+ fps.
2. OTM-Open Tip Match.
HP-Hollow Point.
SMK-Sierra Match King. Generally fragments at 1900+ fps.
3. SP-Soft Point. Generally expands at 1900+ fps.
4. BT-Ballistic Tip. Generally expands or fragments at 1900+ fps.

NOTE: You may see the letter “BT” (Boat-Tail) in front or after the above ammo types. BT stands for “Boat Tail” and refers to the base of the bullet. A “Boat Tail” is a sloping end which narrows gently at the base of the bullet, so that the cross-section resembles the shape of a boat’s hull. The boat tail shape reduces drag on a bullet, helping it to retain velocity and resist deflection from crosswinds, but causes the bullet to take longer to “settle” after leaving the barrel compared to a standard “flat-base” bullet. Boat tail bullets are usually selected for long-range shooting, while the flat-base bullet shape tends to be more accurate at short ranges. A “HPBT” bullet is a “Hollow Point Boat Tail” bullet.

The last thing I would like to explain is a Cannelure. A Cannelure is a cut or pressed groove (or grooves) around the shank of a bullet. Cannelures provide an area into which the case mouth may be securely crimped. Military ammo has cannelures to prevent bullet set-back. Bullets with cannelures are not generally used in match ammo because cannelures may decrease the accuracy of the bullet. For Military/LE purposes, bullets with cannelures are preferred. For sniper type applications, bullets without cannelures are usually used.

    I am loading the H V-max 110 gr. with the H322 powder. I was looking to get the Sierra 130 since it is identical length. I have a 4 grove 1-11 twist SPC II. How many grains of powder did you start with on the Sierra 130 with the 322 powder?

    • The correct answer would be to start with 25gr, but that will be too slow. Start at 27 and work up to 29gr. Some guys have pushed them faster than that. I’d get the flat base ones istrad of the BTHP ones.

  3. Robert says:

    I am looking to definitely use the Spitzer because the boat tail is so much longer. Thank you for your help.
